“…It is worth to mention that T. indica is capable of being transmitted through seeds, soil, and air, making it particularly challenging to control and manage (Kaur and Kaur, 2005;Carris et al, 2006;Kashyap et al, 2019;Bishnoi et al, 2020). Several disease management options are available, including prophylactic measures, fungicide sprays, and deploying partially resistant wheat cultivars (Emebiri et al, 2021;Kashyap et al, 2022a;Singh et al, 2023b). However, these measures may not be entirely effective, especially under high disease pressure (Goates and Jackson, 2006;Bala et al, 2022).…”

The current study describes a new diagnostic method for the rapid and accurate detection of Tilletia indica, the pathogen accountable for causing Karnal bunt (KB) disease in wheat. This method uses quantitative real-time polymerase chain reaction (qPCR) and a primer set derived from glyceraldehyde 3-phosphate dehydrogenase (GAPDH) gene of T. indica to identify the presence of the pathogen. The qPCR assay using this primer set was found highly sensitive, with a limit of detection (LOD) value of 4 pg of T. indica DNA. This level of sensitivity allows for the detection of the pathogen even in cases of different growth stages of wheat, where no visible symptoms of infection on the wheat plants can be seen by naked eyes. The study also validated the qPCR assay on ten different wheat cultivars. Overall, this study presents a valuable molecular tool for rapid, specific and sensitive detection of KB fungus in wheat host. This method has practical applications in disease management, screening of wheat genotypes against KB and can aid in the development of strategies to mitigate the impact of Karnal bunt disease on wheat production.

“…Nanotechnology is a branch of science which deals with the synthesis and application of nano particles having size 1-100 nm ( Jasrotia et al, 2018;Roco 2003). Now a days, nanotechnology is emerging as a promising approach to be incorporated in agriculture to improve productivity of different crops through seed treatment with nano particles, their foliar spray on plants, nano-fertilizers for balanced crop nutrition, nanoherbicides for effective weed control, nano-insecticides for plant protection, early detection of plant diseases and nutrient deficiencies using diagnostics kits and nanopheromones for effective monitoring of pests (Kashyap et al, 2022;Singh et al, 2021). Zinc is essential for plant's enzyme system as it acts as cofactors, metal components and other regulatory factors of many enzymes (Kushwaha et al, 2021;Prasad et al, 2012) which comes in the fourth position after nitrogen, phosphorous and potassium.…”

The study was conducted on six barley varieties viz. BH 885, BH 946, BH 393, BH 902, DWRB 92 and DWRB 101 at CCS HAU, Hisar during 2020-21. The results revealed that maximum catalase activity (243.168 and 157.981umoles/g FW), peroxidase activity (22.33 and 35.03 units/g FW), superoxide activity (22.03 and 35.03 nmoles/g FW) and dehydrogenase activity (0.213 and 0.245 OD/g/ml) were estimated in the seeds primed with ZnO NPs @ 100ppm in cloth and polythene bag, respectively in variety DWRB 92. Among the varieties, DWRB 92 recorded highest catalase activity (217.168 umoles/g FW) in cloth bag while BH 393 recorded maximum catalase activity (232.961 umoles/g FW) in polythene bag. Minimum catalase activity was observed in DWRB 101(60.351 umoles/g FW) in cloth and BH 885 recorded least (121.418 umoles/g FW) in polythene bags. Maximum peroxidase activity (21.22 and 31.56 units/g FW) was estimated in BH 885 while minimum (12.71 and 22.54 units/g FW) in BH 946 in cloth and polythene bag, respectively. Maximum SOD activity (18.033 and 25.033 nmoles/g FW) was measured in DWRB 92 and minimum (12.712 and 22.537 nmoles/g FW) in BH 946 in cloth and polythene bag, respectively. Maximum DHA activity (0.170 and 0.206 OD/g/ml) was recorded in DWRB 101 and least in BH 946 (0.234 and 0.281 OD/g/ml) in cloth and polythene bag. It is concluded that among the various seed priming treatments, priming with ZnO NPs@100ppm at 25°C for 24 hours maintained higher enzyme activity. Barley seed quality can be maintained by storing the seeds at optimum moisture content (<8%) in polythene bags (>700gauge) with germination upto 94.61% as compare to cloth bags (85.89%).

Nanotechnology has emerged as a promising approach for the controlled release of nutrients, particularly phosphorus and potassium. These essential plant nutrients are often applied in excess, leading to environmental pollution and loss of efficiency in crop production. Innovative economic and highly efficient fertilizers are urgently needed to achieve the targeted crop production worldwide in the presence of limited land and water resources. Therefore, in this study, novel, eco-friendly, cost-effective and enhanced efficiency nano-enabled fertilizers, NEF (nWTF1and nWTF2) were synthesized by impregnation of nanostructured water treatment residuals (nWTR) with (KH2PO4 + MgO) at 1:1 and 3:1 (w/w) ratios respectively using a planetary ball mill. The nWTR, nWTF1 and nWTF2 were extensively characterized. The water retention behavior and the sustained release of nutrients from the fabricated nano-enabled fertilizers (nWTF1 and nWTF2) in distilled water and sandy soil were investigated and monitored over time. The water retention capacity of the soil treated with nWTF2 after 26 days was 9.3 times higher than that of soil treated with conventional fertilizer. In addition, the nWTF2 exhibited lower release rates of P, K and Mg nutrients for longer release periods in comparison with the conventional fertilizers. This is a significant advantage over traditional fertilizers, which release nutrients quickly and can lead to leaching and nutrient loss. The main interaction mechanisms of PO4–K–Mg ions with nWTR surface were suggested. The results of the kinetics study revealed that power function was the best suitable model to describe the kinetics of P, K and Mg release data from NEF in water and soil. The produced NEF were applied to Zea maize plants and compared to commercial chemical fertilizer control plants. The obtained results revealed that the nano-enabled fertilizers (nWTF1 and nWTF2) significantly promoted growth, and P content compared with the commercial chemical fertilizer treated plants. The present work demonstrated the power of nano enabled fertilizers as efficient and sustained release nano-fertilizers for sustainable agriculture and pollution free environment.
