Biological test example
The evaluation of the mixed synergistic effect for applying middle display to two or more herbicidal active components is based in " Calculat
ionSynergistic and Antagonistic Response of Herbicide Combinations”(Weeds 15/
1 (1967), S.R.Colby) described in Colby ' s methods determine.
Calculation formula such as following formula（1）It is shown
……………………………………(1)
Formula（1）Middle X represents control of weeds (%) of the herbicide A under Xg active ingredients/ha dosages,
Y represents control of weeds (%) of the herbicide B under Yg active ingredients/ha dosages,
E represents the expection control of weeds (%) under X+Yg active ingredients/ha dosages.
If the actual control of weeds rate observed in biologic test exceedes what is be calculated using Colby ' s methods
Desired value (E), then it represents that the effect of Synergistic herbicide compositions is more than the summation of each agent effectiveness, it means that composition, which has, to be increased
Effect acts on.
Test method：
Unifacial leaf and dicotyledonous harmful plants are placed in the peat basin (diameter 4cm) equipped with sandy loam, then with soil
Earth covers.Peat basin is maintained in greenhouse under optimum condition.
Cultivation start after about 4 weeks, in the 2 leaf phases to 4 leaf phases handle test plants.In order to further cultivate plant, then
Peat basin is maintained in greenhouse under optimum condition.3 kinds of reagents are prepared according to constant weight percentage：1st, florasulam；
2nd, bentazone；3rd, florasulam+bentazone；Above-mentioned each reagent is diluted with water afterwards, obtains medicament dilution.
The visual score of herbicidal effect 30 days after the treatment.Scoring is with the percentage compared with untreated check plant
Count to carry out.0%=is without activity of weeding, the complete activity of weeding of 100%==kill completely.
