GroGuard Features Using GroGuards Technical Reports About us Contact Us
The vine on the right was planted as a cutting just
20 weeks before this picture was taken. This
increased growth is typical of vines grown using
GroGuard vineguards. The vine has required no
trimming of laterals to reach the wire - vastly

reducing the labour costs normally associated with

getting vines to the wire.

Our vineguards are designed specifically to suit
Australian viticultural practices. Available at
common cordon wire heights or custom made to

GroGuard’s Strength
Keeps the GroGuard on the Wire

The GroGuard is wind tunnel tested, holding to 100 kph. Figure 1. GroGuard's unilateral vineguard at 100 kph in a wind tunnel. (Bricks and covers are keeping sand in place in the tray.)

GroGuard’s Rigidity
Drastically Reduces Training Costs

GroGuard’s rigidity prevents buffeting from the strongest winds. That encourages the growth of the main shoot and suppresses lateral shoot growth. Training costs are drastically reduced.

GroGuard’s Zip-Safe Seal
Fast Assembly

The patented Zip-Safe seal means rapid assembly using specially designed hand tool.

GroGuard’s Zip-Safe Seal
Improves Weed Control, and Reduces Costs

The patented Zip-Safe seal is waterproof. Herbicide cannot enter through the Zip-Safe seal, and shoots do not grow through it. Problem weeds can be dealt with easily. Tractor ("boom-spray") application of herbicide is normal with the GroGuard. It is cheap and covers large areas in a short time. In windy weather, early morning and dawn sprays make weed control possible while unsheltered vines are still struggling with weeds.
