Old Pesticide: Is It OK to Use? 



You purchased chemicals some time ago. Now you realize they are two 



years old. You also bought one product, that you heard was going off the 



market, so that you would have a supply to last you several years. We get 



calls all the time about what you can do with the old stuff you have in your 



cabinet. Products you don't use because of a crop change, etc. 



All products sold, and or used, must be registered in your State. You are 



subject to inspection and control of theproducts in your cabinet regardless 



of when you bought it. One grower was told not to use a product he had 



because it was not registered with the State at the time the inspector found 



it. Sometimes the age has nothing to do with iL It could be that the 



manufacturer didn't bother to do his job or wasn't told it was going into 



your State. What a pain in the neck when all you want to do is bring a crop 



to market. 



Therefore, we suggest that you . . 



Buy only what you need, when you need it. 



Rememben the best way to get rid of pesticides is to use them up in 

 accordance with the lable.
