Ngokusho kwewebhusayithi yaseChina yeWorld Agrochemical Network,ama-oligosaccharinsama-polysaccharides emvelo akhishwa emagobolondweni ezinto eziphilayo zasolwandle. Zingaphansi kwesigaba se-biopesticides futhi zinezinzuzo zokuvikela okuluhlaza kanye nemvelo. Ingasetshenziselwa ukuvimbela nokulawula izifo ezihlukahlukene zezitshalo ezifana nezithelo nemifino, ugwayi, nemithi yendabuko yamaShayina, futhi inconywa kakhulu emakethe. Eminyakeni yamuva, izinkampani eziningi bezihlela ukubhaliswa kwemikhiqizo ezungeze ama-oligosaccharins.
Ngokusho kwe-China Pesticide Information Network, okwamanje kunemikhiqizo ebhalisiwe ye-oligosaccharin engu-115, kuhlanganise nama-ejenti axubile angu-45, ama-ejenti angashadile angama-66, kanye nezidakamizwa ezi-4 zoqobo/umama. Kunezinhlobo ezingu-12 zokwakheka ezihilelekile, ngokubhaliswa okuphezulu kakhulu kokwakheka kwamanzi, okulandelwa ukwakheka okuncibilikayo, ukumiswa okungu-13, nokunye okungaphansi kuka-10.
Ama-oligosaccharinsbabe nenani eliphakeme kakhulu lemikhiqizo exutshwe ne-thiazolidines, isamba esingu-10. Kunemikhiqizo engu-4 exutshwe ne-chloramphenicol, imikhiqizo engu-3 exutshwe ne-pyrazolate ne-morpholine guanidine hydrochloride, imikhiqizo engu-2 exutshwe ne-24 epibrassinolide, i-quinoline copper, ne-thiafuramide, kanye nomkhiqizo owodwa kuphela ezinye izingxenye ezingama-21.
Imikhiqizo ye-oligosaccharin eyodwa exubile ingasetshenziswa ukuvimbela nokulawula izifo ezihlukahlukene zezitshalo, phakathi kwazo isifo segciwane likagwayi sinezinga eliphezulu lokubhalisa lama-30, kulandelwa isifo se-tomato virus kanye nesifo se-blight sekwephuzile. Kunemikhiqizo engu-12 yokulawula i-cucumber root knot nematodes, imikhiqizo engu-10 yokulawula isifo se-rice blast, futhi isibalo sezinye izitshalo nezinto zokulawula ezibhalisiwe zingaphansi kuka-10. Kukhona futhi izitshalo ezingu-31 nezinto zokulawula ezibhaliswe no-1 kuphela.
Kafushane, ama-oligosaccharin anokukhethwa okuphezulu kokuxuba,ububanzi bokuvimbela nokulawula, futhi inganciphisa imali yokubhalisa nemijikelezo ngokunciphisa izinto zokubhalisa eziyinsalela nokufaka izicelo zamashaneli okubhalisa aluhlaza.
