Other claims from this paper (11)
- Intervention effect Silicon lowered BPH egg-laying relative to untreated controls under all silicon treatments, regardless of nitrogen or variety, in a choice experiment.
- Intervention effect In a no-choice experiment, silicon reduced egg-laying on the susceptible rice variety.
- Intervention effect In a no-choice experiment, silicon did not reduce egg-laying on the resistant rice variety carrying the BPH32 gene.
- Mechanism Silicon mainly enhanced antixenosis defenses of rice, as suggested by the stronger effects in choice experiments.
- Intervention effect Silicon had no effect on whitebacked planthopper (WBPH) or green leafhopper (GLH) in rice.
- Intervention effect Silicon reduced blast damage to both susceptible and resistant rice carrying the Piz, Piz-5 and Pi9 genes.
- Intervention effect Silicon reduced damage from a virulent strain of bacterial blight in susceptible and resistant rice carrying Xa4, Xa7 and Xa4 + Xa7.
- Intervention effect Silicon had little effect on damage from a less virulent strain of bacterial blight in susceptible and resistant rice.
- Intervention effect When combined with host resistance, silicon had an additive effect in reducing biomass losses of rice infested with bacterial blight, with silicon contributing 20%.
- Intervention effect Host resistance alone reduced biomass losses of rice infested with bacterial blight by up to 50%.
- Recommendation Silicon-containing soil amendments combined with host resistance may reduce biotic stresses in rice.
