An experiment was conducted to investigate the insecticidal activities of seven plant materials (1-5g/100g cowpea seeds) namely: citrus peel powder (CPP), Acacia leaf powder (ALP), Occimum leaf powder (OLP), mahogany bark powder (MBP), hot pepper powder (HPP), ginger powder (GP) and mahogany wood ash (MWA) and a synthetic insecticide, pirimiphos-methyl dust (PMD) (0.1-0.5g/100g cowpea seeds) as...

Objective: The objective of the present study was to evaluate the acute and sub-acute toxicity profile of ethanolic extracts of Punica granatum (L).whole fruit (EPWF) and seeds (EPS) and synthetic ellagic acid (EA) in Swiss albino mice following OECD guidelines. Methods: In acute toxicity study, mice were orally administered 2000 mg/kg body weight of extracts and synthetic compound. In subacute...

I t has been known for over twenty years that the feeding of sweet pea (Lathyrus odoratus) seeds to rats causes skeletal deformities (osteolathyrism) (1). Recently, Ponseti and co-workers (2) have revived interest in the experimental disease of osteolathyrism (or odoratism as it is sometimes called). The condition is characterised by severe and dramatic changes induced in the mesenchymal tissue...

Hexane, chloroform, ethyl acetate and methanol extracts of Strychnos nux-vomica Linn. (Family: Loganiaceae) and Semecarpus anacardium Linn. (Family: Anacardiaceae) were incorporated in semi-synthetic diet at 0.5, 1.0, 1.5 and 2% concentrations. Screened for antifeedant, larvicidal, pupicidal and adult malformation activities against Helicoverpa armigera (Lepidoptera: Noctuidae). The chloroform ...

Screen house trials consisting five plant extracts including a synthetic fungicide (Azadirachta indica, Jatropha curcas Linn., Alium sativum, Ocimum gratissimum, Chromolaena odorata and Benlate ) were tested at the Taraba State University(TSU) Research Farm centre (Ardokoa: Latitude 08 0 53′N and Longitude 11 0 19′E) in a completely randomized design arrangement. The results of the screen house...

A generic sample normalization method applicable in relative comparison of mRNAs quantified with real-time polymerase chain reaction (PCR) is proposed. The method was applied in samples obtained from tomato seeds after osmopriming and aging treatments and from untreated seeds at early imbibition stage, when seeds had not completed germination. Normalization in sample variations was accomplished...

The presence of synthetic dyes in textile wastewater is a problematic issue for environmentalist. Nowadays, dye removal is practiced via different methods. Among all these methods, biodecolorization is an ideal technique. The present research apples vermicompost microflora to remove reactive black- C, pH = 7, and under anaerobic condition. At 36h, removal efficiencies of 94.79%, 94.06%, and 93....

Groundnut is susceptible to a range of diseases and pests owing to its narrow genetic base. Closely related wild relatives of groundnut are diploid, and crossability between diploid wild relatives and tetraploid cultivated groundnut is difficult. Amphidiploid and autotetraploid groundnuts, which are tetraploids (also called synthetic groundnut), were developed at ICRISAT. Crossability between c...

considering the possibility of the harmful side effects of synthetic antioxidants, it is necessary to substitute the synthetic antioxidants by the natural ones, the antioxidants that have been consumed by man for years. the mango seeds were washed and air dried and the kernels were removed manually from the seeds. mango seed kernel oil was extracted by hexane using soxhlet extraction apparatus....
