Sulfometuron Methyl+Oxyfluorfen；Afterwards by above-mentioned each reagent dilute with water, medicament dilution is obtained.
Investigation method：
Target damage symptoms and growth inhibition situation are estimated after test process 21d, and claim aerial part fresh weight,
Calculate fresh weight inhibition (%).
Evaluation to the mixed synergistic effect for applying middle display of two or more herbicidal active components is to be based on
“CalculationSynergistic and Antagonistic Response of Herbicide
What Colby ' the s methods described in Combinations " (Weeds 15/1 (1967), S.R.Colby) determined.
In formula, X be halosulfuronmethyl with certain dosage when alone to the fresh weight inhibition of target weeds.
Y be Oxyfluorfen with certain dosage when alone to the fresh weight inhibition of target weeds.
E0To the reason of target weeds fresh weight inhibition during for halosulfuronmethyl and two kinds of pharmacy mix of Oxyfluorfen
By value.
To the reality of target weeds fresh weight inhibition when E is halosulfuronmethyl and two kinds of pharmacy mix of Oxyfluorfen
Measured value.
If the actual control of weeds rate (E) observed in biologic test exceedes uses Colby ' s methods
Desired value (the E being calculated0), then it represents that the effect of Herbicidal combinations is more than the summation of each agent effectiveness, this
Mean that composition has synergistic effect.
Table 1 shows the Herbicidal combinations of halosulfuronmethyl+Oxyfluorfen to barnyard grass in greenhouse (after administration
21 days) synergistic activity.
