Abstract

The invention discloses a method for preparing a botanical pesticide for preventing and treating rice planthoppers, and the method for preparing the botanical pesticide for preventing and treating rice planthoppers comprises the following steps: uniformly mixing trehalose, chitosan and the balance of traditional Chinese medicine components to prepare an active mixed culture medium containing traditional Chinese medicines; inoculating an active mixed culture medium containing traditional Chinese medicines with a compound microorganism strain for fermentation culture to obtain the botanical pesticide for preventing and treating rice planthoppers. An effective mite killing effect can be achieved by adopting aralia delavayi, radix euphorbiae lantu, fructus kochiae, radix pulsatillae, radix sophorae flavescentis, radix veratri, xanthium sibiricum, fructus cnidii and flos caryophylli; meanwhile, sodium alginate and chitosan can improve the activity of compound microorganisms, and the microorganisms are natural kills of the rice planthoppers, so that the synergistic use of the traditional Chinese medicines and the microorganisms can realize pollution-free effective control of the rice planthoppers.

Description

technical field [0001] The invention relates to the field of insecticides, in particular to a method for controlling plant-derived pesticides for rice planthoppers. Background technique [0002] In recent years, the pollution of pesticides has gradually attracted great attention from all over the world, and low-toxicity and low-residue pesticides have become the focus of research. Biopesticides can directly use natural biological substances and the interaction between organisms to control pests and weeds or improve ecology, so biopesticides are internationally recognized as the most promising pesticides. However, in the prior art, there are fewer types of biopesticides, and there is no biopesticide capable of controlling rice planthoppers. Chemical pesticides have played an important role in the prevention and control of forestry pests. However, the environmental pollution and crop damage caused by them are immeasurable. If the biological agents are properly used for preve...
