latluM- liglit soil ami uiir wliich drains 

 readily. 'i'ho failure to obtain iiil't'c- 

 tions is attrilniteil hnj^^ely to the fact 

 that the soil can not lie Ue]>t wet 

 I'lionjili. 



Crown Rot. 



Only hrief mention will lie made of 

 i-rown rot ami th(» othei- diseases to We 

 discussed. 'Vho crown lot. as the name 

 siy;nities, is a lottini^ of the cniwn ot' 

 jdaiits, with the subseiniciit death ol' 

 many of the runners. The same disease 

 occurs ill the cuttiiif^ lieds and is <-(pm 

 monly i<no\vn as damping; olf. In Imtli 

 cases tlie tissues hecoine slimy and rot 

 ra|iidly. Tin* disease occurs in areas 

 where jdants liave lieen too wet. often 

 under a leaic in a water |ii|ie oi- under a 

 hole in tlm roof durinL; |irn|iinnt'd wet 

 weather. 



The disease is apparently caused l.y 

 a fungus, altliough no one seems to 

 have studied it extensi vcdy. Th<> or- 

 ganism in its ve^^etative and S(derotial 

 stajies has the ajipearance of a sidcni 

 tinia. I'ossildy it is S. liiiert iana. a 

 i-ommoii disea-^e pinducer. 



Sanitation Saves Stock. 



The s|ie<Mes of siderotinia are. for the 

 mo-.t part, ones that take advantage of 

 plants that are in a weakened cMjndition. 

 They more often exi-t as saprophytes 

 and are not jiart iiularly choice ahout 

 the source of foo.l. i"or that n^a^on it 

 is douldfnl whether sanitary measure^ 

 i-ecommeiided ill the casi' of tlie thiida- 

 \ ia root rot would ]iro\c i^ntirely ef- 

 fective. Here IS a <'ase wlii'lf the y^ood 

 health !<{' the host plant is of impor 

 tam-e in disease control, wiiereas, witli 

 the more active ]iarasites. constitution- 

 ally sickly plants are fre<piently uii 

 attacdu'd. Since the watersoakiii;; of 

 soil leads to an unhealthy condition 

 ami seems to be the most frecpieiit at- 

 tcTidant circiimstani'e of this troulile. 

 the Bkatter of control is ndativtdy siin- 

 jile. Aside from the removal »\' dis 

 eased ]>lants, some growers seem to have 

 cluM'ked the spread of the disease by 

 heavy dusting of air-slaked lime in the 

 aO'ected region. 



Leaf-Spot and Gray Mold. 



As the name ini|dies. leaf spot dis 

 eases are characterizecl by ceitaiii d(di 

 nite spots on the foliage. 'I'liere are a 

 number of diireroiit organisms concerned, 

 ea(di one of which forms a perfectly dis 

 tinct ami definite type of lesion. The 

 iiMoe important (Uies. liowe\ er, are Alter 

 iiaiia \ i(da' and I'liyllost ict a \ i(d;e. l)oi- 

 sett and (ialloway regard the disease 

 caused by alteiiiaria as the most serious 

 \ i(d(d disease, but leaf-s]iots of any kind 

 ha\e ii(d be( n particularly destructive in 

 our houses in recent years except in a 

 t'ew ilist aiK'C-. Ill one hoii-e, liowe\ii'. the 

 alternaria disease \\;is (Ic-t nict i\ e I'oi

spraying of \ icdets t'or f(diage tron 

 bl.'s has met with i ndilfeiciit smce^-. 

 according to cxiieii meiits ot' llaNtecl 

 and (ialloway. If tin- jdants are wa- 

 tered late in the day. the (dinging drojis 

 of watei should lie knotd<ed lidiii the

stick held at a le\el whiidl will c.-ni-e 



the leaves to ln-iid and then sjiring iiack

IIIL; and tlie jHdlllJit lemo\al of -^liotted 

 leaves are the JHeca lit ions to be oii 

 ~el\ed ill combating these diseases. 



l,ea\es and stems often turn ycdiow 

 or iiidwn and in a day or two liecome 

 covereil with a gray mold. This mobl is 

 a t'lingus of the geiiiis botr\tis, jio^sjJdy 

 I'.otrytis vulgaris, a I'ommon organism 

 living iiMistly as a sajirojihyte and only 

 nciiining on living jilants that are low 

 in vitality. Whenever a le.af or stem 

 is liroken or is ginlb'd by Ihiidav ia, 

 botrytis is ajd to ajijiear on it to com- 

 jdete the destruction. Th(> occurrence 

 of the mold in the house is not of 

 its(df to bo regarded seriously.
