Experts from INIA Quilamapu have warned that increased rainfall in the spring could lead to an increase in diseases affecting European hazelnut trees, such as the European hazel blight caused by the bacteria Xanthomonas corylina. These infections can cause significant losses in fruit production if not controlled in a timely manner, with some cases resulting in up to a 50% decrease. INIA is hosting a workshop to promote the use of biological control technology, specifically endophytic fungi, to counteract the presence and damage caused by the bacteria.

“We are in for a complicated spring due to the increase in rainfall estimated by specialists,” said INIA Quilamapu nut fruit expert Asdrúbal Rodríguez, who added that conditions are being generated that are conducive to an increase in the presence of diseases. Among them, the European hazel blight stood out, caused by the bacteria Xanthomonas corylina, which is characterized by generating lesions in the bud, shoots and leaves of the tree. “The first infections appear in the buds, which could affect sprouting and subsequent fruit production, so if it is not controlled in a timely manner, losses close to, in extreme cases, up to 50% of the production, figures that could increase. in more susceptible varieties like Barcelona,” Rodríguez emphasized. The INIA specialist indicated that the problem worsens in those orchards that are poorly managed, especially in their establishment, irrigation and nutrition.
