Welcome to the Penn State Pesticide Education Program blog. This is our first attempt at something like this so bear with us. We hope to have a new blog post at least once a week with topics such as: upcoming meetings/events, category specific topics, core topics, highlight someone we work with, promote a great resource, and maybe even have a few guest bloggers.

Time to Check Your Boom Sprayer Calibration

Posted on May 13th, 2013 by Bill Riden in Applicators, Consumers

This blog is written by Bill Riden, our Pesticide Education Specialist.

Successful pesticide application requires proper calibration of your application equipment. Applying the correct rate of pesticide is of the utmost importance. If you apply too little pesticide, you may have poor pest control. You can also incur additional costs if re-treatment is needed or if you suffer crop loss because of lack of control. If you apply too much pesticide, you could damage the crop, be fined for illegal applications, and end up with too much pesticide residue in the crop and soil. You have also wasted money by using too much of the pesticide. Calibrating your application equipment to know the pesticide is being applied at the right rate and in a uniform pattern is well worth your time.

Boom Sprayer Calibration

The most convenient boom sprayer calibration procedure is the “1/128th acre” method. The basic principle is to determine the calibration distance to cover 1/128th of an acre based on the spacing of the spray nozzles. When you determine how much water is coming out of the nozzle to cover 1/128th of an acre, you multiply that number by 128 to determine how many ounces would be coming out to cover 1 acre. The beauty of this method is illustrated in this example. If we have 1 ounce coming out over the course of 1/128th of an acre, multiplying this by 128 would give you 128 ounces. This is equivalent to 1 gallon. Because there are 128 ounces of liquid in 1 gallon, this convenient relationship results in ounces of liquid caught from one nozzle being directly equal to the application rate in gallons per acre, or GPA. So the conversion is made automatically for you, this is true regardless of the number of nozzles on the boom.

Equipment Needed for Calibration

  • Tape measure or measuring wheel
  • Flags or stakes for marking distance
  • Calibration cup or other graduated collection container
  • Stopwatch or watch with a sweep second hand

Calibration Steps

Step 1. Clean the sprayer before calibrating.

  1. Away from any wells or water supplies, rinse the spray tank thoroughly and fill the tank half full with water.
  2. Remove nozzles, screens, and in-line strainers. Clean them in soapy water with a soft brush.
  3. Start the sprayer and flush hoses and boom with plenty of water.
  4. Turn sprayer off, put nozzles back on boom. All nozzles should be the same size and type.
  5. Restart the sprayer; adjust pressure for proper field application. Inspect nozzles for proper spray pattern. Replace any nozzle that produces an irregular spray pattern. Recheck for even patterns.

Step 2. Check nozzles for uniform output.

  1. Using a calibration cup (or a graduated container marked in ounces) catch the output from each nozzle for 20 seconds and write down the number of ounces.
  2. After catching the spray from every nozzle, add the amounts caught and divide by the number of nozzles to get the average output per nozzle.
  3. If the output from any nozzle is more than 10 percent above or below the average, clean or replace that nozzle.
  4. Recheck the output from any cleaned or replaced nozzle. Use the new output to figure a new average. If more than 2 nozzles have output rates 10 percent above or below the average, replace all of them, and repeat steps 1, 2, and 3 to be sure the flow rate is uniform.

Step 3. Calibrate the sprayer.

  1. Use Table 1 below to find the distance you must travel to cover 1/128th of an acre per nozzle. This is done by measuring the nozzle spacing on the boom, and then check the chart for the distance needed for the calibration. Mark off this distance in the field, allowing space for the sprayer to reach full operating speed before reaching the first marker of the test course.
  2. Fill the tank half full with water (no pesticide). Make at least two runs over the marked distance with all the equipment that will be used during the application. Use the gear and throttle settings that will be used during the actual spraying. Figure the average time in seconds the sprayer takes to travel the marked distance.
  3. Park the tractor and adjust sprayer pressure to the level that will be used for application. Using a container marked in ounces (calibration cup), catch the output from a single nozzle for the length of the average travel time. The number of ounces collected from one nozzle is equal to the output of the entire sprayer in gallons per acre (GPA).
  4. Compare the actual application rate with the recommended or intended rate. If the actual rate is more than 5 percent higher or lower than the recommended or intended rate, you must make adjustments.
  5. Start the adjustments by changing the pressure. Lowering the spray pressure will reduce the spray delivered; higher pressure means more spray is delivered. Remember not to vary from the pressure range recommended (by the manufacturer) for the nozzles in use.
  6. Another way to correct the application rate is by changing the actual travel speed. Slower speeds mean more spray is delivered; faster speeds mean less spray is delivered.
  7. If these changes do not bring the application rate to the desired rate, you may have to select a new set of nozzles with smaller or larger orifices.
  8. Recalibrate the sprayer after any adjustment.

