Bupirbria
A powdery mildew specialist with vapour action and a clean record on beneficials.
Bupirbria is a systemic fungicide based on bupirimate, developed specifically against powdery mildew. Two things make it useful in a programme: it acts partly in vapour phase, so it reaches mildew on leaf undersides and in the shaded interior of a canopy that no spray reaches, and it is notably gentle on predatory mites and other beneficials — which matters in apple and protected crops where an acarine balance is being maintained.
Characteristics
- Specialist powdery mildew activity in apple, vine, rose and cucurbits
- Vapour-phase action reaches shaded and unwetted canopy
- Systemic with curative as well as protective effect
- Gentle on predatory mites and beneficial insects — suits IPM
- FRAC Group 8 — a distinct target from the triazoles and strobilurins in the range
- Long-standing, well-understood chemistry
How it works
Bupirimate inhibits adenosine deaminase in the fungus, disrupting nucleic-acid metabolism — a target unrelated to the sterol synthesis the triazoles block or the respiration the strobilurins block, which is why it rotates cleanly against both. FRAC Group 8.
