SUPPRESSION OF NEMATODE POPULATIONS WITH ANIMAL BY-PRODUCTS

The incorporation of blood, fish and meat wastes into the soil was eff ective in reducing the populations of plant-parasitic nematodes and im proved pigeon pea (Cajunus cajan L.) plant growth. Lower dosages (1 an d 5% (w/w)) gave the best responses and the highest dose (10% (w/w)) s howed phytotoxic effects. There was a correlation between reduced nema tode populations and increased plant growth. Blood waste amendment to soil was the most effective nematode suppressant, followed by meat and fish wastes.
