Hill Reaction Activity

The susceptibility of sweet pepper (Capsicum annuumL. ‘Keystone Resistant Giant’) and tolerance of hot pepper (Capsicum chinenseL. ‘Bohemian Chili’) to bentazon [3-isopropyl-1H-2,1,3-benzothiadiazin-4(3H)-one 2,2-dioxide] was demonstrated under greenhouse and field conditions. Sweet pepper growth and fruit production were inhibited by foliar applications of bentazon at rates of 0.6 to 6.7 kg ai/ha. Severity of injury increased with application rate. Injury symptoms in sweet pepper were leaf chlorosis, with necrosis and death of shoot apices. Foliar applications of bentazon to hot pepper resulted in little or no injury. Bentazon inhibited Hill reaction activity of isolated chloroplasts from both species to a similar extent, suggesting that selectivity of this compound in hot pepper is not due to resistance at the chloroplast level.

Uno de los problemas fitosanitarios en el cultivo de chile es la mosca blanca, transmisor de begomovirus. Ante la necesidad de alternativas, se planteó el objetivo de evaluar la tolerancia de injertos de <em>Capsicum chinense-Capsicum annuum</em> var. glabriusculum a begomovirus bajo condiciones de campo. Se utilizaron dos materiales criollos para portainjerto (amashito y muela) y chile habanero como injerto (criollo y jaguar). Se empleó la injertación de “púa terminal” y se generaron seis tratamientos. Se registraron cada 10 días las poblaciones de mosca blanca, la incidencia y severidad de la enfermedad, con esta última se calcularon ABCDE, tasa de infección aparente y Yfinal. En etapa de producción, se determinó rendimiento, longitud y diámetro de frutos. A los 130 días después del trasplante, la menor población de mosca blanca, se cuantificó en los tratamientos injertados (muela + habanero jaguar, amashito + habanero jaguar, muela + habanero criollo y amashito + habanero criollo) que osciló entre 5.5 a 14.5 insectos por planta. La mayor incidencia y severidad promedio de virosis fue en habanero jaguar con 100 y 62%. La menor ABCPE, tasa de infección aparente y Yfinal se estimaron en muela + habanero criollo con 746.6 (% por día), 0.005 (% por día) y 23.4%, en su orden; asociado con la fortaleza genética del portainjerto. Los injertos amashito + habanero jaguar, amashito + habanero criollo y muela + habanero criollo mostraron mejor comportamiento agronómico y productividad del cultivo.

Herbicide Metabolism

Similar uptake and translocation patterns were observed in sweet pepper (Capsicum annuumL. ‘Keystone Resistant Giant’) and hot pepper (Capsicum chinenseL. ‘Bohemian Chili’) following foliar applications of14C-bentazon [3-isopropyl-1H-2,1,3-benzothiadiazin-4(3H)-one 2,2-dioxide]. In both species, most of the14C absorbed remained in the treated leaves, with minimal acropetal and basipetal translocation from the application site. A significantly faster rate of herbicide metabolism occurred in hot pepper at 1 and 4 days after application compared to sweet pepper. Two unidentified metabolites of bentazon were isolated from methanol extracts of the two species.
