Mechanistic Aspects and Effects of Selected Tank-Mix Partners on Herbicidal Activity of a Novel Fatty Acid Ester

The experimental herbicide was the pelargonic acid ester of methylated polyethylene glycol (PA-MPEG), Two experiments were carried out to check the optimum conditions for the PA-MPEG and Hasten. The first trial was conducted with a factorial arrangement of three Hasten use concentrations (0, 1, 2, and 2.5% v/v), two spray volumes (200 and 400 L ha−1) and a single PA-MPEG concentration of 7.5%. In the second experiment, different PA-MPEG concentrations alone or with 2.5% Hasten were applied at 200 L ha−1.
