“…Through the 1700s, preparations of V. album root and rhizomes were used medicinally in Europe primarily for their emetic properties (Chandler and McDougal, 2014). In the folk medicine V. album is used to treat rheumatism, toothache, gout, herpes, trigeminal neuralgia, and catarrh, and as an hypotensive agent (Furbee, 2009;Ujvaŕy, 2010;Wiart, 2012;Roberts and Wink, 2013).…”

The cross-compliance mechanism of the European Union (EU)'s common agricultural policy (CAP) makes the approval of the direct payments to the European farmers subject to compliance with the requirement to maintain the land in good agricultural and environmental condition. One of the obligations of the Romanian land owners and farmers is to avoid the installation of unwanted vegetation on their land plots. This vegetation is represented by some species of herbaceous or woody plants, annual or perennial, that spontaneously invade the agricultural lands, diminishing the production capacity of the cultivated plants. Included in this category are 10 meadow weeds, without fodder value or even toxic to animals: Arctium lappa L., Carduus nutans L., Conium maculatum L., Eryngium campestre L., Euphorbia cyparissias L., Pteridium aquilinum (L.) Kuhn, Rumex acetosella L., Veratrum album L., Xanthium spinosum L., and Xanthium strumarium L. Various and multiple uses in traditional medicine of these meadow weed species have been reported for Romania and other nine neighboring East European countries, i.e.

“…Interaction of nicotine with nicotinic receptors produces initial stimulation followed by protracted depolarization, which results in receptor paralysis. Nicotine has a high acute toxicity in vertebrates, with LD 50 s usually below 50 mg/kg (56). Signs and symptoms of poisoning include nausea, vomiting, muscle weakness, respiratory effects, headache, lethargy, and tachycardia.…”

Pesticides are substances widely used to control unwanted pests such as insects, weeds, fungi and rodents. Most pesticides are not highly selective, and are also toxic to nontarget species, including humans. A number of pesticides can cause neurotoxicity. Insecticides, which kill insects by targeting their nervous system, have neurotoxic effect in mammals as well. This family of chemicals comprises the organophosphates, the carbamates, the pyrethroids, the organochlorines, and other compounds. Insecticides interfere with chemical neurotransmission or ion channels, and usually cause reversible neurotoxic effects, that could nevertheless be lethal. Some herbicides and fungicides have also been shown to possess neurotoxic properties. The effects of pesticides on the nervous system may be involved in their acute toxicity, as in case of most insecticides, or may contribute to chronic neurodegenerative disorders, most notably Parkinson's disease. This brief review highlights some of the main neurotoxic pesticides, their effects, and mechanisms of action.

“…Natural products with pesticidal effects have been in the control of weeds, plant diseases and pests since ancient times (Isman 1997;Ujváry 2001). One of these plant-based insecticides is the compound derived from various parts of Azadirachta indica A. Juss (Meliaceae), also known as neem.…”

The study investigated the effect of soil application of neem at different concentrations on lifetable parameters of Myzus persicae (Sulzer) (Hemiptera: Aphididae). After pepper seedlings were transplanted to pots of 1.5 L, the pepper plants had been divided into five different groups to be watered with only irrigation water (as control) and irrigation water containing 250, 500, 750 and 1000 mg L-1 of neem. Based on the results, intrinsic rate of increase (r m), net production rate (R 0) and mean generation time (T 0) ranged from 0.039 to 0.352 female/female/day, 1.700 to 57.295 female/female and 11.503 to 15.086 days respectively. Doubling time (T 2) and finite rate of increment (λ) ranged from 1.970 to 17.915 days and 1.039 to 1.422 individual/female/day, respectively. Consequently, the effect of neem on biological characters of the pest was increased in response to the increase in neem concentration applied systemically through plant root.
