Bio-efficacy of insecticides on six spotted ladybird beetle, Coccinella septempunctata (Linnaeus) in brinjal crop
The coccinellids, Coccinella septempunctata L. is a very important bio-agent against soft bodied insects for many crops. The conservation of this predator in IPM approaches required knowledge of the toxicity and the effectiveness of insecticides on their biological characters. In the present study, the efficacy of the six insecticides (Spinosad 45EC, Emamectin benzoate 5 SG, Indoxacarb 14.5 SC, Quinalphos 25 EC, Profenophos 50 EC and Lambda-cyhalothrin 5EC), one microbial insecticide (Bacillus thuringiensis) and one botanical insecticide (Neem oil 1500ppm) on the mortality, developmental time and consumption These studies were conducted at the Sardar Vallabhbhai Patel University of Agriculture & Technology in Meerut, Uttar Pradesh, India, during the Zaid seasons of the year 2019 and 2020. The pe-treatment and post treatment observations were taken on the basis of population of C. septempunctata present in the brinjal crop. The observations were taken in seventh and fourteenth days after spraying. Data generated in the year 2019 that C. septempunctata population per five plants of brinjal was highest recorded in untreated plot than the plot treated with Bacillus thuriengiensis, which was followed by neem oil treatment i.e. 6.67 (both 7 and 14 Days After Spraying), 4.67 (7 DAS), 4.00 (14 DAS), 4.00 (7DAS) and 3.67 (14DAS), respectively. All new molecules of insecticides were found to be significantly recorded lower population of C. septempunctata. Same observations were also taken in zaid season of year 2020, we observed the same trade as previously recorded in the year 2019.
Integrated approach for weed management in groundnut
Studies conducted at Regional Research Station, Tamil Nadu Agricultural University, Vridhachalam, TamilNadu during rabi/summer 2016-17, 2017-18 and 2018-19 revealed the integration of herbicides with cultural method to contain weeds in groundnut under rice-groundnut system. Among the various herbicides tested, application of Pendimethalin 30% EC @ 1.50 kg a.i/ha followed by (fb) one hand weeding at 25 DAS recorded higher pod yield of 2443 kg/ha over rest of the herbicide combination treatments. The other treatments viz., pendimethalin 30% EC @ 1.5 kg a.i/ha fb Imazethpyr 10% S.L @ 75 g a.i/ha produced pod yield of 2212 kg/ha followed by pendimethalin 30% EC @ 1.50 kg a.i/ha fb quizalopfop ethyl 5 % E.C @ 50 g a.i/ha which gave 2171 kg/ha. All the treatment combinations were found on par with each other and significantly superior over control in terms of pod yield. The weed control efficiency was also higher (91 %) with application of pendimethalin 30% EC @ 1.50 kg a.i/ha fb one hand weeding at 25 DAS. The net return and benefit cost ratio was also higher with the same treatment i.e.application of pendimethalin 30% EC @ 1.50 kg a.i/ha fb one hand weeding at 25 DAS worked out with higher BCR (2.38).
Antioxidant, Anticoagulant, Antithrombotic Activities And Analgesic Effect Of Stem Extracts Of Launaea acanthoclada
Launaea acanthoclada is a medicinal plant used to treat inflammations, digestive disorders and wound infections. The aim of our study was to assess antioxidant, anticoagulant, antithrombotic activities and analgesic effects of this plant extracts. The total phenols and flavonoids content of the different extracts were determined using Folin-Ciocalteu and Aluminum chloride colorimetric assays. Antioxidant activity was performed using several methods. The anticoagulant and antithrombotic activity was tested on human blood. To evaluate analgesic activity, the crude extract was subjected to acetic acid-induced writhing test. Crude extract (CrE) and ethyl acetate extract (EAE) showed a potent activity in scavenging DPPH (IC50 of 9.14 ± 1.88 and 44.3 ± 0.85 µg/mL). EAE, CrE, butanol (BuE) and hexane (HeE) fractions displayed the greater activity (> 80%) in inhibition of β-carotene oxidation. However, EAE had an IC50 of 0.87 ± 0.02 mg/mL in hydroxyl radical scavenging assay. Aqueous fraction (AqE) and EAE showed a significant percentage of clot lysis (35.15 and 30.08%). CrE, HeE and EAE inhibit blood clotting even after 3 h. In addition, CrE induced significant antinociceptive activity of 50 and 57.28% at doses of 150 and 300 mg/Kg, respectively. Our findings revealed that L. acanthoclada could be used in the development of new natural medicines.
Combining Ability Analysis of Quality Protein Maize Inbred lines
The present study was aimed to assess the general combining ability of parents and specific combining ability of their crosses for yield and quality traits. Nine inbred lines were crossed with three testers using line × tester mating design. Nine lines, three testers and 27 F1s were evaluated along with two checks in this study for grain yield per plant, grain protein content, tryptophan content and lysine content during Rabi 2021-22 and Spring 2022. Total 41 genotypes (27 crosses, 9 lines, 3 testers and 2 checks) were evaluated in Randomized Block Design with three replications at experimental farm of BAC, Sabour. Based on general combining ability analysis parents L4, L6, L9 were found as good general combiner for grain yield & quality traits in rabi season. L1, L2 and L3 were accompanied with significant GCA in desired direction for tryptophan and lysine content in spring season. Among the crosses L2 × T1, L7× T3 and L3× T1, L9 × T3 exhibited highly significant and desirable SCA effects for grain yield per plant in rabi and spring season respectively. L3× T3 possessed highly significant SCA effects for protein, tryptophan and lysine content in spring season. Therefore, these crosses can be utilized for developing high yielding good quality hybrid varieties in maize. There was preponderance of non-additive gene action in the inheritance of all the traits.
In silico Prediction of Antiviral Activity of Andrographis paniculata Against NDV2K35 strain of Newcastle Disease Virus
The present study focused on molecular docking analysis of active principles of Andrographis paniculata with NDV2K35 proteins, a strain of Newcastle disease virus. The 3D structures of NDV2K35 proteins (receptors) viz. Haemagglutin-Neuraminidase protein (HN), Fusion protein (F), Matrix protein (M), Phosphoprotein (P), Large polymerase protein (L) and Nucleocapsid protein (N) were downloaded from Uniprot database, modelled using Swiss model analysis and validated by RAMPAGE: Ramachandran plot analysis. The active principles of Andrographis paniculata (ligands) viz. andrographolide, neoandrographolide and 14-deoxyandrographolide were downloaded from PUBCHEM, a database for chemical molecules. The docking analysis was carried out using Accelrys Discovery Studio 4.0 Client software. The results revealed that andrographolide interacted with all except M protein. The dock score of neoandrographolide was more than andrographolide with all the proteins but it failed to interact with F and M protein. The compound 14-deoxyandrographolide interacted with all proteins except F protein but the dock scores were comparatively less. The active principles were further screened for in silico pharmacokinetic and pharmacodynamic properties using Swiss ADME, a standard online tool and PASS online server. The active principles exhibited good GI absorption with bioavailability of 55 % and acted as substrate for p-gp. Of the three, neoandrographolide inhibited CYP3A4 which indicates the possibility for drug interactions. Toxicity analysis showed comparatively higher toxicity for neoandrographolide. Thus, andrographolide can be considered as a better choice for developing antiviral drug against Newcastle disease virus. However, the synergistic effect of all the three may possess better antiviral activity in vivo and needs further study.
