Description

A kind of herbicidal composition and its application
Technical field
The invention belongs to herbicide fields, and in particular to a kind of herbicidal composition and its application.
Background technique
Herbicid resistant is global challenges.Currently, effective resistant weed administering method mainly uses: one, being to take Different role mechanism herbicide mixture achievees the purpose that effectively to control weeds and delaying drug resistance development;It two, is to take weeds early stage It administers, in the processing of weeds most closing stage, achieves effective control weeds and reduce the purpose that radix occurs for weeds.The prior art is It prevents and kill off rice field gramineae weed, broadleaf weeds, sedge weed and effectively solves the problems, such as resistant weed, be all made of above-mentioned two kinds Weed control method.But the problem is that: first is that Seal treatment, since different weeds emergence peaks are different, as grass family is miscellaneous Barnyard grass, semen euphorbiae 3-10 days after broadcasting are peak of being unearthed in grass, and sedge weed, broadleaf weeds are out of grass late, 15 after generally broadcasting It could be unearthed to 25 days, and the closing medication phase is difficult to take into account, and often need secondary medication: second is that cauline leaf process, due to weeds radix Greatly, grass phase is complicated, and careless age is different, and cauline leaf process need to increase dosage, and effect is poor.2-3 use is generally required in actual use Medicine just can solve all weeds, time-consuming.
Therefore, use cost can be reduced, delay Weed Resistance, is environmentally safe, can effectively solve be lauched by designing one kind Rice field resistant weed problem is very urgent.
Summary of the invention
The object of the present invention is to provide a kind of broad weed-killing spectrum, to the effective herbicidal composition of control of weeds and its answer With.
The present inventor is in the course of the research it was unexpectedly observed that by with different structure type and mechanism of action Furans sulphur humulone, bensulfuron-methyl and mefenacet are used in compounding, be not only not in pharmacological property offset or other side effects, on the contrary Also there is apparent synergistic effect, can improve to a greater degree these three components to annual and perennial gramineae weed and The preventive effect of broadleaf weeds, while degrass spectrum when these three components are used as single component is expanded, and to crop Safety is also high.
The first purpose of this invention is to provide a kind of herbicidal composition as a result, wherein the herbicidal composition Active constituent contains furans sulphur humulone, bensulfuron-methyl and mefenacet.
Second object of the present invention is that providing said herbicidal composition is preventing and treating annual and perennial grass family Application in weeds and broadleaf weeds.
It is annual in prevention and treatment paddy field and for many years that third object of the present invention is to provide said herbicidal composition Application in raw gramineae weed and broadleaf weeds.
Specifically, herbicidal composition provided by the invention, has the advantage that
Herbicidal composition provided by the invention shows fabulous synergistic effect, mixed composition compared with its single dose and Its double agent significantly improves herbicidal effect, reduces the dosage of pesticide, thus reduces the drug cost of peasant and to ring The influence degree in border.
Herbicidal composition provided by the invention expands the degrass spectrum of herbicide, uses herbicide group provided by the invention A variety of weeds can be prevented and treated simultaneously by closing object, easy to use efficient, be had to annual and perennial gramineae weed and broadleaf weeds Good control efficiency.
Herbicidal composition provided by the invention is the compounded combination with the herbicide of different role mechanism, so that The weeding characteristic of the herbicide of each composition is had complementary advantages well, can effectively delay weeds to the generation of single dose resistance and Progress.
Other features and advantages of the present invention will the following detailed description will be given in the detailed implementation section.
