THE GRAPE 



INSECT ENEMIES OF THE FOLIAGE 



The Grape-vine Flea-beetle is a small, steel- 

 blue beetle that is often very destructive to grape-vines. 

 As soon in spring as the buds swell the beetles attack 

 them, and continue feeding for three or four weeks, 

 during the latter part of the time depositing small, 

 orange-yellow eggs in clusters on the under sides of 

 the leaves. The eggs hatch into small, dark-colored 

 larvae that gnaw irregular holes in the leaves. When 

 fully grown (three or. four weeks after hatching), they 

 are about three-tenths of an inch long, brown in color, 

 with six legs, and four or five black dots on the back 

 of each ring or segment of the body. The head is 

 black, and there are numerous hairs on the body. 

 They now enter the soil, pupate, and a few weeks 

 later emerge as beetles, which feed upon the foliage 

 and lay eggs for a second brood of larvae. 



Remedy — Spray with arsenites as soon as beetles 

 appear in spring; or else with the arsenited Bordeaux 

 mixture. Repeat in ten to fourteen days if necessary. 



FUNGUS ENEMIES 



The Black Rot of grapes has long been recog- 

 nized as the most destructive fungous disease which 

 American vineyardists have encountered. Generalh 

 the fungus first appears in the shape of roimd, reddish- 

 brown spots on the grape leaves. About a fortnight 

 later the attack on the berries will be noticed. The 

 efifect on these is most disastrous ; as the mycelium 

 develops among the cells of the fruit the berries stop
