Spain’s tomato growers to step up leaf miner controls
Weather conditions in Spain’s Almeria region are leading to a spread of tomato leaf miners (Tuta absoluta) particularly on the new spring-planted tomatoes. The authorities are promoting an integrated control model, including the predatory mirid bug, Nesidiocoris tenuis, as well as chemical products. Leaf miners hit the region some four years ago (Agrow No 589, p 25). Growers in Almeria have increasingly switched towards biological controls to protect their undercover vegetables for several years (Agrow No 643, p 10). This has included the use of controls against leaf miners.
