Control of White Pine Weevil in Young Jack Pine Plantations with Permethrin and Methoxychlor
Abstract:The efficacy of mistblower applications of permethrin at 70 g and 140 g active ingredient (ai)/ha and methoxychlor at 1.1 kg ai/ha was evaluated for the control of white pine weevil in young jack pine plantations. The results from 2 yr of testing indicate that 1-3% of the leaders were weevil-damaged after insecticide treatment compared to 9-13% in untreated plantations. Generally, all three insecticide treatments were similarly effective in reducing weevil damage. Additional field trials with permethrin at 70 g ai/ha showed that effective applications can be made as late as 2 wk after the first weevils have emerged in the spring from the soil. Mistblower applications of permethrin and methoxychlor can be an effective method to control the weevil in high value jack pine plantations such as seed orchards and genetic test sites where silvicultural and cultural control techniques are impractical.
