Abstract

Efforts to improve the effective use of B. thuringiensis and reduce its application costs has stimulated the development of higher potency formulation. Recent field studies have shown that a single application at 30 BIU/ha (12 BIU/acre) is as effective as the split double application of 20 BIU/ha (8 BIU/acre) formerly recommended. Also results of using volumetric application rates of less than 9.6 L/ha (gallon/acre) are discussed.
