Chemical Control of Meloidogyne Incognita in Tomato Nursery

Four chemicals viz., aldicarb, carbofuran, phorate and quinalphos were evaluated against root-knot nematodes (Meloidogyne incognita) infecting tomato under nursery and field conditions. Aldicarb and carbofuran were effective in increasing the number of seedlings per bed, whight of seedlings and in reducing the gall index in nursery. Seedlings raised from aldicarb and carbofuran treated beds also gave better fruit yield and showed least root-knot index under field conditions.
