Crude and purified extracts of non edible seed.of Pongamia glabra ( Karanja) were tested for their toxicity growth and development against the 2 instar larvae of the American bollworm, Helicoverpa armigera (Hubner) a serious pest of cotton. Larvae reared on synthetic diet at concentrations of 1 and 0.5% of P. glabra exhibited 100% mortality, whereas at sublethal concentrations of 0.05% and 0.01...

BACKGROUND Agricultural products and by products provide the primary materials for a variety of technological applications in diverse industrial sectors. Agro-industrial wastes, such as cotton and curaua fibers, are used to prepare nanofibers for use in thermoplastic films, where they are combined with polymeric matrices, and in biomedical applications such as tissue engineering, amongst other ...

Abstract Declining water levels in the southern Ogallala Aquifer and associated reduction irrigation capacities increasing pumping costs necessitate adoption of deficit/limited practices for sustaining cotton production Texas High Plains (THP) region. The overall goal this study was to evaluate response crop stress different growth stages suggest efficient growth-stage-based deficit (GSBD) sche...

It is often argued that learning from best examples in the neighbouring Burkina Faso and elsewhere, Ghana can succeed in revamping the collapsing cotton industry by introducing Bt cotton to farmers. This paper therefore presents a survey findings on farmers’ views and perceptions towards the possible introduction of Bt cotton. A stratified random sampling techniques was applied in selecting 254...

Cotton fabric was treated with fluorine gas in a nitrogen atmosphere. The effect of fluorination treatments on wettability, whiteness index, dyeability and mechanical properties of cotton fabrics were assessed. Kawabata analysis shows that fluorination treatment increases shear stiffness G, shear hysteresis 2HG5, bending stiffness B and overall fabric stiffness Koshi on cotton fabric. Fluorinat...

BACKGROUND Farm workers and female cotton pickers are exposed to residual impacts of pesticide use in cotton production, in addition to dust, ultraviolet radiation, etc. Cotton picking causes various health hazards among cotton pickers with varied health cost. A soil bacterium known as Bacillus thuringiensis (Bt) is incorporated in cotton seed through genetic modification and it has resistance ...

originally found in Mississippi in 1980 and by 2002 was estimated to infest 32.4% of the cotton hectarage in Cotton (Gossypium hirsutum L.) lint yields have not changed apMississippi (Lawrence et al., 2002). Although genetics preciably during the last decade. Because more and higher infestations is still probably the predominant reason for the lack of of reniform nematodes (Rotylenchulus renifo...
