Abstract

The invention discloses a water dispersible granule with 25 percent of thiamethoxam. The water dispersible granule is prepared from the 25 percent of thiamethoxam, 6.2 to 6.4 percent of dispersant KZ-009, 2 to 4 percent of wetting agent KZ-016, 5.8 to 7.2 percent of lignin naphthalenesulfonate dispersant KZ-021, 71.3 to 74.6 percent of bioprotein KZ-088, 1 to 3 percent of stabilizer KZ-031, 1.5 to 3 percent of lactose and 3 to 6 percent of corn starch. According to the water dispersible granule, through adding the 71.3 to 74.6 percent of bioprotein KZ-088, a production environment for the thiamethoxam is recreated by utilizing the KZ-088; a biopesticide emamectin is enabled to be more stable under a new formula; various technical indexes of a product are enabled to be higher; the pharmacodynamic exertion is more facilitated; the water dispersible granule is more stable to light, safer to an environment, more environmentally friendly and more efficient.

Description

technical field [0001] The invention belongs to the technical field of natural sweeteners, in particular to a 25% thiamethoxam water-dispersible granule. Background technique [0002] Thiamethoxam (Methylamino Abamectin Benzoate for short) is a macrolide disaccharide compound obtained by semichemical synthesis from abamectin. Compared with abamectin, the toxicity of this compound is one-third, and the activity is increased by 10-1000 times. It has high efficiency, broad spectrum, low toxicity, no residue, and no cross-resistance with other insecticides. Advantages, it is considered to be an ideal substitute for highly toxic insecticides. At present, thiamethoxam insecticide has been widely used in developed countries. [0003] The mechanism of action of thiamethoxam on pests is to enhance the effect of neurotransmitters, so that a large amount of chloride ions enter nerve cells, causing them to lose their normal functions; the pests stop eating within a few hours, become p...
