Mankhwala atsopano ophera tizilombo monga Isofetamid, temotrione ndi resveratrol adzalembetsedwa m'dziko langa.

Pa Novembala 30, bungwe loona za mankhwala ophera tizilombo la Ministry of Agriculture and Rural Affairs (PEsticide Inspection Institute) lalengeza kuti gulu la 13 la mankhwala atsopano ophera tizilombo adzavomerezedwa kuti alembetsedwe mu 2021, ndipo onse ndi mankhwala 13 ophera tizilombo.

Isofetamide:

Nambala ya CAS：875915-78-9

Fomula：C20H25NO3S

Fomula ya kapangidwe kake:

Isofetamide，Imagwiritsidwa ntchito makamaka popewa ndi kuwongolera tizilombo toyambitsa matenda m'mbewu monga zipatso ndi ndiwo zamasamba. Kuyambira mu 2014, Isofetamid yalembetsedwa ku Canada, United States, European Union, Japan, South Korea, Australia ndi mayiko ena ndi madera ena. Isopropyltianil 400g/L yavomerezedwa m'dziko langa popewa ndi kuwongolera nkhungu ya sitiroberi, nkhungu ya tomato, ufa wa nkhaka ndi nkhungu ya nkhaka. Cholinga chake chachikulu ndi soya, nyemba, mbatata, tomato ndi letesi ku Brazil. Kuphatikiza apo, ikulimbikitsidwanso popewa ndi kuwongolera nkhungu ya imvi (Botrytis cinerea) mu anyezi ndi mphesa ndi apple scab (Venturia inaequalis) mu mbewu za apulo.

Tembotrione：

Nambala ya CAS：335104-84-2

Fomula：C17H16CIF3O6S

Fomula ya kapangidwe kake:

Tembotrione：Idalowa pamsika mu 2007 ndipo pakadali pano yalembetsedwa ku Austria, Belgium, France, Germany, Netherlands, Brazil, United States, Mexico, Serbia ndi mayiko ena. Cyclosulfone imatha kuteteza chimanga ku kuwala kwa ultraviolet, imakhala ndi mphamvu zambiri, komanso imagwirizana kwambiri ndi chilengedwe. Itha kugwiritsidwa ntchito poletsa udzu wa gramineous pachaka ndi udzu wa masamba otambalala m'minda ya chimanga. Ma formula omwe adalembetsedwa ndi Jiuyi ndi 8% cyclic sulfone dispersible oil suspension agent ndi cyclic sulfone·atrazine dispersible oil suspension agent, zomwe zonsezi zimagwiritsidwa ntchito poletsa udzu wa pachaka m'minda ya chimanga. 

Resveratrol:

Kuphatikiza apo, mankhwala oyambira a resveratrol 10% ndi yankho losungunuka la resveratrol 0.2% lolembetsedwa ndi Inner Mongolia Qingyuanbao Biotechnology Co., Ltd. ndi zinthu zoyamba kulembetsedwa m'dziko langa. Dzina lonse la mankhwala a resveratrol ndi 3,5,4′-trihydroxystilbene, kapena mwachidule trihydroxystilbene. Resveratrol ndi fungicide yochokera ku zomera. Ndi mankhwala achilengedwe oletsa poizoni m'mera. Mphesa ndi zomera zina zikakhudzidwa ndi matenda monga bowa, resveratrol m'zigawo zofanana zimasonkhana kuti zithetse mavuto. Trihydroxystilbene ikhoza kuchotsedwa ku zomera zomwe zili ndi resveratrol monga Polygonum cuspidatum ndi mphesa, kapena ikhoza kupangidwa mwaluso.

Mayeso oyenerera akuwonetsa kuti madzi a Inner Mongolia Qingyuan Bao 0.2% trihydroxystilbene, omwe ali ndi mphamvu yogwira ntchito ya 2.4 mpaka 3.6 g/hm2, ali ndi mphamvu yolamulira pafupifupi 75% mpaka 80% motsutsana ndi nkhungu ya imvi ya nkhaka. Masabata awiri mutabzala nkhaka, kupopera kuyenera kuyamba musanayambe kapena poyamba matendawo, ndi nthawi ya masiku pafupifupi 7, ndikupopera kawiri.
