To reduce pests and diseases in pears, minimize pesticide use, and improve the fruit's appearance, proper bagging is essential. Here are seven key points to consider when bagging pears:
1. Throughout the entire bagging process, avoid touching the young fruit with your hands to prevent accidental peeling of the skin.
2. When tying the elastic band, be careful not to apply too much pressure. Excessive force can damage the fruit stem or cause the wire to become too tight, which may hinder fruit growth. On the other hand, if it's too loose, the fruit might fall off during windy conditions.
3. The top of the bag should not be tied like a bell mouth. This could allow rainwater or pesticides to enter the bag, and also prevent leaves from being accidentally placed inside.
4. During the bagging process, make sure the ventilation and drainage holes are open, and position the fruit in the center of the bag for optimal air circulation and protection.
5. If there has been recent rainfall or if pesticide spraying hasn't fully dried, wait at least 5 days before bagging. This helps avoid issues such as black spots or fruit rust on the surface.
6. Do not bag the fruit if there is still dew or moisture on the surface. Bagging while wet can lead to fungal infections and unsightly blemishes on the fruit.
7. Choose healthy, moderately vigorous trees for bagging during the fruiting period. Avoid using old, weak, diseased, or small, aging trees, as they may not produce high-quality fruit.
By following these guidelines, you can significantly enhance the quality and safety of your pear harvest while protecting the fruit from pests and environmental damage. This method not only improves the visual appeal of the fruit but also supports more sustainable farming practices.
