The protectant mancozeb fungicides Quell Flo and Laminator FL have new specific off-label approvals (SOLAs) for use on onions and shallots, adding to the limited number of fungicides that are recommended in these specialist crops. Quell Flo and Laminator FL will protect primarily against downy mildew and have a bonus effect on other diseases such as Botrytis.
Dr David Stormonth, technical manager for chemical provider Interfarm UK, said that with continuing global problems in the production and supply of Dithane 945 and Dithane NT, these new SOLAs offer growers alternative solutions in the form of Quell Flo/Laminator FL.
“Both Quell Flo and Laminator FL are suspension concentrates of mancozeb and are registered for the same crop range as Dithane products,” he said. “As liquid formulations, Quell Flo/Laminator FL disperse easily in the spray tank and have no problems of dust. The active ingredient mancozeb is recommended on more than 70 different crops for the control of more than 400 diseases globally and is regarded as a very cost effective protectant fungicide. As a multi-site fungicide, it also offers an anti-resistance component to any spray programme.”
