New option for powdery mildew control for tomato growers

Certis’ powdery mildew fungicide, Takumi SC, has been granted an ‘Extension of Authorisation for Minor Use’ (EAMU) to allow applications to be made to glasshouse tomato crops.

Certis’ powdery mildew fungicide, Takumi SC, has been granted an ‘Extension of Authorisation for Minor Use’ (EAMU) to allow applications to be made to glasshouse tomato crops. 

Dr Phil Morley of the Tomato Growers’ Association, believes that the new off-label approval for Takumi SC provides tomato growers with an alternative option for the prevention and treatment of powdery mildew.

“This EAMU is a welcome development for the tomato industry, offering a much needed additional control option for Mildew,” says Phil. “The active ingredient cyflufenamid has protectant and curative properties, and will offer growers effective and locally systemic control (or translaminar activity) giving long term protection on treated leaves.”

He explains that the main control option currently available for use against powdery mildew in glasshouse tomato crops is sulphur. “A significant problem with the use of sulphur based products is their effect on the biological control of Glasshouse Whitefly. As a result, growers are often required to use a secondary product to reduce pest populations.

“The existing products can therefore be very disruptive within the glasshouse ‘ecosystem’ and are not compatible with existing integrated pest management (IPM) systems.” 

Alan Horgan, Certis’ Technical Officer notes that Takumi SC has a novel mode of action that provides a much needed solution in the ongoing battle against this damaging disease. “Powdery mildew can be a devastating fungus to treat, causing stunted growth, amongst other problems.”

He advises employing the maximum individual dose is 150ml per hectare for tomato production. Growers can make two applications per crop providing the maximum total dose of 300ml per hectare isn’t exceeded and providing that the three day harvest interval is observed.

Before use, growers should test Takumi SC on a small area of the crop to satisfy themselves regarding crop safety on the species and variety requiring treatment.

Growers should also obtain a copy of the notice of approval via the Chemicals Regulation Directorate (CRD) website www.pesticides.gov.uk.

Disclaimer: This extension of the authorised use provides for the use of Takumi SC in respect of crops and situations, other than those included on the product label. No efficacy or phytotoxicity data have been assessed and as such the ‘extension of use’, is at all times done at the user’s choosing, and the commercial risk is entirely theirs.
