SYNOPSIS

Champaign county received 1.5–2″ of rain this past week with more projected to come through the weekend. High temperatures have ranged from the 70s to 80s with lows in the mid-50s/60s. Some smoke from the Canadian wildfires has persisted for the past week and a half. Most corn and soybean planting is complete, with post herbicide applications underway in both crops. Soybeans are at V1–V4 and corn is at V2–V7, with early-planted corn nearing row closure. Rapid Growth Syndrome (RGS) is being observed in certain corn fields. Waterhemp pressure is still a concern, along with increased giant ragweed and cocklebur pressure, prompting adjustments in post herbicide programs.

WHICH OF THE FOLLOWING BEST DESCRIBES CURRENT CONDITIONS IN THIS COUNTY?
Mildly Wet (soil is wetter than normal, local vegetation is healthy)
WEATHER

We received 1.5-2″ rain on June 3rd-4th. More rain expected this weekend. Temperatures have been in the 70-80s for highs with lows in the mid 50s. Also been dealing with some smoke from the Canadian wildfires for the past week in half.

FIELD ACTIVITIES

Before the rain on Tuesday, most have been spraying post herbicide applications on corn and beans. Planting is pretty much wrapped up with a few seed corn acres getting planted this past week. Corn sidedress applications have been in full swing.

SOYBEAN GROWTH STAGE

Soybeans are in the V1-V4 growth stage.

CORN GROWTH STAGE

Corn is in V2-V7 growth stage. Early planted corn is starting to close the row reaching the V6/V7 growth stage. Rapid growth syndrome (RGS) is showing up in corn, with warm temperatures and moisture corn is growing fast. Sulfur deficiency has been noticed too.

WEEDS

Waterhemp continues to be a problem, waterhemp is getting decent size (2-6″) in some fields which have led to reevaluating post herbicide mix/rates. Also noticing more giant ragweed and cocklebur this year.
