Do not use inferior chemicals to ensure the quality of the drugs used, should be purchased from regular manufacturers and drug sales points, in order to prevent the purchase of counterfeit and inferior drugs, and pay attention to the date of manufacture and the age of the drug.
Do not use bacterial insecticides at low temperatures. The active ingredients are protein crystals and living buds. Under low temperature conditions, spores are slow to propagate in pests, and protein crystals are not easy to function.
Do not use the bacterial spores in the bacterial environment in a dry environment. Therefore, the higher the humidity, the higher the efficacy, especially the spraying of powdered biological pesticides should pay attention to the humidity inside the shed. It is usually sprayed when there is dew in the morning and evening, so that the microbial agent can adhere to the stems and leaves of the crop better, and promote spore reproduction and improve the efficacy. It is better to spray the vegetables half an hour before spraying or spraying in the foggy morning.
Do not use the ultraviolet rays in the sun to kill the spores under strong light conditions. If the light is strong, the ultraviolet rays will kill the bacteria. In addition, ultraviolet radiation can degrade the parasitic crystals. Therefore, spraying bacterial insecticide should be carried out on cloudy or weak light into the vegetable field. It is usually applied before 10 am or in the evening on a sunny day.
Do not spray large sprays of bacteria after spraying large amounts of water. Otherwise, the bacteria will be washed away and the effect will be reduced. However, if it is sprayed after 5 hours of application, it will not reduce the control effect, and it can also be synergistic, because it is beneficial to the rapid propagation of bacterial spores.
Do not mix with fungicides. Do not mix with fungicides (carbendazim, methyl thiophanate, etc.) when applying bacterial insecticides. Otherwise, it will easily lead to a serious reduction in the number of bacteria in the drug, thus affecting the insecticidal effect. Therefore, even a sprayer that has been sprayed with a biocide should be rinsed to assemble a bacterial insecticide.
