Problems solved by technology

At present, in production, people often mix a large amount of soil fungicides such as pentachloronitrobenzene or dexazone into the soil, or use systemic fungicides for foliar spraying, but the effects are not ideal, so basically in production There are no effective prevention techniques

Embodiment 1

[0021] Weigh 3 parts of 80% carbendazim wettable powder, 2 parts of chlorfenadin original drug, add to 10 parts of attapulgite (particle size about 20-40 mesh), mix evenly, and set aside. Mix the above mother powder with 78.8 parts of sieved attapulgite (with a particle size of about 20-40 mesh) and add them to the coating granulator for stirring. While stirring, add 10% polyvinyl alcohol aqueous solution 3 1 part, 0.5 part of organic silicon synergist, 2 parts of calcium lignosulfonate, 0.5 part of triphenyl phosphate and 0.2 part of acid red B, mix well and discharge, then dry and sieve to get 100 parts of qualified products .

Embodiment 2

[0023] Weigh 4.8 parts of 50% carbendazim suspending agent and 2 parts of chlorpyridone original drug, add it to 20 parts of attapulgite (with a particle size of about 20-40 mesh), mix evenly, and set aside. Mix the above-mentioned mother powder with 55 parts of sieved attapulgite (with a particle size of about 20-40 mesh) and add them to the coating granulator for stirring. While stirring, add 8.2 parts of 10% starch aqueous solution, 2 parts of methyl synergist, 5 parts of fatty alcohol polyoxyethylene ether, 2 parts of phosphorous acid and 1 part of acid scarlet, mixed well and discharged, dried and sieved to obtain 100 parts of qualified products.

Embodiment 3

[0025] Weigh 3 parts of 80% carbendazim wettable powder and 2 parts of chlorfenadin original drug, add them to 4.7 parts of attapulgite (with a particle size of about 20-40 mesh) and mix evenly, and set aside. Mix the above-mentioned mother powder with 88 parts of sieved attapulgite (with a particle size of about 20-40 mesh) and add them to the coating granulator for stirring, and add 1 part of 10% dextrin solution gradually while stirring , 0.1 part of synergistic ether, 1 part of sodium dodecylbenzenesulfonate, 0.1 part of hydroxysulfonic acid and 0.1 part of pinnatine violet, mix well and discharge, dry and sieve to obtain 100 parts of qualified products.

Abstract

The invention discloses farm chemical granules. The farm chemical granules are prepared from, by weight, 3-4.8 parts of carbendazim, 2 parts of buprofezin, 0.1-2 parts of stabilizing agents, 0.1-2 parts of synergist, 1-5 parts of dispersant, 1-10 parts of agglomerant, 0.1-1 part of colouring agents and 73.2-92.7 parts of carriers. The invention further provides a preparation method of the farm chemical granules. The farm chemical granules and the preparation method thereof have the advantages that a concave-convex rod is adopted as a farm chemical carrier, low-toxicity and low-residue bactericide, namely the carbendazim and the buprofezin, is mixed with the agglomerant and auxiliary agents in proportion, the granules are prepared and obtained, the detect that common granules are short in persistent period is overcome, and certain fertilizer efficiency, soil improvement property and environmental protection property are further achieved. Granule farm chemical prepared through the method has the advantages of being great in target property, low in manufacturing cost, high in chemical adsorption rate and long in persistent period, and a good prevention and control effect is achieved on onion root rot and bacterial soft rot caused by fusarium oxysporum.

Description

technical field [0001] The invention relates to the field of pesticide production and preparation, in particular to a pesticide granule and a preparation method thereof. Background technique [0002] There are many kinds of soil-borne diseases of crops, which are mainly divided into fungal diseases and bacterial diseases from the large categories. For example, onion soil-borne diseases mainly include fungal onion stalk rot and onion bacterial soft rot. With the continuous planting of onions, these diseases have become more serious year by year, posing a serious threat to the development of the onion industry. At present, in production, people often mix a large amount of soil fungicides such as pentachloronitrobenzene or dexazone into the soil, or use systemic fungicides for foliar spraying, but the effects are not ideal, so basically in production There are no effective control techniques. Research on new pesticides for the prevention and control of soil-borne diseases is ...
