Isiphetho semvelo sokuvikelwa kwezitshalo ngamakhemikhali sifundwe kabanzi ezindaweni ezipholile, kodwa hhayi ezindaweni ezishisayo.E-Colombia, utamatisi uyimpahla ebalulekile ebonakala ngokusetshenziswa ngokweqile kwemikhiqizo yokuvikela izitshalo ngamakhemikhali.Kodwa-ke, isiphetho semvelo semikhiqizo yokuvikela izitshalo ngamakhemikhali asikakanqunywa.Ngokuthatha amasampula ensimu ngqo kanye nokuhlaziywa kwaselabhorethri okwalandela, kwahlaziywa izinsalela zemikhiqizo engu-30 yokuvikela izitshalo ezitshalweni, amaqabunga namasampula enhlabathi, kanye nezinsalela zezibulala-zinambuzane ezingama-490 emanzini kanye nenzika ezindaweni ezimbili zokukhiqiza utamatisi ezivulekile emoyeni kanye ne-greenhouse.Nge-chromatography ewuketshezi noma i-chromatography yegesi ehlanganiswe ne-mass spectrometry.
Kutholwe imikhiqizo engama-22 yokuvikela izitshalo.Phakathi kwazo, okuqukethwe okuphezulu kwe-thiabendazole ezithelweni (0.79 mg kg -1), indoxacarb (24.81 mg kg -1) emaqabunga, kanye nebhungane enhlabathini (44.45 mg kg) -1) Ukuhlushwa okuphezulu kakhulu.Azikho izinsalela ezitholakele emanzini noma enzikeni.Okungenani umkhiqizo owodwa wokuvikela isitshalo utholwe kumasampula angama-66.7%.Ezithelweni, amaqabunga kanye nomhlabathi walezi zifunda ezimbili, i-methyl beetothrin ne-beetothrin zivamile.Ngaphezu kwalokho, imikhiqizo eyisikhombisa yokuvikela izitshalo yamakhemikhali idlule ama-MRL.Imiphumela yabonisa ukuthi izindawo zemvelo zezindawo ezikhiqiza kakhulu utamatisi wase-Andean, ikakhulukazi emhlabathini kanye nezinhlelo zokukhiqiza ezivulekile, zinobukhona obuphezulu kanye nokuhlobana kwemikhiqizo yokuvikela izitshalo zamakhemikhali.
