Look for and note porina flights as these can indicate when to adopt control measures later if required. The most cost effective time for control is 8-12 weeks after the main flights which may occur in November, mid-January and/or late-February/early March (especially central North Island).

Consider direct drilling to control pests

For pastures badly affected by either grass grub or porina over winter and needing renewal, consider direct drilling. This will preserve naturally occurring diseases of these pests that are building up in the soil and which will provide long term population regulation. Leave sowing as late as possible as both pests, especially in the south, may still be feeding and could devastate establishing seedlings. Be aware that slugs and clover root weevil may also be present in damaging numbers.
