Abstract

The results showed that the application of Pseudomonas fluorescens (Pf1) at 2.5 kg/ha significantly reduced population of Pratylenchus zeae (173.2/200g of soil as compared to the untreated control (648.5) at 360 days after planting which resulted in 73.2% reduction over control. The same treatment were also enhanced the number of millable cane (161.49 000’/ha), commercial cane sugar % (12.7), cane yield (129.4 t/ha) and sugar yield (16.38 t/ha). Regarding the application of fungal antagonists Paecilomyces lilacinus @ 2.5 kg/ha also found significant reduction in the nematode population at 197.8 in 200 g of soil after 360 days of planting as compated to control. Application of P. lilacinus had enhanced number of millable cane (164.94 000’/ha), commercial cane sugar % (12.8), cane yield (129.8 t/ha) and sugar yield (16.61 t/ha).
