In order to enhance fruit yield and quality, minimize the use of **pesticides**, and extend the growth period of trees, it is essential to focus on key periods for pest and disease control. Proper timing of pesticide application not only improves effectiveness but also reduces environmental impact and long-term damage to the orchard.
1. During the bud swelling stage, when buds begin to inflate, it is the ideal time to apply a high concentration of fungicides and insecticides. This period is critical for controlling overwintering pathogens and pests that have survived the cold season. Spraying should be done both on the tree and under the canopy to ensure full coverage.
2. During the flower bud stage, a higher concentration of fungicides combined with insecticides should be applied. This is especially important for preventing blossom blight and other early-season diseases that can severely affect fruit development.
3. One week after the flowers fall, another round of spraying is recommended. At this point, the focus shifts to preventing various fungal infections and controlling pests such as aphids, spider mites, and pear hibiscus. Early intervention helps avoid widespread infestations later in the season.
4. After harvesting the fruit, it's crucial to spray a stronger solution of fungicides and insecticides before the leaves fall. This step aims to eliminate any remaining pests that could overwinter and cause problems in the following year. When mixing chemicals, always check compatibility—never mix alkaline and acidic products together, as this can reduce effectiveness or even damage the plants.
By following these four key stages, growers can significantly improve their pest management strategy, leading to healthier trees, better fruit quality, and more sustainable farming practices.
