Abstract

The invention discloses an insecticidal composition containing metarhizium anisopliae and cyromazine and a preparation method and application of the insecticidal composition.According to the insecticidal composition, metarhizium anisopliae and cyromazine serve as basic active ingredients, and metarhizium anisopliae conidia (piece) and cyromazine (gram) are mixed according to the ratio of (49-1) *2 *1010:(1-49).Wet powder, water dispersible granules and an oil suspending agent can be prepared after auxiliary materials are added to the active ingredients.The insecticidal composition can be used for preventing and treating pests such as scale insects, trialeurodes vaporariorum, thrips, grubs, wireworms, citrus fruit flies, liriomyza sativae, root maggots and Bradysia odoriphaga Yang et Zhang, is especially suitable for preventing and treating diptera pests such as citrus fruit flies, liriomyza sativae, root maggots and bradysia odoriphaga, and has the advantages of being stable in pesticide effect, good in fast-acting property, long in lasting period, safe, environmentally friendly and the like.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to an insecticide composition containing Metarhizium anisopliae and cyromazine, a preparation method and application thereof. Background technique [0002] Metarhizium anisopliae (Metarhizium anisopliae) is a broad-spectrum entomopathogenic fungus, which has the characteristics of a large distribution range and a broad parasitic spectrum. It is non-toxic to humans, animals and crops, and can parasitize a variety of insects. One of the most common entomophagous fungi. According to incomplete statistics, more than 200 species of insects such as Diptera, Lepidoptera, Coleoptera, and Homoptera around the world can be infected and killed by this fungus. Metarhizium anisopliae has significant insecticidal effect, and has a new mechanism of action different from existing insecticides, mainly acting on the hemolymph immune system of insects, causing them to lose their immune...
