Exoskeleton of shrimp to control the nematode nodulator, Meloidogyne incognita, in tomato in the greenhouse

Abstract

A soil amendment of shrimp shell at dosages of 2 and 4% (v/v) applied 25, 30 and 35 days before planting reduced damage to tomatoes caused by Meloidogyne incognita, decreasing root galling and increasing height and dry weight of plants. The 4% dosage applied 30 or 35 days before planting increased shoot dry weight of tomato plants grown on nematode infested soil in the greenhouse.
