Controlling diseases such as Powdery mildew and Botrytis bunch rot in grapes is a season-long endeavor that takes an integrated approach and multiple fungicide applications. The potential for pathogens to develop resistance to commonly used fungicides is always a concern.

Arysta LifeScience works diligently to register and introduce crop protection technologies in new markets, including grapes. One example is PH-D® Fungicide, a trusted tool for use against diseases caused by various fungi. PH-D provides control of Bunch rot organisms such as Botrytis and Cladosporium as well as having burndown activity against Powdery mildew. And because PH-D features a unique mode of action, it’s the perfect addition to a rotational program to aid in resistance management.

The unique mode of action of PH-D prevents fungal cell wall development via chitin inhibition by enzyme interference. This unique mode of action makes PH-D a smart addition to a rotational management program when multiple applications are required.

PH-D has proven to be an effective disease protection tool in many crops, including grapes. PH-D is a broad-spectrum Group 19 fungicide featuring a 4-hour re-entry interval (REI) and a 0-day pre-harvest interval (PHI). PH-D should be applied preventatively in grapes, particularly when climatic conditions exist for development of disease.

The skilled grape grower will use a combination of fungicide treatments and appropriate cultural practices to give grape vines a solid foundation. When combined, PH-D and VITICURE® Fungicides are two proven products that offer protection against Powdery mildew and can be used as part of a disease management plan to keep grapes healthy and thriving all season long. PH-D and ELEVATE® Fungicides work together to protect vines from the potentially devastating effects of overwintering Botrytis bunch rot.
