Granula containing clothianidin

Abstract

Granula containing clothianidin comprises, by weight, 0.01%-10% of one of bifenthrin, cyfluthrin or tefluthrin, 0.01%-15% of clothianidin, 0.1%-40% of humic acid, 1%-15% of auxiliaries, 1%-10% of binder and the balance carriers. The granula containing the clothianidin is used for preventing and controlling soil insects, nematode and pests on the ground of crops such as sugarcanes, peanuts, corns and bananas, and is obvious in synergistic effect, good in prevention and control effect and long in a validity period. The granula can obviously improve a preventing and control effect of the crops on root knot nematode and pathogenic bacteria, simultaneously promotes development of crop root stocks and growth of plants, and improves yield and quality of the crops.

Description

technical field

[0001] The invention relates to the field of pesticide preparations, in particular to clothianidin-containing granules. Background technique

[0002] At present, granules are commonly used in domestic agricultural control of subterranean pests, and the active ingredients are mainly highly toxic carbofuran, terbufos, phorate, isofenphos-methyl, methimenphos, etc. The use of these agents has the following Three issues:

[0003] 1. It is very harmful to producers and users. Due to the high toxicity of these ingredients, a large number of poisoning accidents due to the production and use of these highly toxic agents occur every year, seriously threatening the lives and health of producers and users.

[0004] 2. The long residue period leads to excessive pesticide residues in agricultural products, which seriously affects the quality and price of agricultural products. It has become a major obstacle to the production of pollution-free agricultural products in my ...
