Problems solved by technology

However, the use of single, multiple, and large doses of pesticides inevitably leads to the emergence and growth of pest resistance
[0004] At present, more than 80% of the pesticides used in China are organic synthetic pesticides. The large-scale use of highly toxic and high-residual organic synthetic pesticides has caused serious negative effects such as pest resistance, environmental pollution, and mass killing of beneficial organisms.

Abstract

The invention discloses an insect-expelling and disinsection composition for organic rice. The insect-expelling and disinsection composition is prepared from the following raw materials in percentage by weight: 5%-10% of neochamaejasmin, 8%-12% of rumex nepalensis, 7%-13% of toosendan leaves, 3%-6% of abrus precatorius, 13%-16% of quisqualis indica, 18%-22% of radix stemonae and the balance being water. According to the insect-expelling and disinsection composition for the organic rice and the preparation method thereof, the prevention and removing effects on weeds of paddy fields are improved, the herbicide controlling spectrum is enlarged, and fresh weight control effects and comprehensive fresh weight control effects are improved, so that the safety of various rice crops in the fields is guaranteed.

Description

technical field [0001] The invention relates to the field of rice cultivation, in particular to an organic rice insect repelling composition and a preparation method thereof. Background technique [0002] Paddy crops in my country are mainly rice, while dryland crops mainly include vegetables, wheat, cotton, and corn. These crops will be attacked by pests such as pests and weeds to varying degrees during their growth process. In order to ensure the yield and quality of crops, it is inevitable to use pesticides. Rice pests in my country mainly include: brown planthopper, brown planthopper, white-backed planthopper, rice stem borer, rice stem borer, rice leaf roller, etc. Cruciferous vegetable pests in my country mainly include: diamondback moth, cabbage caterpillar, spodoptera litura, beet armyworm, cabbage aphid, etc. Pests on wheat mainly include wheat aphids, midges, and mites. [0003] For a long time, people have mainly relied on chemical pesticides to control these c...
