Other claims from this paper (9)
- Intervention effect In dual culture all four Trichoderma species significantly inhibited S. sclerotiorum mycelial growth by 60.1-63.1%.
- Intervention effect Volatile metabolites of the four Trichoderma species suppressed S. sclerotiorum mycelial growth by 90.3-94.1%.
- Intervention effect In field trials the Trichoderma combination significantly reduced white mold plant incidence and severity in 2021 and 2022.
- Intervention effect The Trichoderma combination lowered sclerotia production to 32.7 and 14.6 on ten plants in the two years.
- Intervention effect White mold incidence and severity on tubers were reduced to 1.6% and 0.4% in 2021 and 1.3% and 0.3% in 2022.
- Intervention effect Alternating Trichoderma with synthetic fungicides was statistically equivalent to Trichoderma alone in disease control.
- Intervention effect The fungicides-alone treatment was significantly less effective in disease control than the Trichoderma treatments.
- Intervention effect Potato yield was highest in plots treated with the Trichoderma combination (46.0 t/ha in 2021 and 52.9 t/ha in 2022).
- Recommendation The authors conclude that a mixture of the four Trichoderma species has potential as a cornerstone of sustainable disease management in Sinaloa.
