No. 4.] CUCUMBER GROWING. 423 



and no record of its appearance later than December is 

 known in this State. We have never known indoor cucum- 

 bers started in October or November to be aftected with 

 this fungus, but those started in August or September are 

 likeh' to he. From this it appears that greenhouse crops 

 started in August or September become affected from out- 

 door crops, as this is the time the mihlcw is prevalent on 

 outdoor cucumbers. This mildew can be completely con- 

 trolled by spraying with Bordeaux mixture every two weeks ; 

 but for indoor cucumbers it would be better to plant them 

 in October or November, rather than earlier, as there is 

 little likelihood of these becoming infected. 



Anthracnose {CoUetotrichum Lagenarium (Pass.) Ell. & 

 Hals. ) . — At the present time this fungus causes more trouble 

 to outdoor cucumbers and melons than all other organisms 

 combined. The attack has been so severe in some instances 

 that it is almost impossible to succeed in raising a crop 

 without having it all destroyed before maturing the fruit. 

 The fk'st indications of anthracnose are ^^ellow spots on the 

 leaves, which multiply and enlarge, and in a very short 

 time the whole plant succumbs. The spread of the disease 

 is frequently so rapid that it only requires a few days for 

 the entire crop to die. Crops killed by this fungus present 

 a dry, parched aspect, as if they had been subjected to hot 

 and dry winds of the greatest intensity. Greenhouse cucum- 

 bers are also aflected with antliracnose in the spring of the 

 year. We have, however, never observ^ed this fungus on 

 indoor crops earlier than March 24. The anthracnose does 

 not appear so destructive in the greenhouses as out of doors ; 

 at least, greenhouse cucumbers will continue to live some 

 time after beino- infected with this fungus. All of the ex- 

 periments made in spraying for the control of the antlii'ac- 

 nose have been very discouraging. Al)Out all that can be 

 said at the present time is that vines thoroughly sprayed 

 every one or two weeks will remain green slightly longer 

 than those not sprayed. During the season of 1901 it 

 caused an immense amount of damage to melons, making its 

 appearance during the latter part of July in this State.
