Management of the Potato Cyst Nematodes, Globodera spp. through Plant Rhizosphere Bacterium Pseudomonas fluorescens Migula
Application of a formulation of Pseudomonas fluorescensÂ Migula (Pf) in talc containing 15x108colony forming units per g @ 10Â and 20 kg per ha and carbofuran @ one kg a. i./ha reduced potato cystÂ nematode parasitization of potato roots by 47.7, 62.6 and 81.3 per cent,Â respectively. Earlier root entry of nematodes was observed in controlÂ and Pftreatments. The nematodes in these treatments were in the fourthÂ juvenile or adult stage while they were in the second or third-stageÂ under carbofuran. Potato tuber yield was higher by 29.4,39.4 and 77.8Â per cent under Pf @ 10 kg/ha, Pf @ 20 kg/ha and carbofuran @ oneÂ kg a. i./ha, respectively.
