| ABSTRACT: The incorporation of organic matter to the soil not only improves nutrient content, but also reduces the survival of Stenocarpella, the causal agent of stalk rot, Diplodia ear rot, and grey leaf spot, in maize stubble. We evaluated the effect of organic waste incorporation on Stenocarpella survival in maize stalks, the activity of suppressiveness-related enzymes, and nutrient contents. We conducted the assays in the municipalities of Lavras and Sete Lagoas, Minas Gerais State, Brazil. Maize stalks infested with Stenocarpella were kept in field conditions for three months after poultry litter, swine manure, fish hydrolysate, compost sewage sludge, and urea application. Infested stalks, without residue amendment, were kept on surface or... |

| This study aimed to evaluate the production and germination of Stenocarpella maydis pycnidiospores under in vitro conditions as affected by substrate composition (sorghum, wheat, black oat or barley), light regime (continuous dark, 12-h light dark-1 or continuous light conditions), and incubation temperature (21, 24, 27, 30 or 33ºC). Each substrate (20 g of grain) was soaked in 100 mL of water for 24h and sterilized twice for 20 min at 127ºC. Three plugs (5 mm diameter) of a single-spored culture of S. maydis were used as inocula for each substrate. Assessments of pycnidiospore production per gram of grain and percent germination were made 14 days after inoculation. Barley, black oat or wheat grains were the best substrates for the mass production of S.... |
