Why Worry About Crown Gall?

Crown gall is a serious plant disease that reduces yields and shortens the lives of trees, vines, and shrubs.  It also provides a “door” for wood decay fungi to invade roots and trunks, resulting in plant structural failure.


A bacterial biological control with nearly 40 years of unmatched disease prevention.  Fresh cultures of GALLTROL-A are ready for same-day shipping and have shelf-lives of 120 days under refrigeration.  GALLTROL-A  is mixed with water and applied as a spray or dip within 12 hours of plant wounding.  GALLTROL-A colonizes wounds and prevents infection by the crown gall pathogen.  Certain pathogen strains are less susceptible to control with GALLTROL-A compared to others.  GALLTROL-A is registered with the Washington State Department of Agriculture for use on organic crops.



A ready-to-use, flowable, chemical emulsion applied as a paint that eradicates existing galls.  GALLEX works by selectively penetrating and killing gall cells but does not harm healthy plant tissues.  It is packaged in cases of 4 x 1.0 gallon plastic jugs.

“Galltrol-A has been our chosen product since 1985.”