Scammers Offering Pesticides at Great Prices–BEWARE!

Posted on April 8th, 2013 by Dave Scott in Applicators

Today’s blog is written by Dave Scott, Chief, Division of Health and Safety in the Pennsylvania Department of Agriculture.

Phone and email scams happen every year, and every year people get cheated out of a few hundred dollars or worse. And unfortunately, the items being sold range from everything from insurance, medicines, vacations, to even pesticides. We all need to be wary when responding to these offers.

The Scam

Recently a situation was brought to the attention of the Department of Agriculture. A farmer first called Penn State Extension who then relayed the information to a PDA Regional Office. This farmer received a call from a gentleman named “Matt,” who was trying to sell him a herbicide called “Trilene” for his farm. The farmer’s number is unlisted and the salesman was not forthcoming and very pushy throughout the call. The salesman made claims that the product would control broadleaf weeds in his fields for three years.

The salesman (Matt) wanted the farmer’s credit card number and grew impatient when the farmer told him that he wanted to check with his son before purchasing anything. Matt did provide the farmer with a phone number to call back, but a reverse phone look-up did not disclose the owner of the number. If the Extension office would try to call, they come up on the Caller ID as “Government Entity” so no one would probably answer. Other farmers may be facing a similar scam in our area.

Tips to Keep in Mind

The Pennsylvania Department of Agriculture recommends you only deal with companies and dealers that you know and trust. It is NEVER a good idea to provide any personal information or credit card information to any unsolicited phone or email requests.

  • Out-of-state and off shore companies are hard to track down for returns or refunds.
  • Even if you receive the pesticide or other product,  it rarely meets the advertised claims.
  • The active ingredient in these products can generally be purchased locally for a lot less.
  • Remember, if it is too good to be true, it probably is.

If you find the sales pitch hard to resist–Do your homework–ask for a phone number to return their call, get the address of company, the product name, active ingredients, and EPA registration number of the product. Also, ask for product warranty information and a written offer with an address to mail in the payment. Then check out the company and the product you are considering by checking with Penn State Extension, neighbors, and local dealers. You can also look up the pesticides that are currently registered for use in Pennsylvania. Go to http://state.ceris.purdue.edu/, select Pennsylvania, and then use the search criteria to ensure that the product in question is actually registered for sale in Pennsylvania.

Finally, just be careful! Scammers will sometimes pose as working for legitimate companies–when reviewing websites, look for inaccurate information as not all companies with the same name are the same. And only order when you are sure it is a good deal. And again, if it is too good to be true, it probably is!

Until next time,
Be Safe!

The Material Safety Data Sheet vs. the Safety Data Sheet

Posted on March 11th, 2013 by Kerry Richards in Applicators

This blog is written by Kerry Richards, the Penn State Pesticide Education Program Director.

OSHA’s Hazard Communication Standard Move to Align with Globally Harmonized System of Classification and Labeling of Chemicals (GHS)

Under its Hazard Communication Standard (HCS) (29 CFR 1910.1200), the Occupational Safety and Health Administration (OSHA) requires  Safety Data Sheets (SDSs) for all hazardous chemicals.   In March 2012, OSHA published a final rule to align its HCS regulations with the Globally Harmonized System of Classification and Labeling of Chemicals (GHS). The primary goal of GHS is improved protection of human health and the environment by providing chemical users and handlers with enhanced and consistent information on chemical hazards. The GHS is based on major existing systems for industrial chemicals, pesticides, consumer chemicals, and chemicals in transport, but implementation of the GHS would require some changes in all existing systems in order to achieve harmonization.

