| Corn stalk rot – CSR is a complex disease caused by many organisms, among fungi and bacteria, due to interactions between soil- or residue-borne organisms and environmental stresses acting on the plant. Studies have been done to understand this complex to find ways to minimize losses due to the disease. The main objective of this work was to assess CSR incidence after different winter crop rotations under conventional and no tillage conditions. A winter crop rotation experiment under no till and conventional tillage has been carried out at Pato Branco Iapar Exp. Sta. since 1986, and corn hybrid DKB 240 PRO was planted in all plots at Spring. There were 10 winter alternatives and fallow and clean fallow, totaling 12 treatments, planted in conventional and... |

| Potato late blight – PLB is the most destructive foliar fungal disease for the crop in Southern Brazil. Organic farmers are in the urge to find ways to minimize losses due to the disease. Thus, the main objective of this study was to evaluate the effect of mulching on potato crop on late blight epidemic reduction using soil mulching. Two experiments were installed for the spring planting, at Lapa, PR. Treatments were with mulching (60 t/ha fresh weight, plant cover composition was mainly of ryegrass, oats, mixed with wild radish) and no mulching. Cultivars Ágata (susceptible) and BRS Ana (moderately resistant) were used in each experiment. Randomized complete blocks with 4 reps was the experimental design. PLB severity was weekly assessed visually on plots... |
