Abstract
An emulsifiable concentrate formulation for the protection of agricultural crops comprising: (A) a succinate dehydrogenase inhibitor (SDHI) and (B) a phosphoric ester of the formula (R1O)(R2O)(R3O)P═O, wherein R1 represents alkyl having 4 to 12 carbon atoms, or optionally substituted phenyl, and R2 and R3 independently represent alkyl having 2 to 8 carbon atoms, or optionally substituted phenyl. The composition may also comprise surfactants and/or emulsifiers, optionally additional solvents such as esters or amides, and/or an additional fungicide.
