AgResearch has launched a website to help farmers fight serious pasture weeds and pests.
It provides information on the identification, control, biology and impact of key pasture weeds and pests.
An alert service also emails subscribers about outbreaks or potential outbreaks of pests, along with suggestions on how to manage them.
AgResearch scientist Colin Ferguson says the website covers more than 30 key pasture weeds and insect pests, with more to be added in the future.
The website can be found at www.pestweb.co.nz.
