Agrochemicals and storage times on soybean seed vigor

Abstract

Abstract: The objective of this work was to investigate the potential physiological damage of the treatment of '97Y07RR' soybean seeds with different pesticides at different storage times, in order to define the optimal period of sowing. The germination rate, the germination speed index, and shoot fresh matter were evaluated. Thiamethoxam did not cause losses in seed vigor with increasing storage time; however, the other agrochemicals caused significant losses. Seed treatment should be performed up to 90 days before sowing.
