clopyralid (Transline)
Rate Spot treatment: 0.5% solution.
Time Apply to actively growing vegetation.
Remarks Mix with 0.25% by volume nonionic surfactant and apply to all exposed foliage. Repeat applications may be required to achieve full control.
Caution Do not contaminate water. Potatoes, beans, and many other crops are very sensitive to clopyralid. Do not use in diversified cropping areas.
Site of action Group 4 synthetic auxin
Chemical family Pyridine
glyphosate
Rate Spot treatment: 1 to 2% solution of 3 lb ae/gal product.
Time Apply to green foliage in late summer to early fall.
Remarks Adequate foliar coverage of cape-ivy is necessary, and repeat applications may be required to achieve full control. Add nonionic surfactant if not included in the formulation. Late summer treatments after native plants are dormant are preferred to minimize injury.
