Kontos is a new systemic insecticide that is both xylem and phloem active, meaning the active ingredient moves upward and downward in treated plants, according to Dr. Richard Lindquist, OHP senior technical manager. “Kontos can be applied as a foliar spray or drench and controls a number of major sucking insect and mite pests, including aphids, leafhoppers, mealybugs, psyllids, spider mites, and whiteflies,” notes Dr. Lindquist.
Kontos, with active ingredient spirotetramat, is the first systemic insecticide with activity on spider mites, adds Dr. Lindquist. A member of the tetramic acid class (Mode of Action Group #23), Kontos is a lipid biosynthesis inhibitor and is active primarily through ingestion. “Kontos is a unique product on a couple of levels,” notes Dan Stahl, OHP vice president of marketing and business development. “First, it is a systemic product that has activity on spider mites.
That’s a real plus for the grower,” says Stahl. “Second, it is a different class and mode of action than the neonicotinoid class, which has been widely and effectively used the last several years,” says Stahl. “Kontos provides a rotational tool for those growers who have been using neonicotinoid drenches and want to change things up. It’s a great alternative.”
The neonicotinoid class of products (MOA Group #4A) includes Marathon®, Safari®, Flagship®, and TriStar®. Kontos is labeled for use on vegetable transplants and for use through irrigation systems, and is soft on many beneficial insects and mites, notes Stahl. Kontos is a suspension concentrate (SC) formulation and is packaged in 250 mL bottles.(8.45 oz) Usage is 1.7 to 3.4 oz per 100 gallons. (1/8 to 1/4 tsp per gallon)
