Mishra, D.N., Kumar, K., & Singh, L.R. 2004 Efficacy and economics of some insecticides against scale insect Melanaspis glomerata G. infesting sugarcane ratoon crop under mid western plain zone of UP.. Environment & Ecology 22(Spl-4): 752-754.

Notes: The efficacy of different insecticides, viz. imidacloprid (25 ml a.i./ha), dimethoate (800 ml a.i./ha), cypermethrin (400 ml a.i./ha), monocrotophos (750 ml a.i./ha), methylparathion [parathion-methyl] (700 ml a.i./ha) and neem oil (2 litres/ha) sprayed on sugarcane was evaluated against the scale insect pest, M. glomerata in Nagina, Uttar Pradesh, India in 2000-2002. Imidacloprid was the most effective, followed by cypermethrin during both years. However, additional gain per rupee invested was higher with monocrotophos than imidacloprid.
