Parsnips, swedes and turnips

Using Rudis fungicide as a Qualified Minor Use recommendation.


Rudis Qualified Minor Use

Rudis use on parsnips, swedes and turnips are Qualified Minor Use recommendations. There is limited evidence of crop safety and/or product efficacy and the commercial risk of using Rudis under these Qualified Minor Uses is borne entirely by the grower.


Rate of use: 0.4 L/ha
Max number of doses per crop: 3

Based on limited data Rudis will control leaf blight (Alternaria dauci), Sclerotinia rot* (Sclerotinia sclerotiorum), powdery mildew (Erysiphe heraclei) in parsnip and powdery mildew (Erysiphe cruciferarum) and Alternaria (Alternaria brassicae) in swedes and turnips.

*Moderate control.

Apply the first application before disease establishes itself in the crop. This should be followed by further doses at an interval of about 21 days.
