Abstract

The invention relates to a large composition floating granule for preventing and controlling sheath blight and rice blast of rice, and a preparation method thereof. The large composition floating granule comprises an effective component A, an effective component B, a water surface expansion agent, a disintegrating agent, a dispersant, a wetting agent, a core material with the density being smaller than that of water, an oily substance and a filler; and the effective component A is used for killing sheath blight pathogens, and the effective component B is used for killing rice blast pathogens. The structure of the large granule makes the applied medicine granule rapidly disintegrate in a radial manner and randomly float and expand to all directions, so the large granule can be uniformly dispersed in the whole water surface to form a medicine film in order to make the whole water layer become a medicine suspension, thereby the large granule has lasting and uniform effects, has no medicine harms to crops, and can effectively kill pathogens. Compared with traditional field pesticide sprinkling modes, the large granule is applied only through pouring the large granule to a water field nearby the field without going to the field, so the labor and the time are saved. 300 Billion m<2> of rice field exists in China, and the large granule saves huge manpower cost, and has a high applying efficiency and good effects.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a composition floating granule for preventing and treating rice sheath blight and rice blast and a preparation method thereof. Background technique [0002] China is a big rice country, with a planting area of ​​450 million mu, ranking second in the world, and a total output of 200 million tons ranking first in the world. Rice sheath blight and rice blast are the main diseases that affect rice production in my country. When pests and diseases occur, rice production can be reduced by 10% to 20%. Spraying pesticides is the only control method. The average spraying is 3 to 4 times. The labor is time-consuming, the cost is high, and the residue of pesticide spraying directly threatens the food safety of rice. [0003] According to the pesticide registration information of the Ministry of Agriculture, my country's current pesticide formulations for the prevention and treatment of t...
