Elementary Principles of Agriculture 



in the South. They are highly esteemed for their acid 

 berries, which are gathered green and used for making 

 jellies or canned and used for pies and sauces as wanted. 



Gooseberries are very 

 fruitful in the more 

 northern states and 

 Canada. 



532. Grapes are 

 usually trellised, as in- 

 dicated in f 189. 

 With the exception of 

 the European grapes 

 so generally grown in 

 California, the varie- 

 ties of grapes largely 

 cultivated in America 

 have been produced 

 from the several 

 native species, mostly 

 during the last half 

 century. The Euro- 

 pean varieties are not 

 resistant to the 

 phyloxera, a small in- 

 sect that attacks the 

 roots. 



533. Grapes are easy to grow and succeed in most 

 any climate, provided the proper attention be given to 

 spraying to prevent damage from the several species 

 of fungi, such as black rot (Fig. 92), downy mildew 

 (Fig. 90), powdery mildew and anthracnose. The 

 preventative is to spray with Bordeaux mixture, 5-5-50, 

 at frequent intervals until near the ripening period.

 of fruit but they must be sprayed to prevent 

 black rot and other fungi. Top, from un- 

 sp rayed vines; bottom, from sprayed vines.
