Complexation of carbendazim with hydroxypropyl-β-cyclodextrin to improve solubility and fungicidal activity

► An inclusion complex between MBC and HPβCD was prepared and characterized. ► By complexation with HPβCD, the water solubility of MBC was improved. ► By complexation with HPβCD, the fungicidal activity of MBC was improved. ► The work provides a approach for a more rational application of MBC.
