Uses and Application of Prohexadione Calcium in Grapes
Prohexadione calcium is a highly active plant growth regulator that can be used to control the growth and development of many crops and is frequently used in agricultural production.
Effects of Prohexadione Calcium
Prevents lodging: Prohexadione calcium can shorten stem elongation, control internode growth, make stems stronger, and dwarf the plants, thus preventing lodging.
Promotes growth and increases yield: Prohexadione calcium can promote root growth, improve root vitality, increase leaf chlorophyll content, promote lateral bud growth and root development, and improve plant resistance and yield.
Enhances disease resistance: Prohexadione calcium can enhance plant disease resistance, reduce damage to crops from diseases, and has a certain effect in controlling diseases such as rice blast and wheat scab.
Application of Prohexadione Calcium
Although the specific application method may need to be adjusted according to actual conditions, the application methods for other crops can be used as a reference. For example, during the tillering stage of wheat, use 50-75 grams of 5% Prohexadione calcium effervescent granules per mu, diluted in 30 kg of water for even spraying; during the late tillering stage of rice or 7-10 days before jointing, use 20-30 grams of 5% Prohexadione calcium effervescent granules per mu, diluted in 30 kg of water for even spraying.
