Lorsban (32) (chlorpyrifos) is an organophosphate insecticide that that was previously registered for use on apples, cherries, peaches, nectarines, grapes, cranberries and strawberries.  Effective Oct. 29, 2021, the U.S. Environmental Protection Agency (EPA) has revoked all tolerances for residues of chlorpyrifos for all food and feed commodities, which expired on Feb. 28, 2022.

Onager (42) (hexythiazox) is a miticide for control of European red mites and twospotted spider mites on apples, cherries, peaches, plums, grapes, strawberries and caneberries. It is an active mite ovicide and larvicide, providing control ranging from 10 weeks to full season, depending on mite pressure, the extent of vegetative growth and predator mite populations. Control is achieved when eggs come into direct contact with the spray or contact with treated plant surfaces. It is considered not toxic to predator mites. Onager can be applied ONLY once per year with a maximum of 24 ounces (32 ounces for caneberries and strawberries).

Kanemite (68) (acequinocyl) is a miticide labeled for use in apples, pears, cherries, blueberries, caneberries, hops and strawberries for the control of tetranychidae mites (spider mites and red mites), providing control ranging from six to eight weeks depending on mite pressure, the extent of vegetative growth and predator mite populations. This miticide has a novel mode of action but should be limited to two applications per year or a total of 62 fluid ounces.
