Other claims from this paper (4)
- Intervention effect A 6% kaolin particle film pretreatment decreased the downy mildew disease index by 30% relative to untreated vines.
- Intervention effect KPF treatment reduced hydrogen peroxide and malondialdehyde concentrations in grapevine leaves, mitigating oxidative damage from P. viticola.
- Mechanism The protective effect of KPF may be due to increased antioxidant enzyme activity and antioxidant metabolites.
- Intervention effect KPF treatment increased disease resistance enzyme activity and expression of related genes in grapevine.
