Performance of soybean seeds treated with insecticides and subjected to different storage periods

Abstract

This study aimed to evaluate the physiological performance of soybean seeds stored under treatment with insecticides. The seeds of the cultivar M-SOY 6101 were subjected to four storage periods (0, 3, 5 and 7 days after treatment) and seven insecticides. The experimental design was completely  randomized in a 4 x 7 factorial scheme with four replications. The seeds were treated with the insecticides thiamethoxam, fipronil, imidacloprid,
imidacloprid + thiodicarb, acephate and a control without treatment. The analyzed variables were: germination, emergence speed, root and seedling length, dry matter reduction and normal seedlings percentage in the accelerated aging test. The application of the insecticides acephate, carbofuran, imidacloprid and imidacloprid + thiodicarb is harmful to the physiological quality of soybean seeds, cultivar M-SOY 6101, stored for a period up to seven days. Soybean seeds treated with the insecticides thiamethoxam and fipronil reached proper germination and vigor levels, regardless of the storage  period.
