On the plantation of the Laszka variety of raspberries in Mazovia, where June was extremely hot, the plants were in a good condition thanks to irrigation.
When the first fruits were ripening mid-June, due to the favourable weather, the pressure of fungal diseases was smaller than if it had been raining regularly.
“But growers should stay vigilant because gray mold, raspberry rust and anthracnose are just waiting for more favorable conditions to develop,” says Dr. Kamil Jeziorek from Syngenta. “You don’t need intense rainfall, just a large varying temperatures, fog, and dew - in such conditions, fungal diseases can develop.”
