| Ministers were advised last July to recall dozens of household insecticides containing the chemical dichlorvos, because of new evidence that it could cause cancer. |
| Experiments in greenhouses and food storage areas show that 90 percent of the applied dichlorvos disappeared in three to six hours. |
| In the environment, trichlorfon degrades to dichlorvos, which is also an organophosphate. |
| Do not use in conjunction with products containing trichlorfon or dichlorvos. |
| Lure can either be mixed with an insecticide or a piece of paper dipped in dichlorvos can be placed in the trap. |
| But it was recently found that some ham manufacturers here were so blinded by greed that they spread dichlorvos, a pesticide, on the ham so that flies would be kept off it. |
