[Resumen]: Botrytis cinerea Pers.:Fr. es un hongo patógeno de plantas, tiene forma de vida necrotrófica y es el agente causal de la podredumbre gris. Su forma sexual es el teleomorfo Botryotinia fuckeliana Whetzel, que raras veces se observa. El anamorfo Botrytis cinérea se reproduce asexualmente y forma conidios que provocan la infección primaria en plantas. En este trabajo se ha comparado el efecto fungicida de la bencilaminopurina (BAP) y del pirimetanil (PIRI) en dos aislados con distinta sensibilidad a ciprodinil, un fungicida análogo al pirimetanil. Se realizaron ensayos para estudiar la inhibición del crecimiento del micelio, de la germinación de conidios y del crecimiento del tubo germinativo. Mientras que el pirimetanil inhibió significativamente a Botrytis cinerea en todos los ensayos, la bencilaminopurina solamente lo hizo en algunos casos.

A súa forma sexual é o teleomorfo Botryotinia fuckeliana Whetzel que raras veces se observa. O anamorfo Botrytis cinerea reprodúcese asexualmente e forma conidios que provocan a infección primaria en plantas. Neste traballo comparouse o efecto funxicida da bencilaminopurina (BAP) e do pirimetanil (PIRI) en dous illados con distinta sensibilidade a ciprodinil, un funxicida análogo ao pirimetanil. Realizáronse ensaios para estudar a inhibición do crecemento do micelio, da xerminación de conidios e do crecemento do tubo xerminativo. Mentres que o pirimetanilinhibiu significativamente a Botrytis cinerea en todos os ensaios, a bencilaminopurina soamente o fixo nalgúns casos.
[Abstract]: Botrytis cinerea Pers.:Fr.is a plant pathogenic fungus with a necrotroph lifestyle and is the causal agent of grey mould. Its sexual form is the teleomorph Botryotinia fuckeliana Whetzel, which is rarely observed. The reproduction of anamorphic Botrytis cinerea is asexual, forming conidia that cause the primary infection in plants. In this study we compared the fungicide effect of benzylaminopurine (BAP) and pyrimethanil (PIRI) in two isolates with different sensitivity to cyprodinil, a fungicide analogue of pyrimethanil. Assays were carried out to study the inhibition of mycelial growth, conidia germination, and germ tube growth. While pyrimethanil significantly inhibited Botrytis cinerea in all assays, benzylaminopurine only did it in some cases.
