Management of bacterial blight of anthurium (Anthurium andreanum Linden.) using ecofriendly materials

Abstract

Four ecofriendly materials viz., turmeric powder impregnated in sodium bicarbonate (0.15%), neem oil (2%), Pseudomonas fluorescens (a proprietary product at 1.5%) and cow dung extract (7.5%) were compared with streptocycline (100µg ml-1) and Captan (0.3%) for their efficacy in controlling bacterial blight of anthurium. Five sprays (at weekly intervals) of both turmeric powder and streptocycline proved to be very effective and gave 100% control as against 97% for Pseudomonas, neem oil, and Captan; cow dung extract, however, was less effective (75%).
