The nucleopolyhedrovirus of A. gemmatalis (AgMNPV) is being employed annually on about 2.0 million ha of soybean in Brazil. Up to 2003 all production were made in the field for processing and formulation by private companies. Improvements on laboratory production procedures, presented in SIP 2003, resulted in a final product of much better quality and at a cost competitive with those of chemical insecticides. The procedures were further adjusted through the implementation in one of the companies (COODETEC) of a "Pilot Laboratory" for AgMNPV production (presented in SIP 2004). We now report the implementation of laboratory facilities at COODETEC for commercial production of the AgMNPV. These were inaugurated in November/2004 and consist of two independent laboratories: one for continuous insect production (700 m2) and another for virus production (750 m2). In the former, the insects are reared up adults, for egg collection and rearing the larvae up to the fourth instar in 500-ml cardboard cups (avg. of 300-350 larvae/cup). Daily, 3% of these larvae are placed in plastic boxes (30x35x12cm) containing diet and vermiculite for obtaining pupae to maintain the colony. The remaining larvae (97%) are transfered to the virus production laboratory, where they are placed in plastic boxes containing AgMNPV contaminated diet. Dead larvae are collected, processed and formulated as a bioinsecticide (COOPERVIRUS PM). COODETEC is expanding its AgMNPV production to reach its maximum capacity, which will involve 45 employees and inoculation of 600,000 larvae/day to produce virus to treat aproximately 1.4 million hectares ofsoybean/year.

Due to the difficulty of estimating water percolation in unsaturated soils, the purpose of this study was to estimate water percolation based on time-domain reflectometry (TDR). In two drainage lysimeters with different soil textures TDR probes were installed, forming a water monitoring system consisting of different numbers of probes. The soils were saturated and covered with plastic to prevent evaporation. Tests of internal drainage were carried out using a TDR 100 unit with constant dielectric readings (every 15 min). To test the consistency of TDRestimated percolation levels in comparison with the observed leachate levels in the drainage lysimeters, the combined null hypothesis was tested at 5 % probability. A higher number of probes in the water monitoring system resulted in an approximation of the percolation levels estimated from TDR-based moisture data to the levels measured by lysimeters. The definition of the number of probes required for water monitoring to estimate water percolation by TDR depends on the soil physical properties. For sandy clay soils, three batteries with four probes installed at depths of 0.20, 0.40, 0.60, and 0.80 m, at a distance of 0.20, 0.40 and 0.6 m from the center of lysimeters were sufficient to estimate percolation levels equivalent to the observed. In the sandy loam soils, the observed and predicted percolation levels were not equivalent even when using four batteries with four probes each, at depths of 0.20, 0.40, 0.60, and 0.80 m. |