However, it is important for growers who use federally regulated pesticides to note that the Environment Protection Agency (EPA) has not yet moved to amend its pesticide labeling regulations under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) to align with the GHS. The differences between EPA’s current requirements and the GHS are related to classification criteria, hazard statements, pictograms, and signal words. For example, FIFRA pesticide product labels may contain the following signal words: of “Danger Poison with the skull and crossbones graphic,” “Warning,” or “Caution” depending on the toxicity level of the product, and “Danger” for a product that may be a potential skin or eye irritant. The GHS uses only two signal words, “Danger” and “Warning.” To illustrate, the label of a chemical that has an oral LD50 of 550 mg/kg bears the signal word “Caution” under current FIFRA labeling practices but would require the signal word “Warning” under the GHS.

For pesticide products, FIFRA labels approved by EPA pre-empt OSHA’s label requirements, but not the requirements for SDS and worker training (except for certified applicators and agricultural workers for whom EPA has training requirements). EPA realizes that this may require users of the SDS that are prepared for pesticide products to become familiar with two different systems, at least until the agencies’ requirements are harmonized. As a result, EPA issued guidance in the April 20, 2012 Federal Register to manufactures so that when changes are made to the SDS to meet the OSHA requirements, the new SDS format will also be in compliance with the pesticide regulations under FIFRA.  This guidance is commonly referred to as Pesticide Registration (PR) Notice 2012-1.

Why the switch from MSDS to SDS?

For many years under the HCS, this last responsibility was met by maintaining a copy of the Material Safety Data Sheet (MSDS) for each product that was considered a hazardous chemical, some of which are pesticides. Under the Haz Com 2012, the MSDS will be replaced with a Safety Data Sheet (SDS). Before the Haz Com 2012, there were several acceptable MSDS formats. OSHA’s adoption of Global Harmonization Standards (GHS) requires the use of a single format with 16 sections that appear in a specific order. Although this change seems to have become a cause for concern, in all practical reality, there is very little difference between the two documents.

Will the change require that both and MSDS and an SDS be kept for the same product?

For compliance with the new OSHA Haz Com 2012 regulatory requirements, maintaining both an MSDS and a SDS for the same chemical is not necessary. In the next few years as the SDS becomes available for individual products, they will replace the existing MSDSs. Although there is no requirement to keep the older MSDS once it is replaced with an SDS, a good management practice would be to keep an electronic copy on file, especially if existing stocks of the chemical were purchased under the older MSDS.

However, when the chemical in question is a pesticide and the content of the MSDS and the SDS differs, a copy of both documents must be maintained to ensure compliance with OSHA HazCom 2012 and FIFRA which regulates pesticide products.

Kindergarten through 8th Grade — START DRAWING!

Posted on February 11th, 2013 by Christina Becker in Announcements, Consumers

This week’s blog is written by Christina Becker, an Extension Specialist in the Penn State Pesticide Education Program. Chris coordinates the statewide Poison Prevention Outreach Program for our office, which is well underway for March 2013.

Make Posters for the 2013 Poison Prevention State and National Poster Contests

...to draw a Poison Prevention Poster!

Nationally, March is Poison Prevention Month and March 17 -23rd is officially Poison Prevention Week. During March, focus is placed on a greater awareness of accidental poisonings and prevention. Families are encouraged to review and adopt safe practices to limit potential hazards around the home to help reduce the risk of poisoning. Poison Prevention Month, Week, and the National Poison Prevention Poster Contest programs are all sponsored by the Poison Prevention Week Council to help promote the educational message.

In Pennsylvania, the Penn State Pesticide Education Program in cooperation with the Pennsylvania Department of Agriculture (PDA) offers the PA State Poster Contest as a supplement to a Poison Prevention Outreach program for 1st grade students throughout March. The state poster contest replicates the national contest and is available to students in the same grades. The Pesticide Education Program’s Poison Prevention Outreach is entering its third year and is scheduled to reach 12,000 first grade students in over 130 schools.

