Abstract
Field efficacy of horticulture mineral oil Rilso 999 and MAK All Season at different concentrations were evaluated at two locations i.e., Lar (District Ganderbal) and Hajin (District Bandipora) of J&K during 2017 and 2018, all the treatments were significantly superior in terms of mortality of San Jose scale Quadraspidiotus perniciosus (Comstock) (SJS) and European red mite (ERM) Panonychus ulmi (Koch) as compared to untreated control. The cumulative mean mortality of SJS (58.08% and 62.20%) and ERM (58.69% and 53.65%) at recommended dose of 7.5 ml/ l of water both for standard check (MAK All Season) and Rilso999, respectively. Maximum (27.14 and 19.63 %) cumulative mortality of Amblyseius spp. and Coccinellids were recorded with Rilso999@ 10 ml/ l of water, respectively. No phytotoxicity symptoms viz., leaf injury, yellowing, wilting, necrosis, hyponasty and epinasty were observed with Rilso999 at 15 ml/ l of water. Maximum yield (246.16 kg/tree) was attained with MAK (standard check) @7.5 ml/ l of water.
