* Maintain stable soil moisture, avoiding alternating periods of drought with excessive or very heavy watering.

* Provide regular watering adapted to the plant's needs, especially during flowering, fruit set, and rapid fruit growth.

* Prevent plants from suffering water stress during periods of peak fruit growth.

* Improve drainage when water accumulates in the soil, as waterlogging can damage roots and reduce their absorption capacity.

* Also avoid excessively rapid drainage that leads to highly irregular water availability around the roots.

* Check the soil calcium content when the problem recurs.

* Maintain a suitable soil pH to promote calcium availability and proper root system function.

* Avoid excessive fertilizer applications that can increase soil salinity and hinder water and nutrient absorption. * Avoid significant imbalances between calcium and other cations such as potassium, magnesium, or ammonium, especially when intensive fertilization is carried out.

* Maintain a healthy and active root system, avoiding root damage during cultivation, transplanting, or work around the plant.

* Use organic matter and improve soil structure when necessary to promote adequate water retention and good root activity.

* Avoid excessive pruning or situations that drastically alter the ratio between leaf area and fruit load.

* Avoid excessively rapid vegetative growth caused by high nitrogen applications, especially during fruit development.

* Maintain balanced nutrition throughout the entire cycle, avoiding correcting the problem solely with one-off calcium applications.

* Apply calcium fertilizers to the soil when an analysis indicates insufficient calcium availability and the soil pH and conditions are compatible with their use. * In susceptible crops, consider foliar applications of calcium as a complementary measure, bearing in mind that their effectiveness in correcting blossom-end rot may be limited because calcium applied to the leaves does not always effectively reach the internal tissues of the fruit.

* Prioritize stable irrigation and proper root function over isolated foliar treatments.

* Remove severely affected fruit when necessary to prevent necrotic tissue from being colonized by secondary microorganisms.

* Avoid wounds and damage to affected fruit, as these can facilitate the entry of opportunistic fungi and bacteria.

* Conduct soil analysis and, when necessary, foliar analysis to determine if a nutritional deficiency actually exists before increasing fertilization rates.
