Effect of number of sprays on the rate of bollworm infestation, cotton yield and fibre quality (Lepidoptera)

, : Effect of number of sprays on the rate of bollworm infestation, cotton yield and fibre quality (Lepidoptera). Bulletin of the Entomological Society of Egypt, Economic Series (6): 93-102

Field studies were carried out in cotton plots in Egypt in 1961-62 on the effect of the number of spray applications (mixtures of azinphos-methyl (Gusathion) and endrin or DDT and endrin) on the control of the pink and the spiny bollworm (Pectinophora gossypiella (Saund.) and Earias insulana (Boisd.)) and on yield and fibre quality. The results indicated that a spray programme consisting of five applications (at intervals of 10 days) was better than one of two, four, eight or 11 applications.
