STATE BOARD OF AGRICUL-TURE. 



Seed potatoes should be selected from healthy productive typical 

 hills. The causes for decreased yields are due probably to the presence 

 of Mosaic, Leaf Boll, or Curly Dwarf which should be removed from 

 the seed plot. These troubles are undoubtedly transferred from dis- 

 eased plants to healthy plants by insects such as leaf hopper, potato 

 beetles, and other insects. The use of bordeaux mixtures and arsenicals 

 can be used to repell and destroy such insects. Black Leg and Fusarium 

 Wilt can be eliminated by rogueing, while Bhizoctonia (Black Scurf) 

 and Scab can be controlled by treating the seed with corrosive sublimate. 

 If these operations are followed carefully it w^ill be possible to secure 

 a much higher yield of potatoes.

 sulting yield of a different potato, each of which when planted in the spring weighed 

 eight ounces, and which was cut in four pieces and planted the saane distance apart. 



By selecting enough of those healthy hills showing a normal growth, 

 having desirable type and producing good yields, and then planting 

 them in a seed plot in a section of the general field, a sufficient supply 

 of good seed can be secured for your general planting every year. 



SUGAR BEETS*. 



In certain sections of the Upper Peninsula, notably the southern 

 portion, the sugar beet has long been considered one of the good cash 

 crops for the farmer to grow. At Menominee is located one of the 

 largest isugar factories in the State. This insures a ready and close 

 market for all beets grown in the adjoining counties. 



Any fertile, well-drained soil that will produce a good grain, corn, 

 potato or clover crop, will, when properly handled, produce a good 

 sugar beet crop. Clay loams, loams and fertile sandy loams are the 

 soils best suited to the production of beets. Light sandy and marshy 

 soils should not be selected.
