... Huanglongbing is a citrus disease that reduces yield, crop quality, and eventually causes tree mortality. The putative causal agent, Candidatus Liberibacter asiaticus (Rhizobiales: Rhizobiaceae), is vectored by the Asian citrus psyllid, Diaphorina citri Kuwayama. Disease management is largely through vector control, but the insect is developing pesticide resistance. A nonchemical approach to vecto ...

Abstract:
... Worldwide production and utilization of composts have dramatically increased over the past two decades, due to year-round ‘locally’ available feedstocks, more effective and economically viable production systems, continued improvement of commercial compost product(s) for specific horticultural industries, improved horticultural crop quality or yield, and advancements in ‘green’ technology that are ...

Abstract:
... BACKGROUND: Iron (Fe) chlorosis is a serious problem affecting the yield and quality of numerous crops and fruit trees cultivated in alkaline/calcareous soils. This paper describes the efficiency of a new class of natural hetero‐ligand Fe(III) chelates (Fe‐NHL) to provide available Fe for chlorotic lemon trees grown in alkaline/calcareous soils. These chelates involve the participation in the reac ...

Abstract:
... Cymbopogon is an aromatic plant valued for its citrus scent aroma. In this article, the effect of saline irrigation water on yield and quality of Cymbopogon schoenanthus L. was evaluated. Compounds of essential oils were identified by gas chromatography–mass spectrometry and/or ¹³C-NMR spectroscopy. Results showed that the growth of the aerial part was not affected at a concentration of 50 mmol Na ...
... 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 ...
... Differences between rootstocks, 'Cleopatra' mandarin and 'Carrizo' citrange, in soil-plant water relations and the influence of these factors on vigor, crop yield, fruit quality and mineral nutrition were evaluated in field-grown Clemenules mandarin trees irrigated at 100% of potential seasonal evaporation (ETc) (control treatment), or irrigated at 100% ETc, except during Phases I and III of fruit ...
... Increasing realization of the ill effects of long sustained, exclusive use of chemical fertilizers, and consistent growing demand from the consumers for fruit quality, coupled with unsustainable productivity of citrus, have fostered experimentation with some alternative cultural practices. Organic culture is claimed to be the most benign alternative. Use of organic materials such as farmyard manur ...
... Quality and mineral content of fruit from internal tree canopies were compared with those from external canopy positions in 4 citrus varities: 'Kinnow' mandarin; 'Redblush' grapefruit; 'Valencia' orange; and 'Lisbon' lemon. Fruit weight, total juice per fruit, peel fresh and dry weight, and rind thickness of fruit from internal canopies of all 4 varieties were significantly higher compared with ex ...
... Since 1985 when eggs of the Fuller rose beetle, Pantomorus cervinus (Boheman), were found by Japanese fruit inspectors under the calyxes of California citrus, researchers have sought to develop alternatives to methyl bromide fumigation as a suitable quarantine treatment for this pest. Three different ages of Fuller rose beetle eggs laid on waxed paper were exposed to gamma radiation doses of 10, 5 ...
