ground. This method is very rapid and a considerable area can be 

 covered in a few hours. Rake all plants together and burn. Burning 

 is necessary because the seed frequently matures sufficiently in drying 

 to fall from the head. Such seed is just as viable as fully-matured 

 seed. 



It is not advisable to pull up plantains by hand, as the root system 

 is so large that considerable damage will be done to the surrounding 

 grass. In cases of very serious infestation it may ])e advisable to 

 resort to spraying. For this the most commonly used material is iron 

 sulphate, 40 pounds to 25 gallons of water. Spray with a small hand 

 sprayer, using as much force as possible.

There have been several other chemical remedies recommended wliich 

 might prove equally as satisfactory, such as bluestone, 2 pounds to 

 9 gallons of water. A teaspoonful of common salt applied to each 

 plant is a very effective remedy and does not materially affect the 

 grass. 



If spraying is tried the lawns should not be watered for at least 

 24 hours. The best time to spray is in the morning. The grass will 

 probably turn a little brown, especially if the work is thoroughly done, 

 but this will do no harm. Follow the spraying, after 24 to 48 hours, 

 with a good raking, and then apply a light dressing of fertilizer. 

 The lawn will respond with renewed vigor and will be free from weeds.
