Problems solved by technology

The control of cotton aphids mainly depends on chemical control. With the widespread use of insecticides, cotton aphids gradually develop resistance. Due to the large occurrence of cotton aphids and unreasonable use of field medications, their resistance develops rapidly and is difficult to control.
Moreover, the existing pesticides are only aimed at killing the cotton aphid, and the honeydew excreted by it still exists on the branches and leaves of the crops, causing the growth of mold, etc., and affecting the photosynthesis of the crops. become smaller and less, affecting its output

Abstract

The invention relates to a pesticide combination for prevention and treatment of aphis gossypii glover and a preparation method thereof, and belongs to the technical field of pesticide. The pesticide combination comprises a spraying agent and a root-irrigation agent which are combined for use. The spraying agent is prepared from aloes, ailanthus altissima leaves, safflower, quisqualis indica, dichroa febrifuga lour and sucrose fatty acid ester. The root-irrigation agent is prepared from diethyl aminoethyl hexanoate, garlic oil, KH2PO4, glucoheptonic acid, phosphatidyl ethanolamine, polyethylene glycol 200 and herb residues obtained after the spraying agent is extracted. According to the pesticide combination, a Chinese traditional medicine extracting solution is used for killing the aphis gossypii glover with poison, the prevention and control effect is good, environmental friendliness is achieved, low toxicity is achieved, the quantity of residues is small, pesticide resistance of the aphis gossypii glover is not prone to be achieved, and thus the pesticide combination is ideal green pesticide; the spraying agent is combined with the root-irrigation agent for use, nutrients needed by crops can be supplemented while the aphis gossypii glover is killed with poison, growth and development of the crops are promoted, and hence the yield is increased; the spraying agent can dissolve honeydew defecated by the aphis gossypii glover, mold breeding is reduced, the influence on the crops by the aphis gossypii glover is eliminated completely, and the growth vigor of the crops is recovered.

Description

technical field [0001] The invention relates to a medicinal composition for controlling cotton aphids and a preparation method thereof, belonging to the technical field of pesticides. Background technique [0002] Cotton aphid (Aphis gossypii Glover) is a worldwide omnivorous pest. The cotton aphid inserts the back of the leaf or the tender head to suck the branches and leaves with its piercing and sucking mouthparts, and there is honeydew excreted by the cotton aphid on the leaf surface. The honeydew is greasy and has high sugar content, which is easy to breed mold and can attract other smaller individuals Ants and other pests eat crops. The control of cotton aphids mainly depends on chemical control. With the widespread use of insecticides, cotton aphids gradually develop resistance. Due to the large occurrence of cotton aphids and unreasonable field application, the resistance develops rapidly and is difficult to control. Moreover, the existing pesticides are only aimed...
