The results showed that, at a relative humidity （RH） of 90%, the protection and control efficiency of the preparation of B. subtilis B36 WP was 82.9% and 61.63%, respectively; at RH 100%, 32.84% and 31.63% ; at RH 90% and 30 ℃ or 20 ℃, 82.48% and 63.01%. It was shown that humidity and temperature had a greater impact on the efficacy of B. subtilis B36 WP to Botrytis cinerea.
