I-Chlorothalonil(2,4,5,6-tetrachloroisophthalonitrile) iyinhlanganisela yemvelo esetshenziswa kakhulu njenge-spectrum ebanzi, isibulala-sikhunta esingezona e-systemic, kanye nokunye ukusetshenziswa njengesivikelo sezinkuni, isibulala-zinambuzane, i-acaricide, kanye nokulawula isikhunta, isikhutha, amagciwane, ulwelwe. Iwumuthi ovikela isikhunta, futhi uhlasela isimiso sezinzwa zezinambuzane nezibungu, okubangela ukukhubazeka emahoreni ambalwa. Ukukhubazeka akukwazi ukuhlehliswa.
