Slugs are the slimy bane of many a farmer’s life, however their days of munching on treasured crops might be numbered due to a brand new device that predicts the place the pests will strike.
It’s the results of groundbreaking analysis from a consortium led by the British On-Farm Innovation Community (BOFIN).
One strand of the three-year, £2.6m challenge – funded by Defra – employed a community of ‘slug sleuth’ farmers working as area researchers to suss out the molluscs’ favoured soil varieties.
The monitoring has led to the event of a digital area mapping device, which pinpoints weak slug hotspots, which means farmers can deploy pesticides with new precision as a substitute of randomly treating total fields.
Growers participating in a pilot have been capable of slash the usage of slug pellets by a mean of fifty% consequently. Widescale adoption throughout the UK’s arable trade may save farmers £6m a yr, researchers estimate.
BOFIN founder Tom Allen-Stevens mentioned the brand new innovation was not the challenge’s solely main breakthrough. “Nobody has used farmers to assemble scientific proof like this earlier than, so one among our greatest findings is that farmers can do analysis,” he mentioned. “Farmers deserve extra respect for his or her intelligence: nobody is aware of the land higher.”
Slugs pose a £44m-a-year headache for farmers rising crops akin to wheat and oilseed rape. In addition to grazing on shoots, they munch the seeds of barley, oat and wheat, and might devastate total fields of greens.
Ferric phosphate pellets are the principle line of defence, however they’re a costlier therapy than the now-banned chemical metaldehyde.
Seeking an answer, BOFIN’s playfully titled ‘Slimers’ challenge (‘Methods resulting in improved administration and enhanced resilience to slugs’) recruited 28 farmers to watch the place the pests gathered of their fields by setting traps.
The information, alongside soil sampling, knowledgeable a pc mannequin, which farmers can now entry at no cost to supply their very own ‘slug threat’ map. That in flip will be plugged into an automatic pellet applicator that drops the pesticide solely the place it’s wanted.

Allen-Stevens cautioned that the research’s outcomes might have been favourably skewed by a low slug burden throughout final yr’s dry autumn, when trials came about.
“We’ve bought an enormous diploma of confidence within the mannequin, however we’d prefer to see it examined extra,” he informed Optimistic Information. “We’re asking farmers to obtain the maps, give them a go and see what they suppose.”
In one other strand of Slimers, scientists from the John Innes Centre labored with farmers to trial new slug-resistant wheat varieties. The work has pinpointed three areas of the wheat genome linked to resistance to the gray area slug.
“Slugs are one of many greatest challenges for arable farmers so creating wheat varieties with pure resistance would assist scale back crop losses and enter prices, decrease environmental affect and improve resilience,” Allen-Stevens added.
