Abstract

The invention discloses a stored grain pest insecticide. The insecticide comprises, by weight, 30-42 parts of vitex negundo linn, 30-42 parts of Chinese prickly ash, 20-30 parts of chenopodium ambrosioides, 22-30 parts of folium eucalypti, 1-4 parts of dispersing agent, 70-80 parts of carrier and 1-8 parts of adhesive. Various raw materials of the stored grain pest insecticide cooperate with each other, advantages are complementary, the corrected death rate of sitophilus zeamais, sitophilus zeamais motschusky, tribolium castaneum and bruchid is high, the insecticidal effect is remarkable, residues are not generated, and the insecticide is environmentally friendly, convenient to use and long in validity period.

Description

technical field [0001] The invention relates to the application of biological pesticides in the field of grain storage, in particular to an insecticide for storage pests and a preparation method thereof. Background technique [0002] Corn weevils, grain beetles, red corn beetles, rice weevils, and mung bean weevils are common storage pests. These pests are small in size, strong in reproduction, and very harmful. , Broken, hollow, also lead to food heating, mildew, and pest secretions, feces will also pollute the food, these conditions will not only lead to a large loss of food in the storage process, but also reduce the germination rate, damage agricultural production, and affect the human body health, resulting in serious economic losses. The mechanism of action of the commonly used pesticides for the prevention and control of storage pests is mainly based on fumigation, such as chemical pesticides such as ethylene oxide, phosphine, and potassium bromide. If the chemical p...
