Abstract
The present invention relates to it is a kind of containing trichlopyr and florasulam or again plus active ingredient C compound herbicide, wherein C is the one kind in fluroxypyr, MCPA,MCP,methoxone, azoles humulone, for wheat, paddy rice, sugarcane field after seedling cauline leaf process, broad leaved weed is prevented and kill off.
Description
Technical field:
The invention belongs to agriculture herbicide field, it is related to a kind of herbicide containing trichlopyr and florasulam,
Broad leaved weed is prevented and kill off for wheat, paddy rice, sugarcane field after seedling cauline leaf process.
Technical background:
Herbicide is reasonably compounded, and can reach prevention effect more more preferable than single dose, reduces the wind that weeds develop immunity to drugs
Danger, greatly reduces the purpose of the difficulty of exploitation new herbicides.Using complex weedicide, the product that weeds are caused can be not only reduced
Amount loss, increases agricultural incomes, it is often more important that weeds is controlled effectively, the input that can reduce cost can be saved again
Save labour.
Due to the exploitation of novel pesticide, not only investment risk is big, and environmental protection and food security require it to improve, limit
System adds sternly, so its construction cycle is more long, and scientific and reasonable agriculture chemical compounding can not only improve prevention effect, increase quick-acting
Property, extend the lasting period, expand preventing and treating spectrum, dosage, reduces cost etc. are reduced, but also can overcome or delay harmful organism
The generation or development of resistance, extend the service life of agricultural chemicals, reduce environmental pollution, and Protect natural enemies, biometric safeguard diversity keeps
The ecological balance.
Built agent can be also divided into binary built agent and Recompounded multielement agent by the pesticide variety number according to composition built agent.By two
The built agent for planting agricultural chemicals single dose composition is referred to as binary built agent:The built agent being made up of three kinds or more agricultural chemicals single dose is referred to as
Recompounded multielement agent.The overwhelming majority is binary built agent in agriculture chemical compounding agent, and Recompounded multielement agent is less.
The present invention is that on the basis of substantial amounts of experiment, early stage has applied for Patents CN201610786514.3, relates to
And, the composition of quinmerac, trichlopyr and florasulam, follow-up experiment be further discovered that trichlopyr and
Florasulam and combination and fluroxypyr, MCPA,MCP,methoxone, azoles humulone compounding it is most to wheat paddock etc. miscellaneous
Grass has obvious synergistic effect.After further study, the present invention is completed.
The content of the invention:
The technical problem to be solved in the present invention is to provide a kind of significant herbicide of synergistic effect, for wheat, paddy rice, sweet
Sugarcane field after seedling cauline leaf process prevent and kill off broad leaved weed.In order to solve the above technical problems, present invention offer technical scheme is as follows:
A kind of compound herbicide containing trichlopyr, florasulam, it is characterised in that described herbicide is with three
Chlorine pyrrole fluoroacetic acid, florasulam are principle active component, and the weight ratio of trichlopyr and florasulam is 1:2-80:
1, preferred ratio is 1:1-1:50.In further technical scheme, active ingredient can also include active ingredient C, wherein C
For the one kind in fluroxypyr, MCPA,MCP,methoxone, azoles humulone, trichlopyr and florasulam and active ingredient C's
Than being 5-80:0.1-10:0.5-60, preferably 5-50:1-10:0.1-50, is still more preferably 5-10:1-5:1-10.
In compound herbicide, the content of active ingredient is 1-85%, preferably 20-75%.
Herbicide of the invention is used for wheat, paddy rice, sugarcane field after seedling cauline leaf process, prevents and kill off broad leaved weed.
The preparation formulation that herbicide of the present invention can be prepared according to the method well known to those skilled in the art of the present technique, including
It is water dispersible granules, wettable powder, wet seed dressing, missible oil, suspending agent, oil suspending agent, suspension emulsion, suspension seed-coating agent, aqueous emulsion, micro-
Emulsion etc.;
Known auxiliary agent has emulsifying agent, wetting dispersing agent, suspending agent, disintegrant, binding agent, antifreezing agent, thickener, stabilization
Agent, defoamer etc.;
The advantage of compound herbicide of the invention is:
1st, Herbicidal combinations of the present invention have synergistic function, and raising uses herbicidal effect.
2nd, Herbicidal combinations of the invention reduce drug cost by the mixed of herbicide, expand herbicidal spectrum, improve
Herbicidal effect, is not likely to produce the resistance to the action of a drug, to crop safety.
Specific embodiment
With reference to embodiment to further instruction of the present invention, the percentage in embodiment is weight ratio, but this hair
It is bright to be not limited thereto.
With reference to embodiment to further instruction of the present invention, the percentage in embodiment is weight ratio, but this hair
It is bright to be not limited thereto.
1st, toxicity is determined
To further appreciate that the synergy of the mixture to weeds of the application, the present inventor is to trichlopyr, double fluorine
Sulphur grass amine and fluroxypyr, MCPA,MCP,methoxone, the mixture of azoles humulone have carried out cauline leaf process synergy toxicity measure.
Test material:Clearvers, chickweed.
Test method:
A certain amount of weeding active ingredient active compound is weighed, fully after dissolving, single dose mother liquor is configured to respectively, according to mixture mesh
Setting series proportioning, each proportioning set 5~7 concentration gradients.Representative sensitivity is selected according to single dose herbicidal spectrum
Weed seed, cultivates standby to the heart of 3 leaf 1.By after the weeds cauline leaf process for selecting numbering, incubated at room temperature in illumination box is placed on
20 days, prevention effect (fresh weight preventive effect or strain preventive effect) is calculated, then calculate ED with least square method50(95% confidence limit), then use
The abundant methods of Sun Yun calculate co-toxicity coefficient (CTC).Co-toxicity coefficient (CTC) >=120 shows as synergistic effect;Co-toxicity coefficient (CTC)≤80
Show as antagonism;80 < co-toxicity coefficients (CTC) < 120 show as summation action.Test result is shown in Table 1-8.
