Abstract

Experiments were conducted in the glasshouse and in the field with the egg parasitoid Paecilomyces lilacinus, neem as leaves and cake, farm yard manure, fenamiphos 10G and carbofuran 3G at different dosages, in a single and split application, for the management of Meloidogyne incognita on papaya. Carbofuran at the rate of 3 g c.f./kg of nursery soil mixture and 2 g c.f. per plant application, for the management of Meloidogyne incognita on papaya. Carbofuran at the rate of 3 g c.f./kg of nursery soil mixture and 2 g c.f. per plant applied in two equal split applications, before planting and at flowering, controlled M. incognita population in the glasshouse and the field, respectively, and increased the plant growth and fruit yield of papaya. The increase in number of fruits, mean fruit weight and fruit yield per plant was 40, 14 and 62%, respectively, compared to untreated. Neem cake at 5 g per kg of nursery soil mixture and 1 kg per plant in the field was effective but less than carbofuran. Fenamiphos was as effective as neem cake in the glasshouse.
