Aug 2, 2018California OKs fungicide’s new label for lettuce, other veggies
The EPA and California Department of Pesticide Regulation (CDPR) 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 from Arysta LifeScience 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.
David Davies, Arysta’s U.S. Fungicides and Herbicides Marketing Manager, described PH-D as having a mode of action unique among fungicides.
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.
“Arysta LifeScience recommends that growers apply PH-D at the crop stage indicated on the product label for each crop and then rotate to fungicides with other modes of action as part of their resistance management strategy,” Davies said.
