DormBRK is a plant-based bud break formulation based on vegetable oils designed to stimulate bud break in deciduous fruit trees.
Concept
DormBRK uses refined plant oils as the active component to help release buds from winter dormancy and improve the uniformity of bud break in orchards.
Mode of action
Vegetable oils act mainly through physical and physiological effects on the bud, such as:
-
Creating a thin oil film around the bud surface
-
Modifying gas exchange and oxygen availability
-
Inducing mild metabolic stress that accelerates the end of dormancy
-
Stimulating synchronized bud activation
These processes help trigger earlier and more uniform bud break.
Advantages of plant-oil based formulations
-
Low toxicity compared with synthetic dormancy breakers
-
Suitable for integrated and more sustainable agriculture
-
Reduced risk of phytotoxicity when properly formulated
-
Can also provide suppression of some overwintering pests
Typical crops
Used mainly in deciduous orchards such as:
-
Apples
-
Pears
-
Peaches and nectarines
-
Almonds
-
Grapes
-
Cherries
Application timing
Usually applied late winter, shortly before natural bud break, when buds are still dormant but approaching the end of dormancy.
