ROSE PESTS. 



BY W. HUNT, SUPT. GREENHOUSES, O. A. C, GUELPH. 



:ITH the advent of June blossoms, 

 and the increasing- heat of the 

 sun, insect pests are sure to 

 make their appearance. The 

 old adage "that an ounce of prevention is 

 better than a pound of cure " is one that 

 flower lovers will do well to bear in mind, 

 and apply practically its teaching at this 

 season of the year. 



Much of the success to be attained during 

 the summer season both in the flower and 

 fruit garden, depends very largely on prompt 

 and vigorous action in preventing the devel- 

 opment and increase of the many kinds of 

 insect pests that prove so troublesome and 

 destructive in our gardens. Too often the 

 application of remedies and preventive meas- 

 ures for the extermination of insect pests, 

 etc., is left until the plants have become so 

 badly infested that they are hopelessly 

 spoiled for floral or decorative purposes for 

 the greater part of the season. 



How often do we see rose bushes with the 

 foliage and buds partly eaten and destroyed 

 by the rose-worm or slug, long before the 

 buds have had time to develop even the 

 faintest tinge of the gorgeous colors of 



their beautiful petals, when an early and 

 timely application of a little dry hellebore 

 powder, sprinkled over the bushes before the 

 flower buds developed, would have prevented 

 the disfiguration of the plants as well as the 

 loss of the roses. I have found it a wise 

 course to always give rose bushes a sprinkle 

 of hellebore powder as soon as the foliage 

 has partially developed, before the flower 

 buds are showing very prominently. By 

 doing this and repeatifig the operation 

 about once a week, until the flower buds 

 commence to open out into flower, the foli- 

 age as well as the flower buds can be saved 

 from disfiguration and partial ruin. The 

 best time to apply the hellebore is early in 

 the morning, whilst the foliage is damp with 

 dew. 



Take again the rose-thrip, that is so 

 troublesome to rose-growers from the time 

 the rose buds appear until early autumn. 

 This insidious little white fly or midge, that 

 secretes itself on the under side of the 

 leaves, is oftentimes not detected until the 

 foliage has become bleached and whitened 

 by its destructive attacks. Its presence, 

 however, can usually be detected if a close
