In order to enhance fruit yield and quality, reduce the frequency of pesticide applications, and extend the lifespan of fruit trees, it's essential to focus on key periods for pest and disease control. By adopting a strategic approach, farmers can effectively manage threats while minimizing chemical use. Here are the critical stages to consider:
1. **Bud Swelling Stage** – This is the time when buds begin to enlarge significantly, often referred to as the "light rod" period. At this stage, it's important to apply high-concentration fungicides combined with insecticides. Spraying should be thorough, covering both the canopy and the ground beneath the tree. This helps control overwintering pathogens and pests that may have survived the cold season.
2. **Flower Bud Stage** – During this phase, applying a higher concentration of fungicides along with insecticides is crucial. The primary goal is to prevent flower rot, which can severely impact fruit set and overall yield if left unchecked.
3. **Post-Flowering Period** – One week after flowering, it's recommended to spray again with a combination of fungicides and insecticides. This stage targets diseases that may develop after pollination, as well as common pests like aphids, red spiders, and pear hibiscus. Timely intervention at this point can prevent serious infestations later on.
4. **Pre-Leaf Fall Period** – After harvesting the fruits, a final application of bactericides and insecticides at a higher concentration should be done before leaves fall. This step is vital for eliminating any remaining pests that might overwinter in the tree or surrounding soil, reducing the risk of damage in the following growing season.
When mixing sprays, it's important to avoid combining alkaline and slightly acidic products, as this can reduce their effectiveness or even cause harmful reactions. Always follow label instructions and consider environmental factors such as temperature and humidity for optimal results. A well-timed and properly executed spraying schedule not only improves fruit quality but also supports long-term tree health and sustainability.
