Systec 1998

  • Foliar Spray

SysTec 1998® is a systemic fungicide used to control various foliar diseases which may cause unsightly leaf damage, unseasonal leaf drop, thinning canopies, and a generally weakened and stressed appearance. These diseases are not typically life-threatening; however, by attacking the foliage, they can make the tree susceptible to other harmful organisms.

The liquid formulation of SysTec 1998® provides excellent tank mix compatibility and ease of application.

  • Anthracnose, black spot, apple scab, scab diseases, leaf spot diseases, powdery mildew, tip blight of pine, stem and crown rot (cylindrocladium rot and thielaviopsis rot)

More information and a rate card are available in the Systec 1998 Product Guide.
