Selecting Suitable Plant Growth Regulators for Autumn Crops to Manage Growth and Enhance Stress Resistance
When using plant growth regulators on autumn crops, it is essential to consider both the specific growth characteristics of the crops and the environmental conditions typical of autumn—such as low temperatures, limited sunlight, and a tendency toward premature senescence.
Selecting the right regulator not only manages growth and boosts stress resistance but also ensures final yield and quality.
Suitable Plant Growth Regulators for Common Autumn Crops
Peanuts: To control excessive vegetative growth and prevent "leggy" stems, choose Prohexadione-calcium or Uniconazole; apply at the late flowering stage to shorten internodes and promote pegging. Combine with DA-6 to improve kernel fullness and prevent premature senescence in the later stages.
Corn: To control height and prevent lodging, choose a DA-6/Ethephon mixture or Chlormequat Chloride; apply at the 6–10 leaf stage to reduce plant height, strengthen stalks, promote root development, and improve wind resistance.
Solanaceous Vegetables (Tomatoes, Peppers, Eggplants): To promote fruit set during the flowering stage, choose Brassinolide, Sodium Nitrophenolate, or anti-drop agents (such as 4-CPA); apply during low-temperature periods to reduce flower and fruit drop and increase the fruit-setting rate.
Grapes: During the autumn color-change (veraison) period, choose S-Abscisic Acid or DA-6 to promote uniform fruit coloration, increase sugar content, and prevent uneven coloring.
Strawberries: To promote flower bud differentiation and earlier market availability, choose Gibberellins or Paclobutrazol; apply after transplanting to control excessive growth and encourage flowering, and combine with DA-6 during low-temperature periods to enhance cold resistance.
Winter Wheat: Treat seeds with Paclobutrazol before sowing and apply Chlormequat Chloride at the seedling stage to cultivate short, sturdy seedlings; this enhances cold and frost resistance and reduces freeze damage during overwintering.
Key Advantages of Using Plant Growth Regulators in Autumn
The activity of many regulators tends to decline in the low temperatures of autumn. DA-6 is one of the few varieties that maintains high activity in cold conditions; when used in combination with fertilizers or pesticides, it enhances their efficacy, alleviates phytotoxicity, and boosts the crop's ability to withstand cold and frost. Brassinolide enhances crop resilience against stressors such as cold, drought, and salinity/alkalinity. Suitable for virtually all autumn crops, it can significantly reduce growth damage caused by low-temperature stress when applied prior to a cold snap.
S-abscisic acid boosts crop vigor under adverse conditions—such as low temperatures and drought—and improves fruit set rates and quality; it is suitable for a wide range of crops, including autumn vegetables and fruit trees.
Selecting the right regulator not only manages growth and boosts stress resistance but also ensures final yield and quality.
