Abstract

The invention relates to the field of pesticide preparations and discloses a weeding composition. The weeding composition disclosed by the invention comprises ametryn and one of 2,4-D isooctyl ester, 2,4-D isobutyl ester, 2,4-D butyl ester, 2,4-D ammonium salt, 2,4-D isopropylamine salt, 2,4-D-dimethylamine salt, 2,4-D sodium salt or 2,4-D potassium salt. Compared with a single agent, the weeding composition produces an obvious synergistic effect, reduces the use level of active ingredients, increases safety, delays the generation of pesticide resistance of weeds, reduces pesticide residues in the soil and the drifting of pesticides, and facilities the sustainable development of the environment. In the meantime, the weeding composition disclosed by the invention has dual effects of stem and leaf treatment and soil sealing and can be widely applied to the field of agriculture. An agrochemical preparation containing the weeding composition provided by the invention is prepared from the weeding composition, which is used as the main ingredient, and auxiliary materials, and is simple in preparation method and easy for the industrial production.

Description

technical field [0001] The present invention relates to the technical field of pesticides, in particular to a herbicidal composition, especially an active ingredient composed of 2,4-D isooctyl ester, 2,4-D isobutyl ester, 2,4-D butyl ester , 2,4-D ammonium salt, 2,4-D isopropylamine salt, 2,4-D dimethylamine salt, 2,4-D sodium salt or 2,4-D potassium salt and a A binary herbicidal composition of net composition. Background technique [0002] Corn is one of the most widely distributed food crops in the world, and its planting area is much higher than that of wheat and rice. There are two famous corn golden belts in the world, located in the United States and China. China is the world's second largest corn producer and also the world's second largest consumer. Corn is the most suitable variety of industrial raw materials among the three major food crops, and it is also the most processed food crop. The corn processing industry is characterized by large processing space, lo...
