Glyphosate Phytotoxity to Equisetum arvense as Affected by Growth Stage and Water Stress.

Chemical control of field horsetail (Equisetum arvense)

Field horsetail is a perennial, rhizomatous weed with summer-growing fern-like foliage and sporelating stems. It likes moist, free-draining sandy soils and gravel riverbeds and flood plains. Glasshouse experiments on 10-month old potted field horsetail plants showed excellent efficacy of imazapyr, amitrole, metsulfuron, picloram and combinations of picloram with metsulfuron or triclopyr, all at...

Seed yield and some physiological traits of safflower as affected by water deficit stress

Safflower (Carthamustinctorius L.) is an oilseed crop adapted to drought prone arid and semi-arid environments. This study was conducted to evaluate the effects of water deficit stress on antioxidant activity, membrane stability index (MSI), leaf chlorophyll content, leaf area index (LAI) and their relationship with seed yield using 64 safflower genotypes grown under normal and water defici...

Pearl Millet Growth as Affected by Phosphorus and Water

The interaction of soiil water and P supply is of paramount importance to pearl millet [Penniseturn gluucum (L.) R. Br.] growth in Sahelian Africa due to unreliable rainfall and low soil P availability. This study was conducted to quantify the growth response of pe:ul millet to water supply and P under conditions analogous to the Saliel in terms of climatle and soil. Millet was grown for 84 d i...

Sedative and anticonvulsant effects of hydroalcoholic extract of Equisetum arvense.

The hydroalcoholic extract of Equisetum arvense (HAE) tested at the doses of 200 and 400 mg/kg showed a significant activity on the open-field, enhanced the number of falls in the rota-rod reducing the time of permanence in the bar and increased the sleeping time (46% and 74%) in the barbiturate-induced sleeping time. In the pentylenetetrazole-seizure, it increased the first convulsion latency,...
