BHA’s Di-Bak T
What is it?
Tebuthiuron is a urea group inhibitor of photosynthesis photosystem II (Herbicide Group C). It binds to D1 proteins and blocks electron transport that stops CO2 fixation but more importantly formation causes the creation of highly reactive molecules that start a chain reaction destroying lipids and membranes. Tebuthiuron is generally active against many woody plants.
What is its fate in plants?
It is systemic and nonselective. It is readily absorbed by roots and transported to leaves and foliage. This herbicide is only translocated apoplastically (upwards) through the xylem.
What does BHA technology avoid?
It is highly water soluble and does not exhibit strong adsorption to soil particles and has a long half-life (Av. 360 days). This high mobility in soil and long half-life has led to use of tebuthiuron being banned in Europe.
The benefit of delivering BHA’s Di-Bak T is that it penetrates the weed trunk or stem directly where the capsules then dissolve – with no run-off or groundwater contamination.
