Supressiveness of rot knot nematode in sugarcane by addition of stillage in the soil

Abstract

Stillage has shown high potential for use in agriculture, being widely applied in soil, especially in fertirrigation. The physical, chemical and biological modification on soil properties provides increase in availability of nutrients to the plants and probably suppressiveness induction of soil-born plant pathogens. In the present study, the effects of stillage application in soil on rot knot nematodes (Meloidogyne javanica and M. incognita) hatching and reproduction were evaluated under greenhouse and laboratory conditions. The results pointed out that the nematode eggs exposure to stillage affected hatching of both nematode species negatively. The addition of increasing residue rates decreased nematode eggs and juveniles densities in sugarcane. The inhibitory effect was directly proportional to stillage rate.

Key words:
Saccharum; Meloidogyne; residue use
