Thiamethoxam treated bean seeds performance during storage

Abstract

After sowing, seeds are exposed to the action of soil pests and adverse environmental conditions that can reduce the expression of their physiological potential. A solution to these problems is the seed treatment with insecticides to protect the seeds and seedlings against the action of pests and to promote plant growth. The aim of the experiment was to evaluate the influence of thiamethoxam combined with storage on the physiological performance of bean seeds, IAPAR Siriri cultivar. Seeds were treated with Crusier 350 FS® in doses of 0, 100, 200, 300, 400 and 500 mL 100 kg-1 of seeds, and for evaluation of treatment effect, seeds were submitted to germination and vigor tests (accelerated aging, cold test and emergence in seedbed) at 0, 3, 6, 9 and 12 months after treatment in a completely randomized 6 x 5 factorial design with four replications. Treatment of bean seeds with thiamethoxam doses between 200 and 300 mL 100 kg-1 of seeds allows germination and vigor expression as well as storage potential under controlled conditions, decreasing the rate of germination loss over time.
