Citrus is the important fruit crop in the world. It occupies an important place in the wealth and economy of India as third largest fruit industry after mango and banana. Citrus canker caused by Xanthomonas citri subsp. citri is a damaging disease of acid lime. It is identified as a major threat in the region affecting leaves, twigs, petioles, branches, fruit stalk and fruits that causes considerable damage both quantitatively and qualitatively. Canker infected sample of acid lime leaves were collected from different agroclimatic regions of Vidarbha. The bacterium were isolated, identified and purified cultures were maintained on NA slants. The virulence test of causal organism was confirmed along with symptoms in pot culture experiment using syringe method. Pathogenic ability of different isolates was confirmed and observed that isolate Xac-2 was comparatively highly virulent to initiate water soaked lesion and fully developed symptoms within 15 to19 days. Efficacy of different combination of chemicals, botanicals and bio-agents against Xanthomonas citri subsp. citri was assessed. Among the alcoholic and aqueous plant leaf extracts neem (Azardiricta indica) at all concentrations found most effective in alcoholic extracts by developing 13.45 mm, 11.70 mm, 10.12 mm and 8.2 mm of inhibition zone at 20% 15%, 10% and 5% respectively. Among fruits extracts, alcoholic extract of Kokam (Garcinia indica) gives highest inhibition zones 17 mm, 15.0 mm, 6.9 mm and 0 mm at 20% 15%, 10% and 5% concentrations and found to be most effective. Among flower extracts, alcoholic extract of lakh (Lathyrus odoratus) showed highest inhibition zones 13.14 mm, 9.23 mm, 8.00 mm and 6.23 mm at 20% 15%, 10% and 5% concentrations. Among the extracts of different vegetative parts of plants alcoholic extract of garlic (Allium sativum) produced highest inhibition zones 16.20 mm, 13.40 mm, 7.23 mm and 0.00 mm at 20% 15%, 10% and 5% concentrations.

The applications and benefits of nanotechnology in the agricultural sector have attracted considerable attention, particularly in the invention of unique nanopesticides and nanofertilisers. The contemporary developments in nanotechnology are acknowledged and the most significant opportunities awaiting the agriculture sector from the recent scientific and technical literature are addressed. This review discusses the significance of recent trends in nanomaterial-based sensors available for the sustainable management of agricultural soil, as well as the role of nanotechnology in detection and protection against plant pathogens, and for food quality and safety. Novel nanosensors have been reported for primary applications in improving crop practices, food quality, and packaging methods, thus will change the agricultural sector for potentially better and healthier food products. Nanotechnology is well-known to play a significant role in the effective management of phytopathogens, nutrient utilisation, controlled release of pesticides, and fertilisers. Research and scientific gaps to be overcome and fundamental questions have been addressed to fuel active development and application of nanotechnology. Together, nanoscience, nanoengineering, and nanotechnology offer a plethora of opportunities, proving a viable alternative in the agriculture and food processing sector, by providing a novel and advanced solutions. © 2017 Society of Chemical Industry.

“…Streptocycline (streptomycin sulphate, 500 ppm) in combination with copper oxychloride (0.2%) followed by Bronopol (2-bromo-2-nitropropane-1,3-diol, 500 ppm) and copper oxychloride (0.2%) were found to be effective in the management of bacterial blight of pomegranate 15,16 . Alternative chemicals and biologicals, such as spraying plant growth regulators ethylene (200 ppm) 17 , nano copper at 2 ppm 18 , bacterial antagonistic such as Pseudomonas fluorescens and Bacillus subtilis 19 , Streptomyces violaceusnige 20 and plant extracts from pongamia, neem, coleus and periwinkle have been shown to effectively retard the growth of Xap under in vitro conditions 21 . Integrated disease management with cultural practices, orchard sanitation, timely application of pesticides along with biologicals and botanicals are effective in reducing bacterial blight severity in pomegranate 16 .…”

Bacterial blight caused by Xanthomonas axonopodis pv. punicae is a major disease of pomegranate. Bacterial blight drastically reduces the yield and quality of fruits, which are critical for pomegranate production. Precise and early diagnosis of bacterial blight is crucial for active surveillance and effective management of the disease. Symptoms based disease diagnostic methods are labor-intensive, time-consuming and may not detect disease on asymptomatic plants. DNA-based disease diagnostics using polymerase chain reaction (PCR) are reliable, precise, accurate and quick. PCR coupled with agarose gel electrophoresis (PCR-AGE), PCR coupled with capillary electrophoresis (PCR-CE) and real-time PCR (qPCR) were applied for the early and accurate diagnosis of bacterial blight in pomegranate. PCR-CE and qPCR were capable of diagnosing bacterial blight 6 to 10 days before symptom appearance, with detection limits of 100 fg and 10 fg of bacterial DNA respectively. However, conventional PCR-AGE detected pathogen at the onset of disease symptoms with a detection limit of 10 pg of bacterial DNA. qPCR detected bacterial blight in orchards that did not show any disease symptoms. Our data demonstrate that qPCR is more sensitive than other PCR methods along with being reliable for early diagnosis.
