Studies were made at Presque Isle, Maine, 1962–1966, to determine the suppressive effects of several materials against spread of the potato leaf roll cirus,Corium solani Holmes, transmitted by the green peach aphid,Myzus persicae (Sulzer), when applied as foliar sprays to Kennebec, Green Mountain, or Chippewa potatoes in field cages or in field plots. The early cage tests showed that spray mixtures containing 1% of the systemic plant growth regulant chlorocholine chloride (2-chloroethyltri…

Exploratory tests to prevent leaf roll infection transmitted by aphids

Experiments were conducted to determine whether single applications of foliar sprays of several substances would affect spread of leaf roll virus by the green peach aphidMyzus persicae (Sulzer) to potato plants of the Chippewa variety growing in cages in the field.

Potato leafroll virus — Effect of date of inoculation on percent infection and symptom expression

SummaryInoculation of field-grown Russet Burbank potatoes with leafroll virus during late June and early July resulted in nearly twice as many infected plants and four times as many infected tubers

Spread of Potato Virus Y curtailed by Oil

The finding that aphids carrying potato virus Y seldom transmit it after probing a surface lightly coated with oil offers a novel way of bringing this spread under control.

The use of ethylene chlorohydrin for breaking the rest period of large quantities of potatoes

SummaryResults of treating about 3,000 bushels of potatoes a year with ethylene chlorohydrin to break the rest period have indicated that varietal differences exist, necessitating variations in the
