Excessive levels of metaldehyde continue to be detected in water courses this winter

Wet weather throughout the autumn created ideal conditions for slugs. The challenging conditions have also meant that farmers have struggled to get winter wheat drilled. But the wet weather has delivered a double whammy, causing excessive water run-off in some areas.

Cereal farm trials to focus on IPM for harvest 2021

Harvest 2021 trials at AHDB Strategic Cereal Farms will focus on the prevention, detection and control of pests, weeds and diseases – key components of integrated pest management (IPM).

Surprise rodenticide resistance results prompt alert to farmers

Farmers are advised that the spread of rodenticide resistance rats has taken a “surprising and troubling” turn, according to Campaign for Responsible Rodenticide Use chairman Dr Alan Buckle.

Light leaf spot risk lowest for several years, according to forecast

AHDB’s light leaf spot preliminary forecast shows that the disease risk to winter oilseed rape (OSR) ranks among the lowest recorded in recent years.

Independent trials recognise best performing and most consistent bio-stimulants

Independent trials conducted in drought prone soils, comparing the performance of commonly used bio-stimulants on Skyfall winter wheat with a 50% fungicide programme, have found AminoA FLO to be one of the best performing and most consistent bio-stimulants in the study.

Count the days to CSFB larvae control

Oilseed rape growers and agronomists can now calculate the optimum timing to target cabbage stem flea beetle larvae hatch, with the chance to limit stem infestation.

AHDB forecast shows early onset of phoma in oilseed rape

Some winter oilseed rape may already have 10% of the crop showing phoma symptoms and may need treating, according to AHDB’s forecast for the disease.

Hold nerve with blackgrass infested fields

Continue to hold off drilling winter wheat fields where blackgrass is a worry until early October where possible, or mid-October in the worst fields, says agronomy firm ProCam.

Herbicide strategies to safeguard OSR viability

With many new crops of oilseed rape already in the ground and the remainder of a predicted winter crop of just 300,000 ha following close behind, the current focus is on maximising establishment rates and safeguarding the ongoing viability of crops by reducing the competitive pressure of volunteer weeds. ADAMA’s Bill Lankford shares his thoughts on the latest herbicide advice and active ingredient recommendations.

Bayer’s SpotCheck initiative returns to help oilseed rape growers combat light leaf spot

Bayer’s SpotCheck initiative, which helps oilseed rape growers identify light leaf spot (LLS) and other diseases in the crop, will re-open to receive leaf samples from October. The previous season saw epidemic-levels of disease so growers are advised to be alert to early signs of LLS and apply fungicides early.

OSR resurgence coincides with CSFB activity

Growers taking advantage of warm soils and good growing conditions to plant extra oilseed rape area, or with later emerging plants, should be aware of increasing cabbage stem flea beetle activity.

Keep beneficials in mind when tackling pests this autumn

With the loss of neonicotinoids forcing growers to change the way they tackle pest control in cereals and oilseed rape, pyrethroid insecticides now form the backbone of many aphid and flea beetle control programmes.
