Loss of CTL could result in 10% yield loss in barley - BASF conference
The farming industry was reminded of the potential impacts on ramularia control in barley with the likely loss of chlorothalonil from fungicide programmes.

Spring barley yields are likely to suffer yield losses of 10% if chlorothalonil (CTL) is withdrawn from the market.

The active has come under pressure within Europe in relation to concerns around its alleged carcinogenicity (capacity to produce cancer) and a suggested risk to ground water.

The active could be facing total withdrawal from the market or restrictions around timings and rates.

When floplet is added into the fungicide programme, losses of 6% are likely, but 10% is possible

Steven Kildea of Teagasc presented results from trial work carried out in 2016 and 2017 which showed yield losses of between 4.3-15% in spring barley due to the absence of CTL in the fungicide programme.

Losses would most likely be closer to 10%, he said.

When floplet is added into the fungicide programme, losses of 6% are likely, but 10% is possible, see Table 1.

Ramularia – a global disease

Prof Fiona Burnett of the SRUC discussed the prevalence of ramularia in Scottish barley crops.

Barley is the largest crop in Scotland and second in the UK and contributes significantly to the farming economy.

Ramularia is a significant problem in the southern hemisphere. Epidemics have been reported in New Zealand, Uruguay, Argentina and recently Tasmania

Fiona stated that while the disease is more common in spring barley crops, it can also be just as damaging to winter barley crops.

Ramularia is not a new disease and travels with the seed.

The disease is very closely related to septoria in terms of genetic make-up and one of its key strengths is its ability to over-winter on straw.

Ramularia is a significant problem in the southern hemisphere.

Ramularia can travel with seed.

Epidemics have been reported in New Zealand, Uruguay, Argentina and recently Tasmania.

In New Zealand, there is extensive succinate dehydrogenase inhibitors (SDHIs) mutations but demethylation inhibitors (DMIs) are still effective.

There is a mixed picture across Europe. UK and German activity from SDHI and DMI chemistry is compromised.

In Ireland and Denmark, there is still some activity from SDHI and DMIs. Interestingly there is no CTL in Denmark.

In South America they are still using SDHI, QoI and triazole mix with control appearing to hold.

2018 report

Last year, Teagasc published a report into the impact on yield and net margins in barley and wheat as a result of the loss of CTL.

The report indicated that yield loss in barley, in the absence of CTL, is likely to be between 5-11% and with production cost per tonne of spring barley (without CTL) increasing by between 5-11%. However, it also estimates that net margins could be decreased by a substantial 65% in the absence of CTL.

The annual industry conference is in its 10th year and is being held in the the Lyrath Hotel, Co Kilkenny today.

$2.4bn growth expected in biopesticides market by 2024
In a recent report, the emerging market is expected to grow significantly by the year 2024.

The importance of biopesticides in crop production is set to increase substantially in the near future.

Biopesticides are defined as certain types of pesticides which are derived from such natural materials as animals, plants, bacteria, and certain minerals.

Facilitate growth

With increasing pressure coming on conventional crop production in areas such as Europe and the US and with impending restriction in key actives such as glyphosate, this is expected to facilitate the growth of biopesticides.

In a report from Global Market Insights, it details how the value of the biopesticides market is expect to reach $2.4bn by 2024.

The low R&D expenses and ease of registration, along with government subsidies, will also encourage industry growth

The report states that rising pests and insects attack levels due to continuous climatic changes coupled with increasing demand for organic pest control will also be key drivers of the industry growth.

Furthermore, the low R&D expenses and ease of registration, along with government subsidies, will also encourage industry growth over the forecast period.

Biopesticide market at a glance

In 2016, the US biopesticides market generated over $550m.

Foliar sprays dominate the industry, accounting for more than 75% of the overall demand in 2016.

In that year, seed treatment applications were valued at over $130m.

Fruits and vegetables accounted for over 70% of the industry share in 2016, with rising awareness regarding nutritional values of food and healthy diet supporting the product penetration in this segment, the report says.

The report outlines how government, as well as institutional initiatives and promotions for product usage, will positively influence the product demand in this region.

Machinery in focus at AHDB monitor farm meeting in Downpatrick
A meeting was held in Downpatrick today focusing on machinery costs on Northern Ireland’s first AHDB monitor farm.

A meeting was held today in Downpatrick, Co Down, on the farm of Richard Orr focusing on machinery costs. Richard has been reviewing all aspects of his machinery outfit on his 75ha tillage farm.

“In doing the process of the review, I learnt as much as I did coming out of the far end, which was very interesting,” Richard explains.

In a preview of the meeting, Richard said that based on his review, some recommendations include getting rid of his sprayer as he was deemed to be over-mechanised.

However, his response was that this is necessary as due to the weather windows he contends with, in some cases he has to be over-mechanised to allow him to get the work done.

He concludes by saying that it is important to be able to justify machinery for your business and your farm needs and also to see how it affects your bottom line and whether it is a sensible investment.

See this week’s Irish Farmers Journal for a full report from the meeting.

Northern Ireland's fist AHDB monitor farm

Richard Orr is Northern Ireland’s first AHDB monitor farmer. He grows winter wheat and spring and winter barley on 185ac as well as potatoes, turnips and grass. His soil is predominately dry, free-draining medium, stony loam with good organic matter. Richard is in year two of the AHDB programme and there have already been multiple events on his farm.

$2.5bn growth expected in biopesticides market by 2024
In a recent report, the emerging market is expected to grow significantly by the year 2024.

The importance of biopesticides in crop production is set to increase substantially in the near future. Biopesticides are defined as certain types of pesticides which are derived from such natural materials as animals, plants, bacteria, and certain minerals.

With increasing pressure coming on conventional crop production in areas such as Europe and the US, and with impending bands/restriction in key actives such as glyphosate, this is expected to facilitate the growth of biopesticides.

In a report from Global Market Insights, they detail how the value of the biopesticides market is expect to reach $2.4 billion by 2024.
