Caption: Pests like Japanese beetles 🪲 have started to clip silks during peak pollination.

SYNOPSIS

Corn fungicide applications have been in full swing, with planes, helicopters, and drones zooming through the air! Late last week and this week, the focus has shifted to soybean fungicide applications, typically done with ground rigs. Scouting continues to be a priority to monitor what is happening in corn and soybeans. Reports of wrapped tassels and other tassel-related problems have been a major concern. Producers and seed companies have scrambled to scout corn, as these issues have caused pollination problems in some areas. This is something we continue to monitor.

WHICH OF THE FOLLOWING BEST DESCRIBES CURRENT CONDITIONS IN THIS COUNTY?
Mildly Wet (soil is wetter than normal, local vegetation is healthy)
IF CONDITIONS ARE ON THE DRY END, WHICH OF THE FOLLOWING US DROUGHT MONITOR CATEGORIES BEST FIT CURRENT CONDITIONS
Near Normal (Dnada)
WEATHER

Temperatures have been uncomfortably warm and humid. Timely rains continues to bless us in our territory.

PRECIPITATION

In our territory, we have had variable rainfall events — from 4 inches to half an inch over the past week. A nice shower came through Knox County today, and it was no different, with southern Knox receiving substantially more than northern.

FIELD/SOIL CONDITIONS

Soils have good moisture.

FIELD ACTIVITIES

None at this point .

SOYBEAN GROWTH STAGE

Majority of soybeans are in that R2- R3 stage and have already had or getting close to optimum timing for fungicide/ Insecticide application.

CORN GROWTH STAGE

Corn is and has been in peak pollination over the past few weeks depending on planting date.

WHEAT GROWTH STAGE

Wheat 🌾 has all been harvested and was exceptional!! Double crop soybeans are off to a great start!!

INSECTS

I have not seen anything on my sticky traps.

In corn and soybeans, Japanese Beetles 🪲 continue to chew on leaves of the soybean plants and more concerning, clipping silks of the corn plants.

WEEDS

Waterhemp continues to poke up around the perimeter of field edges.

Pigweeds like Spiny Amaranth is starting to show up in our pastures where overgrazing has occurred.

DISEASES

I personally have not seen anything in soybeans to this point, BUT that is the goal! We don’t want to see any!! I do anticipate some white mold showing up later in the season here in Knox County.
As for corn….we have seen it all!! Northern Corn Leaf Blight, Gray Leaf Spot, Tar Spot, and Southern Rust!!

COVER CROP INSIGHTS

Cover crop discussions are being had over the past week. Plans to get aerial applications lined up to be applied between August 15th and September 1st. This will allow opportunity to maximize potential of these covers this fall.

OTHER

During this downtime, I have started reviewing updated soil tests to assess lime needs for fall, as well as sharpening the focus on seed as I walk plots to determine which varieties should be in the lineup for 2026.
