230 Peas and Beans 



(the wire is better) answers for both rows; if the dwarf 

 kinds are grown, one row will help to support the other. 

 Between each two pairs of rows a space should be left wide 

 enough for convenient tillage. The plants should stand 3 to 4 

 inches in the row. One pint of seed of the small-seeded 

 varieties will sow 100 to 125 ft. of single drill. In drills, 1 to 2 

 bushels will sow an acre; broadcast, 2 to 3 bushels. Early 

 peas are usually planted deep, 3 in. and more. Table peas 

 may be had in about 70 days from the sowing of first-early 

 varieties. Green peas in the pod yield about 100 to 150 bu. 

 to the acre. 



Blight (Ascochyta pisi and Septoria pisi).- — These are two 

 distinct blights, yet the symptoms and control measures are 

 in general the same. Circular gray to dark brown spots occur 

 on the leaves and sunken spots of a similar nature on the 

 pods. Sometimes the small black fruiting bodies of the fungus 

 are evident in the affected areas. Control: Seed from disease- 

 free plants is necessary since the fungus may he carried in 

 the seed, and crop rotation should be practiced. Diseased pea 

 refuse in manure carries the organisms, but after fermenta- 

 tion in a silo it may be safely used. 



RooT-ROT (Fusarium sp. and PytMum, sp.). — A dry rot at 

 and beneath the surface of the ground is caused by either of 

 these organisms. Control: Crop rotation, care in the use of 

 infested manure, and the development of resistant strains 

 seems to afford the only possible control. 



Pea weevil (Bruchus pisorum). — A small brownish beetle, 

 mottled with gray, white, and dark brown, that deposits its 

 eggs on pea pods in the field. On hatching, the grub burrows 

 through the pod and enters a seed where it reaches maturity 

 in about 40 days. It then cuts a smooth round hole to the 

 surface of the pea, leaving only the outer hull intact. In the 

 South many of the beetles emerge in the fall and hibernate, 

 but in the North they do not usually emerge till spring. Only 

 one weevil is found in each pea. There is but one brood 

 annually. Peas are not reinfested in storage as is the case 

 with beans. Control: Do not use infested seed for planting
