HOW TO CONTROL PORINA

To get rid of porina caterpillar:

Apply LAWNGARD PRILLS on the grass paddock and lawns you wish to protect from porina at the rate of 100g per 40m2. Ideal for use from spring to late autumn. The prills must be watered in, so sprinkle before moderate to heavy rain (13mm) or water the area thoroughly after treatment with a sprinkler.

To control adult moth spray foliage of affected trees and shrubs with SUPER SPECTRUM between October and January.

About

The adult porina moth lays eggs on grass in spring. On hatching the caterpillars move to leaf bases where they feed. As they grow they burrow into the soil and emerge at night to feed on leaves. They do most damage in autumn and early winter. Porina is the more easily controlled pest and the treatment recommended below will control both pests.

Did you know

Similar lawn grass damaging insect larvae include grass grub, armyworm, leather jackets and greasy cutworm.

The scientific name of porina is - Wiseana cervinata
