ABSTRACTDormancy is exhibited in many seed producing plants. It could be endogenous or exogenous, depending on the plant and the type of seed the plant produce. A survival strategy, plant use to conserve their genetic materials during unfavourable conditions. Scarification treatments has been used in this work to break the dormancy ofAnacardium occidentale, Annona muricata, Jatropha curcas, Tamarindus indicaandArtocarpus heterophyllususing 65% Nitric acid (HNO3), 65% Sulphuric acid (H2SO4), 0.5% Potassium tetraoxosulphate(VI) (K2SO4), 0.5% Urea (CH4N2O), 43% Ethanol (C2H6O) and Distilled water. Nitric acid (65% HNO3) produced the best result forAnacardium occidentalewith high numbers of seedlings and a germination period of 15 days.Jatropha curcasdid not produce a favourable result from the treatments.Tamarindus indica,water treatment produced the best result with six days of germination shorter than the controlled value (16 days). Nitric acid (65% HNO3) and water favorAnnona muricatawith germination period of 19 days as against 24 days for control experiment. Water and Potassium sulphate are the best treatments forArtocarpus heterophyllusas they produce viable seedlings with short germination period of 14 and 15 days which give a good result better than the 18 days of the control experiment.

Store grain insect pests such as Lesser grain borer (Rhyzopertha dominica) is a key feeder and cause substantial weight loss of wheat during storage. Present study was planned to evaluate insecticidal, repellent and growth regulator potential of botanical extracts of two plants Jatropha curcas and Linum usitatissimum along with Spinetoram against Rhyzopertha Dominica. This study was conducted at the Department of Entomology, University of Agriculture, Faisalabad (UAF) Grain Research, Training, and Storage Management Cell. Each treatment with three replication of 5%, 10%, and 15% concentrations of plant extracts and 100ppm, 200ppm, and 300ppm concentrations of insecticide were used against the adults of R. dominica by using Complete Randomized Design. Insect mortality was taken after 24, 48, and 72 hours after treatment. Data of growth regulation data was observed after 30 and 60 days. Data was analyzed by statistic 8.1 software for analysis of variance at 5% level of significance and treatment means was compared with the help of Tukey's Honestly Significant Difference (THSD) test. After 72 hours, Spinetoram showed maximum percent mortality (84%) followed by J. curcas (19.17%) and L. usitatissimum (12.28%) at their higher concentrations rate. Among treatments, after 60 days of exposure, Spinetoram was proved to be more effective against the R. dominica with maximum growth inhibition (70%) as compared to J. curcas (44%) and Linseed (28%). Overall the results indicated that these plant extracts and Spinetoram can be used as efficient alternatives of synthetic chemicals for management of stored grains insect pests.

Colletotrichum Gloeosporioides Species Complex

A survey was conducted in twenty-five cashew (Anacardium occidentale) orchards in five communities in the Dormaa-Central Municipality of Bono Region of Ghana to assess the incidence and severity of anthracnose, gummosis and die-back diseases on cashew. Cashew diseased samples of leaves, stem, inflorescences, twigs, flowers, nuts and apples showing symptoms (e. g. small, water-soaked, circular or irregular yellow, dark or brown spots or lesions on leaves, fruits and flowers, sunken surface, especially on the apples, blight, gum exudates) were collected for isolation of presumptive causative organism. The pathogen was isolated after disinfecting the excised diseased pieces in 70% ethanol, plated on potato dextrose agar (PDA) and incubated at 28 oC for 3 to 7 days. The identity of the putative pathogen was morphologically and culturally confirmed as belonging to Colletotrichum gloeosporioides species complex using standard mycological identification protocols. The pathogen had varied conidia sizes of between 9-15 up to 20 μm in length and diameter of 3-6 μm. The conidia were straight and cylindrically shaped with rounded or obtuse ends. The septate mycelium was whitish-grey, velvety and cotton-like in appearance from the top. The results confirmed the presence of the pathogen in the orchards with incidence ranging from 6.9% and 14.0% for gummosis and averaged 22.9% for anthracnose infected orchards. The result of the pathogenicity test confirmed the isolates to be pathogenic on inoculated cashew seedlings and were consistently re-isolated, thereby establishing the pathogen as the true causal agent of the said diseases in cashew trees and thus completed the Koch’s postulate.

Plants Extract

The anthelmintic resistance has limited the control of gastrointestinal nematodes of small ruminants and thus has awakened interest in the study of plants extract as a source of anthelmintics. These experiments were carried out to evaluate the in vitro efficacy of Jatrophacurcas latex extract against Haemonchuscontortus larval motility. To evaluate the larvicidal activity, H.contortus L3 were incubated with the extracts with varying concentration of 5 mg/mL, 10 mg/mL, 15 mg/mL and 20 mg/mL at 27°C for 48, 72 and 96 hrs. The results were subjected to the Kruskal-Wallis test (P less than 0.05). The extracts showed dose-dependent larvicidal effects. These results suggest that J.curcas can be used to control gastrointestinal nematodes of small ruminants.

<p>The Severe Acute Respiratory Syndrome 2 (SARS-CoV-2) is an infectious virus that causes mild to severe life-threatening upper respiratory tract infection. The virus emerged in Wuhan, China in 2019, and later spread across the globe. Its genome has been completely sequenced and based on the genomic information, the virus possessed 3C-Like Main Protease (3CLpro), an essential multifunctional enzyme that plays a vital role in the replication and transcription of the virus by cleaving polyprotein at eleven various sites to produce different non-structural proteins. This makes the protein an important target for drug design and discovery. Herein, we analyzed the interaction between the 3CLpro and potential inhibitory compounds identified from the extracts of <i>Zingiber offinale</i> and <i>Anacardium occidentale</i> using in silico docking and Molecular Dynamics (MD) Simulation. The crystal structure of SARS-CoV-2 main protease in complex with 02J (5-Methylisoxazole-3-carboxylic acid) and PEJ (composite ligand) (PDB Code: 6LU7,2.16Å) retrieved from Protein Data Bank (PDB) and subject to structure optimization and energy minimization. A total of twenty-nine compounds were obtained from the extracts of <i>Zingiber offinale </i>and the leaves of <i>Anacardium occidentale. </i>These compounds were screened for physicochemical (Lipinski rule of five, Veber rule, and Egan filter), <i>Pan</i>-Assay Interference Structure (PAINS), and pharmacokinetic properties to determine the Pharmaceutical Active Ingredients (PAIs). Of the 29 compounds, only nineteen (19) possessed drug-likeness properties with efficient oral bioavailability and less toxicity. These compounds subjected to molecular docking analysis to determine their binding energies with the 3CLpro. The result of the analysis indicated that the free binding energies of the compounds ranged between ˗5.08 and -10.24kcal/mol, better than the binding energies of 02j (-4.10kcal/mol) and PJE (-5.07kcal.mol). Six compounds (CID_99615 = -10.24kcal/mol, CID_3981360 = 9.75kcal/mol, CID_9910474 = -9.14kcal/mol, CID_11697907 = -9.10kcal/mol, CID_10503282 = -9.09kcal/mol and CID_620012 = -8.53kcal/mol) with good binding energies further selected and subjected to MD Simulation to determine the stability of the protein-ligand complex. The results of the analysis indicated that all the ligands form stable complexes with the protein, although, CID_9910474 and CID_10503282 had a better stability when compared to other selected phytochemicals (CID_99615, CID_3981360, CID_620012, and CID_11697907). </p>
