Insecticide for preventing disease of fruit trees

Abstract

The invention discloses an insecticide for preventing disease of fruit trees. The insecticide is prepared from the following raw materials: 10 to 18 parts of tobacco leaves, 15 to 20 parts of garlic,8 to 15 parts of castor leaves, 12 to 18 parts of radix sophorae flavescentis, 6 to 15 parts of Chinese prickly ash, 5 to 8 parts of polyisobutene, 30 to 40 parts of an ultraviolet absorbent, 1 to 5 parts of carbon powder, and 11 to 17 parts of hexane. The insecticide has high contact toxicity to aphid, red spiders and ants, also has a suffocating and stomach poisoning effect, and can prevent thegrub; main raw materials are natural plants, so that the insecticide is nontoxic to the human body, and environment-friendly, and has the advantages of simple processing, low processing cost, low rawmaterial acquisition cost, and wide popularization range; and by mixing the polyisobutene, ultraviolet absorbent, carbon powder, hexane and a mixed solution of a tobacco solution, a garlic solution, castor beans powder, radix sophorae flavescentis and Chinese prickly ash, the drug effect can be prevented from being influenced by the direct illumination of the sunlight ultraviolet, the agglomeration of the medicine can also be avoided, the diffusion is avoided, and the medicine effect is not influenced; the insecticide is sprayed onto tree leaves, so that the alternaria leaf spots, rust diseases and fire blight can be effectively prevented; and when the insecticide is buried at the roots, the black rot and root cancer can be prevented.

Description

technical field [0001] The invention relates to the technical field of fruit tree disease prevention, in particular to an insecticide for fruit tree disease prevention. Background technique [0002] Fruit trees refer to trees with edible fruits, the general term for perennial plants and their rootstocks that can provide edible fruits and seeds. [0003] In environmental plant pest control, the task of fruit tree pest control is even heavier, because not only must it have a good control effect on pests, but it must also meet the requirements of the environment. [0004] The so-called fruit tree diseases and insect pests mainly refer to the fact that during the production period of fruit trees, due to some factors, the whole fruit tree will be attacked by insect pests, which will cause diseases. The emergence of diseases and insect pests will not limit the normal growth of fruit trees, and will also have an impact on fruit quality. If the management of pests and diseases can...

AI Technical Summary

Problems solved by technology

If the management of diseases and insect pests cannot be strengthened and reasonably controlled, the environmental conditions of the entire planting area will be destroyed. At the same time, if it is not controlled, the damage will intensify, thus affecting the growth of more organisms

[0005] In the prior art, insecticides for fruit trees cannot exert their medicinal properties under the direct sunlight ultraviolet rays. At the same time, they are highly toxic and pose a danger of poisoning to the staff, and are also likely to cause pollution to the environment.
