In recent weeks, Morocco's agricultural industry has been hit by high temperatures. A severe heat wave, which has reached temperatures as high as 47 degrees Celsius in some regions, has raised alarm among producers seeking to implement various strategies to mitigate these effects and maintain the competitiveness of their products.

The berry industry has not been immune to this problem and has been working to maintain Morocco's sustained growth, which is considered a player with the potential to lead the global market. However, climate change and extreme conditions are challenges that producers must face.

The international researcher, Daniel Diaz, agricultural engineer and doctor in Plant Physiology of Fruit Trees in the Michigan State University, noted that one of the strategies to combat the effects of high temperatures is the use of bioregulators. Díaz participated in the month of July International Blueberries Seminar Trujillo 2025, held in Peru, where he addressed the topic of heat stress in blueberries and the use of bioregulators to combat this contingency.

Heat stress in blueberries: the Peruvian experience

“In 2023, there was an extreme heat wave in the region (Peru) that affected blueberries in particular. It was one of the first massive examples I saw of how climate change can affect an entire industry, and with a very specific effect. Within this framework, there are many tools we can use, such as bioregulators, to take care of nutrition, water, sanitation, etc.,” Díaz said in an interview for Blueberries Consulting.

Díaz emphasized that the use of bioregulators and hormonal compounds can help minimize the effects of high temperatures on crops, which requires thorough control. "For heat, the type of hormone used and how often is important to achieve a targeted, efficient, and consistent effect. But other aspects shouldn't be neglected either, because it's part of a comprehensive system," he maintained.

It should be noted that excessive heat can cause significant damage to plant and fruit development, resulting in dehydration, loss of firmness, and discoloration, which reduces the product's commercial quality.

Reducing heat stress in blueberries and berries

Dr. Daniel Díaz is a renowned researcher, professor and professional whose physiology specialty in the area of ​​plant hormones and its application in agriculture He has shared it extensively, pioneering the development of the commercial use of cytokinins in agriculture and the hormonal regulation of the root system in crops.

With important contributions to the design and formulation of innovative products based on hormonal bioregulators, author of the book Plant Physiology and technical reviewer of several specialty books, he has become one of the major references in the use of plant growth regulators and biostimulants for agriculture worldwide.

It is because of that Blueberries Consulting in the framework of 2025th International Seminar on Red Fruits, Morocco XNUMX will be participating with a presentation titled "Use of growth regulators to reduce heat stress in blueberries and berries." The event will be held on Wednesday, September 10, at the Royal Tulip City Center Hotel in Tangier.
