Abstract

The study was conducted in the experimental area of the Department of Agronomy -- Universidade Estadual do Centro Oeste - UNICENTRO, in Guarapuava-PR/ Brazil. The objective was to assess the additives effects of the fungicides methiram pyraclotrobin on the plant development and cultivation of potatoes. We carried out the experiment in completely randomized design with five treatments and four repetitions, of which the T1 is the control with fluazinam, T2, T3, T4, T5 are treatments with different doses of methiram pyraclotrobin in the planting furrow and ridging. It was found that the parameters number of leaves and leaf area index are benefited by the application of methiram (2.75 kg i.a. ha-1) pyraclostrobin (0.25 kg i.a. ha-1) applied in the ridging or divided in the furrow and in the ridging. This result was similar to tubers production, that in addition don´t presented differences in the classification in relation to the diameter.
