Description
Technical field
The invention belongs to technical field of pesticide, and in particular to it is a kind of for eliminating weed in wheat field containing diflufenican,
The composition pesticide of flufenacet and flucarbazone.
Background technology
According to statistics, every year because of disease, worm, crop smothering loss 14%, the loss that wherein crop smothering is caused is about 11% to the production of world's cereal,
Weed infestation is the key factor for restricting crop yield.The use of chemical herbicide be agricultural modernization important symbol it
One.In recent years, the sales volume of herbicide increases year by year, and the proportion for accounting for agricultural chemicals sales volume increases year by year, and administration area expands year by year.
Wheat is served as the second largest cereal crops of China in people's problem of food and clothing and sociopolitical stabilization is solved
Vital effect, there is consequence in the world.But the serious of wheat paddock crop smothering is to restrict its high yield, stable yields
Major obstacle.At present, many patterns using " kills, two benefits " of preventing and kill off of weeds of wheat are carried out, and are had not for different phase
With herbicide kind it is available, but most kind it is difficult to ensure that a drug and keep in wheat whole breeding time without grass,
The increase of times for spraying undoubtedly substantially increases cost accounting, has also aggravated the influence to environmental ecology.Therefore, exploratory development
Wheat paddock first use and keep in wheat whole breeding time without grass safe efficient herbicide be particularly important.
Diflufenican, chemical name：2,4,-two fluoro- 2- (methylphenoxy between α, α, α-trifluoro) -3- pyridine acyl benzene
Amine.Category picolinamide class herbicide, the main bud by seedling absorbs, by the suppression to phytoene dehydrogenase, resistance
Hinder carotenoid to generate, be selective before seedling, herbicide after seedling, also with selection systemic action.
Flufenacet, chemical name：The fluoro- N- isopropyls-N-2- of 4- (5- Trifluoromethyl-1s, 3,4- thiadiazoles -2- epoxides)
Antifebrin.Category acetamide-group herbicides, cell division and growth inhibitor.
Flucarbazone, chemical name：N- (2- Trifluoromethoxyphen-ls sulfonyl) -4,5- dihydro -3- methoxyl group -4- first
Base -5- oxygen -1H-1,2,4- formamidetriazole sodium salts.Category sulfonylurea herbicide, can be absorbed, in plant by weeds root and leaf
Conduction in vivo, suppresses acetolactate synthase activity, dead so as to cause weeds to stop growing.
The content of the invention
An object of the present invention is to prevent for the problem that developed immunity to drugs to farmland weed in the prior art, single use
Except effect is poor, first use be difficult to the problem of Weed infestation in effectively control wheat whole breeding time, there is provided one kind has and increases
The composition pesticide containing diflufenican, flufenacet and flucarbazone of effect effect.
It is a further object of the present invention to provide the above-mentioned composition pesticide containing diflufenican, flufenacet and flucarbazone
Application.
Realizing the technical scheme of one of the object of the invention is：It is a kind of containing diflufenican, flufenacet and flucarbazone

（Test example 1）
This test example is the synergy of diflufenican, flufenacet and flucarbazone mixture to weeds.
Test material：Amur foxtail（Latin literary fame：Alopecurus aequalis Sobol.）And clearvers（Latin
Name：Galium aparine L.）.In May, 2015 is picked up from the suburban area wheat paddock of Jiangsu Province Changzhou, adopt under the conditions of rear room temperature from
So air-dry, load paper bag, be placed in 4 DEG C of ± 0.5 DEG C of Refrigerator stores.
Test apparatus：PWT-510 type spray towers, plum Teller AB135-S electronic balances, volumetric flask, triangular flask, beaker, amount
Cylinder, polypots, pipette, chi, scissors etc..
Test method：A certain amount of diflufenican, flufenacet and flucarbazone active compound are first weighed, adds methyl alcohol abundant
Diluted with the 0.1% Tween 80 aqueous solution after dissolving, be configured to single dose mother liquor, series proportioning is set according to mixture purpose, each is matched somebody with somebody
It is more stand-by than setting 5~7 concentration gradients.By polypots（15cm×11cm×7cm）Air-dried fine earth is filled, is oozed with polypots bottom
Filling mode, makes soil moisten completely.Soil is horse liver soil, and pH is 6.7, the content of organic matter 1.6%, is air-dried standby after sieving.Each
Polypots broadcasts amur foxtail 35, clearvers 15 respectively, broadcasts rear fine earth covering, thickness about 0.2cm.Broadcast the spraying of the leaf phase of rear weeds 2
300m is put into after treatment2Heliogreenhouse culture, keep the skin wet holding ground moistening daily.
Routine observation amur foxtail after medicine, after the emerging and emerge of clearvers seedling growing state.Investigation in 30 days is seen after medicine
Wheat ma, clearvers aerial part fresh weight, it is the preventive effect to target weeds to calculate fresh weight inhibition.Using DPS data processings
System obtains diflufenican, flufenacet, flucarbazone single dose and 16 virulence regression equations of Ternary agent, calculates
ED50Value and 95% confidence limit.Co-toxicity coefficient is calculated with the abundant methods of Sun Yun, co-toxicity coefficient is expressed as synergistic effect more than 120, less than 80
Antagonism is expressed as, summation action is expressed as between 80~120.
Result of the test：Medicine is post-processed 20 days and observed, and diflufenican, flufenacet and flucarbazone are pressed（1~50）∶（5~
80）∶（0.5~10）Ratio mixture applies rear amur foxtail and clearvers partial blade turns to be yellow to withered, to amur foxtail and clearvers
Inhibitory action rise with the increase of drug concentration, to amur foxtail and clearvers with bioactivity very high.
30 days after medicine, diflufenican, 16 Ternaries of flufenacet and flucarbazone combine the fresh weight to amur foxtail
With obvious inhibitory action, 16 proportioning co-toxicity coefficients are all higher than 120, show as synergistic effect（It is shown in Table 1）.
