Spur Shield®
Prevent disease in pruned crops with Spur Shield®. Powered by Pinolene®, it seals wounds to block moisture and help healing in cold, wet conditions.
Overview
Spur Shield® protective sprayable barrier is a Pinolene® terpene polymer-based resin wound sealant designed to help protect pruning cuts and bark injuries during vulnerable stages of the growing cycle. When applied to fresh cuts, Spur Shield® forms a breathable, elastic film that seals out moisture and creates a physical barrier against pathogens like Eutypa dieback, Botryosphaeria canker, and Esca.
Its terpene polymer base—derived from Pinolene®—provides natural adhesion to bark surfaces and remains flexible under environmental stress. This helps shield wounds during cold, wet pruning seasons when bacterial and fungal threats are at their peak.
Application
Key crops include, but are not limited to, grapes (wine, table, raisin), cherries, plums, almonds, hazelnuts, blueberries, and other tree and vine crops
Apply via foliar spray, backpack sprayer, or daub wand
Apply immediately after pruning and before rainfall, irrigation, or fog events
May be tank mixed with compatible fungicides; consult label for compatibility
Actual results may vary depending on equipment, crop, and environmental conditions. Always refer to the product label for specific application rates and safety recommendations
How Does Spur Shield® Protective Sprayable Barrier Work?
By leveraging the natural strength of Pinolene® terpene polymer, Spur Shield® creates a breathable, water-resistant film over pruning wounds. This elastic seal forms a protective barrier that keeps out rain, fog, and dew while allowing internal moisture to escape—reducing the potential for pathogen intrusion and infection.
When applied to fresh pruning cuts, Spur Shield® adheres to bark and wood tissue, helping limit entry points for pathogens such as Eutypa, Botryosphaeria, Phomopsis, and other wood-infecting fungi. Unlike hand-painted sealants, Spur Shield® sprays on quickly and evenly for complete coverage with less effort.
