Caption: Soybeans in R5 stage. Note the small seeds in the topmost pod.
Caption: In the dry portions of my area, insect tip feeding damage is evident particularly along field edges.
Caption: In areas where heavy rains have fallen in the past couple of weeks, Red Crown Rot is beginning to show up.
SYNOPSIS

Soil moisture conditions across the three counties vary from wet to moderate drought. Rainfall has been quite variable across this area.

Soybeans planted in April are in the R5 (full pod) stage. The April-planted corn is in the R4 or R5 stage. Crops look good even in the dry areas at this time.

Weed control has been very good. I have noticed that conventionally farmed soybean fields with weed issues typically only have a problem with one weed group—either the Amaranthus family or velvetleaf (Abutilon theophrasti). Grassy weeds have not been an issue across the area in conventionally farmed fields.

Mildly Dry (soil is drier than normal, plant growth may have slowed)
IF CONDITIONS ARE ON THE DRY END, WHICH OF THE FOLLOWING US DROUGHT MONITOR CATEGORIES BEST FIT CURRENT CONDITIONS
Abnormally Dry (D0)
