Herbs

Herbs Cilantro Marino Marino is reliable and thickly feathered with fine stalked leaves and improved bolting tolerance, High yielding and very aromatic. Dill Marino Ella Ella is an attractive dark green dill variety bred for pot and babyleaf production. Short hypotocyls give it a sturdy upright and compact plant habit. Green Sleeves Green Sleeves is suited for year round growing in open field and greenhouse production. Excellent growth in extreme hot conditions. Teddy Teddy is a compact dill variety with short hypocotyls. Excellent for potted herb production and open field due to its short plant habit, leaf pattern rotating the stem and bright spring green color. Also fits well in a clamshell due to leaf length.

Resistances Resistances in varieties of our crops will be coded (please, see our coding list on www.enzazaden.com for explanation), unless indicated otherwise. Varieties claiming the same level of resistance against a specific pest or pathogen may exhibit a different resistance response due to a different genetic makeup of a variety.It is to be noted that if a resistance is claimed in a plant variety it is limited to the specified biotypes, pathotypes, races or strains of the pest or pathogen. If no biotypes, pathotypes, races or strains are specified in the resistance claim for the variety, it is because no generally accepted classification of the cited pest by biotype, pathotype, race or strain exists. In this case resistance is only claimed against certain not further specified isolates of that pathogen. New biotypes, pathotypes, races or strains that may emerge are not covered by the original resistance claim. Immunity: not subject to attack or infection by a specified pest or pathogen Resistance: the ability of a plant variety to restrict the growth and development of a specified pest or pathogen and/or the damage they cause when compared to susceptible plant varieties under similar environmental conditions and pest or pathogen pressure. Resistant varieties may exhibit some disease symptoms or damage under heavy pest or pathogen pressure. Two levels of resistance are defined: • High resistance (HR): plant varieties that highly restrict the growth and development of the specified pest or pathogen under normal pest orpathogen pressure when compared to susceptible varieties. These plant varieties may, however, exhibit some symptoms or damage under heavy pest or pathogen pressure. • Intermediate resistance (IR): plant varieties that restrict the growth and development of the specified pest or pathogen, but may exhibit a greater range of symptoms or damage compared to highly resistant varieties. Intermediate resistant plant varieties will still show less severe symptoms or damage than susceptible plant varieties when grown under similar environmental conditions and/or pest or pathogen pressure. Susceptibility: the inability of a plant variety to restrict the growth and development of a specified pest or pathogen. Tolerance: the ability of a plant variety to endure abiotic stress without serious consequences for growth, appearance and yield. Vegetable companies will continue to use tolerance for abiotic stress.
