However, that is debatable.<br> The mode of action of the majority of synergists is to block the metabolic systems that would otherwise break down insecticide molecules.<br> They interfere with the detoxication of insecticides through their action on polysubstrate monooxygenases (PSMOs) and other enzyme systems.<br> The role of synergists in resistance management is an enzyme-inhibiting action.<br> Synergists are tools for overcoming metabolic resistance, and can also delay the manifestation of resistance.<br> Synergist prevent the breakdown of insecticides by the insect’s mixed function oxidase (MFO) system so that the toxic action of the insecticide will be more effective. Terminal enzyme is cytochrome P-450<br> Type of Synetrgists<br><br> PBO (piperonyl butoxide) discovered in 1947 using naturally-occurring safrole as a key raw material.<br> MGK 264 (n-octyl bicycloheptene dicarboximide) prevent the breakdown of insecticides by the insect’s mixed function oxidase (MFO) system so that the toxic action of the insecticide will be more effective.
