| Abstract: | Efficacy and yield enhancement effects of eight against Ustilaginoidea virens(Cke)Tak were tested.The results showed that if spraying in both rice break period and complete heading stage,the control efficiency of 30% Difenoconazole · Propiconazole EC,43% tebuconazole SC,Jinggangmycin A 2% · Bacillus cereus 1×108 CFU/g AS,20% Jinggangmycin · Prochloraz WP) reached over 81.64%,while of 60% Pyraclostrobino · Metiram WG and 0.5% amino Oligosaccharins AS were not so that good.The 8 kinds of fungicide could increase yield of rice at different degrees,ranging from 3.84% to 8.88%. |
