Winter crops are looking relatively well at this stage considering the extremely harsh weather conditions over the past six weeks. Crops are a few weeks behind in growth stage compared to last year plus there is a much varied pattern due to the difficult extended autumn sowing period.
Winter crops are looking relatively well at this stage considering the extremely harsh weather conditions over the past six weeks. Crops are a few weeks behind in growth stage compared to last year plus there is a much varied pattern due to the difficult extended autumn sowing period. Attention should now turn to developing and working through an appropriate fertiliser and spray programme.
The earliest sown wheat is just approaching strong growth stage 30 (GS30) and will soon receive its plant growth regulator (PGR) plus some Bravo and trace elements where needed. Late sown wheat crops that were not sprayed with an autumn herbicide must have herbicides like Pacifica or Broadway Star applied before receiving a PGR.
Compared to last year, there is very little disease pressure and no mildew or yellow rust have presented, however crops must still be carefully monitored. As we approach late April, T1 applications should be getting underway on winter wheat. T1 includes SDHI plus a Triazole plus Bravo. Getting the timing right is essential when applying the T1 and can be just as important as choosing the right product. Aim to spray T1 when third leaf is fully emerged. As growth stage 31 approaches, most crops should now have received their main split of Nitrogen (N).
This time last year, crops had their T1 (fungicide and PGR) applied, however this year most crops are only ready for a T1 now. In general, six rows and hybrids are very clean but more robust rates of fungicide must be applied on two rows in particular. Pay close attention to Cassia as there is plenty of Rhynco present this year.
Depending on sowing date, main splits of Nitrogen (N) will need to be brought up to 150kg/ha of N in the next week as these crops approach stem extension GS31. Spray wild oats separately as there is a risk of crop scorch if combined with a fungicide and PGR, especially where night and daytime temperatures vary considerably e.g. 15 degrees during the day and 0 degrees at night. Be careful not to apply PGR’s on crops where frost is forecast.
Winter oat crops have come through winter looking well. Very little disease has presented, therefore the main priority should be to take care of weeds and mildew along with some PGR on the more advanced crops. Final splits will need to be applied soon as crops approach GS31.
Winter Oilseed Rape
Oilseed rape crops will need their final top up of Nitrogen (N) before they become too tall. In the case of hybrids, it is still worthwhile to spray with some Caramba to give a shortening effect and to help the crop branch out. In general, crops look very good with some excellent yield potential.
