Fusarium wilt, caused by Fusarium oxysporum f. sp. vasinfectum, is one of the major diseases of cotton. Preventive methods to manage this disease should be adopted what includes the seed treatment with biocontrol agents as a good alternative. This work aimed to evaluate the efficiency of biological products based on Trichoderma spp. and Bacillus subtilis in the control of Fusarium oxysporum f. sp. vasinfectum (Fov) applied in seeds and seedlings of cotton. The experiment was carried out at the Laboratório de Fitopatologia of the Centro de Ciências Agrárias, of the Universidade Federal de Paraíba (CCA-UFPB), located in the city of Areia, Paraíba - Brazil. The disease transmission of the seeds to the seedlings was evaluated. After the transmission test, cotton seeds of the variety Mocó (Gossypium hirsutum var. Marie-gallante (Watt) Hutch.), BRS 286 and Topázio cultivar (Gossypium hirsutum L.) were submitted to the treatments T1 - Control, T2 - Trichodel® (0,5 mL); T3-Trichodel® (1.0 mL); T4-Trichodel® (1.5 mL); T5-Trichodel® (2.0 mL); T6- Bactel® (2.0 mL); T7-Bactel® (2.5 mL); T8-Bactel® (3.0 mL); T9-Bactel® (3.5 mL) diluted in 100 mL SDW; T10 - Fungicide Captana (240 g / 100 kg of seeds) and inoculated with Fov. The pathogen incidence of the seeds was evaluated seven days after the inoculation (DAI). To evaluate the biological control of Fov in the seedlings, the treated seeds were submitted to the following inoculation methods: 1 - inoculation of the substrate with a pathogen conidia suspension; 2 - immersion of the seeds in the conidia suspension and 3 - direct contact of the seeds with the pathogen mycelium. Twenty-one DAI the disease severity and percentage of seedlings with vascular darkening were evaluated. It was observed a transmission rate of 64.0 to 89.0% of the seeds to the seedlings. Trichodel® reduced the incidence and severity of Fov in the cotton seedlings and was the most efficient product.

SUMMARY: The meteorological data have always served as tools for decision support for agriculture, but data availability and quality are often a problem. This reality is very present in the data acquisition of daily solar radiation (SRAD), due to the process of acquisition of such data requires electronic integrators, sensors, and accurate calibration standards, which are rarely available. The NASA Office of Energy Resources World Forecast and estimated daily data of solar radiation based on satellite observations and atmospheric parameters derived from satellite observations and mathematical models. The data are available for a grid, worldwide, in 1 ° × 1 ° in geographic coordinates. In Brazil, the daily solar radiation data were generated from atmospheric attenuation extraterrestrial radiation (Q0). We compared data from NASA's daily solar radiation (SRADNP) with the data generated and available through the INPE of 18 stations (observed values of daily solar radiation, SRADOB). It was found that the observed versus estimated daily solar radiation showed a good correlation between the models, indicating that the model NASA / POWER is effective to estimate daily radiation data. |
