Abstract
This study was conducted to develop an economical control for the lesser cornstalk borer (Elasmopal pus lignosellus (Zeller)) on peanuts. To determine the effects of varying volumes of spray mixture on control, a constant amount of endrin Was applied in 20, 40 and 86 gallons of spray mixture per acre. A highly significant difference Was obtained between the treatments and the cheek in both the per cent of damaged peanuts and in the yield. No differences were attributable to variations in the volume of spray mixture applied per acre. To determine the dates at which insecticides should be applied to develop a satisfactory spray schedule, DDT was applied in combinations of single and double applications during the periods of moth flight in June, July and August. The per cent of injury was reduced significantly by the treatments. No significant differences in yield were observed between treatments. In an experiment in which insecticides were applied at 7-, 14-, and 21-day intervals, injury was reduced significantly by each of the treatments in comparison With the check. No differences were observed between treatments. The data on yields show no significant differences between the various treatments or between the treatments and the check.
