Turf Marker products dissipate quickly in wet and dry weather and mixes completely with water soluble pesticides and fertilizers without affecting chemical efficacy. Versatile and easy-to use, they are non-toxic spray pattern indicators for turf and ornamental, aquatic, industrial, municipal, utility, and rights-of-way use only. Turf Marker products show applicators where they have sprayed and will help avoid costly oversprays and skips.
