Abstract
Springtails and mites have been found consistently in acid scab lesions and studies have shown that these arthropods carryStreptomyces spp. both on and in their bodies. Tests with several soil-applied, systemic insecticides have shown significant control of acid scab despite having little effect on the acid scab pathogen in culture. Diazinon, a long residual insecticide, gave acid scab control as good as the best fungicides thus far tested as seed or soil treatments. This insecticide also was found to be almost nontoxic to the acid scab pathogen. We suggest that soil arthropods appear to be a factor in acid scab development and present circumstantial evidence suggestive of their involvement in all potato scab development.
Resumen
Se ha encontrada en forma consistente la ocurrencia de colémbolos y ácaros en las lesiones de la sarna ácida y los estudios han demostrado que estos artrópodos llevan elStreptomyces spp. tanto sobre, como dentro de sus cuerpos. Ensayos con varios insecticidas sistémicos aplicados al suelo han dado un control significativo de la sarna ácida a pesar de tener sólo un pequeño efecto contra el patógeno en cultivo. El Diazinon, un insecticida de suelo de largo efecto residual, produjo un control de la sarna ácida tan bueno como el mejor de los fungicidas que haya sido probado como tratamiento de semilla ó del suelo. Este insecticida casi no fue tóxico para el patógeno de la sarna ácida. Sugerimos que los artrópodos del suelo constituyen un factor en el desarrollo de la sarna ácida y la evidencia circunstancial que se presenta sugiere que ellos están involucrados en todo desarrollo de sarna ácida.
