A Brief Overview of Major Citrus Diseases and Pests and Its Management | Chapter 10 | Current Topics in Agricultural Sciences Vol. 1

The worldwide impact of a variety of insects, pests, and diseases has resulted in poorer output and a shorter productive life span for citrus trees. Pathogens or causal organisms in the form of bacteria, fungi, viruses, nematodes, and virus-like pathogens are responsible for the occurrence of several seeds, soil and air borne diseases, and pests infested/infected symptoms in citrus plant parts, resulting in economic losses to citrus growers in the citrus belts. Pest infestations, as well as fungal, bacterial, and viral diseases, are more frequent in the cultivated area when plants are exposed to high humidity and heavy rains from May to September. As a result, the main goals of this chapter were to identify the most important citrus-harming species and to highlight the best management practises for them. Citrus Greening, Citrus Canker, Orange Scab, Leaf and Fruit Spot, Blue mould, Phytophthora Root Rot, Sooty Mould, Citrus Wither Tip, Armillaria, Sooty Blotch, Tristeza Virus, Citrus Yellow Mosaic Virus, Grey Mosaic Virus, Grey Mosaic Virus, Grey Mosaic Virus, Grey Mosaic Virus, Grey Mosaic Virus, Grey Mosaic Furthermore, it has been emphasised that chemical control is solely reliant on the use of chemicals to manage such dangerous pests and illnesses. As a result, using integrated orchard management approaches in conjunction with sanitation practises and closely monitoring the appearance and development of important pests and diseases is an alternate method of reducing the usage of chemical pesticides and insecticides.

Mycorrhial Fungal Application in Citrus Plants | Book Publisher International

 The interaction of citrus with arbuscular mycorrhizal fungus (AMF) has been a major research focus and international hotspot in the study of citrus plants in recent years. A wide number of pot experiments have conclusively demonstrated that AMF inoculation significantly improved citrus plant development and expedited the uptake of minerals in the soil, particularly P, Fe, Cu, K, and Ca. AMF, on the other hand, causes root hairs to appear in citrus plants under low P conditions, demonstrating that mycorrhizal fungus and root hairs work together to increase nutrient absorption. In addition, Yangtze University's Prof. Qiang-Sheng Wu headed a team that did a lot of good work on the many mechanisms of arbuscular mycorrhizas in boosting citrus drought tolerance. In the field, AMF inoculation trials have been attempted. As a result, this book presents a thorough overview of mycorrhizal fungi's roles on citrus, as well as an examination of mycorrhizal fungi's population diversity on the citrus rhizosphere and the proliferation of indigenous mycorrhizal fungi. The book also discusses how to inoculate potted citrus at the nursery, how to sterilise substrates, how to evaluate applied AMF in the field, and how to maintain citrus mycorrhizas in the field. This book can be used as a technical reference on mycorrhizal fungi's use in citrus. It also includes various mycorrhizal research field examples. This book can be used as a theoretical textbook and reference book for pomology and citrus researchers, as well as for mycorrhiza researchers and graduate students.

Influence of the Rootstock on the Performance of ‘Valencia Late’ Sweet Orange in the Gharb Region (Northwestern Morocco) | Chapter 1 | Research and Development in Agricultural Sciences Vol. 3

 

The effect of 14 rootstocks on yield, yield efficiency, tree size and fruit quality of ‘Valencia late’ sweet
orange was studied in the Gharb region (northwestern Morocco). Over 5 years of production, total
cumulative yield was the highest on Citrumelo 4475 (11) and PT B6 Z13 (5). In terms of productivity,
Citrumelo 4475 (11), Citrus volkameriana (25), the Sunki mandarin x PT (39) hybrid, Citrus
macrophylla (24) and the Sunki mandarin x PT 16 hybrid were the most efficient rootstocks. This
study also revealed that the use of some rootstocks improved significantly juice content of Valencia
late fruits. These rootstocks included Citrus volkameriana (25), PT B6 CZ 24 (3), PT B6 CZ 13 (5),
Cleopatra mand x CC (30), Sunki mandarin x PT (16), Citrumelo 4475 (11) and Citrumelo 1452 (41).
In terms of acidity and Brix, the study has identified rootstocks that enhanced both fruit quality
parameters, namely Carrizo citrange (7), Sunki mandarin x PT (17), Citrumelo 1452 (41), Citrumelo
4475 (11), Sunki mandarin x PT (17), Sunki mandarin x PT (16) and PT B6 CZ 24 (3).
