 On land which has been heavily infested it is impossible to
 grow profitably the plants at the head of this list. They may
 grow well at first but soon become stunted and fail to bear well.
 The Station has developed a promising method of treating
 seed beds to exterminate the worms or at least greatly reduce
 their numbers. The material used is a mixture of calcium cyan-
 amide and other substances sold under the trade name of
 "Cyanamid." The method is described in detail in Bulletin 136
 of this Station, which will be sent free upon request.

 OTHER GENERAL PESTS
 The following named pests attack a large number of veg-
etables and could have been treated appropriately under this
general heading. They are: Fall army worm or grass worm
(see under corn, page 155) ; red spiders (see under peas, page
175); garden aphid (see under cabbage, page 144); and cut-
worms (see under cabbage, page 137).

 BEANS
 BEAN LEAF-HOPPER (Empoasca mali)*
 Several species of jassids severely attack snap beans, espe-
cially those planted early in the fall. Their ravages are often
so severe as to discourage the planting of beans at that season.
 Jassids obtain their food by sucking the juices of plants.
If the insects attack in sufficient numbers the plants will be-
come stunted in growth, fail to bear well, turn yellow and
finally die.
