Pea and bean growers told to check for weevil
BACKWARD or thin crops of winter beans should be checked for pea and bean weevil, says the Processor and Growers Research Organisations Anthony Biddle. If the pests are feeding on new leaves, a pyrethroid spray is justified until the weather warms and crops start to grow away.
Peas are vulnerable to the pest up to the six leaf stage, but there are few reports of damage, he notes. If damage is obvious, a pyrethroid will reduce leaf feeding and disrupt egg-laying. Larvae attacking root nodules later in the season can cut yield by 10-15% in stressed crops, he adds. *
