We sent these samples to Dr. Bryan Young at Purdue University to determine if they had the PPO resistant gene. Continue reading

A few years ago clethodim was rarely used in Tennessee but in the last couple of years that has really changed. Clethodim has become the tankmix of choice with glyphosate to control glyphosate-resistant (GR) ryegrass, johnsongrass, goosegrass and in some areas, barnyardgrass. Continue reading
A reminder that moth trapping data for corn earworm, tobacco budworm, and southwestern corn borer are posted weekly on this website. Look for “Moth Trapping Data” on the quick links menu to open an Excel file with the trapping data. Moth catches were low for all species last week.
There have been a number of calls where folks have asked my thoughts on “creative” PRE applied herbicides for soybeans. Continue reading
