Different responses of weed to reduced bentazone doses

Original language description

A small-plot field trial was carried out to evaluate the efficacy of reduced doses of bentazone on Fallopia convolvulus and Amaranthus retroflexus in the years 2005 -- 2008. Three various doses of bentazone (960 -- 720 -- 480 g, included in herbicide Basagran Super) were applied at the third leaf stage of growth in Amaranthus retroflexus, and at the seventh leaf stage of growth in Fallopia convolvulus. Herbicide efficacy was assessed by PS1 meter 1, 2, 3, and 4 days after the treatment. This instrumentmeasures the changes in absorbance induced by light and shows the degree of damage of photosynthetic apparatus of weeds. In case of Amaranthus retroflexus, the efficacy of 480 g dose of bentazone per hectare was 90--95 %. On the other hand, in the case of Fallopia convolvulus the efficacy of the same bentazone dose was under 85 %. Two days after the treatment, PS1 values declined as a consequence of regeneration and subsequent new growth of Fallopia convolvulus. This decline of PS1 value
