Plutella xylostella appears all the year round, and bacterial insecticides are skillfully used to control Plutella xylostella. The control effect of bacterial insecticides is better for Lepidoptera pests such as Plutella xylostella. There are many kinds of bacterial insecticides, and the first high-efficiency Bt in China is Bacillus thuringiensis. The commonly used dosage is 8000 international units / ml per mu, diluted by 500 to 1000 times the spray. In the application of bacterial fungicides, technical attention should be paid to several points: the dosage should not be too high or too low, focusing on the control of young larvae, especially the 1st and 2nd instar larvae; avoid high temperature, preferably in sunny afternoon or cloudy days, and should not be applied when the temperature is lower than 15 ℃; spraying should be applied on the back of vegetable leaves.
