Weed & Pest Management News

Farmers who drilled oilseed rape in July and August without applying a pre-emergence herbicide will need a tailored approach to weed control this autumn.

Tower – a residual herbicide containing a unique mixture of pendimethalin, diflufenican and chlorotoluron – offers arable growers easy access to a three-in-one solution which is capable of controlling a wide spectrum of weeds.

Withdrawal of herbicide active ingredients is putting pressure on the remaining modes of action, warns ADAS weed specialist Dr Sarah Cook. Heather Briggs reports.

Mixed weather patterns across many regions of the UK and Ireland is leading to localised outbreaks of late blight in potatoes, according to Corteva Agriscience.

Many growers across the country are risking a serious escalation of their black-grass problems by failing to pay sufficient attention to key elements of cultural control, according to the latest national grassweed study run independently for Bayer this season.

Decisions taken during harvest can have repercussions 12 months later. With farmers determined to recover from a difficult 2019/20, what steps can they take to increase the chances of a successful crop next year? 

Resistant ‘super rats’ are breeding in the UK and more information is needed to reduce their numbers. A new survey will compile data to establish the extent to which resistance is understood and what methods farmers are using to control rodent infestations.

As the first signs of rust (Uromyces betae) and powdery mildew (Erysiphe betae) are reported in crops, growers should prepare to make the first of two fungicide applications advised by the BBRO to protect yield potential.

Farmers using Forefront T to control perennial weeds such as docks, thistles, ragwort and nettles to turn infested pasture back into productive grassland, must remember treatment comes with certain obligations.

The Chemicals Regulation Division (CRD) has approved the use of Funguran Progress to control late blight in organic potato crops.

After a challenging season for arable farmers, the window before harvest is an opportunity to check and map the black-grass situation to plan for the months ahead.

As exceptionally dry weather has meant poor early grass growth in many parts, forage supply may not meet demand for grazing cattle and sheep.
