Downy mildew is the first to attract all your attention in the onions every year. Effective protection can be obtained by applying Acrobat DF preventively in a timely manner through a schedule.
Acrobat DF works (because of the 2 active substances) in different ways. Dimethomorph is incorporated into the leaf and has a preventive and curative effect and mancozeb, as a broad-acting contact fungicide, mainly has a preventive effect. To make the most of 'Acrobat DF', it is recommended to add an effective and versatile adjuvant (such as Promoter).
Design
Our advice is to use 2,5 kilos per hectare Acrobat DF and 0,3 liters per hectare Promoter. Later in the season, Scala can also be added against leaf spots. This may already be necessary for first-year onion sets. Scala is a new active ingredient for onions, which is very effective against botrytis and stemphylium. Scala is gentle on the crop and can also be added to other products. This fungicide also fits perfectly in an anti-resistance strategy.
