HC Deb 13 March 1946 vol 420 cc1091-2
41. Mr. Turton

asked the Secretary of State for the Colonies what is the effect of the disease known as '' Sudden death '' on the clove trees in Zanzibar; what percentage of the trees is affected; and what steps are being taken by research, and otherwise, to deal with this disease.

Mr. Creech Jones

The effect of the disease is that of a general wilt. Only a few days elapse from the time that the first obvious symptoms appear until the tree is dead. The estimated average annual loss of trees is about 10,000, representing just under one-fifth of 1 per cent. of the estimated clove trees in Zanzibar. Experiments on manurial and moisture requirements are being conducted by the Department of Agriculture, and in collaboration with scientists in this country the mineral nutrition aspect is being investigated. Experience shows that affected areas can be successfully replanted, and large Government nurseries are maintained from which seedlings are readily available for the regeneration of these areas.

Mr. Turton

Is the hon. Gentleman aware that many people attribute the onset of this disease to the change of Government in this country?

Mr. W. J.Brown

Might I ask whether there is any affinity between the symptoms of this disease as read by the hon. Gentleman and the experience which happened to the Tory Party last July?

Mr. Speaker

I repeat the advice that I have just given about supplementary questions and the evidence of the acting Leader of the Opposition.
