The following examples explanation present invention
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, the chlorine sodium of 2 first 4；3rd, the different monooctyl ester of the chlorine of 2 first 4；4th, the chlorine sodium of the first of halosulfuronmethyl+2 4；5th, the different monooctyl ester of the chlorine of the first of halosulfuronmethyl+2 4.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 the chlorine sodium of 2 first 4 or the different monooctyl ester of the chlorine of 2 first 4 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 the chlorine sodium of 2 first 4 or the different two kinds of pharmacy mix of monooctyl ester of the chlorine of 2 first 4.
To the measured value of target weeds fresh weight inhibition when E is halosulfuronmethyl and the chlorine sodium of 2 first 4 or the chlorine of 2 first 4 different two kinds of pharmacy mix of monooctyl ester.
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 the chlorine sodium of+2 first of 1 halosulfuronmethyl of table 4 or the different monooctyl ester of the chlorine of 2 first 4 are to barnyard grass in greenhouse（21 days after）Synergistic activity
The Herbicidal combinations of the chlorine sodium of+2 first of 2 halosulfuronmethyl of table 4 or the different monooctyl ester of the chlorine of 2 first 4 are to yellow nut nutgrass flatsedge in greenhouse（21 days after）Synergistic activity
The Herbicidal combinations of the chlorine sodium of+2 first of 3 halosulfuronmethyl of table 4 or the different monooctyl ester of the chlorine of 2 first 4 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 chlorine of the first of halosulfuronmethyl+2 4 or derivatives thereof shows cooperative effect on Weeds distribution.
