Test treatments of a nuclear polyhedrosis virus (NPV) and the insecticides carbaryl and methomyl were applied to naturally occurring field populations of the velvetbean caterpillar (VBC), Anticarsia gemmatalis Hubner, on soybean to determine their efficacy in reducing VBC larval populations and their effect on naturally occurring epizootics of the entomogenous fungus Nomuraea rileyi (Farlow) Samson. Virus treatments consisted of 30, 58, 58 plus 0.5 lbs of benomyl, and 115 larval equivalents (LE)/acre. Insecticde treatments consisted of carbaryl at 0.25, 0.06, 0.03, and 0.003 lb of active ingredients (AI)/acre and methomyl at 0.25, 0.06, 0.03, and 0.006 lb AI/acre. Laboratory studies were also conducted to determine efficacy of the virus and its persistence inthe field. All viral doses were effective in suppressing VBC populations below damaging levels even at 19 days after one application of NPV. Most larval mortality occurred at 6, 7, and 8 days spraying, but laboratory tests revealed that the infected larvae ceased feeding after the 4th day. Tests on viral persistence of activity in the field showed that the NPV retained 65% to 70% of its original activity 7 days after. |

The viticulture in the semiarid region of Brazil stands out in the country due to the expansion of its cultivated area and increased production, especially in the sub-mid São Francisco Valley. However, the supplying of water and an efficient replacement of nutrients to the soil are essential for these crops, due to the intrinsic climatic conditions of this region, such as low rainfall and high evapotranspiration. This study aimed at evaluating the physiological characteristics of ?Itália? grapevine (Vitis vinifera L.) under irrigation and fertilization management. The experiment was conducted in a randomized block design, with four replications, in a split-plot arrangement, with four irrigation water depths (0.75, 1.00, 1.25 and 1.5 times the crop coefficient) in the plots and four fertilizer rates (100 %, 75 %, 50 % and 25 %, based on the recommended fertilizer rates for this crop) in the subplots, with addition of organic compounds. The leaf water potential, leaf chlorophyll content, relative water content, photosynthesis, stomatal conductance, internal CO2 partial pressure, leaf temperature and biomass accumulation in the berries were evaluated. The highest leaf chlorophyll contents were found in treatments with fertilizer rates of 70-85 %. Stomatal conductance decreased with the increasing irrigation water depths, thus reducing the internal CO2 partial pressure and increasing the leaf temperature and air vapor pressure deficit. The reduction of 25 % in the conventional fertilization and irrigation of 135 % of the recommended coefficient resulted in the highest average weight of berries. The highest yields were obtained with the lowest irrigation water depths and fertilizer rates of 50-65 %.
