ARIZONA (500 g/L folpet)

The multi-site fungicide that pays for itself

With resistance to single site fungicides hampering disease control, a multi-site active ingredient such as folpet should be used to power up crop protection programmes.

ARIZONA: the cost effective multi-site

Data from 54 trials conducted over four years suggests that, based on a wheat price of £220/tonne, the inclusion of folpet in spring fungicide programmes will deliver a five to six-fold return on investment by increasing yields by an average of 0.265t/ha. That’s as a result of prolonged green leaf retention which results in better grain quality and yield improvements of up to 0.6t/ha.

In the video below, Andy Bailey, ADAMA’s Fungicides Technical Specialist, explains how including ARIZONA (folpet) as a tank mix partner increases septoria control, improves green leaf persistence and protects the upper leaves in wheat to deliver a proven yield benefit.

    "As an industry we’ve recently seen an exciting and effective new mode of action come to the fore, and I think it’s important we ensure this continues to work well on farm for as long as possible: including a multi-site such as folpet is a good way of doing that."

    Luke Cotton, Independent Agronomist Cotton Farm Consultancy Ltd.
    "I used folpet again in 2022, not just because it gives a good yield response through stronger green leaf retention, but also because it performs an important role in terms of resistance management by ensuring the fungicide programme doesn’t rely solely on single modes of action which is a potentially dangerous position to be in."

    “We’ve always used a multi-site, which has been chlorothalonil, but the loss of that now leaves folpet as an essential part of the fungicide plan. We do need multi-site in the programme and folpet gives the best opportunity for that. Folpet will certainly be part of our resistance strategy and our overall fungicide strategy going forward”

    "I’ve used ARIZONA at T1 and T2 to help protect the new chemistry. With the continued decrease in efficacy of both azoles and older SDHI’s, protecting newer chemistry is more vital now than ever before."

FRAG-UK endorsement

Fungicide Resistance Action Group (FRAG-UK) recommendations

One of the key recommendations of FRAG-UK is to use multi-site fungicides – either as a tank mix partner or alternately with single site fungicides – to reduce the erosion of efficacy in single site and other medium to high resistance risk fungicides.

Multi-site fungicides are a valuable tool to manage resistance by preventing development to many pathogens… and can protect and prolong the lifespan of medium to high resistance risk fungicides like SDHIs... and can provide added levels and spectrum of disease control. FRAG-UK
