Abstract

Field experiment was conducted during kharif season for consecutive two years, i.e. 2014 and 2015 to evaluate bio-efficacy of certain acaricides viz. pyridaben 20% WP (different concentration), propargite 57% EC and fepyroximate 5% EC against broad mite on chilli crop (variety G-4) under field condition. The maximum suppression of mite population (80.42%) was recorded in propargite treated plots followed by pyridaben @ 125 g.a.i./ha (78.33%) and pyridaben @ 100 g.a.i./ha (75.29 %). Other treatments didn’t show comparative effective result. The chilli yield obtained was also superior in case of propargite (2380.21 kg/ha) and pyridaben @ 125 g.a.i./ha (2265.33 kg/ha) in comparison to control plot (1263.25 kg/ha). In overall view the performance of both propargite and pyridaben @ 125 g.a.i./ha remained at par among other treatments both in terms of controlling chilli mite and increasing yield attributes of chilli fruits.
