Problems solved by technology

[0003] MCPA-isooctyl, a phenoxycarboxylic acid selective systemic herbicide, is mainly used for post-emergence stem and leaf treatment. The agent passes through the cuticle and plasma membrane, and finally conducts to various parts , have different effects on the synthesis of nucleic acid and protein, the drug gathers at the top of the plant growth, inhibits nucleic acid metabolism and protein synthesis, stops the growth of the growth point, and cannot stretch the young leaves, resulting in abnormal photosynthesis; the drug is transmitted to the plant through the phloem The lower part increases the synthesis of nucleic acid and protein in the stem tissue of the plant, promotes abnormal cell division, enlarges the root tip, loses the ability to absorb nutrients, causes the stem to be twisted and deformed, the sieve tube is blocked, the phloem is damaged, and the transportation of organic matter is blocked, thereby destroying normal plant viability, eventually leading to plant death
On the basis of indoor screening and field tests, the inventors of the present application have screened out the compound composition of iodosulfuron-methyl sodium salt and 2-methyl-4-chloroisooctyl, which has obvious synergistic effect, and about the weeding of the two The composition and its application have not been reported so far

Abstract

The present invention relates to a weeding composition comprising iodosulfuron-methyl sodium and isooctyl nitrate. The weeding composition has synergistic effects, wherein a weight ratio of the iodosulfuron-methyl sodium to the isooctyl nitrate is 1:10 to 1:600, preferably 1:100 to 1:200, and most preferably 2:225.

Description

technical field [0001] The invention belongs to the field of herbicide compounding, and specifically relates to a herbicidal composition containing iodosulfuron-methyl sodium salt and 2-methyl-4-chloroisooctyl. The herbicidal composition has good weeding effect, is safe for crops, and has a short residual effect period , does not affect subsequent crops, safe and environmentally friendly. Background technique [0002] Iodosulfuron-methyl sodium, a sulfonylurea herbicide, works by inhibiting acetolactate synthase. After being absorbed by weed roots and leaves, it is conducted in the plant to make the weed leaf color Chlorosis, stop growing, and die. It is mainly used in wheat fields to control gramineous weeds such as ryegrass and wild oats and various broad-leaved weeds such as pig's purse, shepherd's purse and chickweed in the early post-emergence period. The residual effect period is short, has no effect on subsequent crops, and has high compatibility and safety to the e...
