1. Cultivation of Strong Rice Seedlings: The best application period for rice is 5-7 days after sowing during the one-leaf-one-heart stage. The appropriate dosage is 3 kg of 15% Paclobutrazol wettable powder per hectare mixed with 1500 kg of water (i.e., 200 g of Paclobutrazol per mu, mixed with 100 kg of water). Drain the seedling field and spray uniformly on the seedlings, using a solution concentration of 500 times (300 ppm) Paclobutrazol. After application, the elongation rate of the plants slows down, achieving the effects of controlling growth, promoting tillering, preventing seedling loss, and strengthening seedlings.
2. Preventing Lodging in Rice: During the jointing stage of rice (30 days before heading), spray 1.8 kg of 15% Paclobutrazol wettable powder per hectare mixed with 900 kg of water (300 ppm) evenly on the rice stems and leaves. This treatment can reduce the height of rice plants by nearly one-third and effectively prevent lodging.
3. Cultivation of Strong Rapeseed Seedlings: At the three-leaf stage of rapeseed seedlings, use 600-1200 g of 15% Paclobutrazol wettable powder per hectare mixed with 900 kg of water (i.e., 100-200 ppm) to spray the solution on the stems and leaves of rapeseed seedlings. This promotes chlorophyll synthesis, increases photosynthesis rate, results in shorter and more leafy rapeseed plants, reduces sclerotinia disease, enhances stress resistance, and increases pods and yield.
4. Preventing Excessive Growth in Soybeans: During the initial flowering stage of soybeans, use 600-1200 g of 15% Paclobutrazol wettable powder per hectare mixed with 900 kg of water (i.e., 100-200 ppm) to spray the solution on the stems and leaves of soybean seedlings. This controls growth and increases pods and yield.5. Controlling Growth in Wheat: Use an appropriate depth of Paclobutrazol to treat seeds. It enhances the seedling strength, promotes tillering, reduces height to prevent lodging and increase yield. Mixing 20 g of 15% Paclobutrazol wettable powder with 50 kg of wheat seeds (i.e., 60 ppm) can result in a 5% reduction in plant height. It is suitable for early-sown wheat fields planted at a depth of 2-3 cm, and should be used under conditions of good seed quality, land preparation, and moisture...
