Mr Hopley planned this spring’s fungicide programmes around last year’s farm trials and information he has drawn from local manufacturer and distributor trials visits, plus his Agrii agronomist. Utilising AHDB information and attending NRoSO, Cereals and CropTec events are also a valuable source of information.
Last year’s results from the Judge for Yourself trial on Graham and on-farm manufacture trials on Leeds were very promising, says Mr Hopley, who plans to modify his T2 strategy on both his feed and seed varieties which include KWS Kerrin, a variety which is prone to low specific weight.
“With barn-filling feed wheat I don’t want to be producing grain with a specific weight below 72 kg/hl.”
Comparisons between fungicides in farm trials have helped Mr Hopley identify which products and rates placed at T2 deliver the best return. As a result he plans to replace his 1.25 L/ha Aviator with 1.25 L/ha Ascra at this timing following impressive yields and specific weights between 2-4 points better than all other treatments last year.
“Ascra is going to be worth the risk in one field. All the crop has to do is to exceed 300 kg/ha increase in yield and not drop below 72 kg/hl to justify using it.
“Ascra works quicker than other products too. We were checking the crop every few days [last year] and the greening effect was very noticeable,” he notes.
|T2 Spray||Variety||Farm standard||Yield benefit Ascra (adjusted to 15% MC)||MOIC Ascra vs. Farm Standard (Based on £137/t)|
|Ascra 1.5 L/ha||Graham||Adexar 1.25 L/ha + CTL 1.0 L/ha||0.67 t/ha||£80|
|Ascra 1.5 L/ha||Graham||Elatus Era 0.8 L/ha + CTL 1.0 L/ha||1.45 t/ha||£184|
Selecting fungicide products that give the best returns and targeting them correctly is crucial to keeping a handle on fungicide costs for Herefordshire farm manager Mark Wood.
