CROP SCENE INVESTIGATION – 38: What’s behind the weed escape in Scott’s soybeans? – SOLVED

by BERNARD TOBIN

Weed resistance was the cause of Scott’s foxtail escapes featured in our March 2012 issue. What agronomist Pat Lynch found in his field was Group 2 resistant foxtail.

The clue to the mystery was contained in the dead and dying weeds that could be found beside the green, vigorous foxtail plants.  A close look revealed that many foxtail plants had turned red and purple and were dying – the classic death symptoms of foxtail that are not resistant to Group 2 graminicides.
