Syringe all parts with a solution at the rate of $ oz. to 



a gallon of rain-water. In the case of young plants 



dip them in the solution. 

 Scatter the powder on the affected parts. 

 Place 4 oz. soft soap in 2 quarts water ; boil for twenty 



minutes, then add 2 oz. sulphur and 2 oz. lime, boil 



for ten minutes more. Use a wineglassful to 1 gallon 



clear water, and syringe the plants. 

 Too much moisture at the roots after the repotting and 



the use of too strong manures aggravate this evil. 



Keep soil drier for ten days or so.
