Olive oil growers in Jaén have been advised to carefully examine the presence of the olive moth (Prays oleae) in their groves. Experts from the farmers association COAG have found evidence of a massive spreading that could be the most severe to date.See more: Olive Oil Production News
COAG Jaén asked its associates to seek the intervention of advisors in their groves. Such a considerable presence of the moth represents a major risk for the next harvest season’s olive yield.
Experts at COAG noted that traditional measures against the spreading of the moth have been hindered this year by the weather in many areas. Heavy rainfall hit the region when flowering was underway.
In the areas where no moth containment measures have been taken, the damage could spread to as much as 50 percent of the groves, COAG warned, while lesser damage of up to 20 or 30 percent could be expected in treated areas.
The group also noted that while temperatures have risen recently, the heat is not expected to reach 35°C (95°F) or higher that might kill off the eggs of the moth.
Quick action is imperative, the experts said, faced with what they say are unprecedented numbers of adult moths seen on the fields. They warn that without an aggressive response, many growers risk a large fruit drop come September.
