| Field trials on weed control in direct seeding with the use of natural phytotoxic ingredients (NPI) were carried out from 2011 to 2013 at the Agricultural Research Institute of Paraná state, Brazil (IAPAR). Soybean was direct seeded into residues of precrop black oats (\textit{Avena strigosa)}. In a split-plot trial the whole-plot treatment consisted of two different weed densities. In the eight subplot treatments the effects of "natural phytotoxic ingredients" (NPI) on weed control was evaluated. The two NPI formulations used in the experiment contained 50 L/ha Pine Oil (formulation ``Pine Oil'') or 50 L/ha d-Limonene (formulation ``Limonene''), both combined with 50 kg/ha NaCl. These formulations were applied once, twice, or three times in a weekly... |
