(Agricultural Wealth Network) Cultivating short, sturdy, and strong seedlings for overwintering is the foundation for high rapeseed yields. Paclobutrazol and uniconazole are broad-spectrum plant growth regulators. Using paclobutrazol or uniconazole to cultivate strong seedlings can enhance stress resistance and is an indispensable key technique. The methods for using paclobutrazol and uniconazole are: in mid-December, when direct-seeded rapeseed reaches the 4-leaf stage, use 50 grams of 15% paclobutrazol wettable powder per mu, diluted in 50 liters of water for foliar spraying; alternatively, use 11 grams of 5% uniconazole wettable powder, diluted in 50 liters of water for foliar spraying.
