THRIPS. 



With the season of steady firing ap- 

 proaching, when we should be cutting our 

 best crops, there is always the danger of 

 thrips lurking in the houses, ready to 

 pounce on our best specimens. Espe- 

 cially is this the case in Beauty houses. 



To get rid of this pest before it be- 

 comes too numerous, and before our 

 crops are so far developed that the in- 

 sect can find a lodgment among the pet- 

 als, measures strong and drastic should 

 be adopted now. This pest is very often 

 introduced into the house with the first 

 mulching material used, either in the 

 form of eggs or in the larval stage, and 

 under the genial conditions of the rose 

 house thrives and multiplies rapidly. 



As a preventive to this introduction 

 of thrips the manure pile should be kept 

 free of weeds and turned over frequently 

 during the summer, as these weedy spots 

 are the places where they congregate. 

 It is also advisable to keep down weeds 

 in the vicinity of the houses and, if pos- 

 sible, to bum the herbage during a dry 

 spell. 



To clean them out of the houses after 

 they have a foothold requires a great 

 deal of work, patience and persever- 

 ance, as the broods come rapidly and, 

 although the adult insect succumbs 

 readily to tobacco fumes, they are so 

 active that it is^ ^ard to get the fumes 

 to touch theni)' as they run to cover on 

 the first intimation of danger. 



The larvae, making their home among 

 the mulch and loose soil on the surface 

 of the bench, are still harder to reach 

 and it is only by persistently keeping 

 after them and catching each brood at 

 the stage where it is easiest destroyed 

 that we can get the best of them. 



It is much easier and eafer to use 

 the measures necessary to effect this pur- 

 pose before the plants begin to produce 

 their crops than afterwards, as the fre- 

 quent use of fumes is almost certain to 

 bleach the petals and destroy their value. 



The use of cayenne or red pepper, 

 which has frequently been advocated in 

 these columns, if intelligently and per- 

 sistently applied is a sure and safe 

 remedy. This should be applied some- 

 what in the following manner: 



Get some iron plates 8x12 inches in 

 size; heat them till they are red and 

 lay them in the paths at distances of 

 twenty-five feet apart. The operator 

 should then start at the end of the 

 house farthest from the door, covering 

 each plate with the pepper, and get 

 out of the house as quickly as possi- 

 ble, as the fumes are vAry disagreeable 



and even dangerous. In two hours the 

 fumes will have done their work and the 

 ventilators can be raised. 



The usual weekly fumigation should 

 not be allowed to lapse during this 

 course, as we have found from experi- 

 ence that these pepper fumes have little 

 impression on green fly. BiBES. 



ANTHRACNOSE. 



For years I have found Mme. Chate- 

 nay to die out considerably during the 

 months from Pebruary to May. The 

 stock was usually planted in June, in 

 solid beds, and made a fine growth, but 

 in a short time a part of the plant would 



ter, this seems to be a case of rose 

 anthracnose, but without examining a 

 specimen it is impossible to diagnose 

 the case with any certainty and hence 

 it is not safe to recommend a remedy. 

 Lift one of the affected plants, shake 

 off the soil, pack the root in damp moss 

 and forward, and I will give the best 

 advice in my power, whether the trouble 

 be as I suspected, or otherwise. Bibes 



A« B. CARTLEDGE. 



A. B. Cartledge, senior partner of the 

 firm of Pennock Bros., Philadelphia, is 

 one of the most deservedly popular 

 young men in our profession. His in- 

 terest in the pioneer florist of Phila- 

 delphia is inherited from his father, 

 whose memory is kept green in the 

 hearts of all who knew and loved him. 

 Mr. Cartledge 's sunny disposition never 

 fails to win the friendship of his busi- 

 ness associates; he combines in a rare 

 degree what may be termed the vital 

 spark with that quiet decision that 

 overcomes worries, both great and 

 small, and robs "no" of -its sting.
