We have been blessed with another great harvest season and it appears we may be able to finish harvest with little rain.  Here on the 5th day of Oct, I would guess the average cotton acre within the state has already received the first application of harvest aids and is very close to seeing a picker.  Even so, several acres have not been defoliated.  This has led many to call with concerns about the cooler temperatures in the forecast over the weekend and several have asked if it is simply time to defoliate based on calendar date.   Continue reading
