| Question: | "We have been applying arsenic acid (75 per cent) with the power sprayer at the rate of ½ pint in 50 gallons of water to cover 1,000 square feet of turf to control chickweed. It has burned the clover out and injured dandelions and broadleaf plantain. There has been considerable burning of the turf however. Has our rate of application been too heavy?" |
| Source of Question: | Massachusetts |
| Answer/Response: | "Arsenic acid is a heavy liquied therefore 1 pint of it weighs almost 2 pounds. You can roughly figure it on a 2-pound basis. Therefore, you were applying the material at the rate of 1 pound to 1,000 square feet. This is a very heavy application as a spray and would be expected to cause some injury to the grass. It has been our experience that the best results are obtained when arsenic acid is applied in the form of a spray at the rate of ¼ to ½ pound to 1,000 square feet. The ¼-pound rate is usually ample to give fairly good control and does not cause a great deal of damage to grass. In the case of the bent grasses, the rates have been reduced to 1 or 2 ounces to 1,000 square feet. However, when these light rates are used, it is necessary to repeat the treatment at least two or three times to get a reasonably good control of the weeds. Even though you have considerable burning of the grass, you no doubt will find that most of it will recover. The amount of water which you used is much more than we ordinarily find necessary for complete coverage." |
