Problems solved by technology

But at the same time, the environmental pollution caused by chemical pesticide residues is also becoming more and more serious. Chemical pesticides enter the human and animal bodies through the food chain and cause great harm.
Moreover, the structure of chemical pesticides is single, the residual time is long, and the resistance of pests is easy to form

Embodiment 1

[0017] Collect 1 part of Drunken Horse Grass, 1 part of Poison Quinoa, 2 parts of Aconitum Aconitum, 3 parts of Sophora Sophora, 1 part of Veratrum, and 2 parts of Tobacco, dry them, grind them into coarse powder, mix them, add water, and heat them at a temperature of 85°C Heat and extract under low temperature for 2 hours, filter and concentrate the extract to obtain the finished product. When in use, the concentrated finished product is diluted to 50 times with water and sprayed on the leaves of crops to kill insects.

Embodiment 2

[0019] Collect 4 parts of Drunken Horse Grass, 5 parts of Poison Quinoa, 5 parts of Aconitum Aconiti, 6 parts of Sophora Sophora, 4 parts of Veratrum, and 4 parts of Tobacco, and dry them in the air, grind them into coarse powder, mix them, add water, and heat them at a temperature of 90 °C Heat and extract under low temperature for 3 hours, filter and concentrate the extract to obtain the finished product. When in use, the concentrated finished product is diluted to 50 times with water and sprayed on the leaves of crops to kill insects.

Embodiment 3

[0021] Collect 7 parts of Drunken Horse Grass, 6 parts of Poison Quinoa, 9 parts of Aconitum, 9 parts of Sophora Sophora, 8 parts of Veratrum, and 9 parts of Tobacco, and dry them in the air, grind them into coarse powder, mix them, add water, and heat them at a temperature of 95°C. Heat and extract under low temperature for 4 hours, filter and concentrate the extract to obtain the finished product. When in use, the concentrated finished product is diluted to 50 times with water and sprayed on the leaves of crops to kill insects.

Abstract

The plant pesticide for crops consists of lindley butterflybush, toxic caltrop, wild aconite, foxtail-like sophora herb, black falsehellebore and tobacco. Large area field experiment of cotton, wheat, corn, fruits and vegetables shows that the pesticide has effective rate to cotton aphid, red spider, cotton leaf springtail, cabbage worm and other crop pests as high as 89-92%. Therefore, the said pesticide has obvious preventing and controlling effect on crop disease and insect injury and yield increasing effect.

Description

technical field [0001] The invention relates to a plant pesticide for crops Background technique [0002] At present, the insecticides used for crops are all chemical pesticides, and chemical pesticides have played a huge role in controlling pests and diseases and improving crop yields. But at the same time, the environmental pollution caused by chemical pesticide residues is also becoming more and more serious. Chemical pesticides enter the human and animal bodies through the food chain and cause great harm. Moreover, the structure of chemical pesticides is single, and the residual time is long, and the resistance of pests is easy to form. Existing studies have shown that cancer, cardiovascular and other diseases that seriously endanger human health are closely related to the excessive use of chemical pesticides. With the aggravation of environmental pollution, people pay more and more attention to the research work of plant pesticides. [0003] In o...
