Symptoms 



Bremia Lactucae. Allow ample space ; remove 

 completely and burn afEected plants and aU old 

 leaves from beds, etc. Sowthistle and some 

 other weeds are also liable to attack by this 

 fungus. 

 Lily. 



Foliage and Stem. — Brown spots on leaves 

 and buds which, with the stem, subsequently 

 die and dry up, while the flowers are distorted. 

 Due to Botrytis cinerea. Lime (mortar rubble 

 or chalk) should be mixed with the soil for 

 those lihes that do not dislike Ume, especially in 

 the upper three or four inches, and the plants 

 grown in airy places not exposed to strong cold 

 draughts or late frosts. Dusting the bulbs with 

 sulphur is reported to have been beneficial. 

 Lyoknis. 



Foliage. — Yellow blotches on foUage bearing 

 groups of chestnut spores often in concentric 

 rings. Rust due to Puccinia lychnidearum. 

 Not usually serious enough to spray for. 



Flower. — Pollen replaced by purplish-violet 

 fungus spores which escape and discolour the 

 middle of the flower. Smut due to Ustilago 

 violacea. Destroy the plant, as the fungus is 

 perennial from the seedling stage. 

 Malva. 



Various species are attacked by Hollyhock 

 rust. See Hollyhock.
