Introduction

The apple (Malus domestica), a valuable and economically significant crop, is grown in India’s northwestern Himalayan region. After Orange, Banana, and Grape, it is the fourth most widely grown fruit worldwide. The tree is native to Central Asia, where its wild ancestor Malus sieversii is still found today. Apples have been cultivated in Asia and Europe for thousands of years. The world’s largest apple grower is China and in India it is grown in the hills of Uttarakhand, Himachal Pradesh, and Jammu & Kashmir in India. The average summer temperature during the active period is about 21-24°C growing season. Apple does this best in areas where trees are dormant. The color development will be better in winter when plenty of sunlight hits. It is possible even at an altitude of 1500 -2700 meters from sea level. 1000-1250 mm well distributed rainfall during the growing season which is most suitable for optimal growth and fertility of apple trees.

Introduction

The banana (Musa parasidiaca) belongs to the Monocotyledons class, the Zingiberales order, and the Musaceae family. It is indigenous to Southeast Asia. They thrive in tropical and subtropical climates and are widely grown in countries such as India, China, the Philippines, Ecuador, Brazil, Uganda, Colombia, and Indonesia. A banana’s average length is 7 to 9 inches, and its diameter is 2 to 3 inches. Bananas are frequently planted during the rainy or monsoon season, when the soil is moist and the young plants can absorb enough water. In tropical and subtropical climates where they are commonly grown, the planting season typically runs from April to June. Planting may take place in September or October in areas with a dry season, following the rainy season.

Introduction The betel vine, scientifically identified as Piper betle L., belongs to the Piperaceae family, which encompasses plants such as pepper and kava. Paan leaves, widely cultivated in countries like Thailand, Philippines, India, Malaysia, Taiwan, Sri Lanka, and various Southeast Asian nations, are commonly used as a popular mouth freshener after meals. This traditional practice is predominantly observed in South Asia and among specific Asian diaspora communities worldwide, where betel leaves are commonly chewed as part of a betel quid or paan, often combined with areca nut or tobacco.

In the cultural traditions of Odisha, offering a bundle of betel leaves symbolizes respect and marks the beginning of auspicious events. Taxonomically, betelvine falls under the genus Piper in the Division Magnoliophyta, Class Magnoliopsida, Order Piperales, and Family Piperaceae.

Depending upon consumer’s preference and yield, different types of cultivars are cultivated.Somewild spp of brinjal are fond in northeast states of India and Malaysia. Solanum insanum, a wild cultivar of the plant, mainlyobserved in the dry and hilly region of west Bengal.Some yellow color brinjal varieties are found in Malaya.

1. Introduction

Eggplant or brinjal (Solanum melongena L. family. Solanaceae) is the major vegetable crop of wet and hot climatic zone of south Asia (Srinivasan and Huang, 2008). After China, India is the second largest brinjal producer country in the world (Majumdar and Das, 2020). It is nutritious vegetable and consumed in throughout the world. Brinjal is considered as Indian native crop and it has been cultivated for last 4000 year. India is known to be the Origin Centre of brinjal cultivation, from where it distributed to throughout the world (Choudhury and Malda, 1968). In India, brijnal crop grow almost throughout the year. Brinjal fruit contains moisture 92.7g, carbohydrates 4.0g, proteins 1.4g, minerals 0.3g, vitamins 124 I.U. and vitamin 12.0mg per 100 g of edible part (Kalra et al., 1988). It is used as vegetable purpose as well as pickle (Singh et al., 1963).

1. Introduction

Chirata (Swertia chirayita) belongs to the family Gentiniaceae, a potential medicinal plant used as bitter tonic in treatment of fever and for curing various skin diseases, is a perennial herb and distributed throughout the eastern Himalayan region of India. The plant is a native of temperate Himalayas, found at an altitude of 1200-3000 m (4000-10000 ft), from Kashmir to Bhutan and in the Khasi hills at 1200-1500 m (4000 to 5000 ft). It can be grown in sub-temperate regions between 1500 and 2100 m altitudes. It is used in traditional medicine to treat numerous ailments such as liver disorders, malaria, and diabetes and are reported to have a wide spectrum of pharmacological properties. Its medicinal usage is well-documented in Indian pharmaceutical codex, the British, and the American pharmacopeia’s and in different traditional medicine such as the Ayurveda, Unani, Siddha, Horopathy and other conventional medical systems. This ethno medicinal herb is known mostly for its bitter taste caused by the presence of different bioactive compounds that are directly associated with welfare of human health. The increasing high usage of Swertia chirayita, mostly whole plant, as well as the illegal overharvesting combined with habitat destruction resulted in a drastic reduction of its populations and has brought this plant to the verge of extinction. The increasing national and international demand for Swertia chirayita has led to unscrupulous collection from the wild and adulteration of supplies. The bitterness, antihelmintic, hypoglycemic and antipyretic properties are attributed to amarogentin (most bitter compound isolated till date) 1, swerchirin, swertiamarin and other active principles of the herb. Due to the high demand, this plant is being cultivated in many places of Darjeeling district both for domestic use within India and for exporting purpose. During our roving survey (2011-2014), it was observed that this high value medicinal plant facing a number of diseases (like seedling blight, leaf spot, Leaf blight etc.), ultimately, cultivation of Swertia chirayita is getting hampered. The quality of plant is affected due to the occurrences of diseases as whole plants part being used as medicinal purpose and also affects the marketing scenario; the demand of good quality chirata is increasing at a rate of 10% annually. To harvest the benefit of megabiodiversity zone of eastern Himalaya needs urgent attention to combat the upcoming epidemic of diseases of chirata. Here, we are trying to throw some light related to present status of diseases of chirata and standard management practices.

