We are now at the peak of the powdery mildew season and, with increasing temperatures and dry weather conditions, susceptible crops are likely to be at high risk of infection.
There are five different powdery mildew species which attack ornamental crops in the UK.
Takumi SC (cyflufenamid) is particularly effective on these powdery mildew species when used at lower water volumes of between 500 and 800 L/ha for existing infections and 1000 L/ha for preventative applications. To obtain adequate control, applications should be made on the underside of leaves where possible and on leaves low in the plant canopy because the fungus prefers these surfaces. Takumi SC provides translaminar and vapour action which helps it move through the leaves as well as volatilise to the undersides of higher leaves.
Top tips to minimise the potential risk of resistance developing:
Do not use Takumi SC in two consecutive spray applications. Always use Takumi SC as part of a fungicide resistance programme by using products from different mode of action groups.
