Management of the Potato Cyst Nematodes, Globodera spp. through Plant Rhizosphere Bacterium Pseudomonas fluorescens Migula


Application of a formulation of Pseudomonas fluorescens Migula (Pf) in talc containing 15x108colony forming units per g @ 10 and 20 kg per ha and carbofuran @ one kg a. i./ha reduced potato cyst nematode parasitization of potato roots by 47.7, 62.6 and 81.3 per cent, respectively. Earlier root entry of nematodes was observed in control and Pftreatments. The nematodes in these treatments were in the fourth juvenile or adult stage while they were in the second or third-stage under carbofuran. Potato tuber yield was higher by 29.4,39.4 and 77.8 per cent under Pf @ 10 kg/ha, Pf @ 20 kg/ha and carbofuran @ one kg a. i./ha, respectively.
