AB  - Trunk-injected abamectin applied at the rate of 0.5 ml of 2% a.i. formulation for every 10 cm of trunk circumference effectively controlled the elm leaf beetle on Siberian elm. Treatments applied in May before hatching of first-generation larvae reduced defoliation levels in June and August. Foliage from treated trees remained toxic to elm leaf beetle larvae 83 days after treatment. Some phytotoxicity was observed around the treatment holes.
