Abstract
The invention relates to weeding composition containing bentazone and carfentrazone as well as oxaziclomefone. The effective components of the weeding composition are bentazone and carfentrazone as well as oxaziclomefone, and the weight part ratio of bentazone, carfentrazone and oxaziclomefone is (1-40):(1-15):(1-15). The weeding composition has a synergistic effect, expands a weeding spectrum, reduces the pesticide consumption, alleviates the environmental pollution and delays the pesticide resistance of the weeds, and an effect of preventing and removing annual weeds in paddy fields is remarkably superior to that of a separately used individual weedicide.
Description
Technical field
The present invention relates to agricultural chemicals Herbicidal combinations and application thereof, specifically a kind of Herbicidal combinations that is active ingredient with bentazone, azoles humulone He oxaziclomefone, is mainly used in and prevents and kill off paddy field annual weed.
Background technology
Bentazone (bentazone): selectivity contact killing type herbicide after seedling, for the process of weeds cauline leaf in seedling stage, is mainly used in the crops such as paddy rice, soybean, peanut, wheat, prevents and kill off broad leaved weed and sedge weed, invalid to grassy weed.
Azoles humulone (fcarfentrazone-ethyl): be a kind of triazolineone contact killing type selective herbicide, is applicable to wheat, barley, paddy rice, seeding corn and other crops prevent and kill off broad leaved weed and sedge weed.
Oxaziclomefone (Oxaziclomefone): belong to organic heterocyclic class weed killer herbicide, there is the features such as low, the suitable dispenser phase length of active ingredient usage amount, lasting period length, higher to the selection safety of paddy rice, the multiple weeds such as barnyard grass, waterwort, moleplant seed, difformed galingale herb can be prevented and kill off.
By the screening of different pesticide species compounded formula, filter out rational formula, effectively can improve the actual control efficiency to disease pest and weed, expanding prevention is composed, reduce dosage, reduce costs, alleviate the pollution to environment, delaying the drug-fast generation of disease pest and weed, is the important means of the agriculturally disease pest and weed comprehensive regulation.The present inventor to bentazone, azoles humulone He oxaziclomefone ternary built use conduct in-depth research, a large amount of formula indoors screening and field medicine effect test basis on, find that bentazone, azoles humulone are with oxaziclomefone carries out mixture, within the scope of certain mixed ratio, obvious synergistic function is shown to paddy field annual weed, after further study, the present invention is completed.
Not yet find bentazone, azoles humulone He the relevant report of oxaziclomefone ternary built at present.
Summary of the invention

Assays Example 1: indoor biological determination of activity.
Reagent agent: 95% bentazone raw pesticide, the former medicine of 90% azoles humulone and the former medicine of 97% oxaziclomefone.
For examination target: Monochoria vaginalis (Monochoria vaginalis), barnyard grass (Echinochloa crusgalli).
Medicament configuration design: bentazone single dose is configured to 50,150,250g.a.i./ha solution for standby, azoles humulone single dose is configured to 2,6,10g.a.i./ha solution for standby, oxaziclomefone single dose is configured to 3,8,13g.a.i./ha solution for standby, bentazone, azoles humulone is with oxaziclomefone mixture is configured to 50+2+3, 50+2+8, 50+2+13, 50+6+3, 50+6+8, 50+6+13, 50+10+3, 50+10+8, 50+10+13, 150+2+3, 150+2+8, 150+2+13, 150+6+3, 150+6+8, 150+6+13, 150+10+3, 150+10+8, 150+10+13, 250+2+3, 250+2+8, 250+2+13, 250+6+3, 250+6+8, 250+6+13, 250+10+3, 250+10+8, 250+10+13g.a.i./ha solution for standby.
Test method: at the in-built quantitative soil of the polypots of high 6cm, diameter 9cm, will for 15 ~ 20 sowings of examination target weed seed in polypots, be placed in greenhouse after the fine earth that lid 0.5 ~ 1cm is thick and cultivate, treat that weeds grow to the 2-3 leaf phase and carry out spraying process, every alms bowl spraying liquid 1mL, often process repetition 4 times, and set the process not containing medicament as contrasting.After process, examination material is placed in greenhouse and cultivates, and the growing state of routine observation target weeds, estimates target damage symptoms and growth inhibition situation, and claim acrial part fresh weight after 20d, evaluates medicament to the toxicity action of target weeds with target fresh weight inhibition.
Investigation method: estimate target damage symptoms and growth inhibition situation after test process 20d, and claim acrial part fresh weight, calculate fresh weight inhibition (%).
Synergy evaluation method: evaluate weed killer herbicide mode of application (NY/T1155.7-2006) according to Colby method, its formula is: E
0=X × Y × Z/100
2, in formula, X be bentazone alone with certain dosage time be the percentage of contrast to the fresh weight inhibition of target weeds; Y be azoles humulone alone with certain dosage time be the percentage of contrast to the fresh weight inhibition of target weeds; Z Wei oxaziclomefone alone with certain dosage time be the percentage of contrast to the fresh weight inhibition of target weeds; E
0for bentazone, azoles humulone He oxaziclomefone three kinds of pharmacy mix time be the theoretical value of percentage of contrast to target weeds fresh weight inhibition; E is bentazone, azoles humulone He oxaziclomefone three kinds of pharmacy mix time be the measured value of percentage of contrast to target weeds fresh weight inhibition.
Evaluation criterion: work as E
0synergistic effect is expressed as, as-10%≤E during-E>10%
0be expressed as summation action during-E≤10%, work as E
0antagonism is expressed as during-E<-10%.
As can be seen from the Toxicity Determination result of table 1 and table 2, bentazone, azoles humulone and oxaziclomefone mixture respectively process the E to Monochoria vaginalis and barnyard grass
0-E (%) value is all greater than 10%, illustrates that three is composite and all has synergistic function to Monochoria vaginalis and barnyard grass.As can be seen here, bentazone, azoles humulone are with oxaziclomefone Ternary has reasonability and feasibility.
Table 1, each chemicals treatment are to the Toxicity Determination result of Monochoria vaginalis.
Table 2, each chemicals treatment are to the Toxicity Determination result of barnyard grass.
Assays Example 2: field control effectiveness test.
Experimental field select Monochoria vaginalis and barnyard grass that more paddy field occurs to carry out.8 process are established in test altogether, often 3 repetitions are established in process, process 1 is 25% bentazone azoles Cao Tong oxaziclomefone oil-suspending agent (example of formulations 3), process 2 is 24% bentazone azoles humulone oil-suspending agent (23:1), process 3 is 24% to go out Cao Song oxaziclomefone oil-suspending agent (23:1), process 4 is 2% azoles Cao Tong oxaziclomefone oil-suspending agent (1:1), process 5 is 25% bentazone suspending agent, process 6 is 10% azoles humulone wetting powder, process 7 is 1% oxaziclomefone suspending agent, process 8 is contrast (not dispenser not weeding), within after medicine 30 days, add up each process number of weeds amount and calculate preventive effect.
Table 3, each chemicals treatment prevent and kill off the field control effectiveness test result of paddy field weed.
As can be seen from the field test results of table 3, when within after medicine 30 days, 25% bentazone azoles Cao Tong oxaziclomefone oil-suspending agent usage amount of the present invention is 350-450g.a.i./ha, all obviously be higher than each single dose or binary built use to the Monochoria vaginalis of paddy field and the preventive effect of barnyard grass, in pilot survey process, do not send out it produces poisoning to paddy rice simultaneously.As can be seen here, said composition is worth applying in agricultural production.
