The best candidate for the toughest job
Of all the products registered to control powdery mildew, Vivando® is the outstanding current choice to build a program around. Vivando prevents powdery mildew spores from penetrating the plant tissue by ‘disarming’ them – disrupting development of the piercing tips. That novel and advanced mode of action, with no cross-resistance to other chemistry, provides robust protection of even the most susceptible grape varieties. Vivando can also be used to extend pumpkin and squash protectant programs out to 14 days before harvest.
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.
