IMMUNE
Not subject to damage or injury from attack by a particular disease causing organism or virus by a particular insect or for certain conditions of soil or climate.

RESISTANT
Capable to some degree of enduring an attack by a particular insect or disease causing agent, or able to withstand certain adverse conditions of growth. Resistant or slightly susceptible varieties may be expected to survive all but the most severe infestation or other specified adverse conditions, though yield and quality may be somewhat affected.

SUSCEPTIBLE
Easily subjected to injury or damage from attack by a particular disease causing organism or a particular insect or even from adverse soil or climate conditions.

TOLERANT
Moderately susceptible varieties may be expected to survive and produce an exceptable crop under moderately adverse conditions, but they also may be expected to become affected if conditions that are highly favorable to the disease or insect continue for a long period. A Tolerant variety is usually easier to protect from damage by a particular disease, insect or adverse condition than a Susceptible variety.

TREATED
Some of the seeds we carry are coated with a fungicide, insecticide or both to protect seed during storage. Seed will be clearly marked if treated. The treated seed should never be used for edible seed purposes. Seed treatments do not effect the plant that grows from seed.
