Environmentally friendly microbial pesticide for killing acarid

Abstract

The invention discloses an environmentally friendly microbial pesticide for killing acarid, and the environmentally friendly microbial pesticide comprises the following components by weight: 1-3 parts of monoucleosis powder, 0.5-1.0 part of bacillus subtilis powder, 8-12 parts of herba ephedrae, 1-2.5 parts of raw ginger, 2.5-3.5 parts of erodium stephanianum willd, 20-35 parts of xanthium, 30-40 parts of pomegranate rind, 1-3 parts of mugwort leaf, 11-21 parts of cordate houttuynia, 9-16 parts of andrographis paniculata, 3-8 parts of hemp, 7-9 parts of serrate chloranthus, 9-13 parts of artemisia annua leaf, 2-5 parts of tobacco, 3-8 parts of radix phytolaccae, 7-12 parts of dandelion, 11-13 parts of leech, 8-13 parts of croton, 3-6 parts of polygonatum odoratum, 2-4 parts of nard, 1-3 parts of licorice and 3-9 parts of euphorbia kansui. The environmentally friendly microbial pesticide has characteristics of both a biological pesticide and a plant pesticide, if a synergist is added, the relationship of the pesticide efficacy and the components is geometrically progressed, the experimental data shows that the pesticide efficacy is 10-20 times of the efficacy of a single component, and the environmentally friendly microbial pesticide is low in toxicity to human and birds.

Description

technical field [0001] The invention relates to a green biological pesticide for preventing and controlling mites. Background technique [0002] At present, the widespread use of chemical pesticides has caused environmental pollution, and the residual pesticides are not only harmful to the health of humans and animals, but also cater to the soil and destroy the ecological balance. In recent years, new pollution-free and pollution-free insecticides have been continuously developed at home and abroad, and some new varieties of non-chemically synthesized pesticides have emerged. The currently widely used pesticide is an aqueous solution with a single component of matrine as the active ingredient. This pesticide is only effective against young armyworms and larvae, and is very poorly sensitive to 4-5 instars. It is basically ineffective against mites. limited. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an env...
