AVA-ASAJA tests anti-pollination nets to tackle seeds in citrus

AVA-ASAJA has launched a field trial at its Finca Sinyent experimental farm to assess anti-pollination nets as a possible tool against “pinyolà,” a long-running problem for Valencian citrus growers.

The issue is caused by cross-pollination between certain citrus varieties, which leads to seeds in fruit that is expected by the market to be seedless. This reduces commercial value and can directly affect farm profitability.

The trial is being carried out on varieties affected by seed formation, including Nadorcott, Leanri and Orri. The nets are designed with a special mesh that blocks bees from reaching the flowers, limiting the pollination that causes seeds to develop.

AVA-ASAJA is working with Castellón-based Servicios Agrícolas Meliá on the project. The nets have been installed both manually and with a mechanised system using a specific implement that places and removes the cover directly over the trees.

The association says the mechanised option could be key to lowering labour costs and making the system more practical for commercial farms. The mesh also allows plant protection treatments to reach the tree canopy.

AVA-ASAJA said the trial should provide objective data on the nets’ effectiveness, real costs and potential use in citrus orchards. The group also called for public aid to help growers adopt protective systems, especially in varieties more exposed to cross-pollination.
