To combat the problem of citrus leaf miner (CLM) which is the one of the important cause of Canker disease development, a study was conducted in research area of the Department of Plant Pathology, University of Agriculture, Faisalabad 2008-09. Fifteen commercial citrus varieties were screened to find out degree ofresistance. Kinnow exhibited the resistant response against CLM attack. Blood red and Mayer developed high CLM populations. Pine apple, mungal singh, jaffa and succari were moderately susceptible to CLM attack, whereas tangerine, malta valentia late, feutral’s early, china lemon, grapefruit musambi and sweet lemon showed susceptible response against CLM infestation. Plant extracts Withania somnifera (Aksin), Achyranthes aspera (Akk) and pesticide (Fon 75%WP used to manage the citrus leaf miner under field conditions on these fifteen citrus varieties. The most effective combination was Fon at .3g/l plus Achyranthes aspera at 7.5% against CLM infestation as 17.37 f mean value of CLM incidence as compared to control value 38.74a.
