Welcome to PestWebNZ™
PestWebNZ™ is a free tool to assist farmers and agricultural professionals in decision-making regarding weed and pest identification, biology, impact and management. PestWebNZ™ contains a number of New Zealand pasture weeds and pests, which have been chosen in consultation with key farming, industry and research personnel. We are adding more weeds and pests to PestWebNZ™.
PestWebNZ™ covers four main categories:
- Biology: the weed or pest life-cycle and where it is found;
- Impact: how the weed or pest affects your crops, pasture and livestock;
- Control: different methods used to control the weed or pest;
- Identification: use the identify tab to identify a weed, pest or its damage.
PestWebNZ™ was developed by the following partners, with additional funding from other sponsors.
