What conditions would render plants non-kosher?

Question

Under certain conditions, I know that uncontaminated (e.g. no insects / meat, etc) plant-based foods are prohibited (ie., non-kosher). Examples I can think of include:

1. Non-kosher wine

2. Chometz during Pesach and

3. Plants harvested on the sabbatical/shmita year

What other conditions would render uncontaminated plant-based foods non-kosher?
