Bupirbria

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.

Características

• —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

Cómo actúa

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.
