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


USED ALONE: Pyrenone Crop Spray is designed for use on minor crops and as a pre-harvest spray when other materials cannot be used due to pre-harvest interval restrictions. Pyrenone Crop Spray may be used up to and including the day of harvest. Apply up to 0.05 pounds of pyrethrins per acre and repeat as required to maintain effective control. Use the calibration chart listed in the label to calculate the desired application rate. Use in sufficient water for thorough coverage of upper and lower leaf surfaces.



Pyrenone Crop Spray may be combined with other insecticides for quicker and more complete control and as an exciter to flush insects out of hiding and into contact with spray residues. The application must conform to the accepted use precautions and directions for both products. Pyrenone Crop Spray may be tank-mixed at rates of up to 0.05 pounds of pyrethrins with the amount of companion insecticide specified for one acre.

Prior to tank-mixing, a small jar compatibility test should be conducted using the proper proportions of chemicals and water to ensure the physical compatibility of the mixture.

Tank-mix applications must be made in accordance with the more restrictive of label limitations and precautions. No label application rates may be exceeded. This product cannot be mixed with any product with label prohibitions against such mixing.
