Problems solved by technology

[0004] Although both have good insecticidal effects, they cannot provide nutrition for crops, and the existing products use the two alone or in combination, and use them separately from fertilizers. Users need to apply fertilizers and pesticides separately when using them. , and because the existing products do not have a sustained-release effect, multiple applications are required, which is time-consuming and laborious

Abstract

The invention relates to a sustained-release pesticide fertilizer and a preparation method thereof, belonging to multifunctional sustained-release pesticide fertilizers combining pesticides and fertilizers. The sustained-release pesticide fertilizer is prepared from the following main components: chlorfluazuron, imidacloprid, fertilizers, humic acid, an auxiliary agent, a slow-release agent and filler; the sustained-release pesticide fertilizer is a pesticide fertilizer product which has a sustained release effect and is prepared by performing the processes of crushing, mixing, extruding, granulating, film coating and the like on the components. The sustained-release pesticide fertilizer has double effects of killing pests and strengthening seedlings, and has an obvious synergistic effect; the sustained-release pesticide fertilizer is complete in nutrition, eases continuous cropping, is simple and convenient to operate, labor-saving and cost-saving, and can enhance the vitality of crops and improve the quality of the crops while controlling pest damage.

Description

technical field [0001] The invention relates to the technical field of medicinal-fertilizer mixture, in particular to an insecticidal slow-release medicinal fertilizer and a preparation method thereof. Background technique [0002] Chlorfluazuron is a low-toxicity insecticide with high stomach toxicity and contact action. It has extremely high activity against pests such as Lepidoptera, Coleoptera, Hymenoptera, and Diptera. At present, there are relatively few development registrations for chlorfluazuron , Maggots are a kind of pests that occur in leeks, garlic, lettuce, flowers, Chinese herbal medicines and other crops all year round, with a large area and serious damage. They reproduce quickly and have a short growth cycle. In high temperature areas, 8-9 generations can occur a year, and the generations overlap. serious. Its types mainly include leek maggots, garlic maggots, and ground maggots. They eat the roots of crops in the soil. After feeding, the roots will rot, an...
