Maladies and Insect Pests. Many insects attack 

 the Vine. Mealy bug is especially troublesome if 

 allowed to gain a foothold. To keep it out, wa.h

 may be removed, but barking, as frequently 



in the house; it attracts wasps. Small birds 

 sometimes like Grapes, but the netting will keep 

 them out. For light attacks of mildew, dust with 

 llowers of sulphur ; for bad attacks, paint the pipes 

 with the sulphur made into a paste with water, 

 get the pipes hot, and shut the house up. The 

 sulphur fumes kill the mildew spores, but the 

 remedy is a drastic one, and only to be used as a 

 last resource. Avoid cold draughts. Cracking is

 spring and summer keep a close watch for bug 

 colonies, and touch them with a soft brush dipped 

 in Lemon Oil. Ited spider sometimes gives trouble 

 towards the end of the season. Dusting with 

 flowers of sulphur will check it. For thrips sponge 

 the affected leaves with tohaero water or Nicotine 

 Soap, or vaporise lightly. Weevils must be searched 

 for by lamplight, caught, and killed. Hats and 

 mice are troublesome to ripe fruit, and must be 

 trapped. If wasps and Hies are numerous, cover 

 the ventilators with line muslin, and. if necessary, 

 the bunches also. Do not set traps of sweet liquid

 Kemedy, avoid heavy waterings to Vines ripening 

 fruit, and allow a moderate extension of the sub- 

 laterals. Shanking, i.e. the shrivelling of the foot- 

 stalks of the berries, is brought about through the 

 roots being in cold subsoils. Kemedy, keep the 

 touts under control. If necessary, lift and replant

 Bleeding is the copious extravasation of sap from 

 wounds. It is caused, if Vines are cut or broken 

 early in the season before they are in full leaf, by 

 the pressure of sap drawn up from the roots.
