90-day soil surfactant. 100% Active Ingredient. Three high-performance branched polymers designed for unmatched soil surfactant longevity. Combines two complementary block surfactants with a graft polymer surfactant. Increases hydration while compensating for microbial degradation of the polymer. Increased vertical and lateral movement. Perfect for fairways and areas with limited access where turf managers would prefer to make only one or two applications a year. Delivers uniform hydration, penetration, and rewetting with extremely low risk of phyto-toxicity. With Hydra-Last, two complementary surfactants are grafted onto a parent molecule in a structure resembling tree branches.
