On June 3, 2020, the U.S. Court of Appeals for the Ninth Circuit issued a ruling that vacates current U.S. registrations of of three dicamba herbicides, XtendiMax (Bayer), Engenia (BASF) and FeXapan (Corteva). The Court ruled in favor of a petition challenging the EPA’s 2018 registration decision. The ruling comes after a group of environmental organizations filed a petition with the Court challenging the U.S. Environmental Protection Agency’s . Other dicamba-containing products are not concerned by this ruling.
The subsequent action by the EPA provides, among other things, that “growers and commercial applicators may use existing stocks that were in their possession on June 3, 2020, the effective date of the Court decision. Such use must be consistent with the product’s previously-approved label, and may not continue after July 31, 2020.”

The EPA’s order addresses the use, sale, and distribution of existing stocks of low-volatility dicamba products impacted by the Court’s ruling.
Peach:
Oriental Fruit Moth: We are between generations 1 and 2, with the first insecticide applications due in southern counties in 10 days to 2 weeks. Where trap captures are below 8 moths per trap and no injury is present, then stretch insecticides to get as close to the model timing as possible. Where trap counts continue above 8 males per trap, then the population is too high to take this approach. This is the case in several orchards in northern counties. [Read more…]

Plum Curculio (PC): PC oviposition is coming to an end in most counties. The Cornell model recommends that insecticides are only needed until 308 DD base 50 after apple petal fall. This was June 1 in southern counties and should be about June 5 in Hunterdon County and slightly later north of Pittstown. Therefore applications made this week in southern counties should control this generation of PC. In the southern part of the state we also have the southern strain PC, which has 2 generations per year. Therefore this may be a returning issue in mid-summer.
