Changes in Activity of Phenylalanine Ammonia Lyase (PAL), Phenols and β 1, 3 Glucanase in Crossandra Plants affected by Fusarium incarnatum (Desm.) Sacc and treated with Bioagents, Organic Amendments, Silver Nanoparticles and Fungicide in Pot Culture

Abstract

Laboratory and pot culture experiments were carried to study the effect of different bioagents, organic amendments, silver nanoparticles and fungicide in management of crossandra wilt caused by Fusarium incarnatum and nematode Pratylenchus. delattrei During the study observations are made on changes in activity of phenylalanine ammonia lyase (PAL), phenols and β 1, 3 Glucanase in crossandra plants. All the treatments applied recorded increased levels of phenylalanine ammonia lyase (PAL), phenols and β 1, 3 Glucanase in treated plants, but among all soil application (SA) of T.viride @ 2.5 kg/ha at 20 DAP plus soil drenching (SD) of carbendazim @ 0.1% at 30 DAP plus SA of T.viride @ 2.5 kg/ha at 50 DAP plus Foliar application (FA ) of P. fluorescens@ 1.0 kg/ha at 70 DAP plus Foliar application (FA ) of B. subtilis @ 1.0 kg /ha at 90 DAP was found to be significantly higher in induction of phenylalanine ammonia lyase (PAL), phenols and β 1, 3 Glucanase in crossandra. The same results are also noticed in later stage in reducing disease incidence compare to control and other treatments.
