Di-Bak TyP (Triclopyr)
Benefits of BHA technology
- Targeted injection of the herbicide directly into the tree
- Can be used in all weather conditions and all year round
- Easy application with hand-held applicator
- Safe to use as there is no direct contact with herbicide as it is in capsule form
- It is a systemic and persistent herbicide.
- This herbicide is capable of moving with sugars to sites of metabolic activity such as root tips and underground storage organs.
- It can remain active in the plant until the plant dies and microbial activity destroys the herbicide.
- It has little or no action against grass species.
- If it comes in contact with soil, triclopyr will bind (adsorb) to soil particles and following rain it has little mobility and tends to stay within 30 cm of the soil surface. It therefore poses no significant environmental hazard due to leaching.
- In the soil, it undergoes degradation by soil micro-organisms (fungi and bacteria) and sunlight (photolysis). Final breakdown products are carbon dioxide, water and organic acids. The average half-life of triclopyr in soil is 46 days (range 36-90 days).
How does Triclopyr work?
- Triclopyr is a selective pyridine herbicide (Herbicide Group I) that mimics the plant growth hormones (auxins) of broad-leaf and woody plants.
- It stimulates rapid unregulated cell division and growth leading to cell rupture and death.
- After application into the stem, triclopyr is distributed by the plant’s water (xylem) and nutrient transportation (phloem) systems into the leaves and roots
