Disclaimer Regarding Disease Resistance: The term “resistance” is defined as a plant’s ability to resist, not necessarily prevent
disease. Resistance may be conferred by general plant health or by resistance genes. The use of resistance genes is a well documented method of conferring mildew resistance in lettuce. The use of resistant varieties, in conjunction with proper pesticide, fertilizer,
cultivation and irrigation practices, will go a long way to reducing or eliminating infection. However, various factors, such as stress and
pathogen populations, often lead to a resistant plant becoming infected.
Disclaimer Regarding Variety Descriptions and Illustrations: Descriptions and illustrations represent Shamrock Seed Company’s
products as grown in our trial fields in various locations. Performance and appearance may vary under different growing conditions and
in other geographical locations. It is advised to investigate whether differences may be expected in your growing regions.
Utility Patent: Many of Shamrock genetic lines are protected under U. S. Utility Patents. This Patent type allows for “specific use only” and
does not provide use for research or “grower exclusions”. Utility Patented varieties exclude all unauthorized seed usage and propagation.
