Abstract

Field research since 1978 using different formulations, dosages, and spray volumes of Bacillus thuringiensis Berliner (Bt) against the gypsy moth are reviewed. Problems associated with inconsistent results are discussed, with an emphasis on timing of application. Recommendations for proper use of Bt are presented along with suggestions for further studies on the use of Gypchek and development of better spray technology for both Bt and Gypchek.
