A NEW cereal fungicide designed to help UK farmers fight back
against growing disease resistance problems - by meeting the demand
for higher doses of triazole fungicide, combined with an anti-resistance
fungicide partner - is being developed by Syngenta
New cereal fungicide UK 282 - similar yield and disease control
levels to leading standard fungicides in extensive tests.
Known by its code name, UKF0282, the development product contains
two curative triazole fungicides shown to penetrate inside the
leaf, combined with the anti-resistance partner of Bravo (chlorothalonil),
which protects against fungal growth on the leaf surface.
Extensive testing of the new mixture - particularly against Septoria
tritici - in over 35 trials around the UK, has shown levels of
disease control and yields similar to those from leading triazole
However because UKF0282 contains active ingredients that are already
available, there have been none of the huge development costs associated
with bringing new active ingredients to the market, Syngenta points
Instead, twenty first century know-how has been used in creating
an efficacious formulation, it adds.
"Low cereal prices mean high yields from top disease control
are crucial with cereal production," says Syngenta cereal
disease specialist, Matt Pickard, "in order for growers to
maximise crop margins.
"Equally, though, with low grain prices, we know that growers
are looking for cost-effective disease control solutions.
"Trials have shown that programmes containing UKF0282 have
given Septoria tritici control and yields to match mixtures of
the triazoles epoxiconazole or prothioconazole with Bravo. In trials,
UKF0282 has also given similar brown and yellow rust control to
epoxiconazole with Bravo," he adds.
Tested in both wheat and barley, UKF0282 has been developed based
on the concept of triazole stacking. This is essentially the mixing
together of different triazoles each with complementary disease
strengths. "Chlorothalonil completes the armoury, providing
reliable control of all strains of Septoria tritici," Mr Pickard
"Similarly, research has shown that the two triazole ingredients
contained in UKF0282, cyproconazole and propiconazole, penetrate
and move through a cereal leaf at different speeds. The faster
moving fungicidal activity from cyproconazole is complemented by
slower moving activity of propiconazole to give more even leaf
Syngenta hopes to have the evaluation of UKF0282 completed by
the Pesticide Safety Directorate in time for the 2006 season.
