TK-13 Annual and Perennial Weed Control

TK-13 is an EPA registered, ready-to-use, non-selective herbicide that kills all types of broadleaf and grass weeds. It will kill the entire plant – roots, stems and leaves, but only when it is absorbed by the foliage. TK-13 deactivates on contact with the soil and will not leach through the soil to damage desirable plants. The active ingredient in this product is active against a substance found only in plants. It enters the plant through foliage and is translocated throughout the plant, killing both roots and top growth. Sprays not absorbed by plants are broken down into natural materials.
