Topramezone: Nzila Iiyandikana Yakubelesya Mubulimi aMakkampani
Zibeela Zipati Zyakubelesya
Mumakwebo aabulimi, topramezone ninzila mpati yakulanganya nsaku zyamazubaano. Ibeleka mbuli chintu chisinkila 4 - hydroxyphenylpyruvate dioxygenase (HPPD) enzyme muzisyango. Kwiinda mukulesya enzyme eeyi iiyandika kapati, ilanyonganya nzila ya carotenoid biosynthesis mumasokwe, akusololela kukusalala kwamatu aayo, kuchedwa kukomena, mpawo kumamanino, lufu. Eeyi nzila ilachita kuti ichite obotu kulwana nsaku zyamisyobo yoonse, kubikkilizya amisyobo myiingi iitakonzyi kulwana misamu iijaya nsaku. Kuzilyo zili mumulongo zilimbuli maila, topramezone ilapa kusala kubotu, ikuzumizya kuti ilwane nsaku kumwi kakwiina ntenda kuchisyango. Ilakonzya kubelesegwa kakutanaba kumena, kuchita kuti kube chisinkilizyo mumuse kuti kutabi kumena kwa nsaku, naakuti nikwamana kumena, kulwana nsaku zikomena loko akucesya kuzundana kwakujana zintu, aboobo kuyaambele loko kuzyala abubotu bwazilyo.
Mumulimo wakupanga misamu, topramezone ibelekela mbuli chintu chiyandikana akati-akati. Bupange bwayo bwamakemikalu bulibedelede bupa kuti ichite lubazu muzintu zisiyene-siyene kuti ipange misamu imwi iiyandikana. Mbuli chitondeezyo, zintu zizwa ku topramezone zilakonzya kuchitwa kuba ma molecule aakatazya kumvwisisisya ajisi nguzu zyakujaya nsaku naakuti milimo imwi iilibedelede. Eezyi zintu zyakabambwa zilakonzya kubelesegwa kutali buyo mumulimo wabulimi pele amuzibeela zimwi mbuli buvwuntauzi akupanga zintu zipya zyakukwabilila zisyango.
Topramezone alimwi ilakonzya kubelesegwa mukupanga nzila zyakulwana nsaku. Mumasena aatalimi mbuli mumasena aakupanga zintu, kumbali aamigwagwa, amumigwagwa yachitima, zipa nzila mbotu yakukwabilila zisyango zitayandiki. Kwiinda mukulesyela kukomena kwa nsaku mumasena aaya, chigwasya kubamba bulondo bwazibelesyo, kuchesya ntenda zyakukwabililwa zijatikizyidwe azisyango zikomena loko, akucesya kuyandika kwakugwisya nsaku amaanza naakuti minchina, kuchitila kuti kutabi chiindi akubeleka.
Nokuba boobo, nikuba kuti topramezone ilaa mpindu zyiingi, ilayandika kweendelezyegwa kabotu. Kweelede kuyobolwa mubusena butontola, butakwe maanzi kule azuba azintu zitali kabotu. Notubelesya topramezone, babelesyi beelede kutobela milawu yakukwabilila, kubikkilizya akusama zizwaato zyakulikwabilila, magilovu, amagilazi, nkaambo zilakonzya kuchisa chikumba ameso. Mukuyungizya, nzila zibotu zyakusowa zintu zitabelesyegwi naakuti zintu zyakupaka zyeelede kutobelwa, kuchitila kutabilila kusofwaazya busena.

Mubufwaafwi
Mukumanizya, topramezone yaba musamu uuyandikana loko mubulimi bwamazubaano amumakwebo aambi. Ikukonzya kwayo kweendelezya nsaku, kubeleka mbuli chintu chipati mukupanga misamu, akupa nzila zyakumanizya nsaku mumafakitali zitondezya mbociyandika. Mbuli tuncini mbobuzumanana kuyaambele, kubelesegwa akugwasya kwa topramezone kulalangilwa kuyaambele, akuyumya busena bwayo mbuli nzila iiyandika kapati yakubelesya misamu.
