Field Problems of Citrus Crop in North India
Citrus belongs to the Rutaceae family, which gets its name from the genus Ruta L. in the Aurantioideae subfamily. More than 70% of the world's total citrus output is produced in the northern hemisphere, mostly in China, Brazil, India, the United States, and Mediterranean nations. It is subjected to a variety of biotic stresses. In many regions of the world, citrus diseases are the most major limiting factor in growing and maintaining production and productivity. As the number of new mono-specific and monoclonal citrus plantations becomes greater, and abiotic stress loads exacerbate the situation, such concerns become increasingly relevant. Some diseases only reduce yield and quality, while others have the ability to wipe out a whole citrus sector. Some maladies, such as those caused by nematodes and the oomycete Phytophtora sp., are found in the majority of producing locations.
