Problems solved by technology

Field production generally adopts chemical control methods, which have quick results, but there are problems of pesticide residues
[0003] At the same time, it will affect the food safety and taste of wheat
In addition, long-term application of pesticides will also make wheat aphids resistant to pesticides, resulting in a decline in control efficiency and making future control more difficult.

Abstract

The invention relates to the technical field of botanical insecticide and discloses a composition for preventing and treating wheat aphids and a preparation method and application of the composition. The composition is prepared from monstera deliciosa, bojers spurge, Euphhorbia jolkini boiss, Lycoris aurea Herb and schefflera octophylla. By selecting the natural plants monstera deliciosa, bojers spurge, Euphhorbia jolkini boiss, Lycoris aurea Herb and schefflera octophylla for digestion, the plant composition containing five plant active ingredients is obtained, the composition can effectively prevent and treat the wheat aphids, and compared with pesticide containing chemical ingredients, the composition does not affect the yield and taste of crops, and is free of pollution, safe and free of residues.

Description

technical field [0001] The invention relates to the technical field of plant insecticides, in particular to a composition for preventing and treating wheat aphids, a preparation method and application thereof. Background technique [0002] Wheat aphid, one of the main pests of wheat, affects wheat photosynthesis and nutrient absorption and conduction. It overwinters in the wheat and rice piles, and the nymphs and adults cluster to suck the juice of wheat leaves, stems and spikes. The peak period of wheat aphid damage is from the earing to the grain filling stage of wheat. During the earing period, wheat aphids concentrate on the wheat ears to suck, which makes the wheat grains empty and the wheat yield decreases. Field production generally adopts chemical control methods, which have quick results, but there are problems of pesticide residues. [0003] At the same time, it affects the food safety and mouthfeel of wheat. In addition, long-term application of pesticides will...
