Protection of cob maize stored in cribs

Abstract

A crib experiment with dust treatments of cob maize showed that a treatment with 8 oz. of 0.4 per cent gamma BHC in diatomite to 9 cu. ft. of cob maize provides an almost complete protection against insect damage over six months. A product containing pyrethrum in diatomite also gave good results. The distributionof damage and the moisture content in the crib with different treatments is shortly discussed.
