Propyl Dihydrojasmonate

Propyl Dihydrojasmonate

Propyl dihydrojasmonate (PDJ) is a synthetic jasmonic acid derivative used to improve fruit color and quality. Compared to other jasmonates like MeJA, PDJ has better chemical stability, longer-lasting effects in plants, and easier absorbability.

PDJ is applied during apple and grape production to stimulate anthocyanin accumulation, enhancing the red pigments in fruit skin for better color development.

Dora Agritech specializes in supplying PDJ technical grade products and formulations for over 5 years, focused on apple and grape color enhancement applications. With extensive experience in this field, Dora Agritech is an ideal partner for fruit growers looking to improve color and quality using PDJ.

1. PDJ is a derivative of jasmonic acid with similar structure and functions. It mimics the plant hormone to regulate growth like natural jasmonates.

2. As a stress resistance substance, PDJ can spread rapidly in plants and promote synthesis of ethylene, abscisic acid and anthocyanins.

3. It stimulates carotene synthesis and enhances antioxidant capacity of fruits.

4. PDJ shortens fruit ripening period, increases stress response, nutrient absorption and accumulation of sugars and pigments.

5. When applied exogenously, PDJ provides analogue of jasmonic acid to catalyze color development, ripening and overall fruit quality.

1. Start applying PDJ after fruit swelling, repeat spray 7-14 days later to accelerate coloring by 10-14 days.

2. When 10-20% coloring exceeded, double PDJ dose, repeat spray to advance color change.

3. If >50-60% coloring achieved, spray directly on fruits to complete color change in 4 days.

4. Best to spray before 8am or after 5pm, morning applications are more effective.

5. Avoid using during severe disease outbreaks, treat crops first before applying.

6. PDJ works best with plenty of sunlight.
