TREATMENT FOR ANTHRACNOSE. 
By E. H. RAINFORD, 
Viticulturist, Queensland Agricultural Department. 
In different parts of the colony a considerable number of vines shows attacks of 
Anthracnose, which vignerons should not neglect, as not only will a consider- 
able amount of fruit be damaged by it, but also the wood for next year’s 
pruning, which may affect next season’s vegetation and crop. The best system 
to adopt with Anthracnose, or Black Spot, is the preventive treatment by 
sulphuric acid solution, as already explained in the Agricultural Journal for 
August, 1898 ; but, notwithstanding this precaution, the disease will in certain 
seasons make its subsequent appearance, and summer treatment be required. 
For those who require to get rid of this pest the following simple and 
economical receipts are given :—

Finely divided slaked lime AA one As cat BD

Hither of the above mixtures should be dusted over the shoots and 
bunches early in the morning, before the dew evaporates, twice or thrice, at 
intervals of ten days. It would be well to try both the above combinations in 
different parts of the vineyard to see which gives the best result. A word 
of warning—be very careful that the lime is thoroughly slaked, otherwise it 
may cause burning and scabbing of the leaves and fruit. After slaking, the 
lime should be left exposed to the air a few days, occasionally turning it,

THBHOBROMA CACAO. 
By E. COWLEY, 
Manager, Kamerunga State Nursery, Cairns. 
Nora great deal is known about cocoa in Queensland, for little has been 
grown in the colony. That it can be grown was evinced at the last Cairns 
Show, when some pods of the fruit were displayed, the same being grown at 
the State Nursery, Kamerunga. What, indeed, could not Queensland grow ? 
Perhaps the mangosteen and the durian* would puzzle them, but cocoa has 
been exhibited before now in a Cairns Show. A few years ago the Messrs. 
Swallow Bros., of Hambledon, showed a pod which puzzled many persons. 
However, the Messrs. De Moleyn are planting a considerable area in the 
Russell district, where probably the plant has the chance of thriving better 
* Three varieties of mangosteen have been discovered in Queensland—the latest from Cairns. 
The durian will also flourish where the Jack fruit thrives as it does in Queensland.—Ed. Q..A.J.
