Cotton growers have traditionally applied chemicals throughout the season by either aerial application or ground sprayers. Selection of atomizers for pesticide application has gone from fine spray hollow cone to low-drift flat-fan type nozzles on ground sprayers for insect sprays. In recent years off target spray drift has come to the forefront. Drift reducing technology has been introduced for the flat-fan nozzles which have been used for herbicide application. A large percentage of cotton growers have migrated to Roundup technology for better weed control. This move has force growers to tank mixing insecticides with Roundup to keep the number of applications to a minimum thus saving spray application time and money.
