TREATMENT OF WEEDS. 

 Lawns/ 



Plants like chickweed, moneywort and other running weeds can 

 be largely eradicated from lawns by treatment with nitrate of soda, 

 which should be used strong enough to kill the weeds. This may 

 also kill the grass, but a good growth of grass will come in again to 

 the exclusion of the weeds. 



Dandelions on lawns can be sprayed with iron sulphate at the 

 rate of i ^ to 2 pounds to i gallon of water. Mechanical devices 

 are also used for injecting acids and chemicals into the crowns of 

 plants like the dandelion and plantain. The midsummer application 

 of lawn fertilizers is beneficial in maintaining a strong growth of 

 grass and keeping certain fall weeds out. 



Mowings and Cultivated Fields. 



Golden hawkweed in mowings has been more or less successfully 

 treated by the application of 3,000 pounds of salt per acre. For 

 wild mustard, smartweed, pigweed, cocklebur and ragweed in oat 

 fields or mowings, spray with sulphate of iron at the rate of 100 

 pounds to 52 gallons of water. The sulphate of iron application is 

 said to cost 20 or 25 cents per acre, 52 gallons being sufficient for 



1 acre. Special spraying appliances are used for this work. Lime 

 and wood ashes are valuable for sorrel, mosses, ferns, etc. which 

 grow in acid soil. 



Tennis Courts, Walks, Etc. 



The weeds on tennis courts, grave! walks, drives, etc. can be suc- 

 cessfully removed by treatment with arsenate of soda at the rate of 



2 pounds to 10 gallons of water. This amount will cover about one 

 square rod and can be applied with a watering can or spraying 

 machine. On tennis courts in use it is generally sufficient to treat 

 only 6 or 8 feet of the edges. It can also be applied to railroad 

 beds where grass and troublesome weeds interfere with traffic. By 

 treating a strip of grass 4 to 6 inches wide close to the foundation 

 of buildings with arsenate of soda much hand trimming may be 

 obviated. Arsenate of soda is poisonous and care should be used 

 in handling it. It should not be applied too freely near valuable 

 trees. 



There are many proprietary compounds on the market known as 

 " Herbicide". " W'eedicide," etc. which are effectual weed killers.
