Cosmin recently dealt with the death of weaners on a Kale crop due to red water or SMCO poisoning.
Although this problem is normally seen in flowering crops on soils with high sulphur levels, this crop was not flowering although it had been stressed with excess soil moisture.
If feeding brassicas, always keep an eye out for the signs of red water. The best way is to watch cattle urinating and check urine puddles for red tinges as you shift the breaks. Affected animals will also be slow to move onto new breaks and eventually become staggery.
With this current run of weather, brassica crops are likely to bolt to the flowering stage earlier than normal. This may increase the risk of SMCO poisoning.
PS. High soil sulphur levels increase the risks of poisoning this cropping season. Ensure you use fertiliser programmes and products that do not supply levels of sulphur that are unnecessary for the crop and are likely to cause problems.
