Vegetable insecticide update

Several more vegetable crops have been added to the list of crops on which Exirel and Verimark can be used. These contain the active ingredient cyantraniliprole, also known as Cyazypyr. This is in the same chemical group as Coragen and Altacor. The changes are summarized below. Full details are found on new supplemental labels.

Exirel is for foliar sprays, and can now be used on potatoes and other tuberous/corm vegetables; snap beans and other legume vegetables; radish, carrot, and other root vegetables; as well as on greenhouse-grown cucumbers. Crops already on the older federal label for Exirel are cabbage, kale, and other Brassica vegetables; green onion, bulb onion, and other bulb vegetables; cucumbers and other cucurbits; tomato, pepper, and other fruiting vegetables; lettuce and other leafy vegetables, as well as greenhouse-grown tomato, pepper, and eggplant. Target pests are caterpillars, aphids, flea beetles, whiteflies, leafminers, Colorado potato beetle, and thrips.

Verimark is for soil applications, and can now be used on green onion, bulb onion, and other bulb vegetables; snap beans and other legume vegetables; radish, carrot, and other root vegetables. Crops already on the older federal label for Verimark are cabbage, kale, and other Brassica vegetables; cucumbers and other cucurbits; tomato, pepper, and other fruiting vegetables; lettuce and other leafy vegetables; potatoes and other tuberous/corm vegetables.

Belay has a new label that no longer includes several vegetable crops that were on the previous label. The new label also has some new restrictions. Belay is a neonicotinid that contains the active ingredient clothianidin. Growers who have existing stocks of the old product with the old label are allowed to use it as detailed on the old label, but all new product purchased this year will have the new label. Belay can no longer be used on tomato, pepper, eggplant, or other fruiting vegetables. Use of Belay on cucurbits and potato is still allowed, but with modified directions for use. On cucurbits, the previous label for foliar applications specified to not apply within 7 days of harvest; the new label does not specify a number of days, but that applications must not be made after the 4th true leaf on the main stem is unfolded. On potato, the pre-harvest interval remains as 14 days, but restrictions now include not applying treatment between 50% row closure and petal fall, and not making more than one application per year prior to 50% row closure.
