Abstract
The invention relates to a weed killing composition containing ipfencarbazone and benzobicylon. The effective component is composed of ipfencarbazone and benzobicylon, and the weight ratio of ipfencarbazone to benzobicylon is 10:1-1:10. The weed killing composition has a prominent synergetic effect, and can be used to kill annual weeds in the paddy rice field. The weed killing effect is prominently improved, compared with the effect of single component. The weed killing spectrum is enlarged, the pesticide using amount is reduced, the pollution to the environment is reduced, the generation of drug resistance of weeds becomes more difficult, and the service life of the weed killing composition is prolonged therefore.
Description
Technical field
The present invention relates to agricultural chemicals Herbicidal combinations and application thereof, specifically a kind of with triazole acyl grass amine and the benzobicylon Herbicidal combinations that is active ingredient binary built, be applied to and prevent and kill off paddy field annual weed.
Background technology
Triazole acyl grass amine (ipfencarbazone): be a kind of novel triazolineone weed killer herbicide, be mainly used in paddy field and prevent and kill off grassy weed, broad leaved weed and the sedge weeds such as barnyard grass, moleplant seed, difformed galingale herb, Monochoria vaginalis, mexicana.
Benzobicylon (benzobicylon): the albinism paddy field post-emergence herbicide being double-octane class is the inhibitor of hydroxyphenyl pyravate dual oxide enzyme.Its selectivity between paddy rice and weeds is high, to annual broadleaf weeds such as Monochoria vaginalis, Procumbent Falsepimpernel classes; Firefly Lin, Herba Cyperi Glomerati, needle spikesedge herb Deng Jumang cyperus iria section weeds; The difficulty such as fishscale bamboo grass, rice shape not plump shell grass, false rice, agrostis stolonifera, potamogeton grass is cut weeds all effective.
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 composite use of the present inventor to triazole acyl grass amine and benzobicylon conducts in-depth research, a large amount of formula indoors screening and field medicine effect test basis on, surprisingly triazole acyl grass amine and benzobicylon carry out composite, within the scope of certain compound proportion, significant synergistic function is shown to paddy field weed, after further study, the present invention is completed.
Summary of the invention

(2) indoor biological determination of activity embodiment
Reagent agent: the 90% triazole acyl grass former medicine of amine and the former medicine of 90% benzobicylon.
For examination target: Monochoria vaginalis (Monochoria vaginalis), barnyard grass (Echinochloacrusgalli), difformed galingale herb (Cyperus difformis).
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 1-2 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.Carry out statistical analysis with DPS statistical analysis software, calculate the ED of each medicament
50, and the co-toxicity coefficient (CTC value) of mixture is calculated according to the abundant method of Sun Yun.
Actual measurement toxicity index (ATI)=(standard agent LC
50/ reagent agent LC
50) × 100
In theoretical toxicity index (TTI)=A medicament toxicity index × mixture A percentage composition+B medicament toxicity index × mixture in the percentage composition of B.
Co-toxicity coefficient (CTC)=[the theoretical toxicity index (TTI) of mixture actual measurement toxicity index (ATI)/mixture] × 100.
According to the NY/T11547.7-2006 insecticide combination effect criteria for classifying: co-toxicity coefficient (CTC) >=120 shows as synergistic effect; Co-toxicity coefficient (CTC)≤80 shows as antagonism; 80 < co-toxicity coefficient (CTC) < 120 show as summation action.
Table 1, triazole acyl grass amine and benzobicylon are to the synergy measurement result of Monochoria vaginalis
As shown in Table 1, triazole acyl grass amine and benzobicylon composite in the scope of 10:1 ~ 1:10 (by weight) time, co-toxicity coefficient is all greater than 120, illustrates and shows synergistic function to Monochoria vaginalis; Especially composite with 1.5:1 (by weight), synergistic function is the most remarkable, and co-toxicity coefficient is 336.43.Visible triazole acyl grass amine and benzobicylon is composite has reasonability and feasibility.
Table 2, triazole acyl grass amine and benzobicylon are to the synergy measurement result of barnyard grass
As shown in Table 2, triazole acyl grass amine and benzobicylon composite in the scope of 10:1 ~ 1:10 (by weight) time, co-toxicity coefficient is all greater than 120, illustrates and shows synergistic function to barnyard grass; Especially composite with 1.5:1 (by weight), synergistic function is the most remarkable, and co-toxicity coefficient is 314.73.Visible triazole acyl grass amine and benzobicylon is composite has reasonability and feasibility.
Table 3, triazole acyl grass amine and benzobicylon are to the synergy measurement result of difformed galingale herb
As shown in Table 3, triazole acyl grass amine and benzobicylon composite in the scope of 10:1 ~ 1:10 (by weight) time, co-toxicity coefficient is all greater than 120, illustrates and shows synergistic function to difformed galingale herb; Especially composite with 1.5:1 (by weight), synergistic function is the most remarkable, and co-toxicity coefficient is 352.61.Visible triazole acyl grass amine and benzobicylon is composite has reasonability and feasibility.
(3) field efficacy checking embodiment
Selecting weeds that more paddy field occurs is test plot.6 process are established in test altogether, often 3 repetitions are established in process, process 1 is 75% triazole acyl grass amine benzobicylon wetting powder (45:30), process 2 is 50% triazole acyl grass amine benzobicylon water dispersible granules (30:20), process 3 is 25% triazole acyl grass amine benzobicylon aqueous suspension agent (15:10), process 4 is 10% triazole acyl grass amine wetting powder, process 5 is 25% benzobicylon suspending agent, process 6 is contrast (not dispenser not weeding), within after medicine 30 days, adds up each process number of weeds amount and calculates preventive effect.
Table 4, each chemicals treatment prevent and kill off the field control effectiveness test result of paddy field annual weed
As can be seen from the field test results of table 4, the preventive effect of the weeds such as process 1 in 30 days after medicine, process 2 and the process barnyard grass of 3 pairs of paddy fields, moleplant seed, difformed galingale herb, mexicana, Monochoria vaginalis and false rice significantly better than process 4 and process 5, will not find in pilot survey process that process 1, process 2 and process 3 pairs of paddy rice produce poisoning simultaneously.As can be seen here, Herbicidal combinations obvious synergy of the present invention, compare single dose be used alone expand herbicide spectrum, improve preventive effect, effectively can prevent and kill off the various weeds of paddy field, to crop safety, be worth applying in agricultural production.
