Sequoia® CA Insecticide Registered for California Tree Nuts

(July 26, 2020) Corteva Agriscience has received California Department of Pesticide Regulation approval for Sequoia® CA insecticide in tree nuts, including almonds, pistachios, walnuts and pecans.  Labeled insects include aphids, San Jose scale and Gill’s mealybug (2ee label).

Sequoia CA contains the active ingredient Isoclast® active, a member of the sulfoximine class of chemistry.  “In tree nuts, Sequoia CA will be the only insecticide designated as a member of the new subgroup 4C by the Insecticide Resistance Action Committee,” says Jeff Pacheco, Corteva market development specialist.  “It has a different mode of action from other insecticides in tree nuts, which will make an excellent rotation partner in full-season IPM programs.”

“Sequoia CA will be valuable addition to the limited number of insecticides used for Gill’s mealybug in pistachios”, says Pacheco.  “That insect continues to spread in California orchards and many growers are battling it for the first time.  Corteva and university field trials have been conducted in California since 2013, and Sequoia has shown good control of Gill’s mealybug, especially when applied at the crawler stage”, says Pacheco.

In walnuts and pecans, Sequoia CA will be an excellent product for aphids.  “Pecan growers outside of California have been using the product for several years, and it has become an important part of aphid management programs.  And for aphids, in general, Isoclast active has been widely-used in other crops including leafy vegetables, cole crops and cotton.”

Sequoia CA will fit well into IPM programs that rely on beneficial insects.  “Field trials and commercial use on various crops show that Sequoia has low impact on populations of beneficial insects,” says Pacheco.  “And it won’t flare mites or secondary pests.”
