MEANS, METHOD FOR PRODUCING THE SAME AND METHOD FOR CONTROLLING OF DIFFICULT-TO-ERADICATE QUARANTINE WEEDS SUCH AS RUSSIAN CENTAURY USING THE SAME MEANS Russian patent published in 2007 - IPC A01N41/10 A01N31/02 A01P13/00 

FIELD: agriculture.

SUBSTANCE: means for controlling difficult-to eradicate quarantine weeds such as Russian centaury contains herbicide mixture: 2-ethylhexyl ester plus cinydon-ethyl 0.6-1.8 l; metsulfuron-methyl 0.005-0.010 kg; water 100-180 l. Method for producing of said means involves sequentially introducing mother liquors of herbicides into water and mixing during 20 min. Method for controlling of Russian centaury involves treating bunches of Russian centaury with mixture of herbicides: 2-ethylhexyl ester plus cinydon-ethyl 1.2-1.8 l; metsulfuron-methyl 0.008-0.010 kg; water 100-150 l; providing said treatment during budding-blooming period at the rate of 100-150 l/hectare with fallow or half-fallow tillage of soil. Method for controlling of Russian centaury in cereal crop seedlings, said weeds withstanding said herbicides, involves treating bunches of Russian centaury with mixture of herbicides: 2-ethylhexyl ester plus cinydon-ethyl 0.6-0.8 l; metsulfuron-methyl 0.005-0.008 kg; water 150-180 l; treating bunches of Russian centaury in cereal crop seedlings during tillering period at the rate of 150-180 l/hectare.

EFFECT: increased efficiency in killing of weeds.
