EFFICACY OF BENOMYL+CAPTAN AND BC1000 IN THE CONTROL OF BOTRYTIS CINEREA AND ALTERNARIA ALTERNATA IN HIGHBUSH BLUEBERRY (VACCINUM CORYMBOSUM) CV. BLUEJAY

EFFICACY OF BENOMYL+CAPTAN AND BC1000 IN THE CONTROL OF BOTRYTIS CINEREA AND ALTERNARIA ALTERNATA IN HIGHBUSH BLUEBERRY (VACCINUM CORYMBOSUM) CV. BLUEJAY

  It was determined the phenological stage of higher susceptibility, incidence and control of Botrytis cinerea and Alternaria alternata in three year old plants of highbush Blueberry cv. Blejay. The fungicides benomyl+captan (45g+144g i.a/HL) and BC1000 (150 c.c. i.a./HL) were evaluated. The treatments consisted of 1, 2, 3 and 4 aplications of BC1000 between the beginniug of flowering and maturity; and a comparative experiment between benomyl+captan and BC1000 with 1, 2, 3 aplications in differents phenological stage between full flowering and maturity. The fruits were mantained in a cold chamber (0°; 95% H.R) for a period of 14 days and in laboratory conditions (average of 18°; 60% H.R), for 7 days. The incidence of fungi was evaluated to the harvested crop and until the end of the storage period. Phenological stages of more susceptibiliíy to B.cinerea were flower-clot and maturity, while no such stages were accurately established for A.alternata. BC1000 had a more effcctive control over B.cinerea aplicated in flower-clot and maturity, while flowering aplications were no effective. BC1000 in field conditions did not control A.alternata significatively. Benomyl+captan was more effective than BC1000 over B.cinerea with three aplications from full flowering to maturity, and there were no differences between fungicides with two aplications (flower-clot and maturity) and one in maturity.

Fueron evaluados benomilo+captan (45g+144g i.a./HL) y BC1000 (150 c.c. i.a./HL). Los tratamientos consistieron en 1, 2, 3 y 4 aplicaciones de BC1000 entre inicio de floración y madurez; y ensayos comparativos entre benomilo+captan y BC1000 con 1, 2 y 3 aplicaciones en diferentes estados fenológicos entre plena floración y madurez. La fruta cosechada fue mantenida en cámara de frío (0°C; 95% H.R.) por 14 días y en condiciones de laboratorio (promedio de 18°C; 60% H.R.), por 7 días. La incidencia de los hongos fue evaluada a la cosecha y al cumplirse el período de almacenamiento. Los estados fenológicos de mayor susceptibilidad a B.cinerea fueron flor-cuaja y madurez; mientras que para A.alternata no se estableció con exactitud dichos estados. BC1000 ejerció un control efectivo sobre B.cinerea aplicado en flor-cuaja y madurez, en tanto que aplicaciones en floración no fueron efectivas. BC1000 en condiciones de campo no controló significativamente a A.alternata. Benomilo+captan fue más efectivo que BC 1000 sobre B.cinerea con tres aplicaciones desde plena floración a madurez, y no hubo diferencias entre los fungicidas con dos aplicaciones (flor-cuaja y madurez) y una en madurez.   Facultad de Ciencias Agrarias.
