The key to applying plant growth regulators lies in aligning them with the crop's critical growth stages. The goal is to precisely control excessive vegetative growth, preserve flowers and fruit, and promote ripening and yield—all without disrupting the plant's natural growth rhythm.

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.

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.
