Potato aphids feed by sucking plant juices
from the stems, veins, growing tips and blossoms. Injury from feeding
by potato aphids can weaken and stunt the plant reducing yields.
Seldom is injury severe enough to kill plants but heavy infestations
will turn foliage brown and the plant will start to die from the
top down. Damage resulting from the transmission of plant-infecting
viruses is usually much more dramatic than direct feeding injury,
which varies with the specific crop and disease. Early season infection
stunts plants and infection in seed potatoes results in unmarketable
crops. Some potatoes also develop a brown discoloring inside which
reduces quality. |
