New fungicide and herbicide products launched at Cereals

New crop protection solutions have been thin on the ground in recent years, but there were a number of new products introduced at Cereals.

New crop protection products were launched at #Cereals

Bayer has seven new products coming to the market in the next two years, the first two of which were introduced at Cereals.


Hamlet, a new post-emergence black-grass herbicide, will be launched this autumn and Ascra Xpro, a new SDHI fungicide, will be available in spring 2017.


Phillippa Overson, herbicide campaign manager, said: “In wheat trials, Hamlet gave significantly better black-grass control than Atlantis and also gave better control of ryegrass and broad-leaved weeds.”


Hamlet is a liquid formulation built around Atlantis active ingredients mesosulfuron and iodosulfuron, but also contains diflufenican (75g).


It contains more iodosulfuron than Atlantis, said to make it good against ryegrass. The optimum timing for use of Hamlet is in autumn at the one- to three-leaf stage of black-grass.


The new product is claimed to give an uplift in black-grass control compared to Atlantis of five to 10 per cent, but will need to be used in a programme.


The product carries similar following crop restrictions to Atlantis and Bayer is flagging up a risk to oilseed rape, particularly crops established with no-till.


Ascra Xpro is claimed to be the first wheat fungicide to contain two SDHI active ingredients.


Nick Duncan, cereal fungicide campaign manager, said: “Ascra Xpro contains bixafen and fluopyram, plus the industry standard azole, prothioconazole. In our work to date, it has given a clear benefit in disease control over current market products, which has translated into a 0.3 tonnes/hectare yield advantage.”


Bayer will be targeting the T2 fungicide market with Ascra Xpro and Aviator (bixafen+prothioconazole) will become its choice for T1.


Both products are approved for use and will be available for the 2016/17 season.


Further down the line, future innovations from the company include a new nematicide for root crops and Conviso Smart, a herbicide tolerant system for weed control in sugar beet.

 


New SDHI fungicide trials show higher yields


An SDHI fungicide incorporating new chemistry active against septoria and rusts has been shown to significantly increase green leaf area and yield in UK-based trials involving a number of different wheat varieties and situations.


Solatenol, launched by Syngenta at Cereals, has taken 16 years to develop, said Jason Tatnell, Syngenta technical expert.


He said: “We found Solatenol in 2005. It entered field trials in 2010 and European field testing in 2012.”


The product is designed to be mixed with prothioconazole and offers up to 0.6 tonnes/hectare (0.2t/acre) yield advantage over competitor products, according to Syngenta.


Solatenol is currently going through the final approval process and the company hopes to have gained approval and have product available for use on-farm next spring for T2 applications, said Syngenta technical manager Iain Hamilton.


Cereal fungicides campaign manager Andrew Curtis said: “Tremendous research and development investment has gone into the Solatenol project and this has given us a complete understanding of how Solatenol works.


“It consistently performs well as a fungicide, providing complete leaf protection inside and outside the leaf.”


Broad-leaved weed active


A new broad-leaved weed herbicide active ingredient, which works almost regardless of weather, made its debut at Cereals following a launch to market earlier this year.


Pixxaro EC (Arylex Active+fluroxypyr) is the first product to be marketed in the UK containing the new active, halauxifen-methyl. The combination tackles a number of key weeds, including cleavers, poppy, cranesbill, fumitory and fat hen.


Marketed by Dow AgroSciences, the new herbicide is the first new broad-leaved weed control active to be introduced for many years.


Dow cereals herbicide specialist Stuart Jackson said: “Arylex cuts through traditional limitations associated with other synthetic auxins. It works in cold and warm weather and when weeds are growing fast, slow or in a stop-start fashion.


“At a time when broad-leaved weed herbicides, such as HBNs, are being withdrawn, we are excited to be bringing a new active ingredient into the UK.”


According to Dow, the new herbicide delivers robust efficacy throughout the whole application window, which can start as early as February 1 or at GS13 running through to GS45 (second node visible) in winter-sown crops.


In spring cereals, applications commence from March 1.


With no ALS chemistry in the product, there are no restrictions on tank mixes or sequencing and no major following crop restrictions.
