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...
متن کاملEstablishing systemic rust infections in Cirsium arvense in the field
An existing method to induce systemic rust infections in creeping thistles (Cirsium arvense) using an insect vector, the weevil Ceratapion onopordi, was successfully applied in the field. Urediniospores of Puccinia punctiformis were experimentally transmitted to naturally grown thistles, to our knowledge for the first time resulting in systemically infected shoots in an established thistle popu...
متن کاملSedative and anticonvulsant effects of hydroalcoholic extract of Equisetum arvense.

In the pentylenetetrazole-seizure, it increased the first convulsion latency,...
متن کاملGibberellins and Light Regulated Petiole Growth in Thlaspi arvense L.
Petiole growth in Thlaspi arvense L. was stimulated when a basic 8 hour photoperiod (4.20 milliwatts per square centimeter) was extended with low intensity light (0.16 milliwatt per square centimeter) from incandescent lamps. The day length extension was effective only when the light contained high proportions of far red light. Exogenous gibberellin A(3) (GA(3)) could partially substitute for t...
