In double-cropping rice regions, tight cultivation schedules often lead to excessive height in late-season rice seedlings. This can cause seedling failure after transplanting, which not only hinders nutrient accumulation but also severely reduces the number of productive panicles and filled grains,

Usage methods and dosages for DA-6 vary significantly depending on the crop. Failure to observe these details or using incorrect dosages can result in adverse effects rather than the intended benefits.

Drought stress in spring crops can be mitigated through a comprehensive suite of measures, including scientific irrigation, moisture-conserving mulching, rational fertilization, and the application of plant growth regulators. Among these, the use of plant growth regulators stands as one of the key technical means for enhancing a crop's inherent drought resistance.

The plant growth regulators recommended for use during the growth cycle of rapeseed (canola) primarily include Paclobutrazol (Paclo), Uniconazole, Brassinolide, and DCPTA. Their core functions are to control excessive vegetative growth, prevent lodging, promote branching, enhance stress resistance, and significantly boost yield.
