Universal zikutanthauza kulamulira namsongole "Roundup": malangizo ntchito

Mankhwala "Roundup" malangizo ntchito limafotokoza monga njira chilengedwe mwapadera kuti thupilo namsongole. Lero ndi mmodzi wa herbicides odziwika bwino kwambiri padziko lonse. Choncho kugwiritsa ntchito "Roundup" kukonzekera bwino pamene dongosolo la mankhwala wotchedwa yopitirira, i.e. mankhwala zomera ikuchitika chisanadze zikamera kapena mwachindunji isanafike yofesa. Kuyenera anatsindika kuti herbicide alibe gawo lirilonse la nthaka, zokhudza okha zanthete ndi masamba. Komanso, ali mmodzi wa mankhwala chabwino kwa anthu ndiponso chilengedwe. Monga kumene kugula "Roundup", koma lero zikutanthauza mugule pafupifupi uliwonse sitolo kupereka mankhwala m'munda.

Yopangidwa yogwira mankhwala mu madzi mawonekedwe, lomwe lili mu kapangidwe kake, glyphosate, kumachita monga pophika yogwira, ndi surfactants wapadera kuti magawowa posungira padziko glyphosate ndi malowedwe bwino mu masamba ndi mphukira. Ichi chimatanthauza zotsatira kuphatikiza a "Roundup" (malangizo Buku akutitsimikizira nkhani imeneyi) mogwira amachita monga mobisa ndipo pamwamba-kuuluka mbali ya zomera, ndi kukwaniritsa okwana kupha dicots udzu, pachaka namsongole osatha.

Pambuyo ntchito mwachindunji yogwira ndi wothandiza zinthu alipo zikuchokera herbicide, pakuti maola anayi sikisi atamezedwa kotheratu zimakhala. Ndiye, patapita masiku awiri, mankhwala "Roundup" (malangizo ntchito zimenezi monga umboni) ndi anagawira mu mizu ya zomera, kusokoneza kaphatikizidwe amino zidulo ndi motero kuchititsa imfa ya mbewu.

Pa nthawi yomweyo zizindikiro loyamba la ntchito ya glyphosate (chikasu ndi wilting masamba) ali kale noticeable atapita masiku asanu ndi khumi pambuyo ntchito herbicide lapansi. Inawonongedwa namsongole pambuyo masabata awiri kapena atatu mankhwala.

Ngati tikambirana mbali yaikulu ya ntchito mankhwala imeneyi, choyamba kudziŵika kuti kupopera bwino mu nyengo bata mu nyengo ya kukula kwambiri kwa zomera. Mvula, amene adatenga maola asanu mankhwala akhoza kwathunthu muzimutsuka mankhwala masamba ndi kuchepetsa zotsatira. Komanso, musakhale mu masiku awiri pambuyo kupopera kugwira tithe kumvetsa kumasulira nthaka, chifukwa pa nthawi imeneyi mizu mkatikati mankhwala "Roundup". Malangizo ntchito likutsindikanso kuti pofuna kupewa chiwonongeko cha mbewu, otsiriza ayenera kuphimba filimu. Komanso, musati ntchito pa opopera ntchito ndi atomization chabwino. Pomaliza, nthawi zonse tiyenera kukumbukira kuti zomera ndi womvera mankhwala "Roundup" mu theka lachiwiri la chilimwe.
