Abstract
Expts. conducted from 1946 to 1949 showed that early season applications allowed cotton plants to set bolls approx. 5 days earlier than those receiving late application. The removal of all blooms during a 22-day period slightly reduced the yields. Under the conditions of these expts., it is apparently more economical to attack injurious populations of insects as they appear than to apply insecticides early in the season plus the necessary later applications to protect the crop from weevils and bollworms.
