Soluble granule for preventing and treating root disease and application method thereof

Abstract

The invention discloses a soluble granule for preventing and treating a root disease and an application method, and belongs to the field of pesticides. The soluble granule is prepared from a carrier and missible oil, wherein components of the carrier comprise a soluble salt, citric acid, ammonium hydrogen carbonate, polyvinylpyrrolidone and a pigment; components of the missible oil comprise two compounded active ingredients, dimethyl formamide, epoxidized soybean oil, butylated hydroxytoluene and nonylphenol polyoxyethylene ether. A preparation method of the carrier of the soluble granule comprises the following steps of stirring and dissolving raw materials of the carrier at a high temperature, and cooling and crushing to obtain the carrier; A preparation method of the missible oil comprises the following steps of adding raw materials of the missible oil according to a sequence, and stirring and dissolving to form the missible oil. A preparation method of the soluble granule comprises the following steps of mixing the missible oil with the carrier, and discharging and sieving a material, so as to make a finished product. The application method of the soluble granule comprises broadcast application, covering sowing, hole sowing and irrigation application. The soluble granule has advantages of being high in agent adsorption capacity, quick in dissolution rate, low in toxicity, low in cost, good in prevention and treatment effects, simple in preparation method and multiple in the application method, and the like.

Description

technical field [0001] The invention relates to a pesticide composition and an application method, in particular to a soluble granule, which belongs to a compound pesticide and is used for preventing and controlling underground pests and root diseases in field crops, fruit trees, vegetables, other special crops and turf. Background technique [0002] Plant root diseases have serious harm to plant growth, resulting in short, slow growth, abnormal leaf color, few fruits, and even premature death of the damaged plants, causing a large amount of economic losses every year. At present, most of the pesticides used to prevent and control root diseases are contact type, and the systemic type is less. Systemic effect. [0003] Root diseases occur in the underground parts of plants, and it is not convenient to spray pesticides. A large amount of liquid pesticides is likely to cause soil pollution. The waste of pesticides and input costs are relatively high, and the active ingredients...

AI Technical Summary

Problems solved by technology

Soluble pesticides, such as wettable powder or emulsion, need to be dissolved in water before watering or spraying, and cannot be used for planting, hole planting or spreading.

[0007] Among the pesticides currently used to prevent and control plant root diseases, most of the pesticides that contain two or more active ingredients and are completely soluble in water are in the form of emulsifiable concentrates, and the carriers of compound granules are not completely soluble in water and can only be used for planting. , and the pesticide dosage form with fully soluble carrier only contains a single active ingredient, which is not ideal for the treatment of plant root diseases

[0008] Existing granules also generally have the problem of not being strong in absorbing liquid, or easy to get damp after absorbing water, and stick to each other, so it needs to be ventilated and dried

However, it is easy to cause the active ingredients to be decomposed and oxidized in the sun for a long time, and the insecticidal activity is reduced or even invalid.
