摘要

A new test should prevent thousands of tonnes of wheat seed being treated with a fungicide seed treatment unnecessarily. One bunt infected plant in 10,000 wouldn't dent your yield. But left unchecked, the disease could affect one plant in four within three seasons, and that would cast a severe blow. To minimise the risk of this devastating disease in which grains are replaced by bunt balls, the majority of wheat seed is treated routinely with a basic fungicide seed treatment. Despite the obvious need to optimise input costs, it is considered moneywell spent. But for many growers it is not always necessary, suggests Valede Cockerell of the Scottish Agricultural Science Agency. In perhaps more than half of cases, there is no bunt present in the seedthat's being treated. It's a similar situation for seed-borne fusarium, though it tends to be more widespread than bunt. Seed infection is encouraged by cool wet weather at, or soon after, flowering. Presence of the seedling blight pathogen leads to poor establishment in cold seedbeds where germination is slow. Mrs Cockerell considers that the practice of routine treatment does not take account of increased consumer concerns about the use of pesticides. Pesticides should be used according to need, andthat includes seed treatments even though the amount of active ingredient is relatively small in comparison to other uses of pesticides.
