Abstract
The invention relates to a compound herbicide composition and in particular relates to a novel ternary compound herbicide composition applied in the rice, wheat, sugarcane and corn fields. The compound herbicide composition is prepared from a first active ingredient, a second active ingredient and a third active ingredient, wherein the first active ingredient is penoxsulam; the second active ingredient is 2-methyl-4-chlorophenoxy acetic acid or a derivative thereof; the third active ingredient is carfentrazone-ethyl; and the weight percent ratio of the three active ingredients is (0.1-50):(1-100):(0.1-50). The compound herbicide composition has the beneficial effects that penoxsulam, 2-methyl-4-chlorophenoxy acetic acid or the derivative thereof and carfentrazone-ethyl are subjected to ternary compounding, so that the obtained new composition has a gain effect on control of weeds in the rice, wheat and corn fields, especially has a special effect on the weeds having drug resistance in the regions at which sulfonylurea herbicides are used for a long term and is safe for afterreap crops.
Description
technical field [0001] The present invention relates to a novel compound herbicide composition, in particular to a ternary compound compound herbicide compound applied to rice, wheat, sugarcane and corn fields. Background technique [0002] Rice is one of the main food crops in the world. Nearly half of the world's population eats rice, and its production covers all continents except the South and North Pole. At the end of the 20th century, the world's annual rice output averaged about 400 billion kilograms, and the planting area was about 1.45 billion hectares. Rice is one of the important food crops in China. The sown area of rice in China accounts for about 1 / 4 of the country's food crops, about 35 million hectares per year, and the output accounts for about 50% of the total grain output. Regardless of planting area or output, it ranks first among grain crops in China. [0003] There are a large number of weeds in the rice fields of all rice-growing areas in China, es...
