lem is to concentrate the vitality of the vine into fruit. Cul- 

 tivation modifies the Jiabit of the vine, 



A natural division of species is the ^'Raisin Grape" of 

 the sub-tropical while the "Non -Raisin"'"' is of the temperate 

 zone. Our best table grapes come to x>erfection at the north- 

 ern margin of grape cultivation. Here they reach perfec- 

 tion of quality and quantity. Ever remember that quality 

 determines the commercial value of any fruit. 



DISEASES AND INSECTS 

 Anthracnose, a fungus disease which makes deep holes 

 and scars on young canes and ruins the foliage. Remedy: 

 Spray with four pounds copper sulphate to 50 gallons of 

 water BEFORE buds open. Follow later with bordeaux. 

 In fact we know of no more potent factor to control all se- 

 rious grape fungus diseases than bordeaux, using from three 

 to six sprayings. We believe that this mixture is better 

 adapted to the grape than any other fruit. 



Black Rot, a fungus growth. Spray bordeaux, first af- 

 ter fruit is set and three to five times later. Bum all prun- 

 ings, diseased fruit and foliage. 



Downy Mildew, brownish white patches on under side 

 of leaves. Use flower of sulfur, follow with bordeaux. Spray 

 when seen. This controls it. Sulfur is most excellent for all 

 forms of mildew, 



INSECTS 

 The "Berry Moth" is the parent of a very small worm 

 that burrows into green grapes spoiling the fruit. Spray 

 with arsenate of lead, but bagging the clusters is best. Burn 

 all dry foliage. 



Cane Borers. Clean away soil near roots of vines and 

 wash with "Borowax" and then bank up soil. Burn any drj^ 

 foliage. Dig out borers first- 

 Rose Beetles. Spray with kerosene emulsion. Use one 

 pound alum to four gallons water. Sweep off dormant beetles 

 and burn in oil. Covor single vines with netting. Set a white 

 flowering shrub near vines.
