- ... The abundance and spatial dispersion of Diaphorina citri Kuwayama (Hemiptera: Psyllidae) were studied in 34 grapefruit (Citrus paradisi Macfad.) and six sweet orange [Citrus sinensis (L.) Osbeck] orchards from March to August 2006 when the pest is more abundant in southern Texas. Although flush shoot infestation levels did not vary with host plant species, densities of D. citri eggs, nymphs, and a ...

- ... Citrus tristeza virus (CTV) is one of the most devastating disease in areas where sweet orange or grapefruit are budded onto sour orange rootstock. In Texas, the citrus industry is located in the far south of the state in a high pH and calcareous soils region, which makes sour orange the best rootstock option. The Texas industry has been under a threat since the arrival in Florida and Mexico of th ...

- ... Fertilizer recommendations for citrus production on heavier textured, calcareous soils increase with the age of the tree up to 168kgNha⁻¹ year⁻¹ from a soluble source in one or two applications. Such practices may be inefficient and could cause detrimental effects on fruit quality. A variety of fertilization practices are used in South Texas, and additional evaluation is needed. Rates and sources ...
