Diethyl aminoethyl hexanoate DA-6 is a plant growth regulator primarily used to promote crop growth, increase yield, and improve quality. The following describes its specific application methods for potatoes, sweet potatoes, and ginger during their tuber expansion phase.
Application in Potatoes
During the tuber expansion phase, it is recommended to spray 8% soluble powder at a dilution of 1000-1500 times, or dilute it 600-800 times for root irrigation. This promotes root development, accelerates tuber expansion, and enhances disease and stress resistance.
Application in Sweet Potatoes
For sweet potato cultivation, it is recommended to use a rooting and enlargement agent (containing DA-6) via foliar spray (diluted 800-1200 times) or root irrigation (diluted 600-800 times) to promote tuber development and improve yield and quality.
Applications for Ginger
During the ginger expansion phase, spray a 10-20 mg/L solution of diethyl aminoethyl hexanoate DA-6. Combined with potassium nitrate, this solution accelerates fruit expansion and improves photosynthetic efficiency. However, be sure to switch to potassium sulfate after veraison.
Precautions:
Avoid mixing DA-6 with alkaline pesticides or fertilizers to prevent its effectiveness.
It remains active at low temperatures (<20°C), making it suitable for greenhouses and winter crops.
The concentration may need to be adjusted for different crops. For example, a higher concentration (10 mg/L or higher) is recommended for ginger to enhance its effectiveness.
