How to Manage Pests
Active ingredient: Carbaryl
Pesticide type: insecticide (carbamate)
See example products below.
Potential Hazard1 to
||People and Other Mammals
Foliar sprays with emulsifiable concentrate (EC) formulation:
Pests are killed by consumption, so good coverage of consumed surfaces is required. Compressed air or backpack sprayers are desirable for good coverage on trees; other sprayers are acceptable on smaller plants.
Apply dusts or sprays especially to the base of plants when eggs are laid and bugs aggregate. Repeat application about 2 weeks later. Do not apply to blossoms.
Purchase a product labeled for bark treatments and apply at the rate recommended for trunk treatments. Carbaryl applied at foliar rates will not control borers. Timing is critical. For elm leaf beetle, sprays must kill mature larvae as they crawl down the trunk. For borers, sprays must kill adults before they lay eggs and be applied to cover the trunk, crotches, and lower limbs. Keep carbaryl off foliage as much as possible to prevent killing natural enemies and inducing mite problems. Keep sprinklers directed away from the trunk to avoid washing off the spray.
