In order to enhance fruit yield and quality, reduce the frequency of pesticide sprays, and extend the lifespan of fruit trees, it's essential to focus on key periods for pest and disease control. By following a well-timed spraying schedule, you can effectively manage pests and diseases while minimizing chemical use.
First, during the bud enlargement stage—often referred to as the "light rod period"—it's crucial to apply high-concentration fungicides combined with insecticides. This should be done thoroughly, covering both the canopy and the base of the tree. This step helps control overwintering pathogens and pests that may have survived the cold season.
Next, during the flower bud stage, a higher concentration of fungicides along with insecticides should be sprayed to prevent flower rot, which can significantly impact fruit set and quality.
One week after flowering, another round of spraying is recommended. At this point, the focus shifts to preventing various fungal diseases as well as pests like aphids, red spiders, and pear hibiscus. This timing is critical to protect the young fruits from early infestations.
After harvest, it's important to spray a concentrated solution of bactericides and insecticides before the leaves fall. This helps eliminate any remaining pests and reduces the risk of re-infestation in the following growing season. When mixing sprays, always ensure compatibility between products—avoid mixing alkaline and slightly acidic formulations, as this can reduce effectiveness or even damage the plants.
By carefully managing these key stages, growers can achieve healthier trees, better yields, and more sustainable farming practices.
