Abstract
The present invention provides mixed herbicide and its application of a kind of containing chlorine fluorine pyridine ester and dichloroquinoline humulone；Active constituent is made of chlorine fluorine pyridine ester and dichloroquinoline humulone, and the weight ratio of the chlorine fluorine pyridine ester and dichloroquinoline humulone is 1-30:20-100；It can be used for broadleaf weeds, gramineae weed and the prevention and treatment of nutgrass flatsedge.
Description
Technical field
The invention belongs to pesticide fields, and in particular to a kind of mixed herbicide of containing chlorine fluorine pyridine ester and dichloroquinoline humulone
And its application.
Background technique
Chlorine fluorine pyridine ester is novel aromatic yl pyridines first acid herbicides, is after fluorine chloropyridine ester in such herbicide
Second new compound can effectively prevent and kill off the gramineae weeds such as paddy field barnyard grass, bald barnyard, rice barnyard grass, semen euphorbiae, special-shaped Sha
The sedge weeds such as grass, chufa, cyperus iria, the rhizome of nutgrass flatsedge, miliary fimbristylis herb, piemarker, rhizoma alismatis, water amaranth, three-coloured amaranth, artemisiifolia,
The broadleaf weeds such as Chenopodiaceae, Horseweed Herb, Brittle Falsepimpernel Herb, climbing seedbox herb, Monochoria korsakowii, arrowhead, Siberian cocklebur.Drug passes through the blade and root of weeds after application
System absorbs, and has absorbability, can conduct through xylem and bast, and be accumulated in the separate living tissue of weeds, so that it is living to play weeding
Property.Due to mechanism of action novelty, known Weed Resistance problem can solve, it is environmentally friendly, to other biological safety.
Dichloroquinoline humulone is the new herbicides of China's independent research, is HPPD inhibitor, and action character is miscellaneous
Grass roots, leaf Assimilation and conductivity and work, after susceptible weeds absorb this medicine, pass through inhibit p-hydroxybenzene pyruvic acid (HPP) ester dual oxide enzyme
Synthesis, lead to the accumulation of tyrosine, make the biosynthesis block of plastoquinone and tocopherol, and then influence the biology of carotenoid
There is death after albefaction in synthesis, weeds.For preventing and kill off the especially more difficult at present Monochoria vaginalis prevented and kill off of gramineous crop, dog tail
Grass, herba digitariae and a variety of broadleaf weeds by blade or root absorption, are migrated up and down in plant, are passed rapidly after weeds application
To entire plant.
Compounding between herbicide not only can solve the problem that pesticide single dose toxicity is big, effect is poor, but also less investment, R&D cycle
It is short, and it is used interchangeably the generation for capableing of retarding action object drug resistance between different pesticides, it is imitated with ideal use
Fruit, therefore the compounding of pesticide is current research focus in the field of pesticide between different role mechanism.In the prior art not by chlorine
