Plant Growth Regulators for Wheat: Boost Yield, Prevent Lodging, Enhance Quality

Strategic PGR use in wheat optimizes growth, increases grain weight, and raises yields.

Key Regulators & Timing

• Cycocel (early jointing): 0.15–0.3% solution, 50–75 kg/acre. Dwarfs plants, strengthens stems, prevents lodging. Tank-mix with 2,4-D for broadleaf weeds.
• Mepiquat (jointing): 15–20 ml/acre in 50–60 kg water. Reduces lodging, +10–20% yield.
• Petroleum fueling agent (flowering–grain fill): 1000x dilution, 50 kg/acre. Heat defense, +7.8% yield.
• NAA (pre-grain fill): 40 mg/kg, 50 kg/acre. Promotes cell division, root formation, fruit set.
• Fulvic Acid (booting): 50 g in 2.5–10 kg water/acre. Drought resistance, +16.6% yield.
• Gibberellin (jointing): 40 mg/kg, 40–50 kg/acre. More grains, heavier grains.
• Uniconazole (1 wk pre-jointing): 30–40 mg/kg, 50 kg/acre. Prevents lodging under high density/fertility, +15.4% yield.
• Plant cytokinin (jointing/heading): 50 g in 200–300 kg water. Chlorophyll/protein boost, photosynthesis, early maturity.
• Phenoxyacetic acid (grain fill): 60 mg/kg, 25 kg/acre. Heat defense, heavier grain.
