Preventive Measures

To prevent fruit drop in black sapote trees, it is important to take the following preventive measures:

Provide Optimal Growing Conditions: Ensure that the trees are planted in well-draining soil with adequate organic matter. Maintain proper irrigation and mulching to regulate soil moisture levels.

Implement Regular Fertilization: Conduct soil tests to identify nutrient deficiencies and apply appropriate fertilizers to meet the tree’s nutritional requirements.

Promote Pollination: Encourage pollinators, such as bees, by planting flowering plants nearby. Hand pollination can also be done by transferring pollen from male to female flowers using a small brush.

Monitor and Control Pests and Diseases: Regularly inspect the trees for signs of pest infestation or disease. Implement appropriate pest management strategies, such as using organic insecticides or fungicides, to prevent fruit drop.

Prune and Thin Fruits: Pruning the tree to improve air circulation and light penetration can help reduce fruit drop. Additionally, thinning excess fruits can prevent overcrowding and promote better fruit development.
