Conium maculatum disturbed ground. It is used as a food plant by the larvae of some Lepidoptera species, including silver-ground carpet. The poison hemlock moth ("Agonopterix alstroemeriana") feeds on the plant during its larval stage. "A. alstroemeriana" has been widely used as a biological control agent for "C. maculatum". Poison hemlock flourishes in the spring, when most other forage is gone. All plant parts are poisonous, but once the plant is dried, the poison is greatly reduced, although not gone completely. The plant is poisonous to animals that graze on it. "Conium" contains the piperidine alkaloids coniine, N-methylconiine, conhydrine, pseudoconhydrine and gamma-coniceine
Beta (plant) with the highest economical value in the order Caryophyllales. Therefore, the members of "Beta" and the related genus "Patellifolia" are interesting as Crop wild relatives. Beta (plant) Beta is a genus in the flowering plant family Amaranthaceae. The best known member is the common beet, "Beta vulgaris", but several other species are recognised. Almost all have common names containing the word "beet". Wild "Beta" species can be found throughout the Atlantic coast of Europe, the Mediterranean coastline, the Near East, and parts of Asia including India. This genus consists of annual, biennial, or perennial species, often with fleshy, thickened roots.
