Balm of Gilead. LEAF- RUST. See under Poplar. 



Bean. ANTHRACNOSE, or POD-RUST (Glasosporium Linde- 

 niuthiaimm, Sacc. and Magn.). Reddish-brown scab-like 

 spots appearing upon bean pods, particularity upon the 

 yellow-podded string beans. It also attacks water- 

 melons. 



Preventive. Plant in dry and airy places, on light soil. 

 Remedy. Sulphur and water. 



Bean, Lima. BLIGHT (Phytophthora Phaseoli, Thaxter). 

 Attacks the pods in August and September, covering them 

 with a white, felted coating. It also attacks the young 

 shoots and leaves. 



Remedy. Remedies are not yet known, but the Bordeaux 

 mixture should be tried. 



Beet. RUST {Uromyces beta, Pers.). Powdery reddish- 

 brown spots on the leaves of beets in California, often 

 doing much injury. 



Remedy. Burn the infested leaves. 



Blackberry. CANE- RUST. See under Raspberry. 

 RED OR ORANGE RUST. See under Raspberry. 



Buttonwood. LEAF-SCORCHING. See under Plane-tree. 



Cabbage. CLUB -ROOT or CLUB-FOOT (Plasmidiophora 

 brassicte % Woronin). A cortorted swelling of the root of 

 the cabbage in the field, preventing the plant from heading 

 and causing it to assume a sickly appearance. 



Remedies. Burn the roots as soon as the disease ap- 

 pears. Alternate crops. It is thought that stable ma- 

 nures aggravate the disease. 



Carnation. RUST (Septora Dianthi, Desm.). Attacks the 

 leaves in large, light brown spots, or occasionally the 

 whole leaf becomes discolored and wilts. Probably in- 

 troduced from Europe. 



Preventives. If the disease is feared, be careful not to 

 apply water to the leaves. Eau celeste sprayed upon the 

 plants will no doubt be beneficial as a preventive. Burn 

 all infested leaves.
