Control of Honeylocust Pod Gall Midge with Foliar-Applied Insecticides, 1996

The experiment was conducted m a commercial nursery located in Milliken, Colorado. Trees used in the experiment were approximately 20 ft tall (2 inch dbh). At the time of applicaion, the trees had damage caused by lst-3rd generation pod gall midge and oviposition by 3rd generation adults was in progress. Treatments were applied on 13 Jun with a hand-held compressed air sprayer to the point of run-off. The experiment was arranged as a CRD with 7 replicates in untreated check and i replicates in all other treatments. Evaluation was done on 25 Jun by visual assessment of completely as well as partially galled new (< 2 week old) growths on the trees. Four different points per tree were sampled and the results averaged to obtain percent galled leaflets per leaf.
