The paper and compound are placed in a 30-ml wide-necked bottle and 3 ml of acetone containing 1 Secret 20 (polyoxyethylene sorbitan monolaurate) is added to dissolve the compound. If the substance is insoluble 8-acetone, then another solvent is used instead, such as water, alcohol or dimethylformamide (DMF). If DMF is used, then only 0.5 ml or less is used to dilute the compound, and then another solvent is used to keep the volume up to 3 ml. 3 ml of the solution is uniformly sprayed onto the surface of the soil contained in the small box, one day after sowing the seeds of weeds in the soil of the box. For spraying the liquid, use dry air under a pressure of 0.352 kg / cm. The application dose is 91072 kg / g and the volume of the sprayed liquid is 1353.25 l / ha.
