Introduction- In today’s era due to modernization and civilization people follows modern techniques of cultivation which is starting from seed viability study then for nursery adding fertilizers in land and for treating disease and fulfilling their nutrients value adding or spraying chemical fertilizers which leads to hazards effect in environment on every creature. Aacharyas found natural solutions for every plant issue many years back they already mentioned in Vrikshayurved, how to diagnose and treat different kind of plant diseases more naturally and authentically. Objective- This article aims to diagnose and treat plant diseases according to Vrikshayurved. Materials and methods- Study performed on Onion seedlings (Allium cepa) under the observation of Directorate of Onion and Garlic Research Institute, Rajgurunagar, Pune. Onion seedlings were treated by Kunap jal and Madhuyastyadi Kwath. Disease of Onion seedlings were diagnosed and treated by Vrikshayurved methods using Kunap jal and Madhuyashtyadi Kwath. Results- The Vrikshayurved methods showed around 80-85% reduction in curling of leaves, 100% reduction in yellowish discoloration, 100 % reduction in dryness of leaves. Vrikshayurved intervention improved growth rate drastically. Conclusion- Vrikshayurved intervention improved curling, dryness and yellowish discoloration of leaves significantly. It also doubled growth rate of the onion seedlings. It indicates that Vrikshayurved methods are applicable in today’s era.

Causative Agents

Disease control is largely based on the use of fungicides, bactericides, and insecticides—chemical compounds toxic to plant invaders, causative agents, or vectors of plant diseases. However, the hazardous effect of these chemicals or their degradation products on the environment and human health strongly necessitates the search for new, harmless means of disease control. There must be some natural phenomenon of induced resistance to protect plants from disease. Elicitors are compounds, which activate chemical defense in plants. Various biosynthetic pathways are activated in treated plants depending on the compound used. Commonly tested chemical elicitors are salicylic acid, methyl salicylate, benzothiadiazole, benzoic acid, chitosan, and so forth which affect production of phenolic compounds and activation of various defense-related enzymes in plants. Their introduction into agricultural practice could minimize the scope of chemical control, thus contributing to the development of sustainable agriculture. This paper chiefly highlights the uses of elicitors aiming to draw sufficient attention of researchers to the frontier research needed in this context.

Harmful Effects

Wetlands are home to numerous species of fish, birds, and reptiles. The enormous roots of the mangrove trees act as shelter to small fish, reptiles, and amphibians. Pesticides and agro-chemical fertilizers have been playing a very pivotal role in the degradation of the land and the water bodies. The different herbicides that are present in wetlands are Dicamba, Endothall, MCPA, Triallate, Trifluralin, 2, 4-D, and insecticides Carbaryl, Carbofuran, Fenvalerate, Malathion, Parathion, and Terbufos. These pesticides have been provided with the aim of catering to the security of the crops which are highly vulnerable to the pests. However, harmful effects of pesticides on wetland species have been a concern for long time. Wetlands constitute one such habitat threatened by the pesticides. But there has been a lack of comprehensive research in this direction. The chapter will identify the gaps in the current research and will review the status of Indian wetlands with special reference to pesticides and their impact.

Future Challenges

Detection, identification, and quantification of plant diseases by sensor techniques are expected to enable a more precise disease control, as sensors are sensitive, objective, and highly available for disease assessment. Recent progress in sensor technology and data processing is very promising; nevertheless, technical constraints and issues inherent to variability in host–pathogen interactions currently limit the use of sensors in various fields of application. The information from spectral [e.g., RGB (red, green, blue)], multispectral, and hyperspectral sensors that measure reflectance, fluorescence, and emission of radiation or from electronic noses that detect volatile organic compounds released from plants or pathogens, as well as the potential of sensors to characterize the health status of crops, is evaluated based on the recent literature. Phytopathological aspects of remote sensing of plant diseases across different scales and for various purposes are discussed, including spatial disease patterns, epidemic spread of pathogens, crop characteristics, and links to disease control. Future challenges in sensor use are identified.

Increased Activity

All essential nutrients can affect the incidence and severity of plant diseases. Although silicon (Si) is not considered as an essential nutrient for plants, it stands out for its potential to decrease disease intensity in many crops. The mechanism of Si action in plant resistance is still unclear. Si deposition in plant cell walls raised the hypothesis of a possible physical barrier to pathogen penetration. However, the increased activity of phenolic compounds, polyphenol oxidases and peroxidases in plants treated with Si demonstrates the involvement of this element in the induction of plant defense responses. The studies examined in this review address the role of Si in disease control and the possible mechanisms involved in the mode of Si action in disease resistance in plants.
