Pesticide for orange

Abstract

The invention discloses a pesticide for orange. The pesticide is prepared from the following components in parts by weight: 40-60 parts of pinellia tuber, 20-40 parts of honeysuckle flower, 10-20 parts of phellodendron bark, 5-15 parts of pokeweed, 10-20 parts of rhizoma acori graminei, 5-15 parts of safflower and 3-12 parts of eucommia. The pesticide has quick effect, difficult decomposition of active components and lasting effect, and reduces the consumption of pesticide and frequency of use of the pesticide; the pesticide formula is simple and easy for standardization and industrialized popularization and use; the pesticide has wide sources of raw materials, low cost, no chemical pesticide components, no public nuisance and no residue, greatly reduces environmental disruption and also reduces poisoning to an applicator in the process of application; the pesticide has broad range of disinsection, low environmental pollution, strong selectivity and low toxicity to people, livestock and native predators; and pests are difficult to generate chemical resistance, and the pesticide is green, healthy, environment-friendly and efficient.

Description

technical field [0001] The present invention relates to plant insecticides, especially citrus insecticides. Background technique [0002] Citrus is one of the most important fruits in southern China. It has high edible value and considerable economic benefits. It is mainly cultivated in the provinces south of the Yangtze River. In recent years, due to the warming climate and the long phenological period of citrus, there are many kinds of citrus pests, and the damage is becoming more and more serious. The pests that cause large losses include spider mites, scale insects, and citrus leaf miners. Most of the insecticides in the prior art are chemical pesticides, which have low drug efficacy and a long period of residual toxicity, seriously affecting the crop growth environment and the health of humans and animals. Pesticides are a special class of chemicals, which can not only prevent and control agricultural and forestry diseases and insect pests, but also cause harm to human...

AI Technical Summary

Problems solved by technology

Highly effective and highly toxic pesticides are highly toxic and remain in the environment for a long time. When humans and animals eat food containing pesticide residues, they will cause cumulative poisoning

This type of hazard often takes a long time to accumulate before showing symptoms, and it enters the human body through the enrichment of the food chain, and it is difficult to detect in time. Therefore, it is generally not taken seriously by people, and this type of pollution has a wide range. , the number of people harmed is large, and in many cases, it is human beings who are poisoning themselves, so this kind of harm is more dangerous

Once pesticides enter the environment, their toxicity and high residue characteristics will have an effect, causing serious pollution of the atmosphere, water and soil, thereby causing harm to human health

When toxic pesticides are applied to crops, vegetables and fruit trees, the pesticides remaining on the surface of the crops, due to their strong fat solubility, can easily penetrate into the waxy layer of the crop epidermis, making it difficult to completely wash off