Introduction

Chrysanthemum, commonly known as “mums” or “chrysanths,” is a genus of plants that bloom and belong to the Asteraceae family. These plants are native to Asia and northeastern Europe, with China being the primary centre of diversity for the genus. Chrysanthemums are well-known for their attractive and colorful f lowers, and they are popular ornamental plants in gardens, floral arrangements, and as cut flowers.

Chrysanthemum morifolium is a herbaceous perennial flowering crop. It is the second most popular cut flower worldwide, right behind roses, and a significant decorative plant for commerce (Silva et. al., 2013). Certain species’ flowers, such as those of Chrysanthemum morifolium and Chrysanthemum indicum, are rich in nutrients and biologically active substances and are used to make medicinal tea and cosmetics, respectively (Lin et. al., 2010).

Gummosis

Phytophthora spp

Diagnostic Symptoms

• Dark water soaked large patches appear on the basal portions of the stem near the ground level.

Introduction

The innermost layer of the pericarp is the endocarp. The segments are also called “liths”, and the space inside each lith is a locule filled with juice vesicles, or “pulp”. From the endocarp, stringlike “hairs” extend into the locules, which provide nourishment to the fruit as it develops. Citrus fruits are notable for their fragrance, partly due to flavonoids and limonoids (which in turn are terpenes) contained in the rind, and most are juice-laden. The juice contains a high quantity of citric acid giving them their characteristic sharp flavour. The genus is commercially important as many species are cultivated for their fruit which is eaten fresh, pressed for juiceor preserved in marmalades and pickles.

Introduction

Cucurbits, a versatile and economically significant group of plants within the Cucurbitaceae family, encompass a wide array of popular vegetables such as cucumbers, pumpkins, squash, zucchinis, and melons. These cucurbit crops are not only vital components of global diets but also key players in agriculture. Also, cucurbits are used as fibre source and for utensil preparations, decorations, and ceremonial and medicinal purposes (McGrath 2004). However, their productivity and quality are frequently compromised by a range of diseases. In this chapter, we embark on a comprehensive exploration of the diseases that afflict cucurbits, including their names, symptoms, causative agents, etiology, disease cycles, favourable conditions, and strategies for effective management.

Introduction

Roses, widely cultivated as cut flowers in greenhouses, as entire plants in nurseries, or within home gardens, encounter common issues across these diverse growing environments, including black spot, Botrytis blight, downy mildew, powdery mildew, and rust. Specific challenges like downy mildew and rose rosette gained prominence in the 2010s. The susceptibility of roses to various diseases varies by geographical region; for instance, rose replant disease is a concern in Europe but not in North America. Greenhouses and tropical climates, as seen in Central and South America, face heightened issues with powdery mildew, downy mildew, rust, and Botrytis blight. Disease management proves costly and can constrain rose production, prompting innovations like the adoption of hydroponics in Colombia, leading to improved pest control, enhanced rose quality, and increased productivity.

1. Ginger (Zingiber officinale)

‘Ginger’, which originated in Southeast Asia has a long history that goes back over 5000 years when the Indians and Ancient Chinese considered it as a tonic root for all ailments. At an early date it was exported to Ancient Rome from India and was used extensively by the Romans. Subsequently it was cultivated in several other countries for its medicinal value. Ginger is cultivated in most of the states of India. Kerala and Meghalaya are the major ginger growing states. India’s production of ginger constitutes about 50 per cent of the total world’s production.

Ginger is an erect, herbaceous , perennial, flowering plant, the rhizome of which is used as a spice. Ginger is an ancient spice and is a common ingredient in many Asian foods and is used in soups, curries, noodles, stews etc. It is widely used to flavor beverages, such as tea, coffee, lemonades, cocktails etc. In many places across the world ginger is used in sweets, alcoholic beverages, such as ginger beer and wine.