Students in Kindergarten through the 8th grade are eligible to enter both the PA State and National Poison Prevention Poster Contests. The two contests are very similar in requirements but do have different submission deadlines and slightly different options to enable entry into both contests. At the state level, we have provided additional options for submission so that children can enter posters in both contests. For more information, visit our Poster Contest web page.

Encourage children to start drawing now!

Get creative!

Children can draw and submit a poster at any time now. And if possible, submit a poster to each contest.

The National Contest has a postmarked deadline of March 24, 2013. Click on the National Contest Guidelines for information about poster submissions. An Artwork Submission Form must also be printed out, completed, and attached to the back the poster.

Eligible children are also encouraged to submit a poster to the State Poison Prevention Poster Contest. The PA State Contest entry deadline is May 1, 2013. We are providing three options for poster submissions to the state contest.

  • Create an original poster for the PA State Contest (and for the National Contest if you want). Be sure to attach the Submission Form to the back of each poster.
  • Create an original poster for the National Contest and make a good copy of the original poster (and Submission Form) to submit to the PA State Contest.
  • Create an original poster for the National Contest and take a high-quality photograph of the poster (and Submission Form) to submit to the PA State Contest.

Those options are explained further in the PA State Poster Guidelines. REMEMBER: Both the State and National poster submissions must include a completed Artwork Submission Form attached to the back (unless photographed).

Winners Will Be Recognized!

2012 Poster Contest Winners

Last year, during the second year of the State Poster Contest, over 450 posters were submitted and then we forwarded all those submissions on to the national Poster Contest. In January, four students were recognized at the Pennsylvania Farm Show for winning the PA State Poster Contest. Check out their story at: http://blog.pested.psu.edu/2013/02/04/2012-state-poster-contest-winners-recognized-at-pa-farm-show-in-january-2013/.

One of our own, a Pennsylvania student from Mercer County, won the grade K-2 Division of the National Poster Contest! Check out his story at: http://blog.pested.psu.edu/2012/11/06/mercer-county-student-takes-top-honors-in-the-national-poison-prevention-contest/.

By encouraging entry into the contest, a greater number of people will become aware of poison hazards and prevention practices helping to keep more Pennsylvania children and families safe from accidental poisoning. Who knows, it might even showcase another Pennsylvania child as a National Winner!

Until next time,
Be Safe!

The AEE Student Teacher Workshop: Exploring Pesticide Education with an Incredible Group of Young Educators

Posted on January 28th, 2013 by Kelly Over in General

Kelly Over, our Education Program Assistant, starts off our 2013 blog with a recap of a recent workshop done for the Penn State Agricultural and Extension Education student teachers.

The Penn State Pesticide Education Program (PEP) is grateful for partnerships with the Pennsylvania Association of Agricultural Educators and Penn State Agricultural and Extension Education, enabling a learning exchange of pesticide safety lessons for general agricultural science curriculum and preparation for pesticide applicator certification. In early January, PEP was able to work with a dynamic group of young educators: the 2013 Agricultural and Extension Education (AEE) student teacher class!

The class participated in an all-day pesticide education workshop, including an introduction on pesticide regulations, integrated pest management lessons, pesticide toxicity and personal protective equipment exposure overview, and pesticide label instruction. The educators learned about these pesticide core topics and participated in hands-on activities.

The educators were able to view our brand new calibration videos! On the Pesticide Education YouTube site, we added our new video on backpack sprayer calibration and a new video on rotary spreader calibration. Each segment provides a calibration overview and a step-by-step example. Additionally, the student teachers saw the Plant Identification website, developed by the Penn State Center for Turfgrass Science. The website can be an awesome classroom tool, featuring approximately 45 broadleaf weeds and 25 grasses and sedges, and outlining the plant’s biological information, as well as showing an image gallery and video for each species. Student teachers also got an in-depth look at the Educator section of the PEP web site, including the Ag and Science Teachers link, which shares classroom demonstrations and lesson ideas, some of which the educators participated in as shown below in a pictorial account of the day.

Renewal of Pesticide Dealer License

Posted on December 17th, 2012 by Bill Riden in Applicators

All licensed pesticide dealers in Pennsylvania should have received (or will be receiving soon) their renewal notice for the 2013 Pennsylvania Pesticide Dealer License. One of the changes on this year’s renewal is the requirement to have a certified dealer manager on staff.

