Our online APP: Pacific Pests, Pathogens & Weeds

When crop pests and diseases occur, farmers want help and advise immediately. They don’t want to wait and in many cases, they cannot wait. Unless they act quickly, the crop could be ruined.

This App gives extension staff and lead farmers all the information they need to treat the crop. If there is no way of saving a crop, the steps should help to prevent the problem from occurring in the future.
