Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a preparation method of a biopesticide for lettuce Background technique [0002] The main pests of lettuce are mainly Tetranychus urticae and aphids. Tetranychus urticae mainly cluster on the back of the leaves of the host, and a few suck juice on the front of the leaves. In severe cases, the leaves dry up and fall off, and even cause the plant to die. When the population density is very high, a large number of insect bodies gather at the top of the leaves and shoots, forming light pink balls, the big ones are like peanuts. At this time, the plants are often nearly dry and dead. Due to the high drug resistance of Tetranychus urticae, it should be prevented and controlled in the early stage of occurrence. In order to improve the control effect, synergists or washing powder can be mixed in the liquid medicine, and the spraying method can be used. spraying. At present, chemic...
