Growers have limited options when it comes to controlling plant growth to induce lateral branching, to insure uniform height and to control crop timing. Traditional strategies have involved manual pinching or trimming and/or applying plant growth regulators. When choosing a growth control strategy, growers need to consider the following issues: Cost. Manual pinching is labor intensive. Growth regulators have labor and product costs associated with their application. Speed. Manual pinching is a slow,time-consuming process. Pinching a large crop can often take days and may require several employees. Although growth regulator applications are faster, there is still the time involved with preparation and clean up as well as the application time itself.
