Applications should still kill the dandelions and may prevent formation of the 

 seeds. Apply these materials when there is no wind blowing; even light drift of 

 spray onto susceptible shrubs, flowers, and vegetables may seriously damage such 

 plants. 



Precautions in Using Pesticides 



Each year we get a few reports of spray solution with pesticides siphoning down 

 into wells from sprayer tanks. Watch the hose when filling, or attach it to the 

 top of the tank so it will remain above the water level. Remove the hose as soon 

 as the tank is filled. The proper use of valves on the water system car- also help 

 prevent the possibility of such siphoning. Prevention is a lot easier than ef- 

 fecting a cure. 



Keeping good records of pesticide applications is like keeping a good record of 

 your checking account. It provides a valuable review and helps in making future 

 plans. 



Always keep pesticides out of the reach of children and people not accountable 

 for their actions. These are the ones who most often suffer from improper pesti- 

 cide storage.
