“…Increasing attention has targeted the use of microorganisms (de-Moura et al, 2021), UV light (Abbey et al, 2019), organic and inorganic salts and acids (Zaker, 2014), and natural compounds (Sitohy et al, 2007;Abbas et al, 2020;Atallah et al, 2021) to control fungal infections. Although synthetic fungicides are still the most effective agents against postharvest fungal diseases in various fruits, they have significant drawbacks, including high cost and handling hazards, pathogens' resurgence, biodiversity loss, increased toxicity, high residues, threatening human health, and environment (Mari et al, 2014;Sajeena et al, 2019). Fungi can also rapidly increase their resistance to one fungicide.…”

The 7S globulins (seed storage glycoprotein) isolated from soybean and chickpea seeds have the antifungal potential against the pathogenic fungus (Botrytis cinerea) causing gray mold in grapes assessing table grapes in vitro or postharvest by comparing with synthetic fungicide, Switch 62.5 WG. Conventional microbiological procedures estimated the in-vitro antifungal potential of the 7S globulins, such as linear growth curves and scanning electron microscopy (SEM). Soybean-7S significantly inhibited the in-vitro growth of Botrytis cinerea by about 64.44%, 66.64%, and 76.67% when applied at 50, 100, and 200 μg/mL, respectively, followed by chickpea 7S with growth reduction of 52.22%, 54.44%, and 66.67%, respectively. The synthetic fungicide (Switch 62.5 WG) induced higher growth inhibition extents (83.33% and 86.66%) when applied at 50 and 200 μg/mL, respectively. The 7S-exposed B. cinerea displayed swollen hyphae compared with the control under scanning electron microscope examination. The 7S derived from soybean and chickpea inhibited gray mold development in table grapes when applied at 200 and 400 μg/mL for 30 days after infection with B. cinerea. The maintained disease severity was also minimal (40% and 25% for soybean-7S and chickpea-7S, respectively). An increased level of treatment (400 μg/mL) highly reduced the disease severity to only 7.5% after 30 days of storage at cold conditions for both proteins. The 7S globulin from legume seeds can be an alternative to synthetic fungicides for controlling B. cinerea as a postharvest treatment. Developing these legume proteins as natural fungicides could also progress for the safe control of various plant pathogens, causing drastic crop losses.

“…Cultural and physical methods are not among the muchadopted crop management measures. 1 Disease management using fungicides, the last resort for plant protection, is still continuing as the predominant plant protection tool. 2 The indiscriminate use of synthetic pesticides for the management of the plant diseases created huge environmental risks and toxic health hazards on human.…”

The crop production is turn down by many pathogens, weeds, insects comprising 36.5% of annual loss under field and 14% during storage conditions. Among many practices adopted to manage plant diseases, use of synthetic chemicals is more convinced and are adopting as a last resort of the disease management worldwide. Despite of its efficacy, use of chemicals is threatening the environments, health of human and animals because of its residual toxicity, non- specificity, resurgence and costly nature. Emerging agriculture is now being replacing the hazardous chemicals through the use of biological and botanicals. The botanicals growing naturally possess numerous antimicrobial metabolites that act against various pathogens reducing the disease severity with out having adversities on animal health and environment. Neem, Melia, Datura, garlic, ginger, turmeric, eucalyptus, onion, basil, tobacco, nettle, black pepper, chilli etc. have antimicrobial metabolites such as phenols, phenolic acids, quinones, flavones, flavonoids, flavanols, tannins, coumarins etc. These constituents can be potential pesticides. From in-vivo and in-vitro studies on their effectiveness it has been proved that they can be the best substitutes for synthetic chemicals in agriculture. Among the plant species in world, only 10% of the plant species have been reported to have pesticidal activities. Identification of such plant species and production of plant-based formulation is most essence for economic and eco-friendly management of plant diseases. Therefore, having a better understanding of these alternative pesticides could be beneficial for engaging in sustainable agriculture, especially given that they are less dangerous, practical from an economic standpoint, simple to use and capable of managing pests and pathogens in both fields and stores (postharvest). The review is subjected to study the efficacy of botanical extracts for the management of crop diseases as a better alternative to the chemicals and it summarizes the findings from previous researches

IoT Enabled, Leaf Wetness Sensor on the Flexible Substrates for In-Situ Plant Disease Management

Early plant disease detection and providing the control measures have become highly desirable to improve crop yield. Leaf wetness duration (LWD) is one of the essential parameters related to the development of fungal disease on the leaf canopy. To measured LWD, the leaf wetness sensor (LWS) is widely used. Commercially available LWS are made on printed circuit board (PCB) technology, which has an operational issue during field deployment such as weight of the sensor, contact resistance between the sensor and the leaves, form factor and most importantly, affordability. To mitigate the issues associated with the commercially available LWS, in this work, we have fabricated the in-house IoT-enabled and affordable electronic leaf wetness sensor on the flexible substrates, which is used for integrated plant disease management. Fabricated LWS comprises the interdigitated electrodes (IDEs) on the polyimide flexible substrate. The lab measurement results indicate that fabricated LWS on the flexible substrates offers a response of about 36000% when LWS is exposed to water w.r.t air. The observed response time of the fabricated LWS is about 10 seconds and hysteresis of about ± 4 %. Further, sensor capacitance changes only by 6% over a temperature range from 20 °C to 65 °C. Furthermore, three fabricated sensors LWS and in-house developed internet of things (IoT) enabled systems are deployed on the Ocimum tenuiflorum (Tulsi) medical plant. Field measurement indicates that measured LWD using the fabricated flexible LWS and commercially available LWS (Phytos 31:LWS-L12), METER Group, Inc. USA) shows the absolute difference of 30 minutes.
