SYNOPSIS

Attending the Illinois Wheat Plot Tour provided valuable insights into wheat development and the progress of corn and soybean planting in Macoupin and Montgomery Counties. Overall, wheat is flowering and conditions appear favorable, with only minor occurrences of bacterial leaf streak and tan spot observed in the fields we visited. Based on head and spikelet counts, estimated wheat yields are 100.38 in Macoupin County and 89.59 in Montgomery County. Corn and soybeans are beginning to emerge and are in their early vegetative stages, although many fields have yet to be planted due to wet spring conditions.

WHICH OF THE FOLLOWING BEST DESCRIBES CURRENT CONDITIONS IN THIS COUNTY?
Moderately Wet (soil is damp, standing water may be present in low areas, water bodies are full)
WEATHER

Mid 70s and windy.

FIELD/SOIL CONDITIONS

Rains from the previous night left fields ranging from tacky to saturated. Minor ponding was observed in many fields in the area as they struggle to absorb the frequent rainfall this area has been experiencing.

FIELD ACTIVITIES

Our team of seven conducted head and spikelet counts across five fields in Macoupin and Montgomery Counties. To collect head counts, we placed a yardstick alongside a representative row and counted all the heads within that 3-foot strip. For spikelet counts, we took the average of 20 heads from the same 3-foot section. We also noted the row spacing in each field. Using our data, yield averages were estimated by the Illinois Wheat Association for each county.

SOYBEAN GROWTH STAGE

CORN GROWTH STAGE

VE-V2

WHEAT GROWTH STAGE

Flowering – beginning grain fill (10.5-11.1 Feekes)

INSECTS

DISEASES

Bacterial leaf streak and tan spot were noted in 3/5 fields visited between the two counties. Although observed, overall disease pressure was low.
