Effects of the green peach and bean aphids on table beet seed plants
Table beet seed crops are attacked regularly by the green peach aphid—Myzus persicae (Sulz.)—and by the bean aphid—Aphis fabae Scop. No definite knowledge about the kind and amount of damage to the seed crop caused by the aphids is available. Therefore growers usually apply aphicide sprays or dusts whenever the pests become obvious.
