Sweet corn and field corn ears are ruined by dull striped "worms", that devour and foul the grains when soft. This pest is related to the cutworms, and develops from eggs laid on the corn silks by brownish Fig. 12. Control:—Powdered arsenate of lead mixed half and half with slaked lime or plaster paris, and blown on the silks when fully showing, will kill the young larvae at first feeding. TOMATO WORM.

Control:—Powdered arsenate of lead mixed half and half with slaked lime or plaster paris, and blown on the silks when fully showing, will kill the young larvae at first feeding. TOMATO WORM. These large well known and destructive pests can be readily poisoned when young with lead arsenate. Hand picking of older larvae is best in small gardens. BEAN AND PEA WEEVILS. Stored beans and peas are usually attacked by weevils, which feed as grubs within the seeds, and leave large exit holes on emer- gence. Several generations may occur in a year, completely ruining the seed. Control:—As soon as beans or peas are dried and ready for storage, place them in a tight box or can, and fumigate for two or three days with carbon disulfide (see No. 10). Good success demands fumi- gation at temperature above 70 degrees Fahr. Keep away lights, because carbon disulfide gas is explosive. RED SPIDER. Tiny red or two spotted mites making a slight web on leaves of many tender plants, cause a Fig. Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Pennsylvania.
