Herbicide drift vs. crop resilience - the influence of micro-rates

A greenhouse study was conducted to test the effects of low herbicide dose exposure on different crops measuring visible damages, plant height, leaf area, and dry matter. Seven were tested: lettuce (Lactuca sativa L.) cv. Novosadska majska maslena, oil pumpkin (Cucurbita maxima Duch) Olivija, oilseed rape (Brassica napus NS Ras, pepper (Capsicum annuum Kurtovska kapija, soybean (Glycine max (L.)
