Abstract

Panonychus ulmi (Koch) and Bryobia rubrioculus (Scheuten) are very serious pests on apple trees in Lebanon. The effectiveness of M2060 (2 fluoroethyl (4-biphenylyl) acetate), Ovamort, Diotol, Genite, and Citronol plus parathion was investigated on the winter eggs of these two mites in the laboratory and in the field. M2060-oil was highly effective and superior to all products at early and late dormant stages of tree growth. The nearer to egg hatch the other products were applied, the more effective they were.
