Experiments were carried out to evaluate the toxicity of six botanicals, Bazna (Zanthoxylum rhetsa), Ghora-neem (Melia sempervirens), Hijal (Barringtonia acutangula), Karanja (Pongamia pinnata), Mahogoni (Swietenia mahagoni) and Neem (Azadirachta indica) against red flour beetle, Tribolium castaneum Herbst. Leaf and seed extracts were prepared by using acetone, methanol and water as solvents. T...

A field plots experiment was carried to investigate the influence of soil applications of neem-based (Achook and Nimbidin) and crop fertilizer (urea and cattle manure) treatments, separately and in combination on free-living and plant-pathogenic nematode populations and crop productivity. Data regarding the results showed that all the treatments significantly decreased the number of plant-paras...

Cost and limited reserves of conventional fossil fuels have intensified the search for alternative fuels for use in internal combustion engines. A possible alternative engine fuel is vegetable oil because it is a clean burning, renewable, non-toxic, biodegradable and environmentally friendly transportation fuel. It can be used in a neat form without any modification of the engine. Vegetable oil...

In a pot experiment, BAU-Biofungicide (Trichoderma harzianum) neem oil and curaterr (carbofuran) 5G were tested against root-knot (Meloidogyne javanica) of two papaya varieties Kashempuri and Deshi papaya. Seedlings were inoculated with second stage larvae of M. javanica. Neem oil (5 ml/ 10g seeds) and BAU-Biofungicide (1:4) were used as seed treatant and curaterr as side dressing. Both the bio...

A laboratory experiment was conducted to investigate the efficacy of different plant derivatives against the development of the cowpea weevil, Callosobruchus maculatus (F) (Coleoptera: Bruchidae) fed on cowpea, Vigna unguiculata (W) seeds. The leaf extracts of romatic plants, Murraya koenigii and Azadirachta indica (A.Juss) were evaluated for their growth, adult mortality and oviposition inhibi...

By C. D. TIWARI. m.b., U.S., u.p.h., and R. B. LAL, M.B., B.S., D.P.H., D.T.M. & H. (From the Epidemiological Bureau, Punjab, Lahore.) While conducting some experiments on disinfestation of houses by fumigation with substances like cresol it was found that the fleas in the rat-holes were not killed and the rats were not at all affected. It would, therefore, seem reasonable that the rat burrows ...

The National Research Institutes’ 1992 report on neem anticipated that continuing research into the components of a tree known in India as a ―village pharmacy‖ would demonstrate useful cures for various ailments, but it’s unlikely that even the most optimistic researcher could have predicted the potentially life-saving treatments being identified now for preventing or treating multiple types ca...

The paper presents an account of a ®eld plot experiment to investigate the in ̄uence of soil applications of neem-based (Achook and Suneem G) and crop fertilizer (urea and cattle manure) treatments, separately and in combination on free-living, and plant-pathogenic nematode populations and crop productivity. All the treatments signi®cantly decreased the number of plant-parasitic nematodes with i...

Malaria is a major public health problem in the world because it can cause of death in patients. Malaria-associated renal injury is associated with 45% of mortality in adult patients hospitalized with severe form of the disease. Therefore, new plant extracts to protect against renal injury induced by malaria infection are urgently needed. In this study, we investigated the protective effect of ...

The control of Lepidoptera pests should be carried out before hatching of their caterpillars to avoid damage to the crops. The aim of this work was to assess the activity of neem (trade name: Natuneem, producer: Base Fértil, Chapadão do Sul, Brazil) and pyroligneous extracts (trade name: Biopirol 7M, producer: Biocarbo, Itabirito, Brazil) at 10 mL/L (1%) and 20 mL/L (2%) contents on egg masses ...
