Monitoramento do agente causal da ferrugem asiática via coletor de esporos e seu efeito no controle químico

Abstract

Currently, the number of applications for the control of soybean rust, comes also raising grain production costs, in addition to high production costs, the impact environment also stands out. The high number of applications can be characterized by a smaller amount of information to help the producer and technicians at the time of taking of decision. Therefore, in this work, information will be generated for farmers, technicians agronomic and agronomic methods for decision making at the time of chemical control of Asian rust on soybeans, contributing to the reduction in the number of fungicide applications maintaining productivity and costs. For this application reduction will be monitoring of the arrival of Asian rust spores in the field was carried out, through Use spore collectors by the Paraná Rural Development Institute (IDR-Paraná). Applications of fungicides will be carried out only after the detection of spores on the microscope slide do not have collectors. The experiment will also scheduled application, which is currently used in the municipality of Pato Branco, Paraná (PR), and will be performed as comparisons. The addition of applications contributes to the farmer a lower amount of spending on fungicides, less exposure of the applicator to agrochemicals, and less environmental impact, due to the reduction in the application of fungicides in the environment.
