Eco-friendly management of powdery mildew and rust of garden pea (Pisum sativum L.)

Abstract

An experiment was conducted at the Sam Higginbottom University of Agriculture, Technology and Sciences, Allahabad, Uttar Pradesh in Rabi season of- 2016-17. A field experiment was conducted in RBD with four botanicals i.e neem products (Neeem leaves extract 10%, NSKE 5%, Neem oil 3%, Nimbicidin 0.3%,), a bio-agent (P.fluorescens 0.5%), along with chemical spray (Carbendazim- 0.1%) as foliar sprays and control (no spray) against powdery mildew and rust of pea. During evaluation, all the six treatments were found to be significantly superior over control in managing the powdery mildew and rust disease. Among all the treatments T6- carbendazim (0.1%), followed by T2-NSKE (5%), T4 - nimbicidin (0.3%), were significantly superior over other treatments for managing powdery mildew,whereas T6- carbendazim (0.1%), followed by T4 - nimbicidin (0.3%), T3- neem oil (3%), were significantly superior over other treatments in managing rust disease. During evaluation, Neem Seed Kernel Extract at 5% concentration and nimbicidin(0.3%) were found as best treatment to control for powdery mildew and rust disease respectively.
