THE RED SPIDER. 97 



preferable to the so-called powdered sulpliiir) is very 

 fatal to the Eed Spider. Soft soap and Gishurst's Com- 

 pound, as used by gardeners, are old and well-tried 

 remedies, and, when the fruit is off' the tree, tobacco 

 water is a very good remedy against this and many 

 other insects. 



In using either the syringe or spraying pump against 

 Ked Spider, it should be remembered that the mites are 

 mostly on the under part of the leaves, so that the various 

 solutions must be sprayed in an upward direction^ and 

 with considerable force, otherwise the treatment will have 

 very little effect on this pest at any rate. When a 

 tree is badly attacked by Red Spider, shake as many 

 leaves as possible off' the tree into a sheet and burn them. 

 Paint the stems with a hard brush, using slaked lime and 

 sulphur mixed for the purpose. In a small garden, the 

 sulphur bellows can be used with good effect. In heated 

 conservatories, the best plan is to strew sulphur upon the 

 pipes ; this, however, must ])e done Math care, or else the 

 tender plants may be irreparably injured, as it is imperative 

 that a proper moisture be maintained during sulphuring 

 time. In the kitchen garden, if l^ieans, &c., are badly 

 affected, destroy them at once, and constant hosing, 

 especially where plants are under glass, is of great benefft 

 as a preventive against the Eed Spider, Thrips, &c. In 

 large orchards the use of sulphur steam may yet prove 

 the best remedy. For Crotons, Cordylines, and many 

 other plants, dipping in a solution of tobacco water is an 

 old and very effective remedy. 



Luckily for growers, this pest is not difficult to destroy, 

 but to do this the treatment should be carried out with 

 both care and promptitude.
