Abstract

Biological and chemical control of Pythium aphanidermatum (Edson) Fitz.-Meloidogyne incognita (Chitwood, 1949) disease complex in chilli (Capsicum annum L.) and brinjal (Solanum melongena L.) were evaluated in field. Seed treatement with Diafuran 3G+ Ridomil MZ-72, significantly reduced the incidence of damping-off followed by seed treatment with Ridomil MZ-72, Trichoderma viride, T. harzianum and Paecilomyces lilacinus treatments. There was increase in dry shoot and root weight of both crops, when T. viride was used as seed treatment followed by P. lilacinus and T. harzianum. The nematode gall-index was highly reduced in Diafuran 3G+ treatment followed by P. lilacinus and Diafuran 3G-Ridomil MZ-72 treaments.
