Field Efficacy of Acaricides Against Citrus Leaf Mite Panonychus Citri Mcgregor on ACID Lime

Abstract

Field experiment was carried out to evaluate the efficacy of certain new acaricide molecules against citrus leaf mite Panonychus citri McGregor at the Agricultural College and Research Institute, Madurai during December to March 2019. Among these, fenpyroximate 5EC @1.0 ml/ l led to 85.9% reduction of mites, closely followed by spiromesifen 22.9SC @0.75 ml/ l (83.2 % reduction) and propargite 57EC @ 2.0 ml/ l (79.4% reduction). These treatments also gave higher fruit yield (14.7 t/ ha, 13.9 t/ha, 11.6 t/ha) and increased cost benefit ratio (1:2.8, 1:2.6, 1:2.2), respectively.
