Novel wheat pesticide and preparation method thereof

Abstract

The invention discloses a novel wheat pesticide and a preparation method thereof. The novel wheat pesticide comprises the following components in parts by weight: 70-90 parts of herba artemisiae capillariae, 30-40 parts of achnatherum inebrians, 30-50 parts of flos caryophyllata, 50-70 parts of stem of oriental bittersweet, 10-20 parts of Chinese honey locust powder, 10-20 parts of herba agrimoniae, 15-40 parts of herba polygoni salicifolii, 20-40 parts of Chinese tallow leaves, 10-30 parts of tuberculate speranskia herb and 10-20 parts of herba andrographitis. The novel wheat pesticide is prepared from the above components through four steps of raw material treatment, soaking in warm water, boiling and cooling and purification with ethanol. As the pure plants are adopted as raw materials, the novel wheat pesticide is green and pollution-free, has no chemical residues, causes no harm to the environment and no injury to people, and can effectively prevent and control diseases and pests of wheat, the economic profit is increased and the production cost is lowered.

Description

technical field [0001] The invention belongs to the field of wheat insecticides, and in particular relates to a novel wheat insecticide and a preparation method thereof. Background technique [0002] Wheat is the second largest food crop in the world, after corn, and rice is the third. The world production and planting area of ​​wheat rank first among the cultivated grains, and common wheat is the most widely planted, accounting for more than 90% of the total wheat area in the world, and the sown area of ​​durum wheat is about 6% to 7% of the total area. [0003] Wheat is one of the main grains in our country. It contains starch, protein, sugar, fat, vitamin B, lecithin, arginine and various enzymes. Not only has extremely high nutritional value, but also wheat seedlings, malt, wheat bran, and wheat seeds can be used as medicine. As early as 1700 years ago, Zhang Zhongjing, a Chinese medical sage, created the famous prescription "Licorice, Wheat and Jujube Decoction", whic...

AI Technical Summary

Problems solved by technology

Growers have used traditional insecticides for a long time, which has caused pests to develop resistance, and the insecticidal effect is not significant. After repeated insecticides, it increases the cost input

[0005] With the improvement of people's living standards, higher requirements are put forward for the safety, quality and environmental protection of food, and the demand for green food is increasing day by day. Barriers, the weather is getting warmer, and there are far more mosquitoes than we imagined. Ordinary pesticides have a strong smell and pungent smell. There are pesticides left on the wheat. If they fall into the soil, they will destroy the soil structure and cause damage to the soil, which will reduce the wheat harvest next year and damage the soil. The nutrients in the soil will cause a certain amount of harm to the body after people inhale the smell of pesticides
