摘　　要：１９８９～１９９３年，通过对３９种杀菌单剂、复配剂药效试验和药剂防治适期及次数试验，筛选出了防治稻粒黑粉病的高效药剂为黑粉净，其次为灭黑１号；得到药剂防治的适期和最佳次数为重病年盛花高峰末期和抽穗始期各施药１次；轻病年盛花高峰末期施药１次。１９９２～１９９４年大田示范、推广结果表明，采用本套药剂防治技术，相对防效达６０．０２％～８１．９９％，制种产量增加１６．３８％～１７．５７％。The frequency and times of application of 39 fungicides were experimented during 1989～1993 in Sichuan province. The results as follow: ① Hei-fenjing was the most optimum fungicide to control rice kernel smut disease among the single and compund fungicides, the second was Meihei-1. ②The optimum period of chemical control were at beginning of heading stage and end of blooming stage. The fungicide was applied for once at the end of blooming stage during slight disease year, and the fungicide was used at mentioned above two stages during serious disease year respectively. Efficiency of rice kernel smut disease control was 60.02%～81.99%,and the yield of hybrid rice seed was increased by 16.38%～17.57%, when the techniques were applied in hybrid rice seed production during 1992～1994 in Sichuan, China.
