inorganic fungicide: A fungicide made from inorganic substances such as sulfur. Helps farmers manage fungal diseases in crops.

inbreeding: The process of mating or crossing between closely related individuals, leading to a reduction in variation. Compare outbreeding. Helps farmers manage genetic diversity in livestock.

immunisation: The production of immunity to a specific disease, either by injecting an antiserum or by giving an individual the disease in such a small dose that the body does not develop the disease, but produces antibodies to counteract it. Helps farmers protect livestock from diseases.

ICA: International Coffee Agreement – an agreement between countries to stabilize the price of coffee. Helps coffee farmers by providing market stability.

inbreeding depression: A reduction in variation and vigor arising in a population that is repeatedly inbred. Compare heterosis. Helps farmers recognize and avoid negative effects of inbreeding.
