| Summary: | Abstract. . The research was conducted during 2013 – 2015 on pellic vertisol soil type. Under investigation was Bulgarian coriander cultivar Lozen 1
(Coriandrum sativum L.). The purpose of the investigation was to establish the selectivity and stability of some herbicides, herbicide combinations and
herbicide tank mixtures on the coriander. Factor A included the years of investigation. Factor B included no treated check, 6 soil-applied herbicides – Tendar EC,
Silba SC, Sharpen 33 EC, Merlin flex 480 SC, Smerch 24 ЕC, Raft 400 SC and 5 foliar-applied herbicides – Kalin flo, Eclipse 70 DWG, Sultan 500 SC, Corrida
75 DWG, Lontrel 300 EC. Factor C included no treated check and 1 antigraminaceous herbicide – Tiger platinium 5 EC. Soil-applied herbicides were treated
during the period after sowing before emergence. Foliar-applied herbicides were treated during rosette stage of the coriander. It is found that tank mixtures of
Tiger platinum with foliar herbicides Kalin flo, Eclipse, Sultan, Corrida and Lontrel lead to obtaining of high seed yields. High yields of coriander seeds also are
obtained by foliar treatment with antigraminaceous herbicide Tiger platinum after soil-applied herbicides Raft, Smerch, Sharpen, Silba and Tendar. The use of
the soil-applied herbicide Merlin flex does not increase the seed yield, due to its higher phytotoxicity on coriander. The most unstable are herbicide Merlin flex
and herbicide combination Merlin flex + Tiger platinum. Technologically the most valuable are herbicide combination Raft + Tiger platinum and herbicide tankmixture
Kalin flo + Tiger platinum. Self-use of soil-applied or foliar-applied herbicides have low estimate due to they must to combine for full control of weeds in
coriander crops. |
