20 Cylinderized Phosphine Fumigant History What makes PHOSPHINE a good fumigant? Highly toxic to wide variety of insects Highly mobile gas Excellent penetrating ability in commodities Very low residual properties Environmentally responsible Non ozone depleting nor a greenhouse gas Comparison to traditional forms of Phosphine fumigants AlP, MgP solid formulation properties: Fire hazard- reactive to water and humidity Produce dust residues and waste materials requiring disposal Can be slow in achieving lethal dosage throughout commodity May require confined space entry scenarios How to maximize the benefits of phosphineas a fumigant? Use phosphinegas in a more direct approach The evolution of cylinderized Phosphine Fumigants 20

21 Comparing Cytec Phosphine Fumigants with Metallic Phosphides Non Flammable Does not react with moisture or water No Waste Disposal No dust residue or pre-pacs to collect and deactivate No disposal or waste material Reduced Worker Exposure No direct contact with fumigant pre or post fumigation No confined space entry to add fumigant No Risk of reacted or partially reacted material left in Commodity Reduced Fumigation Times Save at least 24hrs Reduced Dosage Levels Control dosing allows for use of less gas High Quality- Purity and Consistency Manufactured in Canada 21

22 Benefits of having Phosphine in gas form 1. External application Eliminate Confined Space Entry Reduce worker exposure Eliminate retrieval of partially spent fumigant 2. No waste by-products or residues No waste deactivation or disposal 3. Environmentally friendly Non Ozone Depleting Non-Phyto-toxic- opens new opportunities Decrease Amount of PH 3 Applied Lower Dosages 4. Ease of Application and Control Quick establishment of lethal concentrations Effective control of target insects SAFER GREENER FASTER 22

23 Worker Exposure-Waste Handling ELIMINATE REMOVAL,DEACTIVATION & DISPOSAL of partially spent fumigants 23
