Ascochyta Blight
Diagnostic Symptoms
• All above ground parts of the plant are infected.
• Round or elongated lesions, bearing irregularly depressed brown spot and surrounded by a brownish red margin on leaf.
• Similar spots may appear on the stem and pods.
• Spots on the stem and pods have pycnidia arranged in concentric circles as minute black dots.
• When the lesions girdle the stem, the portion above the point of attack rapidly dies.
• If the main stem is girdles at the collar region, the whole plant dies (Fig.1).

1. Rhizoctonia aerial blight / Web blight
Symptoms
• The soybean Rhizoctonia aerial blight is a damaging foliar disease that quickly defoliates plants in warm, humid climates.
• Rhizoctonia solani causes soybean aerial blight, which manifests as leaf and pod spots, leaf blight, defoliation, lesions on the stem and petiole, a mycelium that resembles a cobweb, and sclerotia that form on diseased leaves.
• The plant’s lower or central sections are where infection starts, and it progressively spreads upward.
• The leaves first have wet patches that eventually become green to reddish brown in color before turning tan, brown, or black.
• Small spots at first eventually combine to cover a significant portion of the leaf.
• Affected leaves droop and stick to the pods and stem underneath them during the aerial blight phase, infecting the pods and seeds in the process.

Tikka or Leaf Spot
Cercospora arachidicola/ Phaeoisariopsis personatum
Diagnostic Symptoms
• Disease is caused by two different pathogens, namely, Cercospora arachidicola and Phaeoisariopsis personatum.
• The two pathogens mostly occur on the same leaves.
• The Cercospora arachidicola appears about a month earlier than the Phaeoisariopsis personatum.
• The two pathogens cause symptoms differing each other. Early leaf spot
• Sub-circular dark brown spots having 1 to over 10 mm diameter are produced on the upper leaflet surface.
• Spots are of lighter shade of brown on the lower side of the leaflets.
• Yellow halo is seen around the brown spots.
• Dark brown in colour on the upper leaflet surface where most sporulation occurs and a lighter shade of brown on the lower leaflet surface.

1. Blast
Pyricularia grisea
Diagnostic Symptoms
• Crop is susceptible to the disease during all stages of its growth, from seedling to grain formation stage.
• In young seedlings, lesions are generally of spindle shaped, however lesions of different sizes may also be observed.
• In the beginning the spots have yellowish margin and grayish centre. Later, the centres become whitish grey and disintegrate.
• Lesions are isolated in the beginning and afterwards they may soon coalesce. The distal portion of the leaves beyond the lesions may hang and drop off.
• In older plants, the disease appears on leaf blades with typical spindle shaped spots.
• Under congenial conditions, such spots enlarge, coalesce and form bigger lesions.
• Lesions are like those on the seedlings and are about 0.3-0.5 cm in breadth and 1-2 cm in length. Apices of the infected leaves beyond the lesions hang down and sometimes break.
• Stem infection causes blackening of the nodal region, penetrating into the tissues.

1. Downy Mildew (Green Ear)
Sclerospora graminicola
Diagnostic Symptoms
• Characteristic symptoms of the disease are pale, chlorotic, broad streaks extending from base to tip of leaves.
• At the advancement of disease, the leaf streaks turn brown and the leaves become shredded longitudinally.
• In severe infection, the downy fungal growth can be seen on the upper as well as lower surface of the leaves.
• Infected plants fail to form ear but if formed, they are malformed to green leafy structures.
• Complete ear can be transformed into leafy structure.
• Pathogen transformed all floral parts such as glumes, palea, stamens and pistils into green linear leafy structures of variable lengths and no grains are produced.
• Partial infection of ear head is observed in which some grains are produced and rest of the ear head is converted in to a green ear(Fig-1).

Loose Smut
Sphacelotheca cruenta
Diagnostic Symptoms
• Affected plants can be detected before the ears come out.
• Shorter than the healthy plants with thinner stalks and marked tillering.
• Ears come out much earlier than the healthy.
• Glumes are hypertrophied and the ear head gives a loose appearance than healthy.
• Sorus is covered by a thin membrane which ruptures very early, exposing the spores even as the head emerges from the sheath(Fig-1).

Banded Leaf and Sheath Blight
Diagnostic Symptoms
• From the crop’s seedling stage until crop maturity, this pathogen can infect the plant at any point in its growth.
• The disease initially appears on the first and second leaf sheaths above the ground, and it eventually spreads to the ears, where it results in ear rot.
• The hallmark symptoms of ear rot include the presence of light brown, cottony mycelium on the plant’s ear, small, rounded black sclerotia, early ear drying, and caking of the ear sheath.
• When there is humidity, the infection that first appears on the lower sheath extends to the upper sheaths, causing leaf sheath rot and complete leaf drying.
• When the condition worsens, the majority of the plant’s leaves become blighted, and easily detachable sclerotia form on the lesions.
• The disease manifests as a straw-colored, wet, irregular to roundish patch on both leaf surfaces on the basal sheath.

