Biological test example
The evaluation of the mixed potentiation executing middle display of two or more herbicidal active components is based on what Colby ' the s method described in " CalculationSynergisticandAntagonisticResponseofHerbicide Combinations " (Weeds15/1 (1967), S.R.Colby) was determined.
Shown in computing formula such as following formula (1)
……………………………………(1)
In formula (1), X represents herbicide A control of weeds (%) under Xg effective ingredient/ha consumption,
Y represents herbicide B control of weeds (%) under Yg effective ingredient/ha consumption,
E represents the expection control of weeds (%) under X+Yg effective ingredient/ha consumption.
If the actual control of weeds rate observed in biologic test exceedes the use calculated desired value of Colby ' s method (E), then represent the effect summation more than each agent effectiveness of Synergistic herbicide compositions, it means that compositions has potentiation.
Test method:
Unifacial leaf and dicotyledonous harmful plants are placed in the peat basin (diameter 4cm) equipped with sandy loam, then cover with soil.Peat basin is maintained in greenhouse under optimum condition.
Cultivation starts latter about 4 weeks, processes test plants in 2 leaf phases to 4 leaf phases.In order to cultivate plant further, subsequently peat basin is maintained in greenhouse under optimum condition.3 kinds of reagent are prepared: 1, florasulam according to constant weight percentage ratio;2, bentazone;3, florasulam+bentazone;Afterwards by above-mentioned each reagent dilute with water, it is thus achieved that medicament diluent.
The visual score of herbicidal effect 30 days after the treatment.Scoring is to carry out with the percent compared with untreated check plant.0%=without activity of weeding, 100%=activity of weeding completely=kill completely.
