Bacterial pesticides are biological pesticides with high insecticidal rates, do not pollute the environment, do not poison humans and animals, and do not induce pest resistance. However, the insecticidal effect of bacterial pesticides is related to the number and activity of bacteria, and the weather conditions are very strict when used. To increase the effectiveness of bacterial biopesticides, the following issues must be observed when using them. Temperature conditions: The suitable temperature for the spraying of bacterial biopesticides is 20-30°C, because the active ingredients of these pesticides are protein crystals and living spores. At low temperatures, spores propagate very slowly in insect pests, and protein crystals are less likely to act. Bacterial biopesticides are applied up and down at 25-30°C, and the efficacy is 1-2 times higher than at 10-15°C. Humidity conditions: the use of bacterial bio-agent pesticides, the higher the environmental humidity the higher the efficacy, especially pesticides with powdered biological agents. Because the bacterial spores are not resistant to the dry environmental conditions, it is advisable to spray the bacteria powder in the morning and evening when there is dew, in order to facilitate the bacterial agent to adhere well to the base leaf, and to promote the propagation of spores and improve the efficacy of the drug. Sunshine conditions: ultraviolet rays in the sun have a killing effect on spores, direct sunlight for 30 minutes, the spores mortality rate of about 50%, the mortality rate of up to 80% of one hour irradiation. In addition, ultraviolet radiation has a deformation and degrading effect on parasporal crystals. Therefore, it is best to apply biopesticides after 5 pm or on cloudy days. Rainwater conditions: Medium to heavy rain flushes the bacterial liquid sprayed on the leaves, reducing the efficacy, but if light rain is applied after 5 hours, it will not only reduce the control effect, but also have a synergistic effect.
