In order to enhance fruit yield and quality, minimize pesticide application, and extend the growth period of trees, it's essential to focus on key periods for pest and disease management. Here are the critical times to apply treatments effectively:
1. When buds begin to swell significantly, this is known as the "light rod medicine" stage. At this time, it's recommended to spray a high concentration of fungicides and insecticides both on the tree and around its base. This helps control various overwintering pathogens and pests that may threaten the crop.
2. During the flower bud stage, applying a higher concentration of fungicide combined with insecticide is crucial. This helps prevent flower rot and ensures healthy blossoms, which are essential for good fruit set.
3. One week after the flowers fall, it's important to spray again with a mixture of fungicides and insecticides. This stage is critical for preventing diseases such as powdery mildew, as well as controlling pests like aphids, spider mites, and pear hibiscus, which can damage the young fruit and leaves.
4. After harvesting the fruit, it's advisable to spray a stronger concentration of fungicides and insecticides before the leaves fall. This step helps eliminate overwintering pests and reduces potential damage in the following growing season. When mixing pesticides, always be cautious—some alkaline and acidic formulations should not be combined, as this could reduce their effectiveness or even harm the plants.
By following these key stages, growers can manage pests and diseases more efficiently, leading to healthier trees and better-quality fruit. For more information, visit Pesticide Network. Please cite the source when using this content.
