Get ready for spring grassweed control with Broadway Star
Favourable autumn and winter conditions for cereal growers will not negate the need for a herbicide this spring in most cases. As temperatures rise in the coming weeks, flushes of weeds will appear.

Broadway® Star delivers an outstanding performance in winter wheat, winter rye, triticale and spring wheat against yield robbing grassweeds including wild oats, ryegrasses and bromes PLUS the bonus of controlling an extensive range of broad-leaved weeds.

How to make the most of Broadway Star:
  • Leading product for ryegrass, brome, oats and broad-leaved weeds
  • Use as part of a programme
  • Use with a residual partner
  • Apply to small, actively growing weeds
  • Ensure optimal application techniques are followed
If conditions are suitable for applications of Broadway Star, adding a residual is generally beneficial in programmes until the end of February, providing soils still hold enough moisture.

Broadway Star is suitable for control of spring germinating bromes, meadow, soft and rye brome (GS11-29). It has a wide window of application up to GS32 inclusive and is suitable for early spring control of wild oats (GS11-31).

As well as grass weeds, Broadway Star controls a wide range of broad-leaved weeds including poppy, cleavers, brassica weeds, cranesbill, groundsel, speedwells, pansy and many more and a wide range of tank mix compatibilities.

Spring clean your oilseed rape with Korvetto
A solid autumn programme will have kept key problem weeds at bay, but early spring is an important time to monitor the emerging burden in the field as the crop opens up.

Korvetto® has excellent activity on the weeds that steal yield and cause issues at harvest. It contains Arylex™ active – the same active ingredient used in autumn herbicide Belkar® – in formulation with clopyralid. The application window is from 1 March to growth stage BBCH50 (flower buds visible from above the crop).

The added strength of Arylex in the formulation means Korvetto has unrivalled activity on those familiar red-faced weeds – poppies, mayweeds, cleavers and thistles – that become visible above the crop as the season progresses. There are no following crop restrictions, and farmers are free to use 1L/ha of Korvetto if they have applied a post-emergence herbicide in the autumn such as Belkar or AstroKerb®.

Trials data shows impressive yield advantage for Univoq fungicide
After just one season of extreme disease pressure, Inatreq™ active has already proven its ability to control Septoria, keep crops greener for longer and ultimately, deliver fantastic yields.

Univoq® fungicide has shown it delivers an average yield benefit of 0.25t/ha over Revystar® XE.  Across 36 sites in England and Scotland, Univoq outperformed the previous market standard in more than 80% of trials*. The uplift in yield from using Univoq is calculated to be worth £50/hectare to growers.

2021 was a high disease pressure year, and we know that Univoq’s major strength is septoria control, so it gave the fungicide the chance to really show what it is capable of. We have seen this excellent yield response from Univoq for many years, so this is not a surprise, but the data presented from last year’s harvest shows a clear advantage which can be directly linked to a greater return on a grower’s investment. *Read the full article here.

Many farmers have already used Univoq and you can find out about their positive experiences here.  
New Inatreq™ learning centre launched
Last Friday we launched our new Inatreq learning centre, an online resource for farmers and agronomists to earn CPD points while learning about our innovative new cereal fungicide molecule.

Viewers can watch the series of video presentations before answering multiple choice questions online to qualify for BASIS and NRoSO CPD points. 

To celebrate the launch, we’re giving away Inatreq active 8000mAh solar power banks with built in flashlight to the first 100 people that complete all 5 online quizzes correctly.  

Start your learning journey or top up your knowledge. Visit the Inatreq learning centre here.

Maize grain trial summary
Pioneer hybrids suitable for grain production are tested every year in PACTS Trials. The multi-year grain results summary prepared after the PACTS trials in 2021 are shown below.

Hybrid selection criteria for grain use are different from silage use. Grain yield, earliness of maturity, standing power, incidence of stem based diseases - especially fusarium - along with ease of harvest are key factors to consider. Likely maturity at harvest and grain moisture content should be carefully taken into account when selecting the hybrid to grow according to whether the harvested grain is going to be dried or crimped and ensiled as moist feed. 

For those growers looking for an early maturity hybrid P7326 has proven to be a popular choice. P7326 combines good standing power and extra early maturity with an easy to harvest ear. Another hybrid with very early maturity that can be considered in P7034.

For situations where a later maturity hybrid can be sown both P7948 and P8329 may be appropriate. In both cases yield potential is very high however the site selected needs to be very favourable and a late harvest date must be expected.

For the results of individual grain trials from 2021 please check out the 2022/23 PACTS Book and do not hesitate to give us a call if you would like advice about hybrid selection for your particular site and situation.
