Problems solved by technology

However, the use of these high-efficiency and super-efficient herbicides brings unpredictable environmental damage and ecological risks to the environment and ecology, and, due to their poor or no selectivity, causes phytotoxicity to subsequent crops and surrounding crops, Although genetically modified crops can be used to solve this problem to a certain extent, genetically modified crops may have greater ecological risks that are difficult to predict. Therefore, genetically modified crops cannot be fully accepted by the public, the government and the law

Abstract

The invention relates to an organic acid herbicides combination, which belongs to pesticides technology field. The invention is characterized in that active component contained in the invention is 5 percent to 25 percent of the total weight. The active component is single compound which accords with general formula I or a composition of a plurality of compound, and the general formula is RCOOH, and wherein R is straight-chain or branching chain alkyl of 1-5 carbon atom, or hydroxyl group replaced straight-chain or branching chain alkyl of 1-5 carbon atom, or benzene ring, or 1-2 hydroxyl or methoxy replaced benzene ring. The organic acid herbicides combination has low production cost, good weed control effect and good environmental compatibility, and is safe to people. The invention has low residue, and makes no difference to later sensitive crop. The weed can not develop resistance easily.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and specifically relates to a herbicide composition with broad-spectrum herbicidal activity, which uses organic acids as active compounds and ketone compounds as synergists. Background technique [0002] It has been more than 60 years since the development of chemical herbicides, and hundreds of commercial herbicides have been developed and applied. With the deepening of research on herbicides, scientists have not only classified herbicides from the structure, but further Deepen to classify herbicides in terms of mode of action and target of action. People explore the sites of action of various herbicides more deeply, study their inhibitory pathways and target enzymes, and interpret the root cause of herbicides inhibiting plant growth or causing plant death. Metabolic mechanism research to evaluate its impact on the ecological environment, so as to design and screen...
