We are starting to see Shortstop 2SC being used for many of the secondary effects. When Shortstop 2SC is applied, not only will above ground growth be regulated, but we also see thicker leaves, waxier leaves, increased fibrous roots, and healthier looking plants. With these secondary effects, we are observing trees with less leaf scorch due to drought, less damage after construction, and an increase in disease suppression.
Shortstop 2SC has 9 categories for treating trees. It is important to follow the label and treatment guidelines, as each species of plant will have varying levels of sensitivity to the active ingredient.
Symptoms of Over-Regulation
The plant may have atypically small and distorted leaves. Small flowers and delayed blooming and leaf-out may occur.
Management: Over-Regulated Trees and Shrubs
Immediately remove the soil that was treated with Shortstop 2SC. This will reduce additional uptake of the active ingredient into the tree or shrub.
Replace with organic matter and new soil – this will help absorb any additional product.
For trees, consider a trunk injection with PHOSPHO-jet™. This will trigger the plant’s natural defense and encourage strong cell walls.
