Download PDF Nematodes and late blight are two of the big problems facing potato growers. CPM catches up on the latest research seeking to understand their dynamics and the regulatory changes that may affect agronomy decisions in 2021. The vast majority of soil nematodes are beneficial. By Lucy de la Pasture During December, AHDB hosted Agronomy Week, a virtual platform put in place of the usual annual Agronomists Conference. Highlights included a session by Dr Roy Neilson, rhizosphere ecologist and a key member of the team leading Integrated Pest and Disease Management research at James Hutton Institute (JHI). Roy presented details of a new three-year BBSRC-funded research project being carried out at JHI which aims to establish the link between plant parasitic nematodes and blackleg, one of the most economically significant potato diseases in the UK. He pointed out that nematodes form an important part of soil biology, with a biomass equivalent to 80% of the global human population. That equates to more than 57 billion per human being on the planet. “So great are the number of soil nematodes that the quantity of carbon they respire is roughly equivalent to 15% of carbon emissions from fossil fuels. “While agriculture…
