Crops are looking strong as spraying nears its end -- pity about the weather
Crops are looking well, spraying is almost finished, price prospects are still improving -- pity about the weather.
Most winter wheat crops still have two-to-three clean leaves and have received their final head spray, which should reduce the fusarium risk presented by the continually wet weather.
They still need to be monitored for aphids and mildew, however.
Mildew levels are particularly high in Lion. Slugs are grazing the flag leaf in the same crops and in some cases can be found on the head.
Winter barley is filling well but botrytis is evident in upright ears. Most oilseed rape crops are leaning/lodged and I am concerned that pods which are buried in the crop will not fill.
Meanwhile, annual visits to commercial product and variety trials have commenced. Last Thursday at Dupont's trials in Rathangan even the control plot, which received no fungicides, still had two-to-three clean leaves. This proves that it has been a very disease free year so far, but humid conditions this week are likely to change all of that.
Their new SDHI looked promising and the task is now to identify which triazole will be the best partner. The inclusion of chlorothalonil is a must. The addition of a new SDHI to the armoury is most welcome, as we are reliant on new product development for the future of the industry. It will also increase competition and hopefully help to reduce prices.
I have found fungicide programme costs on winter wheat ranging from €74/ac, for non SDHI, to €119/ac where two SDHIs were used.
