Abstract

The current invention provides a kit of parts for producing an emulsifiable pesticide solution comprising: (a) a water miscible organic solvent selected from the list of a glycol ether, a glycerol formal, dimethylsulfoxide, gamma-butyrolactone or mixtures thereof, (b) an alkoxylated alcohol with an average of 6 to 80 moles of ethylene oxide and 2 to 60 moles of propylene oxide per mole of alcohol; and (c) a pesticidal active ingredient. The invention further provides a composition for producing an emulsifiable pesticide solution, a method for producing such a composition and a method for treating an agricultural crop. In addition the invention provides some advantageous pesticidal compositions.
