How Does DA-6 Improve Crop Yield, Quality, and Stress Resistance?

Technical Introduction

Diethyl Aminoethyl Hexanoate (C₁₂H₂₅NO₂, CAS No. 10369-83-2), commonly known as DA-6, is a broad-spectrum plant growth regulator with auxin-like activity.
It enhances photosynthesis, protein synthesis, and nutrient absorption, leading to improved plant vigor, yield, and quality.
DA-6 is soluble in most organic solvents and partially soluble in water when emulsified, making it versatile for various agricultural formulations.

Applications

1. Field Crops

• Yield Increase: Boosts grain weight and total production in rice, wheat, corn, and soybeans.

• Root Growth: Strengthens root systems for better nutrient and water uptake.

2. Horticultural Crops

• Fruit Enlargement: Improves fruit size, sweetness, and color in melons, citrus, grapes, and berries.

• Flowering Regulation: Promotes bud differentiation and increases flowering rate.

3. Stress Resistance

• Drought & Salinity Tolerance: Enhances water retention and osmotic adjustment.

• Cold & Heat Resistance: Improves enzymatic activity under temperature extremes.

Advantages

• Multi-Functionality: Works as a growth promoter, yield enhancer, and stress reliever.

• Low Dosage Requirement: Effective in ppm concentration range.

• Wide Compatibility: Can be mixed with fertilizers and most pesticides.

• Environmentally Friendly: Biodegrades naturally with low toxicity.

Typical Parameters

FAQs

Q1: Is DA-6 safe for all crops?
A1: Yes, when applied at recommended doses; excessive use can cause abnormal growth.

Q2: How is DA-6 usually applied?
A2: Through foliar sprays, seed soaking, or root irrigation.

Q3: Can DA-6 be used with GA₃ or CPPU?
A3: Yes—synergistic effects are often observed when combined with other PGRs.

Q4: Does DA-6 improve crop quality as well as yield?
A4: Yes, it enhances sugar content, vitamin levels, and appearance in many fruits.

Q5: How quickly does DA-6 work?
A5: Visible effects such as increased vigor may appear within 3–7 days after application.
