2017 - Folpet: the multi-faceted multi-site
As well as its efficacy as a protectant against Septoria, folpet also offers the following benefits in curative situations:
- Folpet doesn’t interfere with the uptake of partner products
Trials have shown that, when used in conjunction with azoles, folpet does not affect the uptake of partner products – an important factor when maximum curative activity is required.
After 10 hours:
- When mixed with chlrothlonil, only 45% of epoxiconazole is absorbed
- When mixed with folpet, 55% of epoxiconazole us absorbed
After 25 hours:
- Epoxiconazole continues to be absorbed further when mixed with folpet, reaching 70% absorption after 25 hours
Additional trial works shows similar results when using folpet in conjunction with SDHIs – the uptake of the partner product is not adversely affected by the inclusion of folpet.
- Folpet improves yellow rust control
Arizona (500 g/l folpet) can help to improve yellow rust control at T1 and aids green leaf retention. This can translate to a 0.79 t/ha yield benefit when using folpet compared to chlorothalonil.
Similar yield benefits are also seen when using Manitoba (Adama’s co-formulation of 50 g/l epoxiconazole and 375 g/l folpet): this again shows that folpet is the ideal multi-site product, especially at T1 where yellow rust is an issue.
