THE CUBA REVIEW 



ologists as "heart rot" and "bud rot." The 

 C'JBA Review has printed special articles 

 on this disease, giving the opinions of 

 Mr. \V. P. Mornc, formerly connected with 

 the Cuban Agritcultural Experiment Sta- 

 tion, and John R. Johnston of the United 

 States Deiiartmcnt of Agriculture. Mr. 

 Home's remedy was the same as that now 

 determined upon by the government, to 

 burn affected trees and thus stamp out the 

 disease. 



Pineapple Diseases 



In the Philippines they have trouble with 

 insects attacking pineapples. For ants and 

 mealy bugs it is advised that when applying 

 fertilizer, it should be mixed with about 

 one-fourth of its bulk of tobacco dust, and 

 even if the dust alone is thrown in the 

 crown, it will prevent the appearance of 

 the pests and often cure incipient attacks. 

 The tobacco dust also acts as a stimulant 

 to the plant. 



Wilt is another disease, easily recognized, 

 as the leaves change color, and the whole 

 root system becomes diseased. Australian 

 investigators claim it occurs where a field 

 has been cropped too long or plants from 

 the same supply used. Plants grown under 

 different conditions should replace the old 

 ones every few years. The remedies are : to 

 never plant a diseased slip, and to pull 

 out all affected plants, burn them or cover 

 with quicklime, also cover the soil with 

 lime and leave it exposed to the sun, stir- 

 ins.; it from time to time. 



Spike or long leaf. — In the final stages 

 the central leaves do not unfold, hence the 

 name. 



Improper and poorly proportioned fer- 

 tilizing is the cause. Slips should never be 

 planted, as 70 to SO per cent fail to pro- 

 duce marketable fruit. The remedy is to 

 use tankage, dried blood or bone meal, in- 

 stead of nitrogen and phosphorus fertilizers, 

 avoiding acid phosphate, unless necessary. 



Cahe/onas and Red Spanish are the fa- 

 vorite pineapples with growers in Porto 

 Rico, says U. S. Special Agent John M. 

 Turner. The former is a very large fruit 

 which sells for fifty cents in the U. S. 

 markets, but though they require to be care- 

 fully handled to prevent bruising, the net 

 prolits, says the agent, are $1,G00 per acre. 



The area at present under cultivation is 

 now 2,000 acres. 



Supply Pasture and Grain 



A combination of pasture and grain pro- 

 duced pork at a cost of $3.50 per 100 

 pounds. We do not know how it would 

 be possible to pay a more fitting compli- 

 ment to the pasture as a cheap food prod- 

 uct than to merely give these figures. 



The man who tries to raise hogs without 

 furnishing them with a good pasture is 

 tremendously handicapped as against the 

 individual who uses a bit of forage crops.
