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


AS A GRAIN AND SEED PROTECTANT: Pyrenone Crop Spray may be applied to the following grains and seeds: barley, beans, birdseed, buckwheat, cocoa beans, corn, cottonseed, flax, oats, rice, rye, sorghum and wheat to protect them from grain storage insects for a full season or approximately 8 months. Pyrenone Crop Spray may be used in combination with a registered fumigant for use on heavily infested stored products.

SURFACE TREATMENT OF STORED GRAIN AND SEED: To control Indianmeal moths, Angoumois grain moths, and Mediterranean flour moths, monthly inspections should be made after the grain is placed in storage. If the top two or three inches are infested, dilute 1 part of Pyrenone Crop Spray with 19 parts of water and apply at the rate of 1 to 2 gallons per 1000 square feet of grain. Rake the mixture into the grain to a depth of 4 inches.
