Abstract

Aldicarb was applied directly to potato seedpieces at 0.3, 0.6, 1.1, 2.2 and 3.4 kg AI/ha at planting and at 2.24 kg Al/ha over the plants at crop emergence. All seedpiece treatments resulted in superior early season protection from Colorado potato beetle,Leptinotarsa decemlineata (Say). Lower seedpiece rates lost effectiveness by early July, while higher rates protected foliage into early August. In a second study, plots treated with 1.1 kg AI/ha to the seedpiece produced crop yields as high as those treated with additional aldicarb at crop emergence. It is suggested that low rates of aldicarb applied directly to the seedpiece at planting could offer effective early season insect control while reducing the risk of groundwater contamination.

Compendio

Se aplicó Aldicarb directamente a los tubérculos-semillas de papa en la proporción de 0,3, 0,6, 1,1, 2,2 y 3,4 kg IA/ha al momento de la siembra y 2,24 kg IA/ha al momento de la emergencia de las plantas. Todos los tratamientos a la semilla dieron una protección superior al inicio del período vegetativo contra el escarabajo de Colorado (Leptinotarsa decemlineata Say). Las dosis bajas a los tubérculos-semillas perdieron su efectividad a comienzos de julio, mientras que las dosis más altas protegieron el follaje hasta agosto. En un segundo estudio, las parcelas tratadas con 1,1 kg IA/ha a los tubérculos dieron un rendimiento tan alto como aquellas tratadas adicionalmente con Aldicarb al momento de la emergencia. Se sugiere la posibilidad de que dosis bajas de Aldicarb aplicadas directamente a los tubérculos-semillas al momento de la siembra ofrecerían un control efectivo del insecto al inicio del período vegetativo, al mismo tiempo que reducirían el riesgo de contaminación por el agua.
