    Use of the herbal fish poisons has been documented in a number of sources involving catching fish from fresh and sea water. [3] Tribal people historically used various plants for medicinal and food exploitation purposes. [4] Use of fish poisons is a very old practice in the history of humankind.

    It is possible to produce the hormone industrially using microorganisms. [2] Gibberellic acid is a simple gibberellin, a pentacyclic diterpene acid promoting growth and elongation of cells. It affects decomposition of plants and helps plants grow if used in small amounts, but eventually plants develop tolerance to it.

    4 interferes with Ca 2+ uptake and can be toxic to plants if used as a major nitrogen source. A 3:1 ratio of NO − 3-N to NH + 4-N (wt%) is sometimes recommended to balance pH during nitrogen absorption. [71] Plants respond differently depending on the form of nitrogen, e.g., ammonium has a positive charge, and thus, the plant expels one ...

    2,4-Dichlorophenoxyacetic acid is an organic compound with the chemical formula Cl 2 C 6 H 3 OCH 2 CO 2 H.It is usually referred to by its ISO common name 2,4-D. [4] It is a systemic herbicide that kills most broadleaf weeds by causing uncontrolled growth, but most grasses such as cereals, lawn turf, and grassland are relatively unaffected.

  8. Ethylene signaling pathway - Wikipedia

    en.wikipedia.org/wiki/Ethylene_signaling_pathway

    Ethylene chemical structure. Ethylene signaling pathway is a signal transduction in plant cells to regulate important growth and developmental processes. [1] [2] Acting as a plant hormone, the gas ethylene is responsible for promoting the germination of seeds, ripening of fruits, the opening of flowers, the abscission (or shedding) of leaves and stress responses. [3]

  9. Root rot - Wikipedia

    en.wikipedia.org/wiki/Root_rot

    To avoid root rot, it is best to only water plants when the soil becomes dry, and to put the plant in a well-drained pot. Using a dense potting media such as one dug up from outdoors can also cause root rot. Plants from different environments have different tolerances for soil moisture: plants evolved for desert conditions will experience root ...
