GARDEN GUIDE 



ASTER 



B 1 i s t er 

 Beetles: 



Three or 

 four species 

 feed upon 

 the flowers, 

 the black 

 one being 

 perhaps the 

 commonest. 

 There is no 

 good remedy 

 other than 

 hand pick- 

 i n g and 

 covering the 



Bean Weevil 



Aster Blister Beetle 



plants with mosquito netting. 



BARLEY 

 Army Worm : See Grass. 



BEAN 



Weevil : Adults lay eggs 

 in the pods in the field and 

 keep on breeding in . the 

 dried seed, finally ruining it 

 for planting or for food. 

 Fumigating for 36 hours 

 with carbon disulphide, 

 using about two fluid ounces 

 in a shallow dish on top of 

 the seed in a tightly-covered 

 barrel will kill the weevils 

 without injuring the beana 

 for food or for planting. 

 Mixing the beans with an equal weight of 

 air-slaked lime will prevent damage. If to 

 be used for food only, the beans may be 

 heated in the oven to kill weevils, but if 

 the temperature approaches 150** F. the 

 vitality of the seeds is endangered. 



Green Clover Worm: Occasionally 

 slender, green, wriggling caterpillars riddle 

 the leaves in July. Dust string beans with 

 a fine powder. Beans to be shelled may be 

 sprayed with lead arsenate. 



Aphids : Black aphids on leaves and new 

 shoots sucking the sap. Spray with nicotine 

 solution. 



BEET- 

 SWISS CHARD 

 Leaf- Miner : 



A small fly lays 

 eggs in the leaves 

 and the maggots 

 tunnel or mine

 and lower leaf- 

 surfaces. Destroy 

 all infested leaves 

 and practice late 

 fall plowing. De- 

 stroy all plants 

 of the weed 

 known as "lambs' 

 quarters"in which 

 this insect breeds.

 ish larvae feed on both sides of the leaves in 

 late Summer, often stripping the trees. 

 Spray in July with lead arsenate. 



Bronze Birch Borer: The grub makes 

 a spiral tunnel just under the bark of upper 

 main branches, ridges showing on the out- 

 side. Often kills trees. Cut and burn 

 infested trees before May ist.
