Evideuce of tlio spioad of ni(»saic by cultural iJiadiccs in >,'reeiiliouses 

 was afforded in a canning crop near Hammond, tlio plants for which were 

 grown in a grccidiouse and trimmed back with a shears. One mosaic plant 

 was found among the phints in tlie grecidiousi' and in the Held crop grown 

 from these plants mosaic was epideudc. In a greenhouse crop at Lafayette 

 the spread of mosaic was very evidently associated with the use of the prun- 

 ing knife. 



Early bligld caused l>y Allrninrid .sohnii was ratlier considciious in one 

 greenhouse near Indianapolis, causing large target-board lesion'^ on the 

 leaves. The <lisease occurred in the Paoli region btit was not very preva- 

 lent in central Indiana. 



Leaf mold {('I(i<l0f<i)()riinii fiilnnii) was severe in many gr',?ouhouses. 



Antlu-acnose causiMl by CitUclnliichini) pli'iiiiniihs (Fig. 11) was espe- 

 cially prevalent this y(>ar late in Septeiulier. In lields at Lafayette, a con- 

 siderable ]iei-<-entage of the ripe tomatoes slioweil ant hracnose lesions. 



r.acteiial spot caused by lUichrium i .rilinsinii (Fig. 12) was rather gen- 

 eral in the canning crop and was noted on seedlings in Georgia being 

 grown for shipment to Indiana growers. It was also noted in plant beds 

 in Indiana by H. D. Brown. Its attack on the foliuKe of plants in the 

 field is not noticeably destructive but serves as a source of fruit infection 

 which probably takes place through wounds made by inserts. The Ijlack, 

 scabby fruit lesions are very objectionable from the caiaier s point of view. 

 The disease is carried over winter with the seed and seed disinfection in 

 corrosive sublimate 1 to .'J.OOO for "> minutes has be.in recommended as a 

 control measure.
