Relation of time of planting potatoes to tuber flea beetle attack in Nebraska and Wyoming

Summary

It is obvious that late planting is a good means of protecting the potato crop from flea beetle attack. The later the crop can be planted with assurance of sufficient time to bring it to maturity, the less likelihood of serious beetle injury. Infestations on late plantings may be further reduced by applying insecticides on the early crop. The elimination of potato sprouts growing in cull piles, the destruction of weed hosts, and the omission of the early crop in areas, where practical, will also reduce spring populations, which would be a menace to late potatoes.
