The work of Agrovista at the Growcrop Gold Sites has clearly shown how various establishment techniques and seed rate interactions can have a major impact on rooting and subsequent yield in winter OSR.
As a development concept we have now established the correct plant density. The next stage of development is to further exploit the potential for increased rooting. The idea product for this should also deliver autumn disease control of light leaf spot and Phoma spp.
During the autumn of 2013 Agrovista Development evaluated a new product Frelizon (which contains the SDHI penthiopyrad and picoxystrobin) to examine these factors.
We know how effective these actives are in cereals and previous trials have shown that this class of chemistry had merit in OSR. This development project was particularly interesting in that we could now examine autumn applications of these two actives (an SDHI and a strobilurin), in winter oilseed rape.
Work by DuPont has clearly shown how effective Frelizon can be at increased rooting. This could be a vital factor in taking further our seed rate work and winter establishment.
There is very limited new chemistry available for autumn applications in oilseed rape, basically triazoles.
Frelizon with the complementary SDHI and strobilurin components will bring new opportunities to help control the main autumn pathogens. The SDHI (Penthiopyrad) component will offer very good control on Phoma spp, and the strobilurin component (Picoxystrobin) will be effective on light leaf spot.
