Abstract

The invention belongs to the field of pesticides, and relates to an imidacloprid fully-soluble granule. The granule are prepared from 1-5% of imidacloprid, 5-25% of an adhesive, 5-25% of a disintegrating agent, 2-10% of an auxiliary material, 1-3% of a solubilizer, 1-10% of a dispersing agent, 2-5% of a wetting agent, 15-35% of soluble starch and 3-5% of gelatin. A preparation method of the imidacloprid fully-soluble granule comprises the following step: wrapping and bonding imidacloprid which is difficult to dissolve and is difficult to dissolve in water by combining a hydrophilic adhesive . According to the invention, through process and formula improvement, imidacloprid which is difficult to dissolve in water is prepared into the fully-soluble granule product, and drug components can be quickly and efficiently absorbed by plants, so that the problems that after drug application, the drug is scoured in raining or coniferous tree species cannot absorb the drug and the like are solved.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to pesticides, in particular to a fully soluble granule formulation of imidacloprid and clothianidin. Background technique [0002] Traditional garden pest control, such as tree pest control in parks and urban green roads, needs to be sprayed regularly during the peak period of insect pests from mid-April to mid-September in the north and from March to November in the south, sometimes for a month. To spray 3-4 times the agent. However, it is more difficult to spray chemicals for tall trees. The spraying equipment can only be sprayed to a height of 5-10 meters, and it is difficult to spray for many trees over 10 meters. In high temperature weather, the insect pests are serious, and the spraying agents are scattered, causing harm to the spraying personnel. Since the chemical is sprayed on the tree body or leaves, there are several problems: 1. In high temperature weather, the stomata of th...
