Apply after bud break and repeat at 45- to 60-day intervals for up four applications. Do not apply within 60 days of harvest. mefenoxam Gold EC 0.25 pt/1,000 ft of row Gold GR 5.0 lb/1,000 ft of row Apply in 3-ft bands over rows.

Apply a drench of at least 100 gal/acre. Brigade labels recommend at least 200-400 gals/acre as a drench for controlling raspberry crown borer. If applying a prebloom drench, it is prohibited to also apply a prebloom foliar application of any *bifenthrin product. Crown borer treatment can also be made in the fall.
