5 bioassay test of embodiment
Using diflufenican as standard agent, disease index and control efficiency are calculated.Control efficiency is converted into probability value
(y), liquor strength (μ g/ml) is converted into logarithm (x), calculates concentration EC50 in virulence equation and inhibition with least square method,
The toxicity index grade co-toxicity coefficient (CTC) of medicament is calculated according to Sun Yunpei's Method.Diflufenican and 2- pyrimidine oxy-benzoic acid are derivative
Object compounding the results are shown in Table 1 to the toxicity test of Amaranthus retroflexus.
Survey toxicity index (ATI)=(standard agent EC50/ reagent agent EC50) * 100
B in the percentage composition+B medicament toxicity index * mixture of A in theoretical toxicity index (TTI)=A medicament toxicity index * mixture
Percentage composition
Co-toxicity coefficient (CTC)=[mixture surveys toxicity index (ATI)/mixtures theoretical toxicity index (TTI)] * 100
CTC≤80, composition show as antagonism, 80 < CTC < 120, and composition shows as summation action, CTC >=120,
Composition shows as synergistic effect.
The toxicity test interpretation of result of 1 Amaranthus retroflexus of table
| Medicament | EC50(μg/ml) | ATI | TTI | CTC |
| X | 10.03 | 100 | / | / |
| Y | 13.56 | 73.97 | / | / |

The synergistic function of work.
6 field control effectiveness test of embodiment
Medicament: herbicide prepared by embodiment 1 ~ 4,50% diflufenican wettable powder.
Crop: rice.Rice seedlings grow fine, robust plant, without other pest and disease damages.
Control object: the weeds such as barnyard grass, clearvers, Veronica, Monochoria vaginalis, mexicana, difformed galingale herb.
Test method:
According to the area of experimental plot, the good various medicaments of precise, and after being watered dilution, knapsack sprayer is utilized, is carried out
Even spraying.When spraying, it should be noted that the phenomenon that uniformly spraying application in experimental plot medical fluid, accomplishing no drain spray, more sprays.
20 days observation weeds death conditions after medicine, and the activity of weeding of more various medicaments.In addition, also to observe crop
Growing state, whether have phytotoxicity to investigate medicament to crop.
Test result:
2 field control effectiveness test result of table (after medicine 20 days)
| Medicament | Dosage (ga.i/ mus) | Broadleaf weeds preventive effect (%) | Gramineae weed preventive effect (%) | Total preventive effect (%) |
