Influence of Nicotine Released in Soils to the Growth of Subsequent Maize Crop, Soil Bacteria and Fung
(International Journal of Agriculture and Biology, 2019)
Nicotine is a major secondary metabolite of tobacco plant. Nicotine is secreted from the tobacco plant roots, while it is stored
in leaf vacuoles. However, some amount of nicotine is released to the soil environment ...
Dynamics of nicotine across the soil–tobacco plant interface is dependent on agro-ecology, nitrogen source, and rooting depth
(Elsevier, 2019-12)
Tobacco (Nicotiana tabacum L.) is the primary nicotine producing plant through its root system (Steppuhn et al., 2004; Shoji et al., 2008). It produces nicotine to as high as 4% of its leaf content compared with potato, ...

Tuta absoluta (Meyrick) is a destructive pest causing adverse environmental and economic effects globally. Management of T. absoluta by synthetic chemicals is of diminutive achievement due to resistance trick of the pest. ...
Multiple ecosystem services from field margin vegetation for ecological sustainability in agriculture: scientific evidence and knowledge gaps.
(PubMed, 2019-11-28)
Background Field margin and non-crop vegetation in agricultural systems are potential ecosystem services providers because they offer semi-natural habitats for both below and above ground animal groups such as soil organisms, ...
Phytochemical Analysis of across East Africa Reveals Three Chemotypes that Influence Its Use as a Pesticidal Plant.
(MDPI, 2019-12-12)
is a plant species chemically characterized by the presence of entomotoxic rotenoids and used widely across Africa as a botanical pesticide. Phytochemical analysis was conducted to establish the presence and abundance of ...
