Recent fronts that have pushed through the state, giving relief to many areas that have been stressed by heat and a lack of water. That’s great for productivity, and also can impact diseases. A new post on the disease outlook and considerations can be found by clicking here.…
Finally some wet weather! That means finally some foliar diseases may start to pop up in our corn crop. Check out the new article by clicking here!…
That was one heck of a storm yesterday. Many fields throughout East central Illinois were severely affected by nickel sized hail. Although my three year old stated that we should, “use some tape” to fix the damaged tissues, some will consider fungicide applications. A new post on the subject can be found here. …
While the record will show that planting progress for both corn and soybean crops in Illinois was close to normal in 2020, heavy rainfall in May and again in early June in some places this year led to some replanting, and some ponded areas don’t have a stand. Stands are mostly good otherwise, but crop condition ratings in Illinois have been mediocre so far, with percent good + excellent percentage in the low 60s for both crops in early July.…
Spider mites often show up when it’s hot and dry outside. Given our current weather (and the promise of more heat to come), it’s a good time to review our scouting and management recommendations. Spider mites feed on a wide variety of plants, and usually enter soybean fields from grassy edges – especially right after the edges have been mowed, which causes the mites to seek out a new food source. (If you have the option,…
Wheat harvest marks the end of one cropping cycle and the beginning of a second. In parts of central and southern Illinois, farmers frequently opt to plant double-crop soybean following wheat harvest, with hopes that the first “killing” frost will be late enough to allow the soybean to reach maturity. Wheat stubble fields not planted with a second crop often become populated with a “crop” of summer annual (and sometimes perennial) weed species. Unlike double-crop soybean,…

The Illinois Department of Agriculture recently issued a document containing guidance “to help pesticide dealers, commercial pesticide applicators and farmers understand the U.S. EPA order and the State of Illinois extension of the cut-off date for application.” The document includes many frequently asked questions and how the Department interprets the guidelines from U.S. EPA for the continued use of existing stocks of these products whose registrations were vacated by a ruling of the Court of Appeals for the Ninth Circuit.…
On June 3, 2020, in National Family Farm Coalition vs. U.S. Environmental Protection Agency, Case No. 19-70115, the United States Court of Appeals for the Ninth Circuit issued a ruling immediately vacating the registrations of Xtendimax, FeXapan and Engenia, all of which contain the herbicide dicamba. On June 8, 2020, the U.S. Environmental Protection Agency (EPA) issued a final cancellation order for these three dicamba products. The final cancellation order can be found here: https://www.epa.gov/sites/production/files/2020-06/documents/final_cancellation_order_for_three_dicamba_products.pdf.

On June 3, 2020, the United States Court of Appeals for the Ninth Circuit issued a ruling immediately vacating the registrations of Xtendimax, FeXapan and Engenia. The Ninth Circuit ruled that USEPA’s registrations of those products violated The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). Pursuant to FIFRA, all pesticides sold, used, or distributed in the United States must be registered with the USEPA. Therefore, effective June 3, 2020, based on the Ninth Circuit’s ruling, Xtendimax,…
