General Information

For any requirements specific to your State or Tribe, consult the agency responsible for pesticide regulation.

Pyrenone Crop Spray is relatively non-toxic to Honey Bees. To maximize this benefit, apply early in the morning or late in the evening.


Refer to supplemental labeling entitled DIRECTIONS FOR APPLICATION THROUGH IRRIGATION SYSTEMS (available through your distributor) for use directions for chemigation. Do not apply this product through any irrigation system unless the supplemental labeling on chemigation is followed. Pyrenone Crop Spray may be used on most crops because its active ingredients are exempt from tolerances when applied to growing crops. The crop grouping scheme used on the label was devised by the Environmental Protection Agency to expedite minor use pesticide registration. Each crop grouping on the label contains the phrase “including, but not limited to,” and then lists a number of crops in each group. This wording allows the use of Pyrenone Crop Spray on crops that may not be specifically listed on the label (providing that the group to which the crop belongs is listed).

Apply only when flying insects are present. Several applications may be necessary during periods of heavy infestation, but do not make more than 10 applications.
