Abstract
ABSTRACT Treatments with pyraclostrobin, a fungicide from the strobilurin chemical group, have induced physiological effects in several plants, which may influence their productivity. In this study, two experiments were carried out to study the effect of a commercial product containing pyraclostrobin + metiram on productivity and virus dissemination in potato cultivars. The first experiment was carried out in Maria da Fé-MG, applying different combinations of the product via furrow at planting and via foliar application, in post-emergence, using the cultivar Cupido and two fertilizer levels: 2,500 kg/ha and 3,500 kg/ha of NPK in the formulation 4:14:8. In the second experiment, eight French potato cultivars were tested in São Gonçalo do Sapucaí-MG, with applications of the fungicide via furrow and via foliar application. An interaction between the fertilizers and cultivars with the types of fungicide treatments used was observed. There was a significant increase of 13.6% in the production of the treated potato cv. Cupido, when the fungicide was applied in the furrow and the NPK level was 2,500 kg/ha. The production of all eight cultivars tested was higher in the treated plots, and the greatest productivity gain was 28% in cv. Eole. In both experiments, pyraclostrobin did not affect the spread of the virus in the field. This study showed that pyraclostrobin has the potential to increase potato productivity and reduce fertilizer use. However, the best treatment and the best fertilizer level should be determined for each cultivar, since the cultivars used responded differently to the same treatments.
