Effect of irrigation and soil adjuvant on the efficacy and selectivity of pendimethalin and metazachlor in kohlrabi
Original language description
Precipitation and irrigation strongly affect herbicide management of vegetables, especial fast- growing vegetables as a kohlrabi. The objective of this study was to compare the effects of irrigation and paraffin oil-based soil adjuvant on the efficacy and selectivity of pendimethalin and metazachlor herbicides and their tank-mix combination in kohlrabi. Small plot experiments were carried out in Prague, Czech Republic during 2015 and 2016. Herbicide efficacy on Chenopodium album, Mercurialis annua, and Solanum physalifolium was significantly affected by irrigation shortly after herbicide application, but the efficacy, visual phytotoxicity, as well as both aboveground and root kohlrabi biomass were not affected by the adjuvant. Pendimethalin caused significantly greater phytotoxicity than did metazachlor. Aboveground biomass of kohlrabi plants treated with pendimethalin was about 20-50% less compared to that of plants grown on hand-weeded plots, similar as a tuber yield (tuber weight was about 30% low
