Abstract

The invention relates to an insecticidal composition which is prepared by compounding pyridine used as a first active ingredient with a second active ingredient selected from the group consisting of avermectin, emamectin benzoate, spinosad and spinetoram, wherein a weight ratio of the first active ingredient to the second active ingredient is 1: 20 to 20: 1, and the sum of the weights of the firstactive ingredient and the second active ingredient accounts for 1% to 60% of the total weight of the composition. A compound pesticide preparation of the insecticidal composition has significant synergistic effect and a co-toxicity coefficient of more than 135, presents an effective rate of 90% or more when applied to prevention and treatment of rice hoppers, makes up for the deficiency of single-agent pesticides, delays occurrence of pymetrozine resistance in pests, enhances drug effect, and is broadened in a prevention and treatment spectrum and reduced in dosage per mu, pesticide production cost and environmental pollution; and the compound pesticide preparation can be used for controlling agricultural pests attacking vegetables, rice, cotton, fruit trees and various crops.

Description

technical field [0001] The invention relates to an insecticide composition, in particular to pymetrozine and a biogenic insecticide selected from abamectin, emamectin benzoate, spinosyn or spinetoram The insecticide is an insecticidal combination of two effective active ingredients, and belongs to the technical field of pesticides. Background technique [0002] Selenium is an essential trace element for the human body. Selenium participates in the synthesis of various selenium-containing enzymes and selenoproteins in the human body. Selenium can improve human immunity, promote the proliferation of lymphocytes and the synthesis of antibodies and immunoglobulins. Selenium has obvious inhibitory and protective effects on colon cancer, skin cancer, liver cancer, breast cancer and other cancers, and its intermediate metabolite methyl enol in the body has strong anticancer activity. Selenium, vitamin E, allicin, linoleic acid, germanium, zinc and other nutrients have synergisti...
