fall; if there should be some disease in 

 the fall crop, select seed only from 

 healthy pods, and follow the recommend- 

 ations as given above for cultivation and 

 picking. 



The beans when picked are sorted and 

 packed in hampers holding about seven- 

 eighths of a bushel and are then loaded 

 into refrigerator cars. The cost of ship- 

 ping a car to Northern markets is about 

 $125. and the cost in these car lot ship- 

 ments is about 30 cents per hamper. 



A good yield of beans is 150 hampers 

 per acre, and prices are sometimes as 

 high as $3.00 and more per hamper, for 

 very early shipments. Many growers fig- 

 ure that the crop of beans pays all the 

 fertilizer and necessary expenses for the 

 culture of the succeeding crop, and thus 

 the price received for the latter crop is 

 clear profit. 



BEAX DISEASES 



Authracnose — Spot 



CoUetotricTium sp. 



Causes large, scabby, dead spots upon 

 the pods. 



May be controlled by selecting clean 

 seed and spraying the plants with Bor- 

 deaux mixture. 



Bacterial Spot — Blight 



Bacterium phaseoli Erw. Sm. 



Leaves, pods and stems show watery 

 spots. Not so prevalent on new land. 



Powdery Mildew 



Erysiphe polygoni 

 Produces a white growth of the fungus 

 covering the surface of the leaves in 

 moist weather. 



Sprinkle with dry sulphur.

 Bust 

 Uromyces appendiculattis 



Causes a yellowing and death of the 

 leaves with the production of a dusty red 

 rust on the under side. Not usually de- 

 structive except on plants growing poorly.

BEAX PESTS 



Bean Aphis. See Aphids. 



Besin Cutwonii 



Ogdoconta cinereola Gwen. 



The caterpillar of this species does in- 

 jury to the foliage and pods of beans, at 

 times stripping them. The larvae is a 

 looper, pale green with three white strips 

 and measures, when full grown, about an 

 inch. 



It is distributed pretty well over the 

 country east of the Rockies, but has been

destructive so far only in Florida and 

 Mississippi. 



Arsenical sprays will control it though 

 care should be taken to thoroughly clean 

 the pods if they are to be eaten. 



Bean Weevil 



Acanthoscelides obtectus Say 



Family Bruchidae. 



Bruchiis ohtectus Say 



General Appearance 



The adult weevils are very short and 

 robust, measuring about one-eighth of an 

 inch in length. The odd shape is due 

 to the wing covers being shorter than 

 the abdomen, and the head being carried 

 at right angles to the body. The color 

 varies from gray to brown with a vel- 

 vety greenish tinge. The eggs are white 

 and less than a millimeter long. The 

 grubs are very small, a number of them 

 being able to occupy a single small white 

 bean. They are light cream colored and
