Chidule cha kulembetsa kwa oligosaccharins, mankhwala ophera tizilombo obiriwira

Malinga ndi tsamba lawebusayiti la ku China la World Agrochemical Network,oligosaccharinsNdi ma polysaccharide achilengedwe otengedwa m'zipolopolo za zamoyo zam'madzi. Ali m'gulu la mankhwala ophera tizilombo toyambitsa matenda ndipo ali ndi ubwino woteteza zobiriwira komanso zachilengedwe. Angagwiritsidwe ntchito popewa ndi kulamulira matenda osiyanasiyana a mbewu monga zipatso ndi ndiwo zamasamba, fodya, ndi mankhwala achikhalidwe aku China, ndipo amatamandidwa kwambiri pamsika. M'zaka zaposachedwa, makampani ambiri akhala akukonzekera kulembetsa mankhwala mozungulira oligosaccharins.

Malinga ndi China Pesticide Information Network, pakadali pano pali mankhwala olembetsedwa 115 a oligosaccharins, kuphatikizapo mankhwala osakaniza 45, mankhwala amodzi 66, ndi mankhwala oyamba/a mayi 4. Pali mitundu 12 ya mankhwala omwe akukhudzidwa, omwe ali ndi kulembetsa kwakukulu kwa mankhwala amadzimadzi, kutsatiridwa ndi mankhwala osungunuka, mankhwala osungunuka 13, ndi mankhwala ena osakwana 10.

OligosaccharinsAli ndi mankhwala osakaniza ambiri okhala ndi thiazolidines, okwana 10. Pali mankhwala 4 osakaniza ndi chloramphenicol, mankhwala 3 osakaniza ndi pyrazolate ndi morpholine guanidine hydrochloride, mankhwala 2 osakaniza ndi epibrassinolide 24, quinoline copper, ndi thiafuramide, ndipo ndi mankhwala amodzi okha osakaniza ndi zinthu zina 21.

Mankhwala osakaniza a Oligosaccharins angagwiritsidwe ntchito popewa ndikuwongolera matenda osiyanasiyana a mbewu, omwe matenda a kachilombo ka fodya ali ndi chiwerengero chachikulu kwambiri cholembetsa cha 30, kutsatiridwa ndi matenda a kachilombo ka tomato ndi matenda a late blight. Pali mankhwala 12 oletsa nematode a mizu ya nkhaka, mankhwala 10 oletsa matenda a mpunga, ndipo chiwerengero cha mbewu zina ndi zinthu zoletsa zomwe zalembedwa ndi zosakwana 10. Palinso mbewu 31 ndi zinthu zoletsa zomwe zalembedwa ndi chimodzi chokha.

Mwachidule, oligosaccharins ali ndi kusankha kwakukulu kosakaniza,magulu osiyanasiyana oletsa ndi kulamulira, ndipo akhoza kuchepetsa ndalama zolembetsa ndi nthawi yolembetsa mwa kuchepetsa zinthu zotsalira zolembetsa ndikufunsira njira zolembetsera zobiriwira.
