Sunburn in avocado fruit is one of the main problems in high-radiation zones, causing commercial rejection, economic losses, and limiting the percentage of export-quality fruit. In states like Michoacan, where radiation conditions are intense during the fruiting stage, management alternatives are often limited.
A demonstration was conducted in a Hass avocado orchard in Michoacan, Mexico, comparing a biostimulant-treated plot against a control, evaluating percentage of affected fruits, severity of surface damage, and overall fruit quality during the fruiting stage under real high-radiation conditions. Results were consistent and clear: treated fruits showed evident reduction in surface damage compared to controls.
Specific biostimulation improves the physiological condition of the plant, promoting synthesis of protective compounds (waxes, carotenoids), photosynthetic efficiency, and better tolerance to intense radiation. Evidence from Michoacan confirms that specific biostimulation is an effective tool to reduce sunburn in Hass avocado, improve fruit quality, and increase producer profitability. In high-radiation scenarios, protecting crop physiology makes the difference between losing fruit or getting it to export.
