Chwedoruk, Andrzej | Domańska, Helena
The possibility to decrease herbicide doses without reducing their weed controlling effectiveness was investigated in two microplots and one field experiment. The following herbicides were used: atrazine, mixture of atrazine with terbutrine, MCPA + MCPP, MCPA + dikamba, desmedipham and phenmedipham (Betanal 31, 32 or 37). They were combined with one or several of the following adjuvants: parafinic oil, refuse product of rape oil rafination, oil mixture from the Institute of Organic Chemistry Industry (IPO-Warsaw), surfactant Rokafenol N-1O, mineral oil Nr 8 (Aviol). It was shown that the doses of herbicides could be lowered by 30-50% without loosing their phytotoxic effect on weeds due to addition of adjuvants. The mineral oil 8 was very active in a mixture with Betanal 37 and was completly non toxic toward sugar beets. The oil mixture from IPO and Rokafenol N-10 were very active in mixtures with atrazine or atraizine with terbutrine.
