Control tips: Clean and spray grain bins with Diacon® IGR and Centynal™ Insecticide tank mix prior to grain storage. Inspect and treat incoming grain with Diacon® IGR; monitor grain throughout storage period.
Application tips: When treating flowing grain on belts or at transitions, 2 or more nozzles are recommended; during auger or conveyor cup application, fewer nozzles may be used; Position nozzles for full coverage of grain stream; avoid spraying onto sides of auger boots. Calibrate protectant flow rate and check often to help ensure proper application. Use automated switches to turn chemical pumps on when there is grain in the system and turn off when no grain is present.
