- Abstract
Rumex crispus L. is an invasive weed species, widespread in Republic of Bulgaria. Owing to its great reproductive potential and high biological and ecological plasticity, the weed has been assigned to the list of economically most important weeds in the country. With the purpose of studying the possibility of weed control in non-cropped areas with heavy natural background infestation with R. crispus a field trials were carried out. Organic herbicide trade product Segador was tested at two doses 5.0 and 8.0% with the addition of the surfactant Silwet L-77 at a dose 0.1 l/ha. It was found that: (1) The degree of infestation with R. crispus in non-cropped areas can be successfully reduced by treatment with Segador (organic fertilizer with a contact herbicide against weeds effect); (2) treatment of R. crispus with trade product Segador must be carried with a 8.0% solution at early growth stages (BBCH 12-14) by the development of weeds; (3) twenty-one days after application with Segador (applicated as 8.0% solution) efficacy of the product ranges from 97.5 to 100% and there was only 7.8 - 9.1% regeneration of R. crispus The addition of a surfactant Silwet L-77 at a dose of 0.1 l/ha increases the efficiency of trade product Segador.
