Chrysanthemum Disease. By G. Derbonn and G. Mingaud (Le 

 Jardin, vol. xxi. No. 477, p. 12; January 5, 1901).—Phytoecia pustulate, 

 a minute black coleopterous insect ; deposits its eggs in the terminal buds 

 of chrysanthemums from April-July. When hatched the larvae burrow 

 into the shoots of the plant, and even reach the roots. Hardy, outdoor 

 varieties only are attacked, and these should be protected, looked over, 

 watered, &c- f as carefully as the choicer varieties. From April to June 

 the grub may be picked off by hand, and all shoots already pierced should 

 be cut off 2 inches and more below the injury and burned. Sulphur 

 dressings are advantageous in May and June. — F. A. W,

Cocoa-nut Palm, Bud-rot, Disease of (Jour. Imp. Dep. Agr, W.I. 

 vol. vi. No. 3; 1905).— The bud-rot disease has been known in some 

 localities by the name of " Fever." As the result of recent investigations 

 its origin has been traced to the fungus Pestalozzia palmarum (Cooke), 

 but the foul smell of the diseased parts seems to indicate also some 

 bacteriological influence, when the palm is already weakened by fungus. 

 The consensus of opinion appears to be, that when the trees are attacked 

 it is hopeless to dream of their recovery, and the only course to be 

 adopted is to fell diseased trees and burn or properly disinfect with 

 sulphate of copper the terminal bud. Only the mcst energetic action is 

 likely to avail.— M. C. C.
