Caused By Agent Kind

Connects a crop pest or disease to the concept naming the kind of organism or agent that causes it, such as a fungus, a bacterium, a virus, a nematode, an insect, a mite, a parasite or a prion. The inverse reading, Agent Kind Of, names the same link from the agent kind toward each pest or disease grouped under it. This relation gives the agent kind already recorded as an enum fact on each pest or disease a durable entity identity; it does not replace that enum fact, which keeps classifying every pest or disease exactly as before, and the compound label Insect or Mite is linked to both of its named components.
