(2) For control of Johnsongrass : Dalapon at 10 to ZO pounds applied in 20 

 to 40 gallons of water per acre when the grass averages 15 inches in height, 

 and follow^ed by disking in 2 weeks has proved effective. 



Spot spraying in cultivated row crops .--Spot spraying with dalapon at 

 1/4 pound per gallon of water, or TCA at 1/4 to l/2 pound, about once a 

 month during the growing season will effectively control small patches of 

 Johnsongrass or Bermudagrass in row crops. Aromatic oils and dinitro- 

 fortified fuel oils also can be effectively used in the same manner. Damage 

 to crops in the treated areas usually will not exceed that caused by hand 

 hoeing heavy weed infestations.

 weed is 12 to 18 inches tall.
