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.

Damage to pastures often becomes very obvious in winter. Generally it is too late to prevent production losses which have already occurred, however pastures may be saved and long term quality maintained if pests are controlled.

If this is necessary, identify the pest and adopt appropriate control measures.

Bear in mind that spring growth is not far away and may outgrow the effect of the pest.
