| Avaliou-se a erradicação de escleródios de Sclerotium rolfsii em diferentes temperaturas e umidades do substrato. Testaram-se umidades de 5, 6, 9 e 11 (equivalentes a -5, -3, -1 e -1/3 Bar) e mais 0 e 18% de umidade. As temperaturas testadas foram 40, 48, 52 e 58°C, no tempo de 30 min., seguidos de resfriamento em balcão, em condições de laboratório. Avaliou-se a germinação em meio BDA salino. A 0% de umidade do substrato, nenhuma temperatura foi eficiente na inativação dos escleródios. Para todas as outras umidades testadas, porém, os escleródios foram erradicados em temperaturas acima de 52°C. De todas as quatro temperaturas testadas, apenas a menor (40°C) não inativou os escleródios do patógeno. A 48°C, a erradicação dos... |

| SUMMARY Temperature modification in soil of plastic greenhouse caused by solarization was measured during the summer in the Subtropical Central Region of the Rio Grande do Sul State, Brazil. The experiment was carried out in a 10m x 25m greenhouse covered with low density transparent polyethylene (PE). Four 6m x 4m plots were mulched with 100µm thickness PE sheets, from December 12, 1992 to March 7, 1993. Four other plots (same size) without the cover were used as control (bare soil). Results indicated that solarization incrased the maximum soil temperature. The average was 11.9, 10.8, 9.8, and 8.6°C over uncovered control soil at 2, 5, 10, and 20cm depth, respectively. The soil temperature reached values of up to 54.4°C at 2cm and 50.2°C at 5cm depth.... |

| ABSTRACT Weed control is consider the major obstacle for the growers in the organic farming. Lower plant productivity in organic farming mainly related to the poor weed control. It is widely known, in most cases, that losses caused by weeds exceeded the losses from any category of agricultural pests. Under water-stress condition, weeds can reduce crop yields more than 50% through moisture competition alone. In the light of the environmental and toxicological problems created by herbicides, it has become necessary to develop the safety methods for controlling weeds. Soil Solarization, Mulching, Biodegradable Mulch, Natural Herbicides, Hot Water, and Agronomic Practices have been successfully adopted in many countries as safe methods for controlling weeds in... |
