ABSTRACT
The field investigations were conducted during the year 2013 at Krishi Vigyan Kendra (KVK), Balpora (Shopian) a constituent of S.K. University of Agric. Sci. and Techn. of Kashmir and private apple orchard of Zawoora (Srinagar),to study the efficacy for some horticultural mineral oils at 2, 2.5 and 3 per cent concentration in comparison with Diesel oil emulsion (DOE) at 1:7, 1:10 and 1:12 ratio against San Jose scale (SJS) Quadraspidiotus perniciosus (Comstock). The DOE at all three concentrations proved effective against suppressing the mortality of San Jose scale and were superior to other treatments The efficacy of all the treatments in respect of exhibiting pest mortalities followed the order of DOE @ 1:7 ratio > DOE @ 1:10 ratio > MAK spray oil @ 3.0 % > DOE @ 1:12 ratio > Arbofine spray oil @ 3.0 % > MAK spray oil @ 2.5 % > Arbofine spray oil @ 2.5 % > MAK spray oil @ 2.0 % > HP spray oil @ 3.0 % > Arbofine spray oil @ 2.0 % >HP spray oil @ 2.5 % > HP spray oil @ 2.0 %.
Key words :
Apple, Diesel oil emulsion, Horticultural mineral oils, Mortality, San Jose scale.
