Vivando fungicide from BASF Crop Protection has received full registration from the U.S. Environmental Protection Agency and the California Board of Pesticide Regulation. The new fungicide is highly effective for control of powdery mildew in wine, table and raisin grapes.
"Vivando will be an important addition to the grape grower's disease control arsenal," says William Strickland, BASF Vivando Marketing Manager. "The active ingredient, metrafenone, is the first fungicide to be developed in its chemical class, giving growers a new way to fight yield-robbing powdery mildew."
The active ingredient is lipophilic, and as such, it is very easily absorbed into the waxy cuticle layer that surrounds the exterior cells of a plant to prevent water loss.
Also, extensive research has shown that Vivando does not exhibit cross-resistance to any of the known fungicide modes of action. Studies have shown that this active ingredient disrupts normal distribution and functioning of actin in powdery mildew cells, destabilizing the growth process.
In addition it controls powdery mildew at three different stages of the fungal life cycle:
"We looked at Vivando trials here in California with extreme powdery mildew situations and I was really impressed," says Clay Houchin, Sales Manager, Buttonwillow Warehouse Company. "Vivando really stood up against its competitors and the fact that Vivando offers a new active ingredient makes it a great rotational product."
Rotational treatments continue to be an important factor in managing resistance. Apply any time from pre-bloom to pre-harvest. It helps to safeguard the yield and quality of grape crops when applied preventatively and in rotation with other modes of action such as the strobilurin and carboximide in Pristine fungicide.
