Pesticides are formulated in many different ways. Quizalofop-P-ethyl is selective post emergence herbicide which can be found on the market formulated as emulsifiable concentrate (EC) and suspension concentrate (SC). The objective of this investigation was to develop two types of formulations: emulsifiable concentrate (EC) and went a step forward and developed oil in water (EW) formulation. Oil in water (EW) is a kind of pesticide formulation which contains water instead of almost all organic solvents. EW recently replaces EC as a new excellent environmentally-friendly pesticide formulation. We started investigation with development of EC formulation (50 g a.s./L) and after that developed EW formulation with the same concentration of active ingredient. The results obtained by testing developed formulations according to FAO and WHO recommendations shown that they had necessary stability to be applied in plant protection.
