Reakcja marchwi i chwastów na chlomazon i jego mieszaninę z pendimetaliną, stosowane z adiuwantem doglebowym Grounded

The experiment was carried out on the experimental field of the National Institute of Horticultural Research in Skierniewice in 2014 to evaluate the biological effect of herbicides on carrot. The following treatments were used: herbicide clomazone (120 g·ha-1) and its mixture with pendimethalin (90 + 999 g·ha-1), used without and with the soil adjuvant Grounded (0.4 l·ha-1). Clomazone with adjuvant was applied at rates of 96 and 120 g·ha-1, and the mixture of clomazone with pendimethalin at rates of 60 + 666 and 90 + 999 g·ha-1. The herbicides were applied directly after the carrot sowing. The experiment assessed weed control, secondary weed infestation as well as growth, development and yielding of carrot. Clomazone and its mixture with pendimethalin, used without and with the soil adjuvant Grounded, effectively reduced weed infestation and did not cause phytotoxicity on carrot plants. The beneficial effects of the soil adjuvant Grounded on the mixture of clomazone and pendimethalin were observed.
