选用不同化学杀菌剂和无公害药剂，对向日葵始花期、盛花期进行田间接种，调查病情指数计算防效。试验结果表明：混剂中甲托︰咪鲜胺（4︰6）配比效果最好，防效可达61.2%；单剂中防效较高的是40%菌核净 WP，无公害药剂中6%低聚糖素、5%氨基寡糖素、液体地膜的防效较好。田间防治向日葵盘腐防治以初花期防治效果好于盛花期防治。

Various chemical fungicides and pollution-free pesticides were chosen to make a field inoculation of sunflower on early-blossom period and full-blossom period, and the disease index was investigated and the control effects calculated. The results showed that in the mixtures, 40% thiophanate-methyl WP∶25% prochloraz ES (4∶6) had the best control effect which reached 61.2% . That got a higher control effect in the single dosages was 40% dimethachlon WP; In the pollution-free pesticides, 6% oligosaccharide AS, 5% amino-oligosaccharins AS and liquid film had good control effect. As the good prophylaxis and treatment period of sunflower head rot in the fields, the control effect of the early- blossom period was better than the control effect of the full-blossom period.
