Efeito da dosagem com fungicida químico e biológico no controle de Rhizoctonia solani em sementes de soja

Abstract

Brazil is a great dimensions country, and soybeans represents one of the most important crops in nearly decades, playing a great responsibility people role for feeding the world and enabling the expansion of “Cerrado” biome. Large areas in monoculture bring challenges with them, such as the management of pests and diseases. Root rot is a disease caused by a soil fungus, and in this context, the objective was to evaluate the efficiency of the doses of chemical and biological fungicides in seeds treatment of two previously inoculated transgenic soybean varieties. The experiment were as conducted in a controlled environment with three replications and four treatments. Seeds were as inoculated using the water restriction method and subsequently treated. The characteristics evaluated were percentage of germination, plant height, number of leaves and green mass of shoots and roots. By analyzing the results obtained, it was concluded that the chemical treatment was more efficient than the others.
