A lot of people have been telling me how well Tempo works on their vegetable gardens and places where they prepare and store food. I have used Tempo around the outside of grain bins, building foundations, and places where people don't hang out. I have read labels for several Tempo products by Bayer and none of them are approved for use on things you eat. The only reason they're allowed in places where food is prepared is normally the food is not prepared on the floor of a food plant or processing facility. The food should not be coming in contact with an insecticide that's been applied in those places.
I called Bayer today and asked for some input and they said by no means should it be applied to anything you eat or any surface you use to process or serve food. Anyone that's putting Tempo on their garden is whacked. Sure it does a great job killing a whole bunch of insects and it has a long residual life, but that's all the more reason not to eat it.
I'd suggest finding products better suited to gardens. Sevin and Malathion are my choices. Both are approved for use on vegetable and fruit plants. Both are usually available from Steadman's, or if you prefer, WalMart. Don't be eating Tempo.
