Now’s the time to control over-wintering insects and diseases:

• Spray trees and shrubs with Bonide Tree & Shrub Insect Control Guard & Grow to reduce insect population.
• Spray for spider mites with Ultra-Fine Oil on needles and limbs of arborvitae, cryptomeria, false cypress, fir hemlock, juniper, pine, yew and spruce (except blue spruce).
• As the leaves begin to open on azaleas and rhododendron, spray with Fung-onil to prevent flower blight and leaf blight on azaleas. Remove and destroy gals and repeat spraying weekly through blooming. Fung-onil should also be sprayed on crabapples for scab and cedar apple rust and Dogwood (as buds swell) to control anthracnose.
• Apply Bonide Fruit Tree Spray as buds swell and again at petal drop to all fruit trees.
• To control leaf spot on Mt. Laurel, spray with Fung-onil when new leaves are about an inch long. Also spray roses at bud break to control botrytis and black spot if you haven’t already done so.
• Remove infected stems and litter of pachysandra and begin spraying every 2 weeks (until hot weather) with Liquid Copper or Fung-onil to control volutella blight.
