Comments

Reduce the risk of resistance by spraying only where red stele has been observed.

Ridomil Gold: Make one application in early September and a second treatment in late October but no later than October 31. Apply in sufficient water (2,500 L/ha) to ensure movement into the root zone.

Aliette: Make up to four applications per season, two in spring and two in fall. Apply as a foliar spray in spring when plants start active growth. Apply at 30-60 day intervals. Make fall applications when soil conditions favour disease development (e.g., high soil moisture, cool temperatures).
