The Turkey Tail mushroom, also known scientifically as Trametes versicolor, is a type of polypore medicinal fungus that may be found growing on tree trunks worldwide. Even though T. versicolor is one of the white-rot fungi studied the most extensively, the commercial applications of this fungus and its metabolic products are still in their infancy....

The book describes the diverse organisms and agents that cause disease - plant pathogens. There are five chapters describing true fungi, other eukaryotic fungal-like organisms, bacteria, viruses and nematodes, respectively. In the book we address the mechanisms of pathogenicity and defence, or immunity as the latter is known as at the cellular leve...

In India, around 9,600 metric tonnes (MT) of commercial grade fungicides of are used annually to combat crop diseases. Meanwhile chemical control of plant diseases has limits, people are becoming more aware of the need to adopt biological control strategies that reduce plant diseases to a reasonable degree while ensuring production is sustainable,...

The book introduces the nature, causes, and impact of plant diseases, briefly describes the history of plant pathology as a scientific discipline, and introduces the disease cycle as a critical tool for understanding disease development and devising appropriate management strategies. The book describes the diverse organisms and agents that cause di...

The tomato, one of the world's most extensively cultivated and consumed vegetable crops is negatively impacted by various pathogens. This study aimed to observe the differentially expressed proteins in tomato samples in plant-pathogen-biocontrol interactions. The fungal pathogen associated with wilted plants were isolated and identified based on it...

Since the beginning of recorded history, maize has been cultivated and evolved. Globally, maize is among the three leading staple food grains. The domestication of maize is believed to have begun in Central Mexico approximately 9000 years ago, making it one of the oldest crops cultivated by humans and one of the world’s top production grain crops f...

Vermiculture approach the synthetic rearing of worms to decompose natural meals wastes right into a nutrient-wealthy material. The output of vermiculture is known as vermicompost and the leachate of the vermicomposting process, referred to as vermi-leachate, is a brownish-coloured substance created via way of means of the passage of water withinsid...

Ganoderma species are a large and diverse genus of wood-rotting fungi that are found worldwide. It is made up of species that cause white rot on a wide variety of tree species. It has a long history of use as a medicinal mushroom in Asia and contains a variety of pharmacological properties associated with immunomodulatory action. It grows on decayi...

Abiotic and biotic factors conspire to keep crop output at a bare minimum. In agricultural production, to combat these factors, beneficial microorganisms are used to boost yields and as a substitute for synthetic fertilizers and fungicides. The genus, Chaetomium is well-known for its fast, saprophytic colonization, similar to that of Trichoderma. C...

Plum and their hybrids are facing complications. Diseases, insect pests, and the abiotic factors wreak havoc on the quantity and quality of fruits and vegetables from production to consumption. Many of the diseases and pests that affect plums are found in all Prunus spp., growing outside of earlier reported areas. Information on diseases, pests, an...

Purpose: There is a particular paucity of information emanating from Tamil Nadu state, where organic farming appears to have a promising future. Some of the constraints revealed from primary sources suggest to the importance for a comprehensive study that would resulting in a strategic model framework for sustainable organic farming in Tamil Nadu....

Powdery mildew is an omnipresent disease that reduces the yield and quality of pea crops (Pisum sativum L.). To examine the powdery mildew pathogen’s morphological, molecular, and genetic diversity, we collected samples of powdery mildew-affected pea crops from ten distinct locations in the Nilgiris district of Tamil Nadu, India. The pathogen Erysi...

Medicinal plants are broadly cultivated in the fields with utmost care to meet the growing demand for health care drugs and products. Frequently, they are infected by pathogens and parasites when cultivated in commercial agroecosystems. Devastating diseases can result in huge yield losses increasing the importance of these pathogens in medicinal pl...

The present investigation is designed for the characterization and application of phytase from Aspergillus tubingensis by solid state and submerged fermentation techniques practice. Different parameters such as carbon source, nitrogen source, pH, mineral concentration, temperature, inoculum size, and inducer concentration were employed for the opti...

The occurrence of various diseases like cancer, cardiovascular, aging, and other associated problems are due to the frequent consumption of carcinogenic chemicals added food along with related activities. Our present investigation is focused on anticancer and antioxidant profiling of phycocyanin pigments isolated from Spirulina sp. The candidate sp...

The speedy growth of human population, the issues arising out of pollution, demand of invertase yield and dumping of wastes from agro-industry have been influenced to find new solutions for microbial enzymes. In this study, an attempt was made to produce the invertase by yeast isolated from honey bees. Influence of various process parameters like n...

The global COVID-19 pandemic has hit the agriculture sector hard around the world. A study was conducted to assess the impact of the pandemic on cropping patterns, crop management, usage of chemical inputs and their organic alternatives, harvesting, and marketing avenues through a survey approach in the two states of Kerala and Tamil Nadu in India....

India has moved from an era of food shortages to a status of food self-sufficiency through improved modern agricultural technologies and sustainable agricultural practices. However, various constraints exist during the cultivation of the crop, which limits its production and productivity. In achieving the green revolution, chemicals have played a s...

Aim: The objective was formulated to screen the extracts of medicinal plants for tapping the antimicrobial activity against Collectotrichum capsici. Further, the work was planned to characterize and identify the nature of antimicrobial compounds and their functional groups. Methodology: Extracts of eleven medicinal plants were tested against the my...

Black scurf in potatoes is caused by the pathogenic fungus Rhizoctonia (R.) solani, and is a serious disease that results in both quantitative and qualitative losses in potato yields worldwide. To manage this disease in an eco-friendly manner, isotonic aqueous formulation of Chaetomium (C.) globosum was developed and tested for disease control effi...

Pleurotus pulmonarius belonging to the white-rot fungal basidiomycetes group secretes extracellular ligninolytic enzymes for the degradation of agro-residues. The present study was carried out to evaluate the efficacy of different agro-residues for the enhanced production of ligninolytic enzymes and to authenticate their ability by protein analysis...

Personnel in State Department of Agriculture requires several media tools for the technology transfer process. Thanjavur District was purposively selected for the study. A simple random sampling approach was used to determine the sample size of 30. For the investigation, an ex post facto research design was developed. A semi-structured interview sc...

The book is intended to provide comprehensive introduction to the important aspects of the field of forest pathology and tree diseases. The book is arranged in two major parts. The fundamental chapters, present forest diseases, pathogens, epidemics, and management that is applicable to all forest trees. The applied chapters on the individual crops...
