Other claims from this paper (15)
- Method / resource Fish powder was the best fermentation medium for Bacillus spp. Drt-11, giving 36.2×10~8 cfu/mL.
- Method / resource Peanut powder was the second-best fermentation medium, giving 19.6×10~8 cfu/mL.
- Method / resource The best fermentation conditions were 31-34 ℃, whisking at 180-200 r/min, pH 7.2-7.3 and oxygen rate 1∶1.
- Method / resource Under the best conditions, Bacillus spp. Drt-11 reached over 10^8 to 10^9 cfu/mL in fermented liquid.
- Association Longer time of sclerotia in the fermented liquid of Bacillus spp. Drt-11 was associated with a lower germination rate.
- Intervention effect Treating sclerotia for over 24 h in the fermented liquid reduced germination rate by 40-60%.
- Intervention effect Antagonism by Drt-11 reduced colony diameter to 13.9% of the control (CK).
- Intervention effect Antagonism by Drt-11 restrained the growth of hyphae.
- Intervention effect Antagonism by Drt-11 increased overground pure weight of rice by 5.17%.
- Intervention effect Antagonism by Drt-11 increased underground pure weight of rice by 25.0%.
- Intervention effect Antagonism by Drt-11 increased plant height of rice by 4.09%.
- Intervention effect Fermented liquid of Drt-11 maintained rice sheath blight control at about 80-85% in the fields, comparable to 20% Jinggangmeisu WP.
- Intervention effect Treatment with Drt-11 fermented liquid increased rice yields in a practical area test.
- Intervention effect Control effects of the three mixed rates were higher than with Drt-11 alone.
- Intervention effect Control effects of the three mixed rates were higher than with 20% Jinggangmeisu WP.
