iprodione, fluoxastrobin, pyraclostrobin,
azoxystrobin, trifloxystrobin,
dinotefuran,
imidacloprid,
acetamiprid,
thiamethoxam,
nitenpyram,
clothianidin,
spirotetramat,
chlorpyrifos,
carbosulfan and ethiprole or compositions of more than one type of the
metalaxyl-M, the
fludioxonil, the
prochloraz, the hymexazol, the silthiopham, the ipconazole, the triticonazole, the triadimenol, the diniconazole, the efficient diniconazole, the triflumizole, the metconazole, the
