Abstract

The present invention relates to a herbicide. It is composed of bromoxynil, dimethyltetrachlorosodium and atrazine with the mixing ratio of 1-100:1-100:1-100. Its makes all the components possess synergistic aclcon, and it is specially used for eliminating field broad-leaf weeds of crops of wheat and corn, etc.

Description

technical field [0001] The present invention relates to a kind of herbicide, especially a kind of herbicide composed of bromoxynil, 2-methyl-4-chlorosodium (chemical name is 2-methyl-4-chlorophenoxyacetic acid sodium) and atrazine (chemical name is 2-chloro -4-ethylamino-4-isopropylamino-1,3,5-triazine). Background technique [0002] Bromoxynil is a contact herbicide, which can effectively control broad-leaved weeds such as wheat, corn, velvetleum, cocklebur, polygonum, quinoa, amaranth, syringa, field flowers, pig hairy, and longcai , especially for atrazine-resistant weeds such as ash, amaranthus, black nightshade and Polygonum, it has a good control effect, and it is safe for gramineous crops, and there is no residue in crop stems and grains. It can be used during the long growth period of crops, from the first and second leaves of the cereal plant to the last leaf growth, such as the 2 to 8 leaf stage of corn. Sodium 2M 4 Chloride is a conventional dry field herbicide ...
