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).

Limitations, Restrictions, and Exceptions


To control crawling and flying insects in sites that include, but are not limited to, homes, restaurants, food processing plants, industrial installations and warehouses, Pyrenone Crop Spray may be diluted with water and applied as a space spray. For best results, close doors and windows before spraying and keep them closed for 30 minutes after treatment. The applicator must vacate the area after treatment and ventilate before reoccupying. Where oil residues are not undesirable, Pyrenone Crop Spray can be diluted in light mineral oil instead of water and applied with mechanical, thermal or ULV applicators.

The use of this product in food processing or food handling establishments must be confined to time periods when the plant is not in operation. Foods should be covered or removed during treatment.

Food processing surfaces and equipment must be covered during treatment or cleaned with a suitable detergent and rinsed with potable water before reuse.

FLYING INSECTS: For control of Flying Insects Including, dilute 1 part of Pyrenone Crop Spray with 47 parts of water or oil (2.67 ounces per gallon) and apply at the rate of 1 ounce per 1000 cubic feet of space. Direct the spray towards the ceiling and upper corners of the area and behind obstructions. Vacate the treated area and keep the area closed for at least 30 minutes after treatment. Ventilate the area before reoccupying. Repeat treatment as necessary.
