New Herbicide Classification Chart (Prostko)

The Take Action Pesticide-Resistance Management Program has recently updated their herbicide classification chart.  This chart has 2 sections including a color coded mode of action/site of action chart and pre-mix herbicide product chart.  This is a very good reference material to have in your office or truck. 

Take Action is a farmer-focused educational platform designed to help farmers manage herbicide, fungicide, and insect resistance. Take Action started with industry-wide collaborative discussions about the growing threat of herbicide-resistant weeds. Parties included representatives from major ag chemical companies, land-grant university weed scientists, and soybean/corn/cotton/sorghum/wheat commodity groups.  Resource development for Take Action on Weeds is funded through a United Soybean Board grant.

A copy of this herbicide classification chart can be downloaded from the following web location:

Additionally, I have 100 hard copies of this chart in my office and these are available to anyone who wants one on a first-come/first-serve basis. Just let me know.

New Pesticide Data Program Summary (Prostko)

 I am always on the hunt for positive information about the use and need for pesticides in agriculture.  In November of this year, the USDA/AMS released its Pesticide Data Program's 33rd Annual Summary (2023).  This report provides high-quality data on pesticide residues in food, particularly foods most likely consumed by infants and children.  A few highlights of this report are as follows:

1) 9,832 food samples were collected.

2) Fresh and processed fruit and vegetables tested during 2023 were: almonds, apples, avocados, baby food applesauce, baby food carrots, baby food green beans, baby food peaches, baby food pears, baby food peas, baby food sweet potatoes, blackberries (fresh and frozen), celery, grapes, mushrooms, onions, plums, potatoes, sweet corn (fresh and frozen), tomatillos, tomatoes, and watermelon.

3) More than 99% of the samples tested had residues below the tolerances established by the EPA with 38.8% having no detectable residue.    

4) Residues exceeding the tolerance were only detected in 0.49% of the total samples tested.

5) A residue is any amount of pesticide that remains after an application.  A tolerance is the maximum amount of residue that may remain in or on food marketed in the US.  The US EPA determines the maximum residue levels (MRL’s) or tolerance of pesticides in food products based upon a standard 100-fold margin of safety to protect all people and the environment.  In addition to this base margin of safety, the Food Quality Protection Act (FQPA) of 1996 imposed an additional 10-fold safety factor to protect infants and children, unless sufficient evidence is presented to reduce.
