We Still Have LawnGard Prills

Those whose lawns have suffered from the attacks of grass grub and other lawn pest will know the effectiveness of Diazinon, the active ingredient in kiwicares lawngard prills.

Grass grub is found throughout New Zealand and is considered to be New Zealand’s major pasture and lawn pest. Grass grub lawn damage shows as patchy areas of dead grass; usually seen from March.

Eggs of the New Zealand grass grub are laid in the soil during summer; normally hatching after about 2 weeks. The small larvae then feed on the roots of grasses until spring, growing to 20-25mm long. Infested turf and pasture turns yellow and dies off leaving a dead mat of turf.

In October, November and December when the adults emerge from their pupae, massed flights of soft buzzing slow flying beetles often occur on still warm nights. Later these bronze beetles congregate in huge numbers, they feed on fruit trees and shrubs which are often severely defoliated.

During the late autumn and winter the grubs do not eat in the top 5cm of soil. The grubs are usually found about 15cm below the surface and control of the grub requires getting insecticide to this level in the soil. Treatment is most effective from February to March.

Apply Lawngard Prills on the grass paddock and lawns you wish to protect from grass grub. Ideal for use from February to late Autumn but can be used effectively through to Spring. The prills must be watered in, so sprinkle before moderate to heavy rain (13mm) or water the area thoroughly after treatment with a sprinkler.

Get it quick though as availability is only while stock lasts. Diazinon/Lawngard Prills will not be available to anyone without an approved handlers license after July 2015.
