Alternaria leaf blight
Alternaria dauci
Every resistance code used across the Vira Agro catalogue, with the pathogen it refers to. Codes follow the abbreviations published by the International Seed Federation.
The variety highly restricts the growth and development of the pathogen under normal pest or pathogen pressure. Symptoms may still appear under very heavy pressure.
The variety restricts the pathogen, but may show more symptoms than a variety with high resistance. Losses are reduced rather than prevented.
Resistance describes how a plant behaves under defined test conditions. Local pressure, strain or race differences and growing practice all still apply — rotation, hygiene and monitoring remain necessary.
