It is not advisable that potatoes be planted to the same land two years in succession. The crop for this year should be put as far as possible from last year's field. When the seed-bed is used, it is ad- vised that the young plants be sprayed once or twice with arsenate of lead, 4 pounds to 50 gal- lons of water. Time may be saved by dipping the plants as they are pulled

Figure 23.— Corner of a va- cant lot in Florida showing mat of wild sweet potato vines badly infested with the sweet potato weevil. It is not advisable that potatoes be planted to the same land two years in succession. The crop for this year should be put as far as possible from last year's field. When the seed-bed is used, it is ad- vised that the young plants be sprayed once or twice with arsenate of lead, 4 pounds to 50 gal- lons of water. Time may be saved by dipping the plants as they are pulled from the draw-bed. Some of the weevils while feeding on the young plants will be killed. This will effect a partial control in the field. So far as is known, no variety of potatoes is immune from the attack, although sweeter yellow varieties known in the South as yams are preferred, the Nancy Hall variety being one of the favorites. It is especially advised in order to eradicate this in- sect from the farm that no seed potato bed be put out, but that plants be bought from some reliable dealer or firm that have had their plants inspected and tagged by a state official, certifying that they are free from all insect pests or plant diseases. In the spring, as soon as the main stock of edible potatoes has been disposed of, the old store-house or bin should be cleaned up thoroughly. In this way sev- eral weeks should elapse between the. date of cleaning up (and that of setting out new plants. If any adulti weevils should be left, it is believed that they will be starved before this new food supply is brought 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 Hand, T.
