REDUCING THE USE OF FUNGICIDES SPRAYS WITH NATURAL COMPOUNDS AND BIOCONTROL AGENTS FOR LATE BLIGHT MANAGEMENT: A REVIEW
Abdul Majeed
Abstract
Late blight of potato, a pathogenic disease of members of Solanaceae caused by Phytophthora infestans, has drastic effects on yield and quality of potato and tomato. The disease is generally managed by exhaustive applications of different fungicides, which manifests an efficient mechanism to minimize yield losses; however, the evolution of new pathogenic strains of P. infestans with unusual virulence potentials and fungicide resistance and environmental problems caused by fungicide use has drawn much attention in recent times to revise the disease control methods. Addressing the public and scholarly concerns over the frequent uses of late blight fungicides, novel, eco-friendly and safe, natural compounds are needed to be used as fungicides alternative for controlling late blight disease. This article reviews the potential role and efficacy of some natural compounds as alternative agents to commonly used fungicides. The discussion particularly focuses on plant and compost extracts, essential oils and biological antagonists as a whole or their products as possible substitutes or analogues to synthetic fungicides.
