Blossom End Rot in Oregon Spring Tomato Fruits
Definition: Blossom end rot is a physiological disorder that affects tomato fruits, particularly the Oregon Spring variety, causing a dark, sunken lesion at the blossom end. This condition is primarily caused by a calcium deficiency in the developing fruit, which leads to cell wall breakdown and subsequent tissue damage.Prevention of Blossom End Rot
1. Soil Preparation:Ensure that the soil is well-drained and has a pH level between 6.0 and 6.5, which is optimal for calcium uptake by the plants. Conduct a soil test to determine the nutrient levels and amend the soil accordingly with organic matter or lime if necessary.

2. Proper Watering:
Maintain consistent soil moisture levels by providing regular, deep watering to the tomato plants. Avoid overwatering, as it can lead to nutrient leaching and poor calcium uptake. Mulching around the plants can help retain moisture and regulate soil temperature.
3. Adequate Fertilization:
Apply a balanced fertilizer that includes calcium, such as calcium nitrate or calcium chloride, according to the recommended rates. This will help ensure sufficient calcium availability for the developing fruits. Avoid excessive nitrogen fertilization, as it can interfere with calcium uptake.
4. Proper Plant Spacing:
Provide adequate spacing between tomato plants to allow for good air circulation and reduce competition for nutrients. Crowded plants can lead to increased humidity levels, which may exacerbate blossom end rot.

5. Regular Monitoring:
Inspect the tomato plants regularly for any signs of blossom end rot. If you notice affected fruits, remove them promptly to prevent the spread of the disorder. Early detection and intervention can help minimize the impact of blossom end rot.
6. Calcium Foliar Spray:
In severe cases or as a preventive measure, you can apply a calcium foliar spray to the tomato plants. This can help supplement calcium levels and improve fruit development. Follow the manufacturer’s instructions for application rates and timing.
By following these preventive measures, you can minimize the occurrence of blossom end rot in Oregon Spring Tomato fruits and ensure a healthy harvest.
