Uso de agroquímicos como posible medida de control de la "escoba de bruja" (Crinipellis perniciosa) del cacao

An experiment was carried out to find an alternative for the control of Crinipellis perniciosa. The systemic fungicides pyracarbolid, oxicarboxin, triadimephon and a mineral oil were evaluated under field conditions. Three types of brooms were sprayed twice during the highest peak of sporulation. A...

The systemic fungicides pyracarbolid, oxicarboxin, triadimephon and a mineral oil were evaluated under field conditions. Three types of brooms were sprayed twice during the highest peak of sporulation. A high inhibition of sporulation was observed with mineral oil alone or mixed with fungicides. Good sporulation inhibition was also observed when oxicarboxin was applied in water. Sporulation of brooms on trees was lower in those sprayed with oil or fungicides in oil. Green and dry brooms detached from trees and hugh up under the canopy, produced significantly fewer basidiocarps than the control. An integrated program of control could be used taking in consideration the fungicide effectivity, spray cover and disease cycle. Buscando alternativas de control contra Crinipellis perniciosa, los fungicidas sistémicos pyracarbolid, oxicarboxin, triadimephon y el aceite agricola fueron evaluados baja condiciones de campo. Dos aspersiones de fungicida se aplicaron a tres tipos de escobas durante Ia época de mayor esporulación. Una alta inhibición en Ia formación de basidiocarpos se obtuvo con el aceite solo o en cualquiera de sus mezclas. De los fungicidas aplicados en agua, el oxicarboxin presentó buen cornportamiento. Las escobas verdes adheridas a los árboles fueron eficientemente inhibidas por el aceite o sus mezclas. Las escobas verdes y secas removidas de los árboles presentaron significativamente menos basidiocarpos que el control. La efectividad del fungicida, Ia cobertura y el ciclo del hongo son discutidos dentro de un contexto de control integrado de Ia enfermedad.
