Description
Technical field:
The present invention relates to technical field of pesticide preparations, be specifically related to a kind of Herbicidal combinations containing azoles quinoline grass ester and pyrrole grass ether.
Background technology:
Chemical method weeding is agriculturally one of Main Means controlling weeds.But the weed killer herbicide kind large area of single-activity component is used alone the defect often existed on Agriculture Field control of weeds in various degree, as after continuous administration, weeds easily develop immunity to drugs, herbicide spectrum is narrow, and application times is many can weighting ring environment pollution.Grass when weeds occur simultaneously is mutually complicated, and grassy weed, broad leaved weed, the mixed life of nutgrass flatsedge multiclass weeds, single-activity kind weed killer herbicide uses can not solve farmland weed.For above situation, variety classes weed killer herbicide mixture, have herbicidal spectrum wide, promote actual effect, delay herbicide resistance, time and labour saving advantage; Simultaneously effectively can also control indiscriminate use of pesticide, save cost, reduce pollution to environment.
Azoles quinoline grass ester belongs to neophyl pyrazoline compounds, and after it is absorbed by plants, by suppressing the acetyl-CoA carboxylase in plant corpus, makes fatty acid biosynthesis block, causing cell division to stop, cell membrane is damaged containing fat structure, thus causes weeds dead.Azoles quinoline grass ester activity is high, rapid-action, safer to crop, low to person poultry toxicity, little to environmental influence, resistance of rainwater washing against.It has interior absorption, after being absorbed, transfers to rapidly the growing point of blade and stem, is then delivered to whole strain, play the effect of quick management of weeds by plant leaf blade.This weed killer herbicide is mainly used in wheatland, effectively can prevent and kill off multiple important annual gramineous weed, as amur foxtail, Ah draping over one's shoulders draw the important grassy weeds such as grass, Avena, Lolium and setaria, it is high to Wheat and barley safety, and can use within the long period in late period in early days from emerging.
Pyrrole grass ether is contact killing type weed killer herbicide after a kind of pyrazoles seedling of novelty, and its mechanism of action suppresses the proporphyrinogen oxidase in plant corpus, and it plays drug effect by making protogen IX accumulation in plant cell.This medicament, after cauline leaf process, can be rapidly absorbed in plant tissue, makes plant tissue downright bad very soon, or under solar radiation, cauline leaf is dewatered withered.This medicament is mainly used in wheatland and prevents and kill off broad leaved weed, high to cereal crop selectivity.To broad leaved weeds such as clearvers, deaf nettle, chickweed, Veronica persicas, there is excellent preventive effect.Poor to cornfield gramineae weed effect.
Usually, the weeds endangering wheatland are mainly broad leaved weed and grassy weed.In order to protect wheat from Weed infestation in all directions, needing to use multiple weed killer herbicide, so just adding the risk of antagonism between each weed killer herbicide, and add dosage, add cost, the safety of harm environment and succession crop.Therefore, providing a kind of all has the wheat field herbicide of remarkable preventive effect to have important practical significance to grassy weed and broad leaved weed.
Study discovery through inventor, azoles quinoline grass ester is mixed with the pyrrole grass composite use of ether or single dose, has the effect of Synergistic.A drug can be held concurrently the multiple broad leaved weed of hazard protection wheatland and grassy weed, thus reduces dosage, reduces spraying times, farthest reduce pollution on the environment, delay the generation of herbicide resistance, and on succession crop without impact, there is huge Development volue.

Above-mentioned medicament is commercial.
With clear water in contrast.
Prevent and kill off object: amur foxtail, clearvers, Veronica.
Experimental technique:
Test is carried out in winter wheat field, is divided into multiple community, each community 30m
2, repeat 3 times, randomized arrangement, establish protection row around.Weeds 2 to 4 leaf phase medication, directed spraying.
Investigation method:
Dispenser 8 days, 25 fixed point investigation 3 place, Tian Houmei community Weed-control effect, often place's investigation 1m
2, calculating preventive effect of averaging.
Fresh weight preventive effect computing formula: preventive effect (%)=(1-process fresh weight/contrast fresh weight) × 100
The results are shown in following table:
Upper table is the complex preparation of azoles quinoline grass ester and pyrrole grass ether and respective single dose thereof to the fresh weight preventive effect of wheat weeds amur foxtail, clearvers, Veronica 8 days and 25 days.From dispenser fresh weight preventive effect after 25 days, the azoles quinoline grass ester of different dosage form, different ratio and the complex preparation of the careless ether of pyrrole in fresh weight preventive effect all higher than the preventive effect that respective single dose is used alone.From preparation effective ingredient consumption, the compound product of low dosage, compared with single dose, not only expands weeding general, has synergistic function simultaneously.Thus visible, azoles quinoline grass ester and the composite use of pyrrole grass ether are not merely superposing of respective single dose preventive effect to the preventive effect that wheat weeds produces, and have more showed obvious synergistic effect.
In sum, Herbicidal combinations of the present invention under Isodose or low dosage to wheatland annual gramineous weed and broad leaved weed preventive effect outstanding, composition is to amur foxtail, clearvers, the synergistic effect of Veronica tool, good to Safe to wheat, be the new and effective Herbicidal combinations preventing and kill off wheat paddock 1 year grassy weed and raw broad leaved weed.
