Crete is entering a critical period in the battle against the olive fruit fly, with September expected to be decisive for protecting this year’s harvest.
As weather conditions continue to favor the spread of the pest, the Region of Crete says monitoring and spraying operations are proceeding across the island, with a second round of treatments nearing completion and a third already carried out in some northern areas.
“Now is the time to win the battle against the olive fruit fly,” Stavros Tzedakis, the Region of Crete’s Deputy Regional Governor for Agricultural Economy, told Cretalive.
The warning matters well beyond the island’s olive groves. Olive oil is one of Crete’s most important economic pillars after tourism, supporting farming households while feeding into the island’s restaurants, food businesses, exports and a range of products from cosmetics to traditional foods. A poor olive harvest therefore has consequences far beyond the producers themselves.
According to Tzedakis, recent weather conditions have encouraged olive fruit fly populations to increase, something also reflected in data from the region’s monitoring trap network.
Particularly vulnerable this year are large-fruited olive varieties, groves with low to moderate fruit production and irrigated plantations.
The Region says the necessary pesticides have now arrived and spraying is continuing. The second island-wide treatment is being completed, while some areas, particularly in northern Crete, have already received a third application. The coming weeks will be particularly important.
“There are currently significant olive fruit fly populations, but the response of the services is immediate,” Tzedakis said, pointing specifically to September, when climatic conditions are expected to become especially favorable for the pest.
Spraying dates and the areas covered are published by the Region of Crete through its olive fruit fly control program. There is another pest to watch this season as well.
Another Threat to Olive Crops
The olive weevil, or rynchites, is also causing concern. The insect feeds on young developing olives after fruit set and can contribute to fruit drop and lower oil content if it is not detected and addressed in time.
Tzedakis acknowledged concerns over fruit loss but remains broadly optimistic about this year’s harvest, at least in terms of quantity.
That makes the next few weeks particularly important. For Crete, protecting the olives is not simply about protecting a crop. It is about protecting one of the island’s economic foundations.
Cretalive reports that the region’s response is already underway, but with September approaching, the real test may be just beginning.
