Danitol is a not a new insecticide but it is new to the cranberry industry. It was registered in 2020 on cranberry and is the first pyrethroid registered on cranberry. It is registered for use in Wisconsin on several crops including pome fruit, stone fruit, grape, bushberries, and low-growing berries, including cranberry. It is marketed by Valent® under the formulation 2.4 EC (2.4 lbs of active ingredient per gallon as an Emulsifiable Concentrate). Danitol is in the class of the pyrethroids (IRAC group 3), which have a mode of action that targets the sodium channels in the neurons. Pyrethroids cause a prolonged depolarization of the neuron from a prolonged influx of sodium into the neurons, leading to repetitive nerve activity that can result in hyperexcitation, paralysis, and death. The active ingredient in Danitol is fenpropathrin. Danitol is an insecticide with foliar activity that is fast acting by contact or ingestion of treated plant surfaces. Affected insects will rapidly stop feeding, become paralyzed, and eventually die.

Danitol has broad spectrum activity on many insect species and under the low growing berries (13-07G) which includes cranberry, Danitol is registered to control a long list of insects. Despite this long list, the only insects listed that are pests in Wisconsin cranberry are leafhoppers. In our trials, Danitol was shown to be very effective on leafhopper nymphs and adults and more trials will be conducted to assess its efficacy on blunt-nosed leafhopper more specifically.

Danitol may be applied by ground equipment, chemigation, and air and buffer zones from aquatic habitat are specifically stated in the label and vary based on the mode of application. For more information on mixing and spraying, and all other considerations, please see the product label.

Danitol is highly toxic to bees exposed to direct treatment or residues on blooming plants. Do not apply Danitol when bees are foraging and until flowering is complete. Danitol is extremely toxic to fish and aquatic organisms and must not be applied directly to water. Danitol is also toxic to wildlife.

Please check with your handlers before using a new product as handlers may not allow certain products for domestic and/or foreign markets. Also handlers may extend PHIs from the one stated in the label to reduce residues so please always check with your handlers. As always, make sure to read the label before using any pesticide.
