Biodiversity and the environment
Growers have little choice - if they want a good crop they generally need use fungicides,
herbicides, insecticides and sometimes PGRs.
For instance, growers are forced to spray up to 15 times a season to keep late blight
in check. There are question marks against most fungicides on human and wildlife
On much traditional potato growing land, yield-damaging nematodes are now present
– forcing farmers to use less suitable land instead – often with a 15-20% yield penalty.
If herbicides are not used, weed control becomes dependent on cultivations, with
negative impacts of soil structure and sometimes an increase in soil erosion.
