Reagent agent: the 90% triazole acyl grass former medicine of amine and the former medicine of 96% Bing Que Evil humulone.
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 2, triazole acyl grass amine and Bing Que Evil humulone are to the synergy measurement result of barnyard grass
As shown in Table 2, triazole acyl grass amine and Bing Que Evil humulone 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 3:1 (by weight), synergistic function is the most remarkable, and co-toxicity coefficient is 250.43.Visible triazole acyl grass amine and Bing Que Evil humulone is composite has reasonability and feasibility.
Table 3, triazole acyl grass amine and Bing Que Evil humulone are to the synergy measurement result of difformed galingale herb
As shown in Table 3, triazole acyl grass amine and Bing Que Evil humulone 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 3:1 (by weight), synergistic function is the most remarkable, and co-toxicity coefficient is 236.40.Visible triazole acyl grass amine and Bing Que Evil humulone 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 60% triazole acyl grass amine third alkynes Evil humulone wetting powder (45:15), process 2 is 40% triazole acyl grass amine third alkynes Evil humulone water dispersible granules (30:10), process 3 is 20% triazole acyl grass amine third alkynes Evil humulone aqueous suspension agent (15:5), process 4 is 10% triazole acyl grass amine wetting powder, process 5 is the 80% the third alkynes Evil humulone wetting powders, 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 short arrowhead 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.
