Abstract
The aim was to evaluate reaction of new varieties of sugar maize to a mixture of mesotrione + S-metolachlor. The study was conducted in 2007–2009 in Experimental Station in Swadzim on ten varieties of sugar maize Basin, Dixon, Garrison, Golda, GSS 5022, Rana, Shaker, Shimmer, Sweet Trophy and Sweet Tasty. Herbicide spraying was performed in the 5–6 leaf stage of maize. In each year of research the cob yield (t/ha), cobs from ha (pcs), class participation (%), cobs length (cm) and number of grains in the cobs (pcs) were examined. There was found transient phytotoxic action of the herbicide in three varieties. A mixture of mesotrione + S-metolachlor reduced the yield in eight varieties, I class cobs yield in seven varieties, cobs length in six varieties and the number of cobs per ha in nine varieties, but had no significant effect on the number of grains in cob.
