Control of aphid-borne potato virus Y in potatoes with oil emulsions (original) (raw)

Abstract

Tests were made at Presque Isle, Maine, from 1963 through 1965 to measure the effect of oil sprays on the spread of potato virus Y (PVY) in Green Mountain potatoes. In 1963, 4 weekly applications of a 1% mineral oil emulsion at 1.25 gal oil/acre(4.71/.41 ha) did notaffect significantly (P = 0.05) the spread of PVY. In 1964, the 64% control of PVY spread from 5 weekly applications of mineral oil emulsion at 1.25 gal/acre was not significantly different at that level from the 55% control from 5 weekly applications of the oil emulsion at 2.5 gal/acre (9.5 1/.41 ha). Three or 5 weekly applications of an alkylated naphthalene (Velsicol AR-60®) spray at 1.25 gal/acre significantly increased spread of PVY compared to that from 5 applications of the oil at 1.25 or at 2.5 gal/acre. In 1965, from 69 to 75% control of PVY spread resulted from 6 weekly applications of a paraffin oil emulsion at 2.5 gal/acre. The percent spread from the 6 weekly applications was smaller, but not significantly so (P = 0.05), than from 3 weekly applications made during the first half of the same 6-week period. In these tests, relatively light spread of PVY occurred, and control of spread was rather variable but the results indicate that oil emulsion sprays offer promise for protecting potato plants from PVY infection.

Resumen

Pruebas para medir el afecto de aplicaciones de aceite sobre la diseminación del Virus Y de la papa (PVY) en papas Green Mountain se realizaron en Presque Isle, Maine desde 1963 hasta 1965. En 1963, 4 aplicaciones una vez porsemana de una emulsión de 1% de aceite mineral a 1.25 gal. aceite/acre (4.71/0.41 ha) no afectó significativamente (P = 0.05) la diseminación de PVY. En 1964 el 64% de control de la diseminación de PVY con 5 aplicaciones una vez por semana de una emulsión de aceite a 1.25 gal/acre no fué significativamente diferente a ese nivel que el 55% de control con 5 aplicaciones una vez por semana de 2.5 gal/acre de emulsión (9.51/0.41 ha). Tres o cinco aplicaciones una vez por semana de naftaleno alkylado (Velsicol AR-60®) a 1.25 gal/acre aumentó significativamente la diseminación de PVY comparado con cinco aplicaciones de aceite a 1.25 ó a 2.5 gal/acre. En 1965 se obtuvo de 69a 75% de control de diseminación de PVY con 6 aplicaciones una vez por semana de una emulsión de aceite de parafina a 2.5 gal/acre. El porcentaje de diseminación con las 6aplicaciones una vez por semana fué m=’as pequeflo pero no estadisticamente significativo (P = 0.05) que con 3 aplicaciones una vez por semana hechas durante la primera mitad de ese mismo período de 6 semanas. En estas pruebas hubo relativamente baja diseminación fue bastante variable pero los resultados indican que la aplicación de emulsiones de aceites son promisoras para proteger las plantas de papa de la infección con PVY.
