One of the major problems in plantation and horticultural crops including vegetables are nematodes. Scientific study reports about 20,000 identified soil nematode. Nematodes feed damage the plant roots and reduce the water and nutrient uptake which result in reduction in yield.
In addition, the infested plant becomes more vulnerable to other stress factors such as heat, water, nutritional deficiencies and disease-causing organisms. It is difficult to control the nematodes with common chemical pesticides.
