SPRAY POTATOES TO DESTROY BUGS

To Be Made Effectual It Must Be Don 6 When Plants Are Eight or Ten Inches High. my w. M. KELLEY.) When the broods are first appearing is the time to get after the potato bugs. The best known remedy is parts green. ' To one barrel of water use threequarters of a pound of parts green and to this add about one gallon of strong lime water. This will prevent the burning of the foliage by the parts green being too strong and will also make it adhere to the leaves better. Keep the contents of the barrel well stirred while the machine is in motion. One barrel is sufficient for about two acres of potatoes. My experience with spraying as a preventative of blight has convinced me that we should begin early before the disease has appeared. Some potato growers who are the moat ready to condemn spraying wait until the disease gets a foothold and try to cure it with a strong bordeaux mixture. I believe that if spraying is to bo made effectual it must be commenced when the plants are eight or ten inches high and be continued at frequent intervals during the whole of the growing season. I have every faith in spraying as a preventative of the blight, but no faith in its application as a cure after the disease has developed. Bugs may be check by the use of the poison in the bordeaux mixture, and when we consider this advantage it is plain to see that the cost of the applied fungicide is very much lessened.
