Effect of the storage of soybean seeds treated with agrochemicals on the physiological quality and on the seedlings morphology
Abstract
Seed treatment is the most efficient technique for controlling pests and pathogens that can influence the initial development of the crop. However, storing treated seeds may damage the physiological quality. Thus, the objective of this study was to evaluate the influence of storage on the physiological quality of treated soybean seeds and on the morphology of soybean seedlings. The treatments were carried out with Fludioxonil, Imidacloprid and Anthranilic Diamide, in the dosage of 200, 150 and 100 mL of the commercial product 100 kg of seeds, respectively, from the cultivar BRSMG752S. The experimental designs used were randomized blocks (greenhouse) and completely randomized (laboratory), in a simple factorial 4x4scheme, with 4 sowing times (30, 20, 10 and 0 days after treatments) and 4 treatments (3 products and untreated seeds) with 4 repetitions. The treatment of soybean seeds with Anthranilic Diamide submitted to different storage periods was the one with the closest physiological quality to the treatment without application of agrochemicals. The soybean seeds treated with Imidacloprid showed a reduction in physiological quality with the storage time, reduction (in general) in the root length and presented a lower seedling length at 20 days of storage.
