Planning autumn herbicide programmes to control grass weeds and broad-leaved weeds
It is tempting to think that once drilling is complete and a pre-emergence herbicide has been applied, you can shut the gate and not think about weeds again until the spring. Unfortunately, this is not the case for cereal growers who face the annual challenge of grass weeds and broad-leaved weeds.
Hugh Guinan, Corteva’s Field Technical Manager for Cereal Herbicides, shares essential strategies for managing these weeds in his latest article. Hugh discusses the importance of continuous weed control beyond initial herbicide applications, highlighting the challenges faced by growers and the necessity of a well-planned autumn herbicide programme.
Learn how to identify target weeds, choose the right chemical options, and time your applications effectively. The article also emphasises the benefits of integrated weed management (IWM), combining cultural, non-chemical, and chemical controls for sustainable and efficient weed control.
Whether you’re dealing with early-drilled crops or facing weather-related challenges, with some solid planning and best practices, you’ll be off to a good start in managing your cereal crops this autumn. Read more here.

How to control brome in cereal crops
Bromes are problematic, highly competitive grass weeds with good tillering ability, wide emergence patterns (depending on species) and good resilience to abiotic stressors.
Much like ryegrass, bromes are an increasing problem in the UK and Ireland, driven by increased use of min-till and no-till systems, close crop rotations and limited herbicide options.
Yield loss from brome results from direct competition but, due to the lack of control options in other crops such as barley and oats, they can be a challenge across the rotation.
One reason herbicide efficacy can be reduced is due to the plant’s physiology, the most common species have leaf hairs, varying levels of leaf waxiness and challenging leaf architecture in some cases, all making getting the herbicide through the cell wall to the target site more difficult.
Corteva trials have shown that the best control comes from a two-to-three spray programme across the autumn, targeting emerged brome when small, optimally when the weed has between one and three leaves. Key residual actives for control of bromes include flufenacet, triallate (pre-only) and pendimethalin. For emerged bromes, pyroxsulam (Broadway® Star) should be partnered with pendimethalin and applied as soon as application conditions are conducive to active weed growth.

Ympact seed treatment
With recent rain in some areas of the country delaying winter wheat drilling, it will be even more important as temperatures decline to give winter cereals the best chance for establishment going through the winter.
In a recent Corteva survey on seed treatments, 60% of respondents said they look for speed of establishment when choosing a seed treatment.
Ympact® seed treatment helps growers to give a great start to cereals early development speeding up emergence, enhancing root system development and improving crop vigour.
Ympact contains complexed micronutrients readily available for seeds. The uniquenessof the complex ensures the bioavailability of nutrients in early stages of growth andsupports plant development in various conditions.

Ympact is compatible with conventional seed treatments. Contact the technical hotline for further advice.

Kerb Flo 500 weed control in winter beans
Kerb® Flo 500 has an approval for grass and broadleaved weed control in winter beans. Apply pre-emergence within 7 days of drilling. Moist conditions are ideal with soil temperatures falling. Please follow stewardship advice for Kerb Flo 500 including considering buffer strips and grass margins.
Kerb Flo 500 can be applied pre-emergence with other products for effective weed control. Contact our hotline for further tank mix advice.

Belkar hotline questions this October
Belkar and canopy size
Belkar® has good flexibility for application conditions including working at temperatures as low as 2°C and will give effective control even where large crop canopies exist.
Can Belkar be mixed with boron crop nutrition products?
You can now mix Belkar with boron nutrition products. Please consult our latest compatibility list for information on all products tested as well as the boron products supported. Contact the hotline team if you need more information.
Does Belkar control volunteer linseed?
Arylex™ active demonstrates good activity against linseed up to 6-8 leaves. This can be delivered in 0.5L/ha of Belkar this autumn.

Propyzamide: Key information, resources and stewardship advice
It's October, so take the time now to remind yourself about the key information and stewardship advice from Corteva and The Voluntary Initiative ahead of autumn and winter propyzamide applications!
For more information about how to get the best from Astrokerb® and Kerb Flo 500®, visit our Propyzamide Knowledge Hub. We frequently add new resources, including a new CPD Course, to test your knowledge on propyzamide and stewardship. You’ll earn 3 BASIS points and NRoSO points and you could win some great prizes after you submit your quiz answers.
Our propyzamide stewardship webpage has been updated with simplified information to ensure that you are using Astrokerb and Kerb Flo 500 at the right rate, in the right conditions, and at the right time. These products are key to controlling grassweeds, especially blackgrass and ryegrass in oilseed rape.

The importance and benefits of using a silage additive
The autumn maize harvest is now well under way. It is important to consider the potential benefits of harvesting some of the crop for crimped grain maize silage. Considering the nutritional value of the crimped maize silage, adding a silage inoculant to enhance the fermentation process and ensure aerobic stability is an important step in the ensiling process. Pioneer® brand 11A44 will dramatically reduce heating within the silage pit. Shown to decrease yeasts and moulds to just 0.1% of untreated control silage, this product will improve fermentation and reduce dry matter losses when used on crimped maize at less than 65% dry matter.
In circumstances where a quick feed out is needed, our crimped grain maize inoculant 11B91 Rapid React® containing Lactobacillus plantarum and Lactobacillus buchneri will give the rapid drop in pH and the aerobic stability to allow feed out as soon as 7 days. The Lactobacillus plantarum in 11B91 Rapid React will also ensure a faster and more efficient acid fermentation than that achieved when using 11A44.
