Broadway Star gives excellent control of a wide range of a wide range of broad-leaved weeds in winter wheat crops.
The weeds controlled including cleavers, charlock, chickweed, groundsel and volunteer beans. It is also highly effective on wild oats and brome.
In spite of good post-emergent conditions for weed control last autumn, many crops now need urgent attention, according to Chris Maughan, technical manager with Whelehan Crop Protection.
He said cleavers are a particular problem and, if not controlled now, can severely damage yield. Just one cleaver plant/m2 will cut yield by 3%.
Wild Oats
There is no known resistance of wild oats to Broadway Star. This was confirmed in recent Teagasc research which demonstrated widespread resistance to the commonly used herbicides.
The research showed that between one and a half and eight times the recommended rates of ACCase herbicides were required in order to achieve around 50% control of wild oats populations.
In the case of one ACCase herbicide, 100% of the wild oats population survived after receiving eight times the recommended rate.
In contrast, an ALS herbicide was found to be effective on all ACCase resistant populations.
Broadway Star is an ALS herbicide and will, therefore, play an important part in the strategy to overcome wild oats resistance.
Advantages
“A huge advantage of Broadway Star is that it eliminates the need for complicated tank mixes of wild oats specific products and products effective against broad-leaved weeds.
“It can be tank mixed with a wide range of fungicides, trace elements and other herbicides. It can be tank mixed with a half dose of straight Chlormequat. If using any other growth regulator, allow a seven day interval,” advised Chris Maughan.
Application
The recommended application rate for Broadway Star is 265g/ha for brome and ryegrass and 210g/ha for broad-leaved weeds and wild oats.
It can be applied up to GS32. Target weeds should ideally be at the early tillering stage, wild oats and ryegrass at GS12-29 and volunteer beans up to eight true leaves.
It should be applied during a period of active growth. The use of an adjutant is essential. Torpedo is an excellent choice.
Ideal for Brome
Broadway Star is the perfect solution for brome, a growing problem in winter wheat crops, leading to yield losses of up to 40% where infestations are severe.
Research by Teagasc on 18 brome populations, collected randomly across the main south-eastern tillage counties, showed increasing tolerance or early stage of herbicide resistance evolution.
However, the research showed that Broadway Star when applied at the full rate of 265g/ha was effective on all 18 populations.
Chris Maughan stressed the importance of spraying brome before it passes the tillering stage – ideally at GS24 and before GS30.
“Active growth is also important. A minimum soil temperature of 8oC at 10cm a couple of days before and after application is required for good control,” he advised.

Broadway Star gives excellent control of wild oats and a wide range of broad-leaved weeds in spring wheat.
For effective control of a broad range of weeds in spring wheat, there is nothing to beat Broadway Star.
It gives excellent control of wild oats as well as a wide range of broad-leaved weeds including charlock, volunteer rape, volunteer beans, cranesbill, speedwell, groundsel, cleavers, pansy and wild carrot.
“A huge advantage of Broadway Star is that it eliminates the need for complicated tank mixes of wild oats specific products effective against broad-leaved weeds, making it a highly cost-effective product,” said Chris Maughan, technical manager with Whelehan Crop Protection which distributes Broadway Star on the Irish market.
It can be applied up to GS32. The application rate for spring wheat is 200g/ha in 130-150l water. The use of an adjutant is essential, of which Torpedo is an excellent choice.
No known wild oats resistance
Research by Teagasc in 2016 and 2017 identified populations of wild oats resistant to one certain herbicide. The 2017 research involving resistance testing of a panel of randomly sampled wild oats plants from across the county showed that around 55% were resistant to at least one herbicide active ingredient.
There is no known wild oats resistance to Broadway Star. For effective control, apply with the adjuvant Torpedo ideally at GS12-29 and before the first node emerges on the wild oats.
Killing brome in winter wheat
At severe infestations, brome can cut winter wheat yields by up to 40%. Applying Broadway Star when the brome is small - GS23-28 – gives best control. However, application at a slightly later growth stage can still give good suppression of the brome.
The application rate for brome and ryegrass is 265g/ha. For control of wild oats and broad-leaved weeds in winter wheat, a reduced rate of 210g/ha can be used. As with spring wheat, the use of an adjutant is essential
At a glance.
- Broadway Star the perfect product for wild oats and a wide range of broad-leaved weeds, including charlock, volunteer rape, volunteer beans, cranesbill, speedwell, groundsel, cleavers, pansy and wild carrot, in spring wheat.
- Apply at 200g/ha in 130-150l water in spring wheat, during active growth.
- Can be applied up to GS32.
- Target weeks should ideally be at the early tillering stage and wild oats at GS12-29.
- Can be tank mixed with a wide range of fungicides, including chlorothalonil, and with trace elements and other herbicides.
- Can be tank mixed with a half dose of straight Chlormequat only. If using any other growth regulator, allow a seven day interval.
- Always apply with an adjutant. Torpedo is recommended.
- Broadway Star can still give good control of brome and ryegrass in winter wheat crops. Best control is achieved when brome is small – GS23-28.
- For brome and ryegrass, apply at 265g/ha in 130-150l water.
- For wild oats and broad-leaved weeds in winter wheat, reduce rate to 210g/ha.

Galaxy is the ideal product for controlling a broad spectrum of weeds in cereal crops. It can be used on all varieties of spring and winter wheat, barley and oats.
It is highly effective in controlling corn marigold which could be a particular problem in the increased acreage of spring cereals this year. It is also powerful on mayweeds and thistles as well as a wide range of other weeds, including cleavers, chickweed, polygonums and charlock.
Therefore, when planning weed control, Galaxy, with its combination of three active ingredients (fluroxypyr + florasulam +clopyralid), should therefore be the preferred choice for inclusion in the tank mix.

Resistant Weeds
Galaxy has also the advantage of combating herbicide resistant weeds which are on the increase worldwide.
“The problem stems from overuse of acetolactase synthase (ALS) inhibiting herbicides, such as sulfonylurea (SU) herbicides, without a partner that works with a different mode of action,” said weed control specialist Chris Maughan.
“There are now some 100 species resistant to ALS herbicides across the world, including populations of chickweed, corn marigold, poppy and mayweed in both Ireland and Britain.
“Mixtures or sequences of herbicides with differing modes of action are important in preventing or overcoming resistance based on target site differences.
“Therefore, the addition of Galaxy to an SU will give improved control of many weeds as well as providing an alternative mode of action,” advised Chris, who is technical manager with Whelehan Crop Protection, distributors of Galaxy on the Irish market.
