Photosystem 2 activity of Citrus volkameriana (L.) leaves as affected by Mn nutrition and irradiance
Citrus volkameriana (L.) plants were grown for 43 d in nutrient solutions containing 0, 2, 14, 98, or 686 µM Mn (Mn0, Mn2, Mn14, Mn98, and Mn686, respectively). To adequately investigate the combined effects of Mn nutrition and irradiance on photosystem 2 (PS2) activity, irradiance response curves for electron transport rate (ETR), nonphotochemical ...

Pest categorisation of ‘Blight and blight‐like’ diseases of citrus
Abstract The EFSA Panel on Plant Health performed a pest categorisation of ‘Blight and blight‐like’ for the EU territory. Blight is a major disease of citrus. Similar ‘blight‐like’ diseases are also known (e.g. declinio, declinamiento) and are addressed simultaneously with Blight in the present categorisation.

Pest categorisation of Hishimonus phycitis
Abstract The Panel on Plant Health performed a pest categorisation of Hishimonus phycitis (Hemiptera: Cicadellidae) for the EU. H. phycitis is a well‐defined species, occurring in tropical and subtropical Asian countries from Iran to Malaysia. H. phycitis is polyphagous. Hosts of particular relevance to the EU include Citrus spp. and Solanum melongena.