The new pesticide regulations effective December 11, 2012 require any person attempting to purchase a restricted use pesticide for resale or distribution to have a current and valid pesticide dealer license. The purchase and sale of restricted use pesticides also requires the dealer to have at least one certified dealer manager on staff at each dealer location.

A point of clarification, this year’s dealer license renewal requires the dealer to have a certified dealer manager if they want to renew their license. That is correct.  However, if the dealer only sells general use pesticides, the pesticide dealer license is not required. A pesticide dealer license is only required by a dealer buying and selling restricted use pesticides.

Please contact Bill Riden, our Pesticide Education Specialist at wmr11@psu.edu, if you have any questions or need more information.

Until next time,

West Nile Virus in 2012: A Year to Remember

Posted on November 12th, 2012 by Sharon Gripp in General

It is November and we can finally say good-bye to Pennsylvania’s West Nile Virus season. 2012 will be remembered for the early horse detection in March and the record number of positive detections since surveillance started in 2000.Unfortunately for the human victims of West Nile Virus, some may be living with the serious effects of encephalitis for many years.

Final 2012 Surveillance Numbers for Pennsylvania

West Nile Virus was first found in the United States in 1999 in New York City. Surveillance was then started in Pennsylvania for the 2000 season. After a high detection rate in 2003, West Nile virus seemed to simmer down. In 2010 positive detections in mosquito samples exceeded 1,000; however, the other detections in humans, birds, and veterinary seemed to remain stable. All that  changed in 2012, when positive mosquito detections exceeded 3,400! Human and veterinary detections were the 3rd highest and bird detections was 4th highest since 2000. The data in the table below came from the surveillance reports on Pennsylvania’s West Nile Virus Control Program website.4

Mercer County Student Takes Top Honors in the National Poison Prevention Contest

Posted on November 6th, 2012 by Christina Becker in Announcements, General

This week’s blog is written by Christina Becker, an Extension Specialist in the Penn State Pesticide Education Program. Chris coordinates the statewide Poison Prevention Outreach Program for our office, which is quite an undertaking. Not mentioned in the blog below is that last year, the program reached over 8,000 kids! Chris has already begun her planning for next year’s program.

Colby Johnson is a national Poison Prevention Poster Contest Winner!

Colby Johnson, age 7, of West Middlesex, never imagined that the poster he created in March would win him the prestige of being a national poster contest winner for Poison Prevention, but win he did. What a wonderful surprise!

Colby, currently a 2nd grade student at Luther Low Elementary school in the West Middlesex School District, submitted his poster (pictured on left) in recognition of National Poison Prevention Month in March. Students were encouraged to make a poster for the state and national poster contests as a complement to an educational presentation focusing on poison prevention. Throughout the month of March, Master Gardeners presented this outreach program, designed by the Penn State Pesticide Education Program. Although only 1st grade students received the lesson, the poster contest was open to students in grades K-8.

October is Children’s Health Month!

Posted on October 29th, 2012 by Kelly Over in Consumers

Kelly Over, our Education Program Assistant, wrote this week’s blog. She helps coordinate our outreach educational programming.

Keeping children safe and healthy should always be a top priority. This blog highlights the importance of protecting children around the home, including pest prevention, pesticide safety, and even Halloween safety tips!

Why are children more susceptible to environmental risks than adults? Children’s bodies are still developing, which lessen a child’s ability to detoxify harmful substances compared to an adult. Additionally, children breathe in more air than adults, allowing a greater chance for potential inhalation exposure. Children’s behaviors also create additional risk for oral exposure, for example hand-to-mouth touching. Children tend to crawl on the floor and spend more time outdoors, which is great for physical activity, but can put them at risk to come into contact with pests and pesticides.

Prevent Pests

Pests in your home are certainly unwanted, but can also pose a health threat. “Decaying cockroaches and mouse dander are among the top triggers in asthmatic children.”1 Just like humans, pests need food, water, and shelter. By trying to eliminate pests’ accessibility to these critical needs, parents can try to keep out pests. Below are some cultural control tips to help prevent pests in the home.2
