Abstract

The invention discloses a compound preparation for preventing and controlling rice pests based on illicium verum leach liquor and a preparation method thereof, in particular to the field of botanicalinsecticides. The preparation comprises the following components in parts by weight: 20-40 parts of illicium verum leach liquor, 10-20 parts of hovenia dulcis thunb aqueous extract, 5-15 parts of lvsong fruit aqueous extract, 7-12 parts of brassica campestris aqueous extract and 1-5 parts of buddleia. The preparation can play a role in repelling and contact-killing main injurious insects, namely rice planthoppers, in the growth process of rice. The preparation adopts a plant source formula so that the self-safety of an eater cannot be influenced by drug residues after the eater eats the preparation.

Description

technical field [0001] The invention relates to the field of botanical insecticides, in particular to a compound preparation for controlling rice pests based on star anise extract and a preparation method thereof. Background technique [0002] Botanical insecticides have a unique mode of action and a high degree of environmental harmony, which can prevent or delay pest resistance. At present, it has become a research and development hot spot for new insecticides at home and abroad, and has extremely broad development prospects. In the process of rice production, rice planthopper (white-backed planthopper, brown planthopper, etc.) is one of the main pests in Asian rice regions. Its reproductive ability and ability to spread viruses are strong, causing great damage to rice production and also spreading rice black streaks. The main vector of viral diseases such as dwarfism. At present, the main medicaments on the market for controlling rice planthoppers are chemical insecticid...
