Ground Beetles Reduce Weeds | haccp IT!
Ground beetles could play an important role in ensuring future food security by munching on weed seeds that would otherwise grow to compete with food crops. Researchers have found that ground beetles play a role in weed control in farmland soils. Using data from 257 conventionally managed fields throughout the UK, researchers determined the effect of ground beetles in the soils of sugar beet, maize and spring and winter oilseed rape fields. Seed predation by naturally occurring beetles in farmland does have a beneficial effect, reducing weed numbers in fields and potentially improving agricultural productivity. The research showed grass weeds were reduced more than other weeds. Many grass weeds have become resistant to herbicides and can have a major impact on productivity, competing with crops for resources.
