APRICOT BEAN 265 



Control. Rake and burn leaves, or plow under very early 

 (before blossom buds open). Spray with lime-sulfur 32 Beaume, 

 1-40, or bordeaux, 3-3-50: (a) when blossom buds show pink, 

 but before they open ; (6) when the majority of petals have fallen ; 

 (c) three weeks after 6 depending upon the weather ; (d) if a late

 YELLOWS. See under PEACH, p. 276. 

 BLACK-SPOT or SCAB. See under PEACH. 



Asparagus. RUST. (Puccinia asparagi). A rust of the tops, which 

 is often so severe as to kill them, thus interfering with root de- 

 velopment. 



Control. Three weeks after cutting stops dust the young tops 

 with dry sulfur at the rate of ll sacks of sulfur per acre. This 

 should be done very early in the morning while the dew is 

 still on, and only on a dewy morning. In a month or less make 

 another application, using 2 sacks of sulfur per acre. The 

 sulfur must go on in a dusty, smoky cloud and form a covering 

 over all the growth. Flowers of sulfur is more satisfactory for 

 this work, and is less expensive in the long run. Dusting machines 

 may be obtained on the market. 



Barley. SMUT. See under SMUT OF CEREALS, p. 260. 



Bean. ANTHRACNOSE or POD-SPOT (Colletotrichum lindemuthianum). 

 Reddish-brown scab-like spots appearing on stems, pods, and veins 

 of leaves, particularly on yellow-podded snap beans. The fungus 

 grows through the pod and into the young bean seed. It lies dor- 

 mant in the seed, and becomes active when the bean is planted. 

 Control. Select pods which are free from the spots and save 

 the seed for planting. Such seed will grow a clean crop. If dis- 

 ease appears in the garden, it can be controlled by thoroughly 

 hand spraying the vines from beneath as well as above, repeating 

 the operation every ten days as long as necessary. 

 BLIGHT (Bacterium phaseoli). A bacterial disease. Causes large, 

 papery spots on leaves and watery spots on pods. 

 Control. As for ANTHRACNOSE. 



Bean, Lima. BLIGHT (Phytophthora phaseoli). Attacks the pods 

 in August and September, covering them with a white, felted coat- 

 ing. It also attacks shoots and leaves.
