Host Parasite relationship, Host range and Management of Reniform nematode in Soybean

Females entered through root epidermis, penetrated the endodermis and fed on pericycle. Eight crops namely, Triticum aestivum, zea mays, Oryza sativa, Hordeum vullgare. Sorghum bicolor, Allium cepa, Brassica species and Arachis hypsogea were found to be non host plants. Carbofuran @ 3g/500cm³ soil was superior over botanical plants, in terms of reduction in nematode population both in soil and roots. Application of Azadirachta indica leaves in soil reduced the nematode population by 62% followed by Tagetes erecta 56% and 51% in Carica papaya. It is concluded that growing non host crop and use of botanicals were better option to bring down nematode polulation in soil to a safer level.
