The best way to tame a wildfire is with chemicals. Di-hydrogen oxide, one of the world's most common chemicals, isn't enough. Because di-hydrogen oxide (water) evaporates too quickly. Yet combine it with di-ammonium phosphate and you have a chemical called Phos-Chek® fire-retardant. Made by Monsanto, Phos-Chek fights fire by absorbing heat and depriving fire of its fuel. A plane can drop 3,000 gallons on a fire, reload and be back in action within 20 minutes. The chemical's bright red color lets ground crews and pilots quickly locate areas that have been treated. And, when the fire's over, Phos-Chek helps fertilize the ground to promote new plant growth. No chemical is totally safe, all the time, everywhere. But if we want to protect ourselves from the rampages of nature (such as fire, famine and disease) well have to use chemicals. And use them properly. ©MonsantoCompany 1977 ------- -------------------- -------------------- For a free booklet explaining the risks and benefits of chemicals, mail to: Monsanto, 800 N.
