Other claims from this paper (11)
- Intervention effect Pretreatment with novochizol at 0.125% four days before infection gave a stable reaction of wheat to stem rust.
- Intervention effect Pretreatment with novochizol at 0.125% decreased the number of stem rust pustules on wheat.
- Intervention effect Novochizol-pretreated infected wheat had lower catalase activity than infected plants without novochizol at both stages.
- Intervention effect Novochizol-pretreated infected wheat had lower peroxidase activity than infected plants without novochizol from 10 to 144 h after inoculation.
- Intervention effect Novochizol-treated infected wheat showed an increase in phenolic compound concentration.
- Intervention effect In novochizol-pretreated infected wheat, an early stage up to 10 h after inoculation was characterized by antioxidant activity.
- Intervention effect In novochizol-pretreated infected wheat, a late stage from 10 to 244 h after inoculation was characterized by prooxidant activity.
- Association The first peak of reactive oxygen species in infected wheat is associated with superoxide anion accumulation.
- Mechanism Hydrogen peroxide has a protective function that leads to the death of pathogen mycelial cells.
- Mechanism Novochizol pretreatment is suggested to contribute to enhanced wheat defence functions against stem rust.
- Recommendation Novochizol shows promise and safety as a biological plant protection product at a very low effective dose.
