Arysta’s PH-D fungicide gets approval for California citrus and vegetables

Arysta LifeScience announced that the U.S. EPA and California Department of Pesticide Regulation have approved a product label expansion for PH-D Fungicide for control of Septoria spot in citrus, Sclerotinia in lettuce, and Septoria leaf spot in stalk, stem, and leafy vegetables.

PH-D is a FRAC group 19 fungicide that provides effective control of diseases that decrease crop quality and yield in a variety of fruit, vegetable, and nut crops, including almonds, grapes, pistachios, pome fruit, strawberries, potatoes, cucurbits, and fruiting vegetables. The expanded label extends the use of the fungicide to additional crops.

PH-D contains the active ingredient polyoxin-D zinc salt and controls a variety of fungi and diseases, including Septoria spot, Septoria leaf spot and Sclerotinia, which are important diseases in California crop production.

Septoria spot in citrus is caused by Septoria citri and is found on Valencia and navel oranges, lemons, and grapefruit. Sclerotinia sclerotiorum and Sclerotinia minor are prevalent diseases in lettuce production that can ultimately cause lettuce drop, a condition when the lower leaves are damaged and drop to the soil surface. Septoria leaf spot, also known as late blight, is a significant disease affecting celery production that typically occurs during cool, wet periods.
