The Trial

A small-scale trial was carried out on a tobacco farm in Centenary during the 2021/22 season. Three adjacent rows were treated differently — an untreated control, a single Azoxy Duo application, and a programme of three Azoxy Duo applications. The cured leaf from each line was photographed side-by-side so the difference in disease pressure could be compared directly.

Side-by-Side Results

Three lines of cured tobacco from the same field, treated differently.

Cured tobacco leaf — No fungicide applied

Untreated Control

No fungicide applied

Very spotty — heavy disease pressure visible on the cured leaf.

Cured tobacco leaf — ×1 spray of Azoxy Duo 325SC

One Application

×1 spray of Azoxy Duo 325SC

Few spots — a noticeable reduction in disease symptoms compared with the untreated row.

Cured tobacco leaf — ×3 sprays of Azoxy Duo 325SC

Three Applications

Recommended

×3 sprays of Azoxy Duo 325SC

No spots — and a thicker, more substantial leaf at curing.

Key Finding

A three-application Azoxy Duo programme delivered visibly clean leaf with no disease symptoms and a noticeably thicker leaf at curing.
