post on fungicides for hail damaged crops
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. …
Hoping for rain: crops at mid-season 2020
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.…

Frost/freeze damage report: will plants recover?
Temperatures over most of Illinois dropped to the upper 20s or low 30s on Saturday morning, May 9. This resulted in damage or even death to emerged and emerging corn and soybeans. The extent of damage was closely tied to when fields were planted.
Corn planted during the warm part of April—the first week—was up and growing (slowly) by May 1, with limited leaf area. In some fields, emerged stands were already subpar, especially in the wettest parts of the state,…
Replanting corn and soybeans
Both corn and soybean planting progressed at about normal speed into May, with 56 percent of the Illinois corn crop and 31 percent of the Illinois soybean crop planted by May 3. Unfortunately, the period of warmer, drier weather we have been hoping for has not yet materialized.
Over the ten days through May 5, about two-thirds of Illinois has gotten from 3 to more than 6 inches of rainfall. Temperatures have not cooperated very well,…

Planting corn and soybeans in 2020
March rainfall in Illinois ranged from normal to a couple of inches above normal, but the last week of March and first week of April have been relatively dry, and field operations are getting underway. The April 6 NASS report indicates that there were 3.1 days suitable for fieldwork in Illinois during the week ending on April 5, but no planting was recorded. As is often the case in early April, soils are wet over most of the state.…
