Getting your weed control right in a difficult season with Zypar

Now that the land is becoming fit to travel, growers face the challenge of a large backlog of spray operations and fieldwork. Getting on top of grass and broad-leaved weeds should however be the priority in the coming weeks, before weeds become larger and more competitive with the crop.

Maintaining use rates should also be a consideration, as larger weeds will require higher use rates for effective control. In addition, many crops are also fast approaching the cut-off for safe use of phenoxy herbicides, which will limit weed control options. With reports of difficult broad-leaved weeds such as Cleavers, Cranesbill, Poppy, Shepherd’s Purse and Fumitory present in crops, choosing the right herbicide will be more important than ever.

Zypar® offers broad spectrum broad-leaved weed control and sets the industry standard for control of the most competitive weeds, including Cleavers, Cranes-bill, Fumitory, Mayweed and Brassica species. With applications permitted up to and including GS45 (30th June) on winter and spring cereals, except oats. Zypar offers a flexible window of application to the grower, beyond that of phenoxy and sulfonyl-urea herbicides.

If using Zypar on Winter Oats, the cut-off of GS32 is fast approaching, with reports of oat crops already at GS30. Users are reminded that there is a limited number of approved tank-mixes for use on Winter Oats. Remember that the maximum use rate is also lower at 0.5l/ha when using Zypar on Winter Oats. Zypar does have a wide range of approved and tested tank-mix compatibilities on other cereals, allowing growers to make the most of the limited spray opportunities and apply your tank-mix of choice. For advice and guidance on larger tank-mixes, growers should contact their local Corteva area manager or the technical hotline.

PT303 maintains high position on the 2023 AHDB UK Recommended List

PT303 Protector® Sclerotinia is the first hybrid offered to UK growers with a claim for Sclerotinia tolerance. It’s impressive disease package includes TuYV resistance, partial resistance to verticillium stem stripe and a score of 7 for light leaf spot and 6 for phoma. It’s proven its reliability with a gross output of 104% for the UK on this year’s AHDB Recommended List, with 104% in the East West and 102% in the North region. And with its yields achieved in years  when cabbage stem flea beetle activity was very high across much of the UK, PT303 has further proven its ability to deliver. This season, choose PT303 the UK’s all-round top performer.

Deploying Univoq in your fungicide programme

The Challenge
Early sown crops and conducive winter conditions have conspired to provide Septoria with a great start this spring. Add to this the wet weather through March, which will have restricted activity in most areas, and it is easy to see why growers are facing such a significant challenge as we start T1 fungicide sprays.

The Solution
It is for these reasons that many agronomists are now focused on where to deploy Univoq™ in their programme, with its unique mode of action, providing both curative and persistent control against S.tritici. When used at T2, it is often the long persistence of protection that is sighted as a key reason to use Univoq. With Septoria developing as rapidly as it is, some are considering whether these properties may be needed at T1 (GS32) with thought to catchy weather possibly delaying T2 applications and therefore the reassuring persistence of control offered by Univoq playing to their advantage at this application timing. With temperatures finally picking up we are starting to see Septoria take off too, so consider a rate of 1.1-1.25L/Ha if using Univoq at T1 depending on the variety and disease pressure.

Remember, Univoq may only be applied once within your fungicide programme. For those preferring to retain Univoq for the T2 timing, where the greatest yield response is likely to be generated, the rate of use will be determined by conditions at the time but are likely to fall in the range of 1.25-1.5L/Ha. Whatever the timing, growers are reminded of the stewardship advice provided which can be found at www.corteva.co.uk/inatreqadvice

Controlling broad-leaved weeds in potatoes with Titus

A wet March saw planters unable to travel and seed stocks stuck in sheds while almost 120mm of rain fell, representing 80% more rainfall than is typical for the month, according to Met Office data.

South West and South East England were the worst-affected regions, while growers in the North West and North East were spared some of the rain but battled more frosts and snow. The bulk of weed control workload in potatoes is carried out using residual chemistry applied to ridges shortly after planting. Weeds evading the scope of residuals are tackled with a post-emergence spray, typically in May.

Craig Chisholm, Corteva’s Field Technical Manager for potatoes, said: “There are three main reasons why weed control is important in potatoes. The first is protecting the crop from yield-robbing competitive weeds, and the second is ensuring harvest machinery is not hampered or slowed down. But perhaps the most important reason to keep weeds in check is to reduce the risk of blight through sheltering leaves or contributing to a more favourable microclimate.”

Craig advises growers who are unable to get their pre-emergence herbicides on to instead use a post-emergence approach as the crop encounters warming, moist conditions. Titus® is a sulfonylurea herbicide containing rimsulfuron for control of broad-leaved weeds in potatoes. Applied in mixture with metribuzin, it provides the most comprehensive post-emergence weed spectrum.

Apply BlueN and give your crops an additional source of nitrogen

Spring has sprung: crops are actively growing, it’s getting warmer outside, and the night frosts are gone opening up more opportunities to apply BlueN™ – a nutrient efficiency biostimulant which provides crops with an additional source of Nitrogen that is available throughout the plant’s lifecycle.

Providing 30kg of nitrogen per hectare on average, BlueN can enhance your crops for better yields. For the best results apply BlueN when plants are in the active growth stage, when day temperatures are over 10 degrees, and there are no frosts predicted before or after application. For more information click here.
