PGR treatment happens in early spring for Ginko, Locust and Walnut trees.

End messy fruit and seed production with Pinscher PGR (plant growth regulator). Use it on ornamental trees with undesirable fruit or seed production that requires ongoing cleanup or causes turf maintenance problems. Pinscher PGR reduces flowering and fruit/seed set without compromising tree health. Annual application of Pinscher PGR will substantially reduce cleanup, maintenance, labor and other costs. Application timing varies for tree species but Ginko, Locust and Walnut trees should be treated in early spring. Crabapple, Catalpa, Coffee tree, Cottonwood, Mulberry and Sweetgum trees should be injected with Pinscher in late summer. Enjoy the tree. Not the mess of the tree.
