Problems solved by technology

[0004] The purpose of the present invention is to provide a wettable powder based on imidacloprid and its preparation process, which can solve the problem that the existing wettable powder of imidacloprid has a single type of insecticide, which can only kill piercing and sucking mouthparts pests, and other types of pests are difficult to kill. Elimination, and the duration of the drug effect is short, and the drug cannot be released for a long time to kill insects

Embodiment Construction

[0038] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0039] see Figure 1-8 As shown, a wettable powder based on imidacloprid is made of the following materials in parts by weight: 10-90 parts of imidacloprid, 1-5 parts of powder, 3-15 parts of adsorbent, 15-20 parts of solid sodium hypochlorite, silicon 10-25 parts of algae earth;

[0040] Among them, the adsorbent is made by the following methods:

[0041] S1: Select a dry and porous activated carbon block, put it into the pulverizer, and pulverize it for 3 minutes at a speed of 1000r / min. After pulverization, use a 200-mes...

Abstract

The invention discloses an imidacloprid-based wettable powder which is prepared from the following materials in parts by weight: 10 to 90 parts of imidacloprid, 1 to 5 parts of nekal, 3 to 15 parts ofan adsorbent, 15 to 20 parts of solid sodium hypochlorite and 10 to 25 parts of diatomaceous earth. The adsorbent is mixed in the powder, so that the specific surface area of the powder is increased,the adsorption capacity of the powder is improved, and the absorption of internal insecticides is enhanced. The storage capacity of the insecticides is increased. The adsorbent is internally porous,and the insecticides are stored therein. After the wettable powder is sprayed onto the outside of crop, the adsorbent is adhered to the foliage of the crop and stays longer. The insecticides can be dispensed for a long time to kill insects, thereby improving the capacity of the insecticides to kill insects. The modified SiO2 is used to increase the hydrophilic ability of the wettable powder, so that the mixed spraying of the wettable powder and water is facilitated.

Description

technical field [0001] The invention relates to a wettable powder, in particular to an imidacloprid-based wettable powder and a preparation process thereof, belonging to the field of processing and application of the imidacloprid wettable powder. Background technique [0002] Imidacloprid is a super-efficient neonicotinoid insecticide with broad-spectrum, high efficiency, low toxicity, and low residue. It is not easy for pests to develop resistance, and it is safe for humans, animals, plants, and natural enemies. It also has contact, stomach, and systemic toxicity. and other multiple functions. After the pests are exposed to the pesticide, the normal conduction of the central nervous system is blocked, causing them to paralyze and die. It is mainly used to control pests with piercing and sucking mouthparts. [0003] But the wettable powder of existing imidacloprid still has certain deficiency in use. The existing wettable powder of imidacloprid has a single type of insecti...