Rust
The rust of wheat has been studied more than any other disease in the world. K.C. Mehta and colleagues conducted exceptional research on the disease in India. There are three recognized wheat rusts. These include Puccinia graminis tritici, which causes black stem rust; Puccinia recondita, which causes brown rust (leaf rust); and P. striiformis, which causes yellow rust. Considering their later seasonal arrival, brown and yellow rusts inflict more damages than black rust.
1. Black or Stem Rust
Diagnostic Symptoms
• Symptoms are produced on almost all aerial parts of the wheat plant but are most common on stem, leaf sheaths.
• Brown pustules of uredina appear on lower surface of the leaves, leaf sheaths and the stems, and on the spikes. which give them a rusty appearance.
• Uredina form urediniospores , which are the repeating spores.
• Uredina gradually start producing teliospores and finally transform into telia.

1. Blast
Diagnostic Symptoms
• Pathogen attacks the crop at all stages of crop growth.
• Symptoms appear on leaves, nodes, rachis, and glumes. On the leaves, the lesions appear as small bluish green flecks, which enlarge under moist weather to form the characteristic spindle shaped spots with grey centre and dark brown margin (Leaf blast).
• Spots coalesce as the disease progresses and large areas of the leaves dry up and wither. Severely infected nursery and field appear as burnt.• Black lesions appear on nodes girdling them. The affected nodes may break up and all the plant parts above the infected nodes may die (nodal blast).
• During flower emergence, the fungus attacks the peduncle and the lesion turns to brownish-black which is referred to as rotten neck / neck rot / panicle blast (neck blast).
• In early neck infection, grain filling does not occur while in late infection, partial grainfilling occurs (Fig.1).

Abstract
India’s grape industry has emerged as a key contributor to horticultural exports, driven by increasing production, evolving market strategies, and trade liberalization. This chapter analyses the trends, growth, instability, and export potential of both fresh (HS 080610) and dried grapes (HS 080620) from India between 2004 and 2023. While, India ranks among the top global producers, the fresh grape segment has seen consistent growth in exports, supported by initiatives like APEDA’s GrapeNet traceability system and private-sector innovation through companies like Sahyadri Farms and Mahindra Agri. In contrast, the dried grape segment, despite high growth potential, has faced volatility and continues to show a trade deficit. Using compound growth rates (CGR) and the Cuddy-Della Valle Index (CDVI), the study evaluates performance across production, trade value, and instability metrics. Exports potential maps highlight untapped markets such as the United States, EU, and Southeast Asia. Strengthening post-harvest infrastructure, ensuring compliance with international quality standard, and investing in value addition remain critical for India to enhance its global competitiveness in grape exports.

Abstract
The agricultural sector in India is predominantly characterized by small and marginal landholders who face numerous challenges, including limited access to markets, resources, and technology. Farmer Producer Organizations (FPOs) have emerged as a collective model to address these challenges, enabling farmers to achieve economies of scale and enhance market linkages. This study explores the strategic imperatives for empowering FPO's to access international markets, focusing on their ability to improve business capacities, adopt global standards, and invest in infrastructure. Key strategies include nurturing FPOs through competency development, resource pooling, and collaborations with institutions and private players. The paper highlights the importance of integrating FPOs into global value chains, enhancing their market adaptability, and fostering long-term sustainability through community-driven investments. The findings underscore that tailored support and strategic interventions can transform FPOs into viable entities capable of driving economic growth and improving the well-being of small-scale farmers.

Abstract
Non-tariff barrier (NTBs), particularly Sanitary and Phytosanitary (SPS) measures and Technical Barriers to Trade (TBT), have increasingly shaped the contours of international trade. While originally instituted to safeguard human, animal, and plant health and ensure product standards, these regulatory mechanisms are often criticized for functioning as covert instruments of protectionism. This chapter undertakes a comprehensive analysis of the dual nature of SPS and TBT measures, acknowledging their public policy rationale while critically examining their role in distorting trade flows, increasing compliance burdens, and eroding competitiveness, especially for exporters in developing economies. It highlights the economic ramifications, operational challenges, and policy complexities inherent in their implementation. Drawing from global best practices and multilateral frameworks, the study advocates for targeted strategies such as regulatory harmonization, improved transparency, enhanced capacity-building and robust dispute resolution mechanisms. These approaches are essential not only to prevent the misuse of SPS and TBT provisions but also to facilitate equitable market access and support rules based international trading system. The chapter emphasizes that achieving this balance is critical for fostering inclusive economic growth, promoting global competitiveness, and strengthening cooperation among nations in an increasingly interconnected world.

Abstract
India’s agriculture sector plays a critical role in economic development, offering employment to a significant rural population and contributing notably to GDP. Despite limited natural resources, India is among the world’s top producers of various crops and livestock. However, post-harvest losses, infrastructure gaps, and limited value addition hamper its full export potential. In recent years, agricultural exports have surge, with rice, spices, sugar, buffalo meat, and marine products emerging as key contributor. India has also expanded its export footprints across major global markets, including the USA, China, Bangladesh, and the UAE. Recognizing the strategic importance of agri-exports for economic growth, employment generation, and rural development, the government has launched initiatives such as the Agriculture Export Policy (AEP), Agri Export Zones (AEZs), and Market Access Initiatives (MAI). These measures aim to boost market access, infrastructure, and competitiveness. The integration of e-NAM, focus on quality standards, branding through Geographical Indications (GI), and establishment of Agri-Cells in key countries further support India’s goal of becoming a global agriexport powerhouse. This work underscores the importance of a coherent export strategy to enhance farmer income, promote sustainable practices, and position India as a key player in the global agricultural value chain.
