Flutriafol acts against the following diseases in cereals:
Leaf spot
- Septoria tritici
Glume blotch
- Septoria nodorum
Brown rust
- Puccinia recondita
Yellow rust
- Puccinia striiformis
Stem rust
- Puccinia graminea
Leaf rust
- Puccinia hordei
Powdery mildew
- Erysiphe graminis*
Leaf scald
- Rhyncosporium secalis
Net blotch
- Helminthosporium
And to some extent flutriafol acts against eyespot (Pseudocercosporella herpotrichoides).
* Where triazole sensitive strains are present.
Curative Activity
Applied up to 28 days after an infection period, and before symptoms appear, Impact® demonstrates excellent curative activity against Septoria tritici-'kick-back' or 'claw-back' activity.
Flutriafol also demonstrates eradicant activity against yellow rust (P.striiformis). The addition of a morpholine to a flutriafol product will enhance the activity against established rusts.
Protectant Activity
Maximum control of diseases is normally accomplished by timely spraying, usually just before the development of infection. Impact® possesses very good protectant properties, often similar to true protectant fungicides.
Very good protectant activity against rusts (P.striiformis and P.recondita) is a feature of Impact® activity. This is clearly demonstrated in the graph below where control of yellow rust was measured up to 42 days after application at GS37. When used before disease is established, Impact® can have 6-8 weeks effect, sometimes longer.
