Now is the time to protect your fruit trees and shrubs from damaging pests and disease. Dormant oils are highly refined petroleum oil which spreads uniformly on the bark of trees and shrubs to coat non-mobile, dormant insects and their eggs that are present on the plant material and suffocates them. Dormant oil can be applied anytime starting in November up until when buds begin to swell (early March).
Dormant oils can be applied in a heavier thickness than summer oils making it a very effective option. You can also add a winter disease control to the mix which helps control overwintering diseases in buds and on foliage making this a critical treatment in any spray program. Most dormant oils are OMRI approved making it one of the few organic treatments that are effective in controlling spider mites and scale.
