LOOPERS, PSYLLID, THRIPS – IN ONE PASSB L A C K H A W K ® I N S E C T C O N T R O L

As temperatures warm, damaging insects go on the move. Blackhawk® insect control controls multiple pests – including loopers, psyllid and thrips – to help you protect potato yields and quality.

Pests Controlled

n Lepidopteran insects (e.g. cutworms, loopers, armyworm)

n Potato psyllid [2(ee) label]n Thripsn Colorado potato beetle

Blackhawk controls target pests through contact and ingestion, providing quick kill and residual. Pest control is consistent in high and low pressure situations and under various environmental conditions.

The translaminar movement of Blackhawk – through the leaves – can help with internal feeders and pests out of the direct line of spray.

IPM Compatibility

Use of Blackhawk will not flare mites or lead to secondary pest outbreaks. Commercial use has shown that Blackhawk has low impact on populations of key beneficial insects, including big-eyed bugs, damsel bugs, ladybugs and lacewings. There have been no reported cases of secondary pest outbreaks resulting from applications of Blackhawk.

Blackhawk® has been reviewed and registered under the U.S. EPA’s Reduced Risk Pesticide Program.

With potato psyllids, in particular, many universities recommend avoiding use of pyrethroids. Studies have shown that pyrethroids may flare potato psyllid populations by enhancing egg laying by females and/or killing beneficial insects that prey on potato psyllids. Pyrethroids also may flare aphid and mite populations due to detrimental effects on beneficial insects. Blackhawk offers an excellent alternative to pyrethroids.

Unique Mode of Action

The active ingredient in Blackhawk, spinosad, affects the insect nervous system. No other class of products – organophosphates, neonicotinoids, pyrethroids – affects the insect nervous system with the same mode of action as spinosad. Blackhawk is in the spinosyn class of chemistry (IRAC Group 5).

Summary: Trials were conducted on a research farm in Columbia Basin. Treatments were made during summer months. In 2013, four consecutive applications of each product were made. Although that is not a recommended practice in commercial situations, it allowed for better product evaluation. Blackhawk®, Transform® and Radiant® insecticides controlled psyllid nymphs and adults significantly better than the untreated plot.
