Experiments on Red Ring Disease of the Coconut in Grenada. — Agric. 

 News, Barbados, xxi, no. 519, 18th March 1922, p. 94. 



Experiments with salt as a preventive of red ring disease of coconuts 

 [R.A .E., A, X, 107] have been continued. Salt tied up in gunny sacking 

 was fixed to the highest part of the crown of various trees, so that the 

 drip could soak down to the bases of the expanding and expanded 

 leaves. The trees were then inoculated in July with fragments of 

 infested material. When examined before the end of November, all 

 showed evidence of Nematode infestation, showing that the treatment 

 had been ineffective in preventing or even appreciably delaying infec- 

 tion. Another set of eight trees was treated by the soil only being 

 inoculated with salt, but this also failed to afford protection. Eight 

 trees banded with a mixture of two parts tar to one part tallow at
