Arysta LifeScience North America recently received a supplemental label for PH-D fungicide in the state of California.
PH-D is a broad-spectrum, Group 19 fungicide. Its unique mode of action makes it an ideal addition to a rotational program to aid in resistance management as it works by preventing cell wall construction via chitin inhibition by enzyme interference. PH-D should be applied preventatively, particularly when climatic conditions exist for disease development.
For control of Alternaria spp and Botrytis spp and suppression of Botryosphaeria spp, the PH-D label in California now includes the following crops:
• Berry and small fruit
• Fruiting vegetables
• Pome fruits
• Root and tuber vegetables
• Leaves of root and tuber vegetables
• Stone fruits
• Tree nuts
• Grapes (for Alternaria)
“Arysta LifeScience is proud to bring the science and technology of PH-D Fungicide to California for use on additional crops,” said Carmen Holding, marketing manager, Arysta LifeScience. “Adding more crops to the label gives California fruit and vegetable growers another tool in their management plans to help grow strong, healthy trees and plants.”
