Resumo
Insecticides belonging to neonicotinoids are systemic and can change parameters of plant physiology negatively causing phytotoxicity. Given this, the present study sought to identify the potential phytotoxic effect on seed genotype BRS Aroeira. The work was conducted in a greenhouse on the campus of Santa Helena de Goiás, Goiás State University – UEG (Universidade Estadul de Goiás). Was Recorded the phytotoxic potential of the active ingredient Imidacloprid seed treatment when undiluted. When the product was used without dilution, the insecticide Imidacloprid negatively affected the survival, dry matter accumulation, daily growth rate and the germination period. Therefore, the results of this study revealed that Imidacloprid, when undiluted, is highly detrimental to physiological parameters of quality of cotton seeds.
