Comprehensive weeding composition of paddy field

Abstract

The invention discloses a comprehensive weeding composition of a paddy field. The weeding composition contains active ingredients such as penoxsulam, pyrazosulfuron-ethyl and pretilachlor, wherein the mass ratio of penoxsulam to pyrazosulfuron-ethyl to pretilachlor is (1.2-3): (0.5-2): (20-35). The comprehensive weeding composition can be used for the pre-emergence treatment, and also can be used for the post-emergence treatment; moreover, a good effect for removing and controlling the gramineae weeds, broadleaf weeds and cyperaceae weeds is good. The weeding composition is safe to the paddy rice, wide in herbicide controlling spectrum, small in consumption amount and low in production cost.

Description

technical field [0001] The invention belongs to the technical field of pesticide herbicides, and in particular relates to a comprehensive herbicide composition for paddy fields. 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 all of East and Southeast Asia, eat rice. Production is 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 sowing area accounts for 1 / 4 of the country's food crops, about 35 million hectares per year, while the output accounts for more than half. Regardless of the planting area and output, it ranks first in my country's food crops. There have always been a large number of weeds in the paddy fields of all rice-growing areas in my country. The a...
