The extent of the disease in the state is the worst one ISU Extension pathologist says she has ever seen. Farmers in 17 other states have also confirmed the disease.

Short-stature corn is often planted at higher populations because its architecture allows for better light interception and more efficient use of resources when plants are grown closer together. But that’s not always the case, according to Ken Ferrie, Farm Journal Field Agronomist.

More than 1,000 farmers across the country weighed in via survey to express concern that access to glyphosate and atrazine is at risk, after both technologies were called out in the MAHA Report. The next report, the MAHA strategy recommendations, is due to President Trump by August 12.

Just as corn growers were ready to put their pollination problems behind them, another one comes along. This time, the issue had to do with moisture occurring at the wrong time, and the results are significantly impacting yield.

EPA Administrator Lee Zeldin proposes rescinding the 2009 Greenhouse Gas Endangerment Finding. If the proposal goes into effect, it could potentially lead to DEF systems no longer being required in tractors, trucks and other equipment using diesel-powered engines — a decision many farmers and others in the ag community would applaud.

Some growers are considering rescue treatments with post applications of products. But as the calendar turns to August and the crop enters reproductive stages, that can be a risky undertaking at best, agronomists say.

Got tar spot? Economic data shows two passes can offer ROI, depending on the hybrid. However, if your crop got dinged at pollination that’s a different scenario and might require a revised game plan that takes yield estimates into consideration.

Both diseases are showing up earlier this summer than last year, according to Daren Mueller, Iowa State University plant pathologist. He says a new interactive tool from the Crop Protection Network can help farmers locate these diseases, and others, faster.

So far, the problem has been confirmed in four states. Agronomists are encouraging farmers to scout crops, estimate yield impacts in affected fields and determine whether to make adjustments to marketing plans.

This year’s program features all new agronomic content to help farmers grow and harvest high-yielding crops. Two of the key sessions: selecting a corn planter that’s right for your farm, and developing a systems approach to success with early-season soybeans. We look forward to seeing you there!
