Rendering powdery mildew powerless
Powdery mildew is a threat to all Australian grapevines – and most cucurbit crops – every season. Many products are registered to treat it, but only Vivando® ‘disarms’ the disease spores by disrupting development of the tips that allow them to penetrate plant tissue. That entirely different mode of action prevents the infection taking hold. Rainfast in just one hour, Vivando has both contact and vapour activity. That results in improved coverage of foliage and fruit, even in tight clusters.
The active ingredient of Vivando®, metrafenone, is the first agent from the benzophenone chemical class to be developed and Vivando is the first fungicide in a new group: Group U8.
Vivando stops infection by inhibiting spore penetration into the plant tissue and limiting sporulation. It also limits lesions by slowing the growth of existing powdery mildew infections. Smaller lesions reduce the spread of the infection.
Vivando is released by vapour pressure, which can help spread the active across the leaf or fruit surface. That distributive action maximises the protective area in all crops and is particularly advantageous in protecting tight bunches of grapes.
