Spot-treating large perennial weeds such as brambles, gorse and broom in summer will catch them at the right time before they start dying back for winter, giving the best results according to Dr Nicola Perry, weed biology specialist for Corteva Agriscience.

Resistance strains to the highly popular blight fungicide fluazinam developed in the UK population probably because of over use of a single active. Looking at The Pesticide Usage Survey, going back several years, the usage of fluazinam has been as high as 384,000 hectares in 2010.

The Bayer Pest Solutions Team is highlighting the importance of preparing stores and protecting grain to ensure higher quality and value, as exceptional circumstances continue to affect the market.

Hutton periods are now being recorded in England and the focus needs to shift to blight control in potatoes.

LEAF (Linking Environment And Farming), one of the leading organisations promoting more sustainable farming, has today launched a new technical guide to support farmers in more ecosystems-based approaches to crop health and protection. 

ADAMA has today announced the launch of a new ferric phosphate-based professional molluscicide aimed specifically at controlling slug populations in UK growing conditions.

Cereal growers are being urged to spray off patches infested with black-grass now, before more plants set viable seed. The stress of hot dry weather has brought forward seed maturity, with viability set to accelerate over the next few weeks.

The wide range in winter wheat drilling dates and differing development speeds of some varieties are contributing to making this one of the most complex seasons ever for timing flag leaf sprays, experts are suggesting.

Impressive trials performances by a new co-formulated blight fungicide could give growers confidence that they can stay on top of the disease this year.
