What is the usage of 2-4d plant growth regulator?
Usage of 2-4d plant growth regulator:
1. Tomato:
From 1 day before flowering to 1-2 days after flowering, use 5-10mg/L 2,4-D solution to spray, apply or soak the flower clusters to prevent falling flowers and fruits.
2. Eggplant:
When 2-3 flowers are open on the plant, use 2.5mg/L 2,4-D solution to spray on the flower clusters to increase the fruit setting rate.
3. Winter melon:
When the winter melon blooms, use 15-20mg/L 2,4-D solution to apply to the flower stalk, which can significantly increase the fruit setting rate.
4. Zucchini:
When the flowers are half-opened or just opened, use 10-20mg/L 2,4-D solution to apply to the zucchini flower stalk to prevent falling flowers and increase yield.
5. Citrus and grapefruit:
After the citrus blooms or when the green fruits are about to mature and change color, spraying the citrus fruits with a 24 mg/L 2,4-D solution can reduce fruit drop by 50-60% and increase the number of large fruits. Treating the harvested citrus with a mixture of a 200 mg/L 2,4-D solution and 2% limonol can extend the shelf life.
