Mix the 6 quarts Roundup" in the 120 gallons of water and proceed to 

 spray at the speed and pressure determined earlier. The procedure is the 

 same for other herbicide formulations. Read the label! 



Calibrate your sprayer often. Nozzle tips wear, pressure gauges fail, 

 pumps wear, and screens clog. Keep a record of pressure, speed, and sprayer 

 output for later reference. 



Calibration of sprayers is one of the steps in proper use of agri- 

 cultural chemicals, an important step. Improper calibration wastes product 

 and money, pollutes, and may cause crop injury. 



Take time to calibrate often and accurately.

Harvesting Empire apples from interstem trees . While harvesting 

 Empires from interstem trees last fall two thoughts came in mind. 

 Harvesting apples from low limbs on dwarf trees is "hard" on the back. 

 Secondly, it is very necessary to eliminate most of the grasses and weeds 

 under these trees because of fruit shading. In the planting being harvested 

 a high percentage of the fruits on many low limbs were culls because of ina- 

 dequate color.
