When applying 2,4-D postemergence use a relatively high amount of water per acre and 

 a pressure level that is as low as possible. A pressure of 20 pounds per square 

 inch with regular, flat-fan nozzles will give adequate coverage. 



If it is absolutely necessary to spray 2,4-D in the vicinity of susceptible crops, 

 use flooding-type nozzles and low pressures. These nozzles give adequate coverage 

 of broadleaf weeds at pressures as low as 10 pounds per square inch. 



Be especially careful when spraying 2,4-D near residential areas. It may be best 

 simply not to spray the rows nearest such areas. 



Spray only when the wind velocity is low- -under 5 miles per hour if possible. If 

 spraying is to be done near susceptible plants, do it when the wind is blowing away 

 from the plants .
