Aug. 21 Recap
DuPont Pioneer Agronomy Report - Jeff Wessel
Eastern Route - Day 2
Starts in Fishers, Ind., and ends in Bloomington, Ill.
Crop Conditions for McLean and Tazewell counties in central Illinois
- Some cornfields started showing severe drought stress starting at the end of June and conditions haven't improved since then.
- Cornfields that I've looked at will probably yield between 50 and 180 bu./acre, with many averaging 100 bu./acre.
- Corn I've looked at is in the R5 stage, with some fields at least half way or further through the R5 stage. The crop isn't too far from being mature.
- In soybeans, the canopy remains in fantastic shape. Reasons why: beans were planted into excellent conditions and planted early, enabling soybeans to be pretty well rooted.
- Most soybean fields will likely yield between 35 and 70+ bu./acre (in a few instances).
DuPont Pioneer Agronomy Report - Chris Woerner
Western Route - Day 2
Starts in Grand Island, Neb., and ends in Nebraska City, Neb.
Nemaha & Otoe counties in southeast Nebraska
- Scouted an irrigated white cornfield and ears are pretty well filled out and yield will be good.
- Dryland acres look very tough in southeast Nebraska and yield will be variable. Scouted one white cornfield that will likely yield 50-60 bu./acre. Another field with a different soil type, different planting date but same white corn hybrid will probably yield 120 bu./acre.
- Disease pressure fairly light, seeing a little Southern corn rust and gray leaf spot (later in the season). Goss's wilt is not spreading much this year. In dryland corn, ear molds are showing up, especially Aspergillus ear rot, which has the potential to develop aflatoxins.
- Insects: Heavy earworm pressure, especially in later-planted fields; virtually no European corn borer and isolated cases of corn rootworm in some areas.
- Scouted fields of mostly Late Group 3 varieties and these plants have good pod set. Very few pods on the bottom 1/3 of the plant but overall these plants have decent pod sets. What happens to the top 1/3 of the plant will make the yield difference but these soybeans need rain in the next one to two weeks.
- Insect pressure: bean leaf beetles are hit and miss, seeing a few stink bugs
- Diseases: Phytophthora & fusarium showed up after mid-June rains. Late-season phytophthora, fusarium and charcoal rot showing up. Some SDS showing up late.
