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 incorporated into the soil, representing negative and positive controls. Stenocarpella concentration in
stalks was assessed using qPCR expressed as cycle threshold number. Sewage sludge, buried
stalks, and stalks retained on the surface showed reduction of pathogen inoculum. Swine manure
and urea did not reduce the quantity of DNA. In the experiment conducted in Lavras, poultry litter
stimulated β-glucosidase, urease and hydrolysis of fluorescein diacetate activities when compared
to the negative control. Sewage sludge, poultry litter, and swine manure increased Ca in the soil
by 44 %, 38 % and 36 %, respectively, in the experiment conducted in Lavras. Poultry litter increased Ntotal three months after application. The results indicate that organic wastes are promising
in improving nutrient content, activity of hydrolysis-related enzymes, but Stenocarpella inoculum
dynamics should be taken into consideration when deciding on the specific organic amendment. MenosThe incorporation of organic matter to the soil not only improves nutrient content,
