Abstract
Cotton plants were grown in sand cultures containing serial amounts of Thimet in the greenhouse. Slight (10 ppm) to severe (500 ppm) necrotic flecking of the leaves occurred and was correlated with levels of Thimet in the substrate. As compared to control plants, the higher rates of the insecticide caused reductions in plant weights and boll sizes, whereas no adverse effects resulted at the lowest level (10 ppm). Carbohydrates and P accumulated in young plants although soluble and protein nitrogen decreased. Harvested seeds from plants at all treatment levels had equally high germination, approximately 92%.This publication has 0 references indexed in Scilit:
