Rose Aphis. The aphis which is so troublesome 

 to Roses is A. Rosa;. It is most prevalent in cold, 

 dry weather in spring, especially on Roses exposed 

 to cold draughts. Under glass it may be dealt 

 with generally by fumigation in the ordinary way, 

 and outdoors by syringing with Quassia and soft 

 soap mixture, as directed under APHIDES. The 

 enemy should be attacked as soon as it is observed, 

 as it multiplies with extraordinary rapidity. 



Rose Bedeguar. This is a large gall found on 

 the twigs of the Kose, and formed by the numerous 

 cells in which are found the larva; and eventually 

 the pupae of Rhodites Ro.;e. This is a four-winged 

 fly, generally black, with the exception of the legs 

 of both sexes, and a portion of the abdomen of the 

 female, which are brown. The Bedeguar is gener- 

 ally round, and is covered with moss-like green or 

 red hairs. Removing infected portions and burn- 

 ing them is the best preventive of the spread of 

 the disease. 



Rose Galls. In addition to the Bedeguar, the 

 Rose is subject to several other galls. Those of 

 Rhodites centifolite resemble Sweet Peas, and 

 occur on Rosa Centifolia. On the Dog Rose 

 (canina) and the Sweet Brier similar galls, formed 

 by Rhodites Eglanteri:e, are found. R. Mayii also 

 forms galls on R. canina, and R. Rosarum produces 

 others like Peas, but with spines, on the leaves of 

 several Koses. Then there are irregularly shaped 

 red galls on the leaves and young shoots of R. 

 canina and R. spinosissima, as well as smnll 

 fleshy galls on the leaves of almost all Roses caused 

 by the gnat called Cecidomyia Rosa:. Removing 

 and destroying affected portions ought to be 

 attended to as soon as possible. 



Rose Grub. The principal grub which infests 

 the Kose is the larva of Tortrix bergrnanniana, the 

 Rose Tortrix, a small black moth. The grub 

 itself is too well known to need description, and 

 every Rose grower is unfortunately acquainted with 

 its ravages. Hand-picking remains the best 

 remedy, but various insecticides are often helpful. 

 Anisopia horticola is the Rose Beetle, whose larvae 

 are sometimes called Rose Grubs by gardeners. 



Rose Mildew. The presence of Sphserotheca 

 pannosa, a very injurious Fungus, is soon evident 

 in the deformed and swollen calyces of the flowers 

 and the blistered and distorted leaves. On examin- 

 ation the pale grey mycelium of the Fungus will 

 be readily seen. Some varieties of Roses are more 

 liable to its attacks than others, and it often attacks 

 Roses which are much exposed to cold draughts. 

 Powdered sulphur dusted over the parts affected, 

 a mixture of one part of powdered quicklime to 

 three parts of flowers of sulphur, or a solution of 

 1 oz. of potassium sulphide in 3 gallons of water, 

 are all applied by experienced rosarians. 



Rose Rust. The Rose Rust (Uredo or Lecythea 

 Rosaa) and Rose Brand (Phragmidium mucronatum), 

 at one time considered two species of Fungi, are 

 now believed to be respectively the summer and 

 autumn forms of the same pest, Phragmidium mu- 

 cronatum. In its earlier form this fungus shows 

 itself in the shape of a yellow, dust-like substance 

 on the under surface of the leaves, and is composed 

 of one-celled bodies covered with prickly warts. 

 The later form is formed of a row of cells, each 

 with a dark brown warty coat, which shows liko 

 black clots. The removal of infected leaves, 

 spraying the plants, and then dusting them with 

 powdered sulphur, are generally recommended. 

 Such a preparation as Abol may be used with 

 advantage. 



Rose Sawflies. Among the many enemies of the 

 Rose the sawflies (Tenthredinidaa) are conspicuous 

 from the injury they inflict upon the leaves or 

 twigs and, in some cases, even Tihe pith of the 

 plant. They are very numerous, and cannot be 

 named and described in detail, but their presence 

 will soon become apparent. Hylotoma Rosas is the 

 most destructive. The insects appear in May and
