Problems solved by technology

[0004] Fenpyramid can effectively control gramineous weeds, but it has poor control effect on broad-leaved weeds and sedge weeds, and there are grasses, broad-leaved and sedge weeds in the field at the same time. Therefore, in order to make up for the single Insufficient herbicides, it is necessary to compound single-agent herbicides

Abstract

The invention relates to the technical field of pesticides, and discloses a rice mixed herbicide. The herbicide comprises two active ingredients of metamifop and cyclosulfamuron, wherein the weight ratio of the two active ingredients is 1:5-65:1; and the mass percentage of the two active ingredients is 1-90% of the mixed herbicide. By mixing the two active ingredients of metamifop and cyclosulfamuron, complementarity of each ingredient for eradicating weeds is increased and shortages when each ingredient is used alone are supplemented. The herbicide can not only prevent and eradicate annual gramineae weeds in rice fields, but also can prevent and eradicate broadleaf weeds and cyperaceae weeds, and has significant synergistic effects. The herbicide composition has not only obvious effects for eradicating weeds but also good security for the rice, has no influence on subsequent crops, and is an ideal herbicide.

Description

【Technical field】 [0001] The invention belongs to the field of agricultural plant protection, and relates to a herbicide composition with improved performance, in particular to a herbicide synergistic composition containing two active ingredients of fenpyramid and cyprosulfuron-methyl. 【Background technique】 [0002] Rice is not only the most important food crop in my country, but also one of the main food crops in the world. Nearly half of the world's population, including almost the entire population of East and Southeast Asia, depend on rice for food, and production occurs on every continent except Antarctica. In the late last century, the average annual rice output in the world was about 400 billion kilograms, and the planting area was about 145 million hectares. my country's rice planting area accounts for 1 / 4 of the country's food crops, about 35 million hectares per year, and the output accounts for more than half. Regardless of the planting area and output, it rank...
