Opal offers excellent disease control on a wide range of crops. Opal can be used on a range of vegetables, fruit, ornamental plants & trees to control a range of diseases including alternaria, rust, downy mildew & ring spot.

Opal contains azoxystrobin, a broad spectrum fungicide from the strobilurin group. It has systemic, translaminar and protectant properties which inhibits fungal respiration. Its mode of action is different from the action of other fungicidal groups, however it should always be used in mixture with fungicides with other modes of action. Opal shows good crop safety, disease control and maintenance of green leaf area which results in significant yield benefits. Use Opal as a protective treatment or during early stages of disease establishment. A full list of the tolerant crops can be found on the product label and below.

Certain apple varieties are highly sensitive to Opal and as a precaution it should not be applied when there is a risk of spray drift onto neighbouring apple crops. Spray equipment used to apply Opal to other crops should not be used to treat apples.

Apply Opal under good growing conditions with adequate soil moisture. Avoid poor growing conditions which may give less reliable results.

To help increase the effectiveness by over 20%, mix in with Ruby.
