Qualidade fisiológica de sementes de soja e milho tratadas com produtos de referência e equivalentes

Abstract

The main objective was to find differences between seed treatment products with reference and equivalent products on soybean and corn seeds. Seed where tested right after treating and 60 days after storage. The treatments and the respective doses for 100 kilograms of seeds, were as follows for soybean: 1) control; 2) imidacloprid 60FS Gaucho® (500 mL); 3) equivalent imidacloprid (500 mL); 4) Thiodicarb +Imidacloprid Crop Star® (200 mL); 5) equivalent Thiodicarb + Imidacloprid (200 mL). For corn seeds the tratments were: 1) control; 2) imidacloprid 60FS Gaucho® (300 mL); 3) equivalent imidacloprid (300 mL); 4) Thiodicarb +Imidacloprid Crop Star® (350 mL); 5) equivalent Thiodicarb+ Imidacloprid (350 mL). The analyses were germination, accelerated aging test in soybean and cold test for corn. The results allowed the following conclusions: 1- there are significant differences between reference and equivalent seed treatments, and 2- The storage increases the injury of the equivalent seed treatments.
