Potato Review

CONTENTS www.potatoreview.com POTATO REVIEW MAY/JUNE 2023 3 Editor’s letter NUTRITION and disease management feature strongly in this May issue of Potato Review, and we have a number of di erent features looking at strategies, trials and overall observations. e bene ts and practicality of spreading straw mulch and applying mineral oils to the crop canopy are compared to the use of a pyrethroid insecticide in one article, while considerations and trial ndings to take into account while planning the most e ective blight programme for 2023 crops is covered in another. Andrew Goodinson considers the merits of foliar feeding and biostimulants this season while Agronomist Andy Aspinall discusses optimisation of crop health and manufacturers and industry associations comment on actions growers can take following Defra’s new ruling on urea. Fenland and Yorkshire growers share their experiences, revealing how fertiliser applicationmethods have been perfected, with phosphates and biological strategies boosting their crops’ health. Looking at climate e ects, specialists predict a higher risk of PVA and PVY in 2023 following a dry season last year while heat stress trials reveal how seaweed can play its part. In the rst of a series of new columns, Graham Bannister explains why he feels the newly-formed GB Potato is a valid representational body for the industry, and we also detail how new funding is impacting on a programme looking at tillage machinery and cultivation practice. In our PCN update, Bayer specialists look at protecting yields while preserving land for the long-term. We’ve also got the latest machinery and agtech updates for you to peruse, and plenty of information about how overseas potato markets are faring.
