Effect of chitin compost and broth on biological control of meloidogyne incognita on tomato (lycopersicon esculentum mill.). Nematology. 7(1):125-132. Interpretive Summary: The root-knot nematode causes serious damage to important crops world-wide resulting in significant loss of revenue. Resistant cultivars, crop rotation, soil fumigation, and chemical nematicides have traditionally been used for management of the root-knot nematodes. Longevity and slow degradation rate of chemical nematicides creates potential environmental and human health concerns. These concerns have forced researchers to find innocuous yet efficacious methods of nematode control. Several soil microbes, which produce an array of biologically active compounds, can serve as potential biological control agents. In this study, we have demonstrated chitinase producing soil microbes can significantly protect tomato plants from root-knot nematode invasion. Information obtained from this study demonstrates that chitinase-producing soil bacteria could be utilized as potential biocontrol agents of nematodes. This practice should reduce the use of undesirable synthetic chemicals and promote maximum yield of important vegetable crops.
