Abstract
The present invention is prepared from quinclorac (dichloro-quinolinic acid) and bensulfuron methyl as main effective components through mixing according to proper proportioning. Compared with the existing herbicides for seedling beds, the present invention has broad-spectrum and high effective weed killing effect, more than 99% of prevention efficiency to broadleaf weeds, barnyard grass, short arrow head, monochoria vaginalis and rotala indica, and more than 90% of prevention efficiency to other weeds.
Description
The present invention is a kind of rice seedling bed Herbicidal combinations and production method thereof.
The kind that is used for the rice seedling bed weeding at present mainly contains molinate, quinclorac etc., but the two all can only prevent and kill off barnyard grass grass, fescue etc., and preventing and kill off of broad leaved weed almost is difficult to prove effective, and rice seedling bed weeds barnyard grass grass, fescue and multiple broad leaved weed mixed growth often, therefore, be sought after a kind of the various common weeds of rice seedling bed all being had weed killer herbicide efficiently.
Purpose of the present invention is exactly the problem at above-mentioned proposition, and a kind of can effectively prevent and kill off rice seedling bed barnyard grass grass, fescue are provided, and can prevent and kill off other broad leaved weed again, and agricultural cost is lower, a kind of rice seedling bed weed killer herbicide that safety is good.
The present invention with quinclorac (dichloro quinolinic acid) and bensulfuron-methyl for mainly containing effective constituent as prescription. being mixed processes, by a large amount of drug effect test of field zone screenings and large tracts of land weeding demonstration, determine that mu restrains as the elementary cell amount of being mixed with bensulfuron-methyl effective ingredient 0.2-3
The dichloro quinolinic acid effective ingredient that the present invention uses and the weight ratio of bensulfuron-methyl effective ingredient are 1: 0.005-0.6, its optimum weight ratio are 1: 0.05-0.12.By the weight ratio that the present invention provides, its production technology be dichloro quinolinic acid wetting powder and bensulfuron-methyl wetting powder are are fully mixed and stirred and this Herbicidal combinations.Composition of the present invention is a wetting powder, and greater than 95%, suspensibility is greater than 70% less than the fineness of 45 μ m for its particle diameter.
The present invention has the more grass effect of killing of wide spectrum with respect to molinate, quinclorac (dichloro quinolinic acid), total anti-efficient to weeds reaches more than 95%, can reach the purpose of one-time weeding, owing to adopt the mode of mixing and stirring that is mixed to obtain, and do not have by product and " three wastes " exhaust emission.
Embodiment: the 50% dichloro quinolinic acid wetting powder of 25 parts of weight and the 10% bensulfuron-methyl wetting powder adding agitator of 10 parts of weight are are evenly mixed and stirred, get this Herbicidal combinations wetting powder finished product of 35 parts of weight.
Claims (1)
1, a kind ofly prevents and kill off the Herbicidal combinations that the rice seedling bed weeds are used, it is characterized in that the weight ratio of active ingredient dichloro quinolinic acid and benzyl ethyl methyl is 1: 0.05-0.12.
