Swine wastewater (SWW) is a residue from pig farming that presents a high load of nutrients and organic matter. The appliance of organic matter in soil alters the microbial dynamic and may suppress soilborn phytopathogens. This study aimed at evaluating the inhibition on mycelial growth of Sclerotinia sclerotiorum and Sclerotium rolfsii in vitro under SWW doses. Hereupon, three kilograms of a soil classified as red dystroferric latosol was collected and sieved. Half of it was autoclaved. SWW was incorporated at doses of 0 mL, 2.5 mL, 5 mL, 10 mL and 20 mL in both soil conditions, autoclaved and not autoclaved. Afterwards, 130 grams of each soil was separately put into Petri plates above what a thin layer (≅ 5 mL) of Water-Agar (2%) medium was carefully spread over. Above this agar layer, one disk (6 mm diameter) of pure mycelium from each fungal grown in Potato Dextrose Agar medium was individually placed on the center of each plate. Daily evaluations on mycelial growth measuring were taken and ended when mycelium in control plates (without SWW addition) reached plate borders. Results indicated that in autoclaved soil condition, the inhibition was proportional to the dose, what is to say that the higher the dose the less the mycelial growth. In not autoclaved soil there was no significant difference among treatments, suggesting stimuli on suppression effect for both pathogens caused by SWW. In addition, the confirmed potential of SWW as a suppressor of S. sclerotiorum and S. rolfsii leads to promising investigations on other phytopathogens hard to control.

“…As alterações na química do solo são manifestadas pela habilidade para interagir com metais, óxidos e hidróxidos metálicos e pode atuar como depósito de nitrogênio, fósforo e enxofre no solo (SCHNITZER, 1991). A ação biológica, dentre outras funções, está relacionada ao menor ataque de microorganismos fitopatogênicos, podendo atuar diretamente pela produção de compostos químicos ou indiretamente, favorecendo o aumento da população dos antagonistas (MORALES et al, 2007).…”

ResumoO trabalho teve como objetivo avaliar a produtividade, a emissão de estolhos e o teor de sólidos solúveis dos frutos de morangueiro, em função da adubação com esterco de bovino complementar à adubação química, em cultivo protegido, na região Centro-Sul do Paraná. O delineamento experimental empregado foi em blocos casualizados com três repetições, com os tratamentos dispostos em esquema fatorial 4 x 4, compreendendo quatro cultivares (Oso Grande, Sweet Charlie, Dover e Camarosa) e quatro doses de adubação orgânica com esterco (0, 30, 60 e 90 t ha-1). As cultivares Camarosa e Oso Grande tiveram incremento na produtividade com as doses intermediárias, mas reduziram sua produção na dose máxima. A produtividade da cultivar Dover foi reduzida linearmente com o aumento das doses, provavelmente devido ao aumento no número de estolhos emitidos. A cultivar Sweet Charlie

“…These compounds were responsible for reducing the damping-off caused by R. solani in the beetroots of the present study when the highest SM doses were added to the soil, particularly soil showing pH of 7 (Figures 1 and 2; Table 3). Antifungal activity of SM was also reported against the pathogens Verticillium dahlia Kleb (4, 5), Sclerotium rolfsii Sacc (16) and Pythium aphanidermatum (Edson) Fitzp (15).…”

The aim of this study was to evaluate the effect of swine manure (SM) doses applied to soils showing pH of 4.8 and 7.2 on the control of damping-off in beetroot seedlings caused by Rhizoctonia solani. To set the trial, plastic bags were filled with 4 kg soil (pH levels of 4.8 and 7.2) and 15 g R. solani inoculum kg soil-1. This mixture was moistened, homogenized and kept in a greenhouse for seven days. Following this period, SM doses (0, 5, 10, 15 and 20%) were incorporated into the bags, which were again stored in a greenhouse. After seven days, part of the soil from each plastic bag was separately placed into 16 cells of a 128-cell polystyrene tray, and two beetroot seeds were sown per cell. Seedling emergence and damping-off were evaluated for 21 consecutive days. The other part of the soil was used for microbial activity quantification based on the CO2 release method at 7, 14 and 21 days. The trial was conducted in a completely randomized design, with four replicates per treatment, and repeated twice. All tested SM doses reduced the number of damped-off beetroot seedlings in both trials, and the greatest disease control was provided by treatments that had SM doses of 15% and 20% applied to soil showing pH level of 7.2. In addition, regardless of the pH level, all tested SM doses increased soil microbial activity.
