Update on Pesticides for Tender Fruit, 2021

Tender fruit growers face some challenges with the results of PMRA re-evaluations of some products but there are new options available as well in 2021. In collaboration with Ryan Brewster, Brewster Consulting Services Inc., this post provides a list of changes for 2021.

Most of the changes listed in this post have been incorporated into Publication 360D. However, any additions or changes made after October 2020 did not make it into the book.

Last farm use

The following products cannot be used after the last farm use in the table below.

Lorsban is still registered for use in peaches for Oriental Fruit Moth; however, it is no longer being produced.

Label changes as a result of re-evaluation

Only WSP or SC formulations of captan will be available for sale in 2021.  Existing supplies of captan products may be used according to the existing label only until May 1, 2021.  New restrictions for use of captan products with respect to rate, number of applications per year and restricted entry intervals (REI) are listed in the table below.

Sharda Captan 48 SC is a new formulation of captan that will be available in 2021.  The recommended use rate for apricot, cherries, peach, nectarine and plum is 6.6 L/ha with the same REI as the other captan formulations.  It is not labeled for use on pear.

New products and additions to Publication 360D, 2021

As a result of reclassification by the Fungicide Resistance Action Committee, Fracture and ProBLAD are now BM1 and Double Nickel and Serenade OPTI are BM2. BM = Biological with multiple modes of action.
