Scientists have taken a step forward in their efforts to tackle serious crop pests by reducing the sensitivity of biopesticides to sunlight Insect pests consume around a third of all the crops we grow, sometimes threatening food security. The main way of controlling these pests is by spraying chemical pesticides but these can be damaging […]
NIAB EMR, in a joint UK–China research programme, has discovered several strains of the strawberry disease Verticillium wilt (Verticillium dahliae), belonging to two different groups, that act in very different ways. The results are already being used by plant breeders in the development of a new generation of wilt resistant varieties.
Scientists have found diamondback moth (DBM) caterpillars surviving in UK Brassica crops this winter and are recommending growers check their own crops for the pest now. Previously considered a migratory pest, recent research from AHDB indicated that diamondback moths could be surviving UK winters. AHDB’s Dawn Teverson, and Rosemary Collier from Warwick Crop Centre have […]
UK herb growers will be able to protect their crops with a new weed control product in record time, following successful trials as part of AHDB’s £1.4m crop protection project. To achieve this approval so quickly, the team used intelligence from other EU countries, collaborating closely with other manufacturers and growers, to ensure trials on […]
The science behind the home-pregnancy test is now being trialled to detect the presence of diseases, which can devastate fields of vegetable crops, including the Christmas sprout. Trials are underway to help protect crops of Brassicas – sprouts, broccoli, cabbage – and onions, which generated more than £356 million for UK agriculture last year. Diseases […]
In a paper published today in the Proceedings of the Royal Society B: Biological Sciences, a team of researchers from Italy and the US record their study of the effects on honey bees of agriculture that exposes the insects to both poor nutrition (low quality nectar) and pesticides (neonicotinoids). “Our results provide the first demonstration that […]
In a government statement today, Michael Gove, Secretary of State for Environment, Food and Rural Affairs, says the UK supports further restrictions on the use of neonicotinoids because of their effects on bees and other pollinators. The announcement, says the statement, follows advice in October from the UK government’s advisory body on pesticides, the Expert Committee on […]
Researchers reported in the journal Science this week that tests for five neonicotinoid compounds found at least one in 75% of honey samples from 198 sites around the world.
Combining methods of disease control rather than relying on a single resistance strategy can extend the durability of crops by many years, confirms computer modelling that draws on classical population genetics theory.
Michigan State University‘s (MSU; USA) Robert Last studies tomatoes. Specifically, he researches their hair, or trichomes. For this study, he focused on a single type of molecule in trichomes – acyl sugars. The secrets Last and a team of MSU scientists found from studying these specialized metabolites open an evolutionary window for the emerging field of […]
