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
