;< "^TJ SQUIRT BERRY ( Phoma tuberculata, McAlp.). This disease is 

 at times troublesome, especially amongst the Muscats. The fruit is 

 the part attacked ; it is at first ashy grey or slaty blue in Jcolour, 

 dotted and speckled with numerous small pustules, for a long time 

 covered by the outer skin or epidermis. When gently pressed 

 between the finger and thumb the berry squirts out its contents. 

 Towards the end of the season the berries dry partially, but are 

 always pliable. 



No experiments relating to preventive means have been tried. 

 I have noticed, however, that vines trained alongside a fowl yard 

 were much more severly attacked than others growing a short 

 distance away. Manuring with potassic and phosphatic fertilisers 

 as well as liming seems to lend to the vines greater power of 

 resistance.
