A lot of reports of cotton injury from post applied Dual Mag or Warrant over the past several days. This is not unusual as we have this issues to some degree every year. Continue reading
This is now a critical time for Palmer amaranth control in soybean and cotton. Judging by rating our pre applied herbicide performance in those crops as well as calls from folks walking fields it is very apparent that pigweed is starting to break through. Continue reading
