Abstract


The use of quality seeds is an important factor for crop establishment. The aim of this study was to evaluate the physical and physiological quality of wheat seeds submitted three different treatments using mixes of micronutrients including zinc: micronutrient 1 (1% Mn; 0.1% Mo; 10% Zn); micronutrient 2 (0.3% B; 0.3% Co; 3% Zn) and no micronutrient combined with polymer (Colorseed He), blend of fungicide carboxin+thiram (Vitavax® Thiram 200 SC) + insecticide thiamethoxam (Cruiser® 350 FS) and combination of treatments polymer Colorseed He + fungicide Vitavax® Thiram 200 SC + insecticide Cruiser® 350 FS. After treatment, was held at intervals of 60 days, germination tests, accelerated aging and moisture content determination of the wheat seed stored under uncontrolled conditions for a period of 240 days. Untreated seeds and treated wheat seeds with polymer, carboxin+thiram + tiamethoxam, polymer + carboxin+thiram + tiamethoxam, associate or not with micronutrients (1%Mn; 0.1%Mo; 10%Zn or 0.3%B; 0.3%Co; 3%Zn) maintains germination during storage for 180 days, under uncontrolled conditions. The seed treatment does not alter the moisture content of seeds.
