Fundus Diseases of Cacao, 



^^^^ l^Jji' II 1'^ liiiigns ilisoMSL-s of i.viL'fio liiivc recciv<-(l 

 ^^1 «);'-, ronsidcrable attention of hite years in the 

 v^ jCaJ' '^ West IimIics. W hen it, i,s renionibefed that 

 c.-xeao (■..riM- s^ ooiid in imporlanee to sugar among West 

 Indian jitodin-t^, and t!i--it the exports for 1!J07-S were 

 valued at over £2,000,00(1, the necessity of taking 

 every possible measure to eradicate the various diseases 



that threaten to reduce the value of th" industry is at 

 once apparent. 



At the West Indi.in Agricultural Conference held 

 at Barbados in January last, the whole question of 

 fungus diseases on cacao in the West Indies, etc.,. 

 together with the methods that shoidd be adopted in the 

 management and sanitation of cacao orchard.'^, so as to- 

 prevent the occurrence of diseases, was dealt with in 

 a paper read by Mr. F. A. Stockdale, B.A., F.L.S., 

 Mycologist on the staff of the Imperial Department of 

 Agriodture. This paper has been ptiblisht-d in the- 

 lIVs'^ luilian Bidld'ni (Vol. IX, No,2), and it has also- 

 been issued in booklet I'orm, as No. -T.^ in the Pamphlet 

 Series of the Department (price '\>(l., post free 5(7.). 



Canker and root disease are the most destructive 

 among the jiar.-isitie diseases affecting cacao in the 

 West Indies, and these have lieen carefully investigated. 

 Die-back, brown pod rot, and black pod rot have alsa 

 received considerable attetition, and there are at pres- 

 ent several other diseases under itivestigation. 



( 'aid<er is a branch or stem ilisease, which occnrs- 

 morc frei|uently among old trees than among young 

 ones. It may be caused by several fungi that have 

 been shown to be wound parasites. I'he e.xistence of 

 the disease may be noticed from the change in appear- 

 ance of the bark at affected spots. The best time to 

 look for these areas would appear to be in the dry 

 season, immediately after a shower of rain, for the 

 grevish-browM .-ifleeted areas do n(jt dry as (piickly as- 

 r.he tuiaffecled portions of the bark. When the disease 

 is fnll\ cst.ablished the bark presents a deep claret 

 colouration on being cut, and is moist and soit to the 

 touch. The outermost layers of wood arc also affected. 

 Canker spreads rapidly through the bark of a tree.
