Effect of treatment with foliar herbicides on common winter wheat cultivar Dragana

Zornitsa Petrova

Abstract: The aim of this investigation was to determine the effect of the treatment with foliar herbicides on basic biometrical parameters of spike in common winter wheat cultivar Dragana. The investigations were carried out during 2015-2016 at Dobrudzha Agricultural Institute – General Toshevo (DAI). The following herbicides were used: Derby super WG (33 g/ha), Secator ОD (100 ml/ha), Ergon WG (50 g/ha), Granstar super 50SG (40g/ha), Lintur 70WG (150g/ha) and Mustang 306,25СК (800ml/ha) from the group of sulfunylureas with various mechanism of
action. The preparations were applied at three doses – optimal, double and quadruple, at stage 29 (according to Zadoks) of common winter wheat cultivars Dragana. These were the followed biometrical parameters of wheat spike: length of spike (cm), number of spikelets per spike, number of grains per spike, weight of grain per spike (g) and 1000 grains weight (g). The dose of treatment with the set of herbicides has no significant effect on biometrical parameters of the spike in cultivar Dragana.
