Problems solved by technology

Another defect of the existing insecticidal pesticides is that the duration of the drug effect is relatively short after application, and if it encounters cloudy and rainy weather after application, the drug is easily washed away by the rain, resulting in reduced or even ineffective drug effect.

preparation example Construction

[0070] A fourth aspect of the present invention provides a method for preparing the insecticidal pesticide water-dispersible granule, comprising the following steps:

[0071] (1) Mix the insecticide and the auxiliary agent evenly, and pulverize to obtain the mixed material;

[0072] (2) Mix the mixed material with diatomite of specific structure, shake for 5-20 minutes, then stir for 20-40 minutes until the mixture is uniform, and obtain mother powder;

[0073] (3) Knead the mother powder, granulate, dry and sieve to obtain the product.

[0074] Since the diatomite with a specific structure used in the present invention has a zigzag honeycomb structure, in order to avoid the structure of the diatomite with a specific structure being destroyed, it is necessary to mix the auxiliary agent uniformly before adding the diatomite with a specific structure, and add the diatomite with a specific structure. Mechanical pulverization cannot be used after the specific structure of diatoma...

Embodiment 1

[0079] Example 1 provides an insecticidal and pesticide water-dispersible granule containing diatomaceous earth with a special structure, which comprises 80% of an insecticidal and pesticide composition, 15% of adjuvants, and 100% of fillers.

[0080] The insecticidal and pesticide composition is a combination of diatomite with a specific structure and thiodicarb, and the weight ratio is 100:1; the diatomite with a special structure has a zigzag honeycomb structure, purchased from the French Imerys company, brand Celite610 .

[0081] The auxiliary agent is a dispersant, a wetting agent, a binder and a disintegrating agent, and the weight ratio is 1:0.8:1:0.2; the dispersant is a polymer polycarboxylate and naphthalenesulfonate formaldehyde condensate, The weight ratio is 1:1; the polymer polycarboxylate was purchased from Beijing Guangyuan Yinong Chemical Co., Ltd., model GY-D06; the methylnaphthalenesulfonate formaldehyde condensate was purchased from Anyang Bicyclic Auxiliar...

Embodiment 2

[0087] The difference between Example 2 and Example 1 is that the insecticidal and pesticide composition is diatomaceous earth with a special structure and lufenuron, and the weight ratio is 100:1.

Abstract

The invention relates to the technical field of pesticides, and concretely relates to an insecticidal pesticide composition containing diatomite with a special structure, and an application thereof. The insecticidal pesticide composition containing the diatomite with the special structure is prepared from diatomite with the special structure and an insecticide in a weight ratio of 1:(0.00-100), and the diatomite with the special structure has a zigzag honeycomb structure. The invention further provides an insecticidal pesticide water dispersible granule containing the diatomite with the special structure. 100% of the insecticidal pesticide water dispersible granule is prepared from, by weight, 65-85% of the insecticidal pesticide composition, 10-20% of an auxiliary agent, and the balance of a filler. Through compounding of the diatomite with the zigzag honeycomb structure and the chemical insecticide, liriomyza sativae, prodenia litura, tea geometrid, frankliniella occidentalis and scirtotuthrips dorsalis can be effectively prevented and controlled, the use amount of the chemical insecticide is reduced, and pesticide resistance cannot be generated.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to an insecticidal and pesticide composition containing diatomite with a special structure and its application. Background technique [0002] Chemical pesticides are an effective means of controlling pests and diseases. Especially in the epidemic of diseases and pest outbreaks, it is an effective control measure. Due to the long-term abuse of chemical pesticides, the resistance of pests has increased, and the cost of pest control has increased. So far, various pests have developed resistance to many organochlorine, organophosphate, organonitrogen, carbamate and pyrethrin pesticides. Generally speaking, after many pesticides are used for a period of time (3-5 years), due to the increase of pest resistance, the control effect will decrease until they are ineffective. People's resistance to pests is often the wrong way to increase the concentration and frequency of pesticide use....
