Description
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 and mefenacet are used in compounding, and are not only not in pharmacological property counteracting or other side effects, also have on the contrary bright
Aobvious synergistic effect can improve both components to annual and perennial gramineae weed and broadleaf weeds to a greater degree
Preventive effect, while expanding degrass spectrum when both components are used as single component, and to crop safety
It is 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 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, and mixed composition is bright compared with its single dose
It is aobvious to improve herbicidal effect, the dosage of pesticide is reduced, thus reduce the drug cost of peasant and the influence to environment
Degree.
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.
