Symptoms 



Peony. 



Foliage. — Leaves become spotted with brown 

 or turn wholly brown, or base of stalk becomes 

 brown and leaf flags ; spots covered with grey 

 fungus, due to Botrytis Paeoniae. Small black, 

 hard, resting bodies about size of mustard seed 

 form on lower part of stalk or in soil. Remove 

 all diseased fohage ; spray with Bordeaux 

 mixture or soda-Bordeaux (7). 



Palms. 



Foliage. — ^Black spots are frequently de- 

 veloped on fohage of palms of various kinds due 

 to fungi (more than one species being involved). 

 The destruction of deadleaves and the removal of 

 affected parts are the best modes of treatment. 



Pansy. See Viola. 



Parsley (see also Parsnip). 



Foliage. — Small brown spots on foliage on 

 which minute black dots occur, due to Septoria 

 Petroselini, possibly identical with the fungus 

 which attacks celery (q.v.). Not generally 

 troublesome ; but if it should prove so, spray 

 with liver of sulphur (7). 



Parsnip. 



Foliage. — White mouldy patches on under 

 side of leaf, which turns brown in patches. 

 Due to Plasmopara nivea. The fungus also 

 attacks the root and forms rusty patches upon 

 it. If outbreak spreads, spraying with Bordeaux
