VIGOR DE SEMENTES DE SOJA SUBMETIDAS A TRATAMENTO QUÍMICO

Abstract

The present study aimed to verify the isolated effect of insecticides, fungicides and the 171 combination between these in the vigor and germination of soybean seeds. Was 172 conducted in two stages, the first being conducted in a greenhouse in the experimental 173 area of horticulture of the Instituto Federal Goiano - Campus Morrinhos-GO, where the 174 emergency speed index (IVE) of soybean seeds. The second stage was carried out in the 175 laboratory of Provigor seeds, in the municipality of Goiatuba-GO where took place the 176 accelerated aging test of seed for the force. The experiments were conducted in 177 completely randomized design, with 4 repetitions and 9, whose treatments are 178 combinations of insecticides and fungicides for soybean seed treatment in pre-emergence 179 (T1: Imidacloprido e Tiodicarbe + Fludioxonil e Metalaxyl-M; T2: Tiametoxan + 180 Fludioxonil e Metalaxyl-M; T3: Fludioxonil e Metalaxyl-M; T4: Carboxina e Tiram; T5: 181 Imidacloprido e Tiodicarbe; T6: Tiametoxan + Carboxina e Tiram; T7: Imidacloprido e 182 Tiodicarbe + Carboxina e Tiram; T8: Testemunha e T9: Tiametoxan). The application of 183 treatments made possible negative effect on emergence of seedlings and force of the 184 same. The use of seed treatment cannot be considered indicative of force of the seeds and 185 the conditions under which they were subjected in planting.
