- Abstract
When grapevine plants in a glasshouse were artificially inoculated with Botrytis cinerea and then treated with dicarboximides at different stages of bunch development, treatment at 80% cap-fall, with or without treatment before bunch closure, gave significantly better control than treatment at 3 weeks before harvest. In held trials early applications of procymidone reduced natural infection by B. cinerea better than late applications Spray application at pre-bloom followed by a second application during bloom is recommended. Procymidone, vinclozolin and iprodione at 1 g/l were significantly more effective in controlling natural infection than dichlozolinate, benomyl, captan, chlorothalonil and copper oxychloride.
