In my previous post we have been talking about Role of Pollinators in Pollination. Similarly petal fall stage is very important as this will make a base for quality fruit production
At the petal fall stage in
apples, several important tasks need to be carried out to support fruit
development, protect against pests and diseases, and promote overall tree
health. Here’s a breakdown:
🌸 1. Nutrient Management
- Apply Nitrogen (N): Moderate amounts for
healthy growth, avoid excess Nitrogen application to prevent poor fruit set.
- Calcium Sprays: Start foliar sprays of
calcium nitrate or calcium chloride to improve fruit firmness and prevent
disorders like bitter pit.
- Micronutrients: Apply boron, zinc, and other
essential micronutrients as needed, especially if deficiencies are noted.
🦟 2. Pest and Disease
Control
- Insecticides: Apply sprays to manage pests
like archips, fruit borers, aphids, and mites.
- Fungicides: Control diseases such as apple
scab, powdery mildew, Core rot. Use appropriate fungicides based on
regional guidelines.
✂️ 3. Thinning
- Start chemical thinning if required to
reduce fruit load and improve fruit size and quality. This is often done
shortly after petal fall.
💧 4. Irrigation
Management
- Ensure and maintain adequate soil moisture through proper irrigation,
especially if rainfall is insufficient.
📅 5. Weed Control
- Apply herbicides or mechanically remove weeds to
reduce competition for nutrients and water.
In our next post we must be discussing about important tasks in focus at pea stage of fruit development.
