Abstract

The introduction of a new and operational system to control weed which can improve application flexibility and control troublesome and stubborn weeds in sugar beet crop. A field study was designed to evaluate the combination of chemical and non-chemical management on cuscuta infestation in sugar beet field. Delaying sowing until the April 18 altered fresh weight of sugar beet 46.1 and 34.9% in the same seedbed preparation in autumn and spring, respectively. Also, application of pyropyzamide herbicide caused the significant difference and greater decrease in weight of cuscuta weed in comparison to another herbicide, ethofumesat. Spring seedbed preparation was more efficient in suppressing and inhibition of cuscuta weed growth than winter seedbed preparation. The concentration of recommended herbicide+25% more treatment showed severity control of cuscuta weed. So, sustainable management of cuscuta inhibition will require a combination of chemical and cultural approaches, supported by understanding the complicated and unclear nature of cuscuta life cycle.
