In vitro test for selectivity of soil herbicide Pelikan 50SC to winter forage pea
Svetla Yancheva, Maya Dimitrova, Hristina Cheradjieva
Abstract: Difluphenican 500 g/l). Due to the lack of data for herbicide application in pea, the concentrations of 10, 15, 20 and 25 ml/da have been studied in our experiments. Investigation indexes of germination and growth characteristics of the seeds were evaluated from day 3 to 28 during in vitro culture. Recommended for bean and sunflower working dose of the herbicide 25 ml/da was phytotoxic for studied pea cultivars and resulted in inhibiting germination to day 14 in cv. № 11 while in cv. Mir the germination was decreased with 10%. The effect herbicide in all studied doses was expressed by blocking of the chlorophyll synthesis and growth inhibition of both cultivars. There was strong genotype dependence – cv. № 11 showed higher sensitivity to the herbicide, compared with cv. Mir.
