New fungicides labeled for use in tree fruit - all Special Local Needs Labels

Summary of New fungicides, by David Rosenberger
The SDHI fungicides Fontelis, Luna Tranquility, and Merivon are effective against scab, rust, and mildew, but only Fontelis and Luna Tranquility are currently registered in NY (via special local needs labels), and none of these products are labeled on Long Island due to concerns about the potential for ground water contamination. Merivon was the most recent to receive a New York label. Fontelis is labeled for use on apple and pears, cherries, peaches, plums and strawberries. Luna Tranquility is labeled for use on apples. Merivon is labeled for use in pome fruit and stone fruit.For early-season disease control in apples, these products are best used between tight cluster and first cover. Our preference is to use them before petal fall. That is especially true for Luna Tranquility, which is a premix of Luna (the SDHI component) and Scala (pyrimethanil). Scala alone is not effective in protecting fruit from scab or in controlling rust, and the Luna component, like many of the SDHIs, has only moderate activity against rust diseases. Controlling cedar apple rust on leaves is usually most difficult during the period of rapid shoot growth after petal fall, so Luna-T is does not fit very well after bloom.
All of these SDHI fungicides should be applied in combination with either mancozeb or captan. This is essential for both fungicide resistance management and because the SDHI fungicide products may not redistribute well enough to protect newly expanding leaves that develop between sprays. In most cases, we prefer to see these products combined with mancozeb rather than captan because of the additional rust control provided by mancozeb and because Fontelis, which is formulated with mineral oil, can enhance uptake of captan into leaves and fruit where captan will cause injury under certain environmental conditions. Merivon has label warnings against tank mixing with oil sprays or other pesticides formulated as emulsifiable concentrates.
The labels are in the Special registration section of the PIMS website.
