Cotton Harvest-Aid Trials in Central Texas

Robert G. Lemon, Thomas A. Hoelewyn, Tom J. Gerik and Kyle L. Faver


Harvest-aid chemicals prepare the cotton crop for harvest by reducing/eliminating foliage and plant moisture that interfere with mechanical harvesting operations. Desiccation of the entire plant is necessary in regions where cotton is stripper-harvested. The voluntary removal of arsenic acid from the marketplace in 1993 has left many growers searching for an effective, economical replacement. Producers in central Texas currently spend abut a $100/acre in harvest costs -- $15 harvest-aid chemicals, $35 stripper harvest, $50 ginning. Environmental and crop conditions have direct influence on response of harvest-aids. Year-to-year variation is expected and annual harvest-aid field trials are essential in determining proper product selection. The objectives of this research were to evaluate the efficacy of currently registered harvest-aid compounds and experimental materials and to assess the response of Cyclone (paraquat) applied at different times of day.
