The most common growth regulators used in greenhouse crop production are the plant growth retardants. Quality standards dictate that most container-grown greenhouse crops be compact, have short internodes, have a height consistent with the container they are grown in and have strong stems.rowth regulators may also be used to slow growth or hold plant material in the greenhouse. The growth retardants function by inhibiting gibberellin synthesis. If gibberellins are applied to a plant, it will become tall and spindly.
Weed killers, known also as herbicides, help control unwanted weeds, but the products use chemicals that can damage other plants that you want to keep.
