Productivity of Sugar Beet Damaged by Hormone-Like Herbicidesin Sublethal and Thinning Doses
In many year field experiments, there was investigated influence of hormone-like herbicide solutions’ residual left in a sprayer tank after treatment of grain-crops on productivity of sugar beet being treated with Betanal Expert OF. It was shown that small doses of hormone-like herbicides considerably inhibited plant mass increasing and thinned sugar beet plant stand. Presence of Esteron, Dikamba and Agritoks impurities, when applying herbicides of Betanal group, increased the mixture toxicity of the crop plants 1.4–1.9-fold. Data on decrease of sugar beet productivity indices depending on a dose of the hormone-like herbicide residual in the solution with Betanal Expert OF are presented.
