Potential of chitosan alone and in combination with agricultural wastes against the root-knot nematode, Meloidogyne incognita infesting eggplant
The present investigation was carried out to evaluate the potential of chitosan alone and in combination with various agricultural wastes for the management of rootknot nematode, Meloidogyne incognita on eggplant cv. ‘BR-112’ under greenhouse conditions. The results showed that chitosan as a single...
