Sunshine Rose Seedless Treatment Formula

1. Sunshine Rose Seedless Treatment Formula

The formula for the seedless treatment of Sunshine Rose is mainly 20 mg/L of gibberellic acid and 3 mg/L of chlorfenapyr. The core of the Sunshine Rose will be formed more than 24 hours after the flowering. When it exceeds 72 hours, the core will be fully developed. It is more difficult to remove the core at this time. When processing the Sunshine Rose seedless, you can choose the period when the core is formed but not fully developed, that is, between 24-72 hours after the flowering.

2. Precautions for seedless processing of Sunshine Rose

Apply sufficient fertilizer: The seedless treatment requires the use of gibberellic acid. The premise of using gibberellic acid is to apply sufficient fertilizer. Therefore, before the seedless treatment, management should be strengthened, stronger tree vigor should be cultivated, and the application of organic fertilizer, mineral fertilizer, and trace element fertilizer should be strengthened. Foliar fertilizer should also be sprayed, which is beneficial to enlarge the leaves, enhance the tree vigor, and better carry out the seedless treatment.

Water enough before flowering: Ensure sufficient moisture before flowering, then expose the ground to the sun to increase the ground temperature, and then deal with the seedless situation after the ground temperature recovers.

Pruning the clusters in advance: You can prune the Sunshine Rose in advance, remove the clusters that are not growing well, reduce nutrient consumption, and promote the development of the remaining clusters.

Prevent sunburn: After processing, be sure to prevent sunburn to prevent the grapes from being sunburned.

Concentration control: When using the formula for treatment, if you encounter low temperatures, you can increase the concentration of the formula. Continuous low temperatures can be treated in advance. For trees with weaker vigor, the concentration can be reduced.

Time selection: When carrying out seedless treatment, you can wait until the dew disappears and avoid high temperature periods.
