Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of Herbicidal combinations that contains two careless ethers and sulfonylurea, be used to prevent and treat paddy field weed.
Background technology
The direction of pesticide developing was to embody efficient, low toxicity, low-residual and pollution-free in recent years.Be embodied in pursuit " three height ", promptly (1) is safe, and this not only requires toxicity low, and is residual low, and nuisanceless; (2) biologically active is high; (3) selectivity is high.Therefore continue to improve the performance of present Pesticidal products, reach efficient, low toxicity, free of contamination requirement.So, select the agricultural chemicals of composite mixture just to become current first-selection and a kind of valid approach, be that the agricultural chemicals of performance complement obtains best synergistic effect through the proportioning of adjusting different agricultural chemicals.

22, can in the plant body, be conducted by weeds root system and Foliage Absorption; Its mechanism of action is mainly through suppressing the activity of acetolactate synthestase in the weeds body; Thereby hinder the synthetic of branched-chain amino acids such as leucine, isoleucine, a word used in person's names propylhomoserin, make cell stop division, cause weeds dead at last.After doing the cauline leaf processing, susceptible weeds stops growing, and the leaf look moves back green, according to different environmental conditions, just can make weeds withered fully through after several weeks.This medicine can be used for the rice transplanting Honda, also can be used for direct sowing rice field and prevents and kill off broad leaved weed and sedge weed, under high dose, the barnyard grass grass is had good inhibitory effect, and the anti-weeds flat bar bamboo trunk grass of perennial difficulty is also had stronger inhibition effect.
Fluorine pyrrole sulphur swells (flucetosulfuron), and fluorine pyrrole sulphur is grand to be a kind of sulfonylurea weed killer herbicide by the development of LG Corp of South Korea life science Co., Ltd, can be used for transplanting and the direct seading rice field; Be used for the processing of soil or cauline leaf and can effectively prevent and kill off barnyard grass grass, broad-leaved and sedge weed.
The chemical composition of each weed killer herbicide, structure and physicochemical property all are distinguishing.Therefore, they kill careless ability and scope is also different.It is narrower that some weed killer herbicide kills the grass spectrum, but have one's own knack, and can eradicate the weeds that are difficult to eliminate with other weed killer herbicide.
In recent years; People are frequent to be used and has concurrently to the safety of useful crop with to the so-called selective herbicide of the herbicidal effect of undesired plants; Even but have the weed killer herbicide of high selectivity; Because of various conditions such as the kind of meteorological condition, soil condition, crop, chemicals treatment periods, also produce poisoning sometimes in use.People are studying the use of the various poisoning palliatives of the such state of affairs of not expecting of reply.At present, China also comparatively payes attention to using with aspect the research of weed killer herbicide, is extensively thought one of important measures that weed killer herbicide rationally uses, and has worked out a series of Herbicidal compositions, has obtained bigger progress.
My company also is devoted to the research and development of Herbicidal compositions.At present, do not appear in the newspapers with pyrazosulfuron, AC322140, the grand relevant composite product of fluorine pyrrole sulphur about two careless ethers.
