Description
Technical field
The present invention relates to herbicide field, specifically a kind of high-efficiency ammonia chloropyridines weeds herbicide.
Background technology
With world population sustainable growth, human lives' quality is improved constantly, and efficient, safety pesticide has become world's agriculture
The developing direction of medicine, the need for the powerful guarantee and the human society harmonious development that solve Food Security.Over nearly 20 years, agricultural chemicals
Most fruitful in exploitation is that numerous heterocyclic compounds are developed to hyper-active pesticide.And in heterocyclic compound, nitrogen heterocyclic ring
Compound, especially pyridine derivate are the most prominent again, not only there is bactericide, an insecticide, and have an efficient herbicide,
This has opened up new world for the development of chemical pesticide.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of high-efficiency ammonia chloropyridines weeds herbicide, grass can be prevented and kill off
Section weeds, can prevent and kill off broad leaved weed, and work well again.
The technical scheme is that：
A kind of high-efficiency ammonia chloropyridines weeds herbicide, includes glyphosate and picloram, glyphosate and ammonia chlorine pyrrole
The weight/mass percentage composition of pyridine acid is 30-the 36% of the weeds herbicide total amount, wherein, the matter of glyphosate and picloram
Amount is than being 28-32：2-4.
Described weeds herbicide also includes auximone, and its mass percentage content is that the weeds herbicide is total
The 3-5% of amount.
Described glyphosate and the weight/mass percentage composition of picloram are 30-the 33% of the weeds herbicide total amount,
Wherein, the mass ratio of glyphosate and picloram is 28-30：2-3.
Described glyphosate and the mass ratio of picloram are 30：2.
Described auximone selects synthetic auxin, specially 2,4- dichlorphenoxyacetic acids.
Its mass percentage content of described 2,4 dichlorophenoxyacetic acid is the 4% of the weeds herbicide total amount.
Beneficial effects of the present invention are：
The synergy after mixture is evaluated with Sun Yunpei co-toxicity coefficient method, glyphosate and picloram is as a result shown
Mass ratio is 28-32：2-4 co-toxicity coefficient is significantly greater than 120, reaches notable synergistic effect, illustrates glyphosate and ammonia chloropyridine
The mass ratio of acid is 28-32：2-4 ratio mixtures have synergistic effect, wherein, the mass ratio of glyphosate and picloram is
30：The effect of 2 compound synergics is maximum, and weeds are had significant synergies.
Security test experiment to crops shows that glyphosate picloram compounding cauline leaf process suppresses farming
The ED of thing growth 10%10=1968.0878, suppress the ED of weed growth 90%90=273.8563, selectivity factor is
1968.0878/273.8563=7.19>2, it is believed that the medicament has obvious selectivity, and glyphosate and picloram are to agriculture
Crop has good security.
Weeds herbicide of the present invention was shown by the field control effectiveness test of 2 years, in the leaf phase of crops 3, weeds 2-5
Leaf does not wait the phase, and crops have no symptom of chemical damage from dispenser to maturity period, to Crop securify.The preventive effect of weeds reaches 90% in 10 days
More than, reach more than 95% within 30 days, with the increase of dosage, preventive effect is remarkably reinforced, a dispenser can control crop whole
Weeds in growth period, not only herbicidal effect is notable, and environmentally friendly, on second stubble crop without influence.
Compared with prior art, weeds herbicide of the present invention can prevent and kill off grassy weed, and it is miscellaneous to prevent and kill off broad-leaved again
Grass and sedge weed, to Crop securify, and on succession crop without influence, have a good application prospect.

Embodiment 4
Cauline leaf process synergy toxicity is determined：
1st, test objective：Under greenhouse experiment, using pot-culture method, high-efficiency ammonia chloropyridines weeds herbicide is studied
Herbicidal effect, and with Sun Yunpei co-toxicity coefficient method evaluate the two different proportion it is mixed after synergy type.
2nd, for studying thing：Rice varieties-Feng Liangyou；For examination weeds：Moleplant seed, barnyard grass, cogongrass, the rhizome of nutgrass flatsedge, Bermuda grass
(field harvesting upper one year seed, germination percentage is more than 85%).
3rd, the culture of experimental condition and examination material：The culture of test material, 25-30 DEG C of temperature are carried out in illumination cultivation room.
During experiment, every kind of weed seed 30-40 are uniformly put into basin, earthing 0.5cm, weeds should supplement growth institute during cultivating
Need moisture.The regular moisturizing (not watered in 2 days after medicine) in the way of bottom is seeped water, keeps soil moisture.
4th, reagent agent：95% glyphosate technicals；95% picloram active compound.Weighed with electronic balance quantitative above-mentioned
Active compound, adds appropriate emulsifying agent, with acetone solution, above-mentioned active compound finally is diluted into institute with the 0.1% Tween 80 aqueous solution
