A seed treatment containing fluquinconazole as the only active ingredient was tested in sequences of up to six consecutive crops of winter wheat. It was applied or not applied in each year, and was tested in all possible combinations with treatments applied in previous years. Take-all was controlled effectively, and grain yield usually increased, when the disease intensity was moderate or severe in non-treated crops, but control of the most severe take-all did not result in acceptable yields or grain quality. Treatment of a first wheat or second wheat with little take-all did not usually benefit the subsequent crop. Non-treatment of a crop grown after a treated, diseased crop usually resulted in a marked increase in disease, indicating that treatment had delayed progress of the epidemic. Take-all was controlled by treatment of a crop grown after a treated, diseased crop but the amount of control and of increased yield was often less than that in a treated crop grown after a non-treated crop in the same crop sequence. Similar effects of seed treatment were apparent in crops grown on a site with take-all decline. The alternative fungicide, silthiofam, applied as a seed treatment in the later years of some experiments, was usually as effective as fluquinconazole. From these experiments, it is recommended that: a) fluquinconazole seed treatment should be applied to a second or third wheat crop, grown after a first wheat crop that was managed to avoid rapid take-all development (e.g. by avoiding very early sowing); b) a break crop should follow the treated crop; c) the seed treatment should not normally be used in longer sequences of wheat or on take-all decline soil unless it is planned to follow the treated crop with a non-cereal break.
