The Australian Pesticides and Veterinary Medicines Authority (APVMA) has approved Ishihara Sangyo Kaisha’s fungicide Kusabi 300 SC (300 g/L pyriofenone) for the control of powdery mildew (Podosphaera xanthii) in cucurbits and powdery mildew (Erysiphe necator) in grapes. APVMA also approved pyriofenone as a new active ingredient.
The proposed use for Kusabi 300 SC Fungicide will involve up to three applications to cucurbits at a maximum application rate of 500 ml product/ha and up to two applications on grapevines, at a maximum dilute spray concentration of 30 ml product/100 L.
Kusabi 300 SC Fungicide is the first pyriofenone based product to be introduced in the Australian market. The active constituent pyriofenone belongs to the aryl phenyl ketone chemical family (group U8 fungicides), which has an unknown mode of fungicidal action. This is the second fungicide with active constituent from this chemical family to be registered in Australia.
Both pyriofenone and Kusabi 300 SC Fungicide will be manufactured and formulated overseas. Kusabi 300 SC Fungicide will be available in 1 L, 2 L, 5 L and 100 L High density polyethylene (HDPE) containers.
Pyriofenone as a 300 g/L suspension concentrate is currently registered for use in France, Italy, Portugal, Hungary, Slovenia, Kosovo, Macedonia, Montenegro and Bulgaria. Applications for registration have been made in USA and Canada, with approvals expected later in 2016.
