Comparative Evaluation Of Nano Fungicides And Fungicides For Management Of Late Blight Of Potato Caused By Phytophtora Infestans Mont De Bary

Abstract

Potato (Solanum tuberosum L.) is one of the most important vegetable crops across the world and in India. It is the fourth major important food crop after Wheat, Rice and Maize due to its higher yield potential and high nutritive value. Late blight disease is an important disease of potato worldwide and can cause significant reduction in the economic value of potato, resulting in 80-100 % yield loss. newlineThe management of the disease can be done through conventional methods viz., biological, chemical and cultivation of resistant variety. Therefore, inquest for management of Late blight by certain nanofungicides like Agritec nanofungicide, Silver nanofungicide, Selenium nanofungicide and Nickel nanofungicide and fungicide viz. Matco, Mataxaly, Mancozeb and propoconazol were used during the course of present investigation and their morphoological and biochemical changes in potato plant were ascertained. Nanofungicide and fungicide were assessed under in vitro condition, on inhibition of growth and development of pathogen. The maximum inhibition of mycelial growth of P. infestans was recorded with suitable concentration from Matco fungicide at 0.2% treatment representing 80.25 % reduction in growth over control newline newline
