The insecticide is prepared from mint, tea seed powder, ocimum gratissimum, eucalyptus leaves, rhizoma polygoni cuspidati and herba pogostemonis. All drugs cooperate to achieve a synergic effect, and a formula structure is strict; the apple tree insecticide is extremely outstanding in effect of preventing and treating insects in apple trees and is favorable for growth of apples. The insecticide does not contain any toxic chemical components or any residual toxins, is harmless to human bodies, the environment and water resources, and can replace the existing chemical insecticide.

Description

technical field

[0001] The invention relates to an insecticide and a preparation method thereof, in particular to an apple tree insecticide and a preparation method thereof. Background technique

[0002] At present, in my country, a large amount of chemical pesticides are widely used in the process of agricultural and forestry pest control, which have severe side effects, lead to serious pollution of land and water sources, and affect the safety of human and animal life. Chemical insecticides are expensive to produce and have a short duration of action. They stay on the surface of grains, vegetables, fruits, pastures, etc. for a long time and are difficult to decompose, causing serious harm to humans and animals, even life-threatening. In the process of spraying pesticides, operators often suffer from poisoning, and long-term use will cause serious pesticide resistance in pests. In order to ensure the insecticidal effect, the dosage of pesticides must be increased, and the r...
