Evaluation to activity of weeding after the bud of Herbicidal combinations in greenhouse
Under greenhouse experiment, the seed of required test plants species is planted in seedling alms bowl.Using standard soil as cultivation matrix.When plant reaches the 3rd to four leaf periods, herbicide individually or is in combination processed into blade.Each treatment is repeated 4 times.
According to constant weight percentage reagent preparation：1st, halosulfuronmethyl；2nd, pendimethalin；3rd, halosulfuronmethyl+pendimethalin；.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 claims 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 based in " CalculationSynergistic and
Antagonistic Response of Herbicide Combinations”(Weeds
15/1 (1967), S.R.Colby) described in Colby ' s methods determine.
In formula, X be halosulfuronmethyl with certain dosage when alone to the fresh weight inhibition of target weeds.
Y be pendimethalin with certain dosage when alone to the fresh weight inhibition of target weeds.
E0To the theoretical value of target weeds fresh weight inhibition during for halosulfuronmethyl and two kinds of pharmacy mix of pendimethalin.
To the measured value of target weeds fresh weight inhibition when E is halosulfuronmethyl and two kinds of pharmacy mix of pendimethalin.
If the actual control of weeds rate observed in biologic test（E）More than the desired value for using Colby ' s methods to be calculated（E0）, then it represents that summation of the effect of Herbicidal combinations more than each agent effectiveness, it means that composition has synergistic effect.
The Herbicidal combinations of 1 halosulfuronmethyl of table+pendimethalin are to barnyard grass in greenhouse（21 days after）Synergistic activity
The Herbicidal combinations of 2 halosulfuronmethyls of table+pendimethalin are to difformed galingale herb in greenhouse（Cyperus difformis L）（21 days after）Synergistic activity
The Herbicidal combinations of 3 halosulfuronmethyls of table+pendimethalin are to China Sprangletop in greenhouse（21 days after）Synergistic activity
Table 1, table 2, the number of table 3 is it was demonstrated that the herbicide of the composition of halosulfuronmethyl+pendimethalin shows cooperative effect on Weeds distribution.
