NEW AZALEAS SHOWN AT 

 GHENT. 



Mr. Winfried Roelker, who has just 

 returned from Europe on the S. S. 

 Vaderland, says that the Ghent show 

 was a pronounced success, especially 

 in the azaleas and rhododendrons. 

 For his group exhibits in eighteen sec- 

 tions, August Haerens of Somergem, 

 Belgium, obtained nine first prizes, 

 seven second prizes and one third 

 prize. The following names and de- 

 scriptions of his group of twelve 

 azalea novelties will interest our read- 

 ers who grow azaleas. 



Winfried Haerens; an early bright 

 Christmas-red flower; a seedling of 

 Ernst Eckhoute x Prof. Welters. 



Brillianta Belgica; a very early 

 bright scarlet; a seedling of Prof. 

 Welters X Simon Mardner. 



Lady Roosevelt; salmon pink; 

 sport ef Rudolf Seidel, which sported 

 from Madam Jos. Vervaene, a sport 

 of Perle de Ledeberg. 



Miss Elsie Roelker; blush rose, 

 flowering camellia-like and erect; 

 sport of Lady Roosevelt. 



Tricorolle; an early crimson red, 

 with three rows of petals; a seedling 

 ef Simon Mardner x Hexe. 



Easter Greeting; a bright crimson 

 color, and good keeper; a seedling of 

 Camille Vervaene x Hexe. 



Christmas Star; a deep bleed-red 

 seedling of Postmaster Stephan by 

 seme other seedling; better color than 

 that of the parent. 



Star of Belgium (Etoile de Belgi- 

 que) ; a seedling of unnamed novel- 

 ties; the color deeper than Postmaster 

 Stephan, the petals pointed, cactus 

 dahlia-like, eight to nine petals to the 

 row in place of five; a very double 



llower. Will not be ready for the 

 trade until 1915. 



Regina Graciosa; very large double 

 white flower; a seedling of Mme.. Her- 

 mann Seidel (white Kerkheve) with a 

 seedling of Louis Cavelier. Will not 

 be ready for the trade until 1913. 



President Alexis Cailler; glossy 

 crimson pink; a seedling of E. Eck- 

 houte X Haerensiana; larger in the 

 flower than Eckhoute. Will be ready 

 this fall. 



Susanna; a very early double white; 

 a seedling ef Mme. Petrick x Anne 

 Hunkel. Will not be ready for the 

 trade until fall. 



Angelinde; a large double white 

 flower of fine shape; is a sister plant 

 te the former, having the same 

 parents; very double but not so early 

 as Susanna. Beth are good keepers. 

 Will not be ready for the trade until 

 1915. 



Mr. Roelker says that Lady Roose- 

 velt and Miss Elsie Roelker were also 

 exhibited by the Kuyk firm but under 

 the names of Daybreak and Blushing 

 Bride respectively and that Haerens 

 is now contesting Kuyk's right to so 

 change the names, before the Cham- 

 bre Syndicale Horticole. 



CONTROL OF TWO ELM-TREE 

 PESTS. 



(From Bulletin 333, N. Y. State College of 

 Agriculture.) 



The elms of the eastern United 

 States are subject to the attacks ef 

 twe serious insect pests, the Imported 

 elm leaf-beetle and the elm leaf-miner. 

 The leaf-beetle attacks both the Amer- 

 ican and European elms. Many Inqui- 

 ries are received each season regard- 



ing these pests and methods of fight- 

 ing them. 



In this bulletin are given the results 

 ef twe years of work in spraying for 

 the leaf-beetle and the leaf-miner. The 

 types ef machines used in spraying 

 large trees are discussed in seme de- 

 tail. Considerable definite data are 

 given also on the cost of spraying 

 large trees. Observations en the life 

 history of the beetle are also included. 



It was found that the imported elm- 

 leaf-beetle ceuld be kept under control 

 very satisfactorily by spraying the 

 trees with arsenate of lead at the rate 

 of four or five pounds to fifty gallons 

 of water. Perhaps twe sprayings are 

 best during the first year, but one 

 thorough application each season 

 thereafter seems to be sufl[lcient. 

 Large elm trees can be sprayed at a 

 cost of thirty to forty cents per tree 

 for one application. 



The elm leaf-miner attacks the Eu- 

 ropean elms by mining out the inner 

 tissues ef the leaves. This insect ap- 

 parently becomes more injurious and 

 widespread each year. 



It was discovered that an applica- 

 tion ef "Black-leaf 40" and soap to 

 the leaves would kill a large majority 

 of the miners if made while the larvae 

 were young. Spraying experiments ex- 

 tending over two seasons show that 

 the "Black-leaf 40" should be used at 

 the rate of one pint to one hundred 

 gallons of water, to which has been 

 added five pounds of ordinary laundry 

 soap or whale-oil soap. The trees 

 should be sprayed just as seen as the 

 mines begin to show and while the 

 larvae are young. 



Notes on the life history of the 

 miner are given in the bulletin.
