Greenhouse Hygiene Practices

Greenhouse Hygiene Practices

Horticulture NZ Conference August 5th 2021


This year I honoured to be hosting a panel of growers, for a thirty-minute discussion on greenhouse hygiene practices, at the Horticulture NZ conference held at Mystery creek in August.

 This will be a great opportunity to share various international industry standards and adopted protocols already used in New Zealand by our most diligent growers.  I will be joined by several leading NZ greenhouse vegetable growers that have been at the forefront of hygiene measures.  It will offer the opportunity to learn from their experiences which may help us consider other hygiene measures that we may not have applied in practice.   This will be a collaborative session using the best researchers which is of course growers.

With new viruses threatening the tomato industry growers are now having to look for every possible way to prevent the spread and identify vectors/pathways for these virus entering greenhouses.   This is not solely for greenhouse tomato growers but a conversation for all protected cropping growers.


I have added discussion points below.  Time is limited so if there is any specific points you would like discussed please e-mail me at stefan@grower2grower.co.nz
