COMPATABILITY OF PSEUDOMONAS FLUORESCENS, VAM (GLOMUS FASCICULATUM), TRICHODERMA HARZIANUM AND PESTICIDES ON ESTABLISHMENT AND GROWTH OF BLACK PEPPER UNDER NURSERY CONDITION

Abstract

Black pepper, commercially important spice propagated mainly by rooted cuttings raised in the nurseries. In order to produce vigorous plants for better establishment, an experiment was undertaken with various combination of Pseudomonas fluorescens, (IISR6), V AM (Glomas fasciculatum) and Trichoderma harzianum, fungicides and nematicides. It was observed that combined use of VAM+ IISR6 along with phorate and COC spray resulted in better establishment and growth of black pepper plants. The production of significantly higher number of leaves, leaf area, maximum root length and total biomass were noted in this treatment followed by the application of IISR6 alone. Application of IISR6 alone or combination with other biocontrol agents are suggested for ecofriendly management of diseases and production of vigorous black pepper rooted cuttings in the nursery
