Kodi systemic herbicides ndi chiyani?

Zopangira herbicidesndi mankhwala opangidwa kuti achotse udzu mwa kulowetsedwa m'mitsempha ya mmera ndikusuntha chamoyo chonse. Izi zimathandiza kuti udzu uthetsedwe bwino, kulunjika mbali zonse za zomera zapansi ndi pansi.

M’zaulimi wamakono, kaonekedwe ka malo, ndi nkhalango, kuletsa udzu kogwira mtima n’kofunika kwambiri kuti mbewu zisungidwe bwino, kukongola kokongola, ndi nkhalango zathanzi. Mankhwala a herbicides amagwira ntchito yofunika kwambiri m'magawo amenewa popereka njira zothana ndi udzu zogwira mtima komanso zokhalitsa.

Chidule cha Glyphosate Monga Chitsanzo Chodziwika

Glyphosatemosakayikira ndi mankhwala odziwika bwino a herbicide. Amagwiritsidwa ntchito kwambiri chifukwa cha mphamvu yake polamulira udzu wambiri komanso kutsika kwake kawopsedwe kwa mitundu yomwe siidali yoyenera ikagwiritsidwa ntchito moyenera.

Mfundo Zaukadaulo

Chemical Composition

Mankhwala a herbicides amatha kusiyanasiyana m'mapangidwe awo, koma nthawi zambiri amaphatikiza zinthu zomwe zimatha kuyamwa ndikusamutsidwa mkati mwazomera. Zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo glyphosate, 2,4-D, ndi imazapyr.

Njira Zochita

Mankhwala a herbicides amagwira ntchito posokoneza njira zofunikira zamoyo mkati mwa mbewu. Mwachitsanzo, glyphosate imalepheretsa puloteni yomwe imakhudzidwa ndi kaphatikizidwe ka ma amino acid ofunikira, zomwe zimayambitsa kufa kwa mbewu. Mankhwala ophera udzuwa nthawi zambiri amagwiritsidwa ntchito pamasamba kapena dothi ndipo amayamwa ndi mitsempha ya mmera.

Mitundu ya Systemic Herbicides

Mankhwala a herbicides amatha kugawidwa m'magulu angapo kutengera momwe amapangira komanso momwe amachitira:

• Amino Acid Inhibitors (mwachitsanzo, glyphosate)

• Zowongolera Kukula (mwachitsanzo, 2,4-D)
• Lipid Synthesis Inhibitors (mwachitsanzo,quizalofop)

• Photosynthesis inhibitors (mwachitsanzo,atrazine)

Mapulogalamu

Ntchito Zaulimi

Paulimi, mankhwala a herbicides amagwiritsidwa ntchito polimbana ndi udzu wosiyanasiyana womwe umapikisana ndi mbewu kuti ukhale ndi zakudya, kuwala, ndi malo. Amagwiritsidwa ntchito pazigawo zonse zomwe zamera (udzu usanamere) ndi pambuyo pake (udzu utatha kumera).

Kukongoletsa Malo ndi Kulima Dimba

Olima minda ndi olima dimba amagwiritsa ntchito mankhwala ophera udzu kuti asunge malo owoneka bwino powongolera zowononga zamoyo komanso kupewa kumera kwa udzu. Mankhwala ophera udzuwa ndi othandiza makamaka posamalira kapinga, malo a maluwa, ndi minda yokongola.

Forestry Management

M'nkhalango, mankhwala a herbicides amathandizira kusamalira mitundu ya zomera zomwe zingawononge chilengedwe komanso kulepheretsa kukula kwa mitengo. Amagwiritsidwanso ntchito pokonzanso malo okhala kuti athetse zomera zosafunikira.

Ubwino

Kuthetsa Udzu Mogwira Mtima

Mankhwala a herbicides amapereka udzu wochuluka poyang'ana chomera chonse, kuphatikizapo mizu. Izi zimaonetsetsa kuti namsongole achotsedweratu, kuchepetsa mwayi wophukanso.

Kukhudza kwa Nthawi Yaitali pa Mitundu Yosakayika

Poyang'ana bwino ndi kuthetsa mitundu yowononga, mankhwala ophera udzu amathandizira kuteteza madera awo komanso kusunga zamoyo zosiyanasiyana.

Kuchepetsa Kufunika Kogwiritsa Ntchito pafupipafupi

Chifukwa cha momwe amachitira bwino, mankhwala ophera udzu nthawi zambiri amafunikira kugwiritsa ntchito pang'ono poyerekeza ndi mankhwala opha udzu, kuwapangitsa kukhala njira yotsika mtengo yothana ndi udzu.

Kuyerekeza Kuyerekeza

Systemic vs. Contact Herbicides

Mankhwala a herbicides amasiyana ndi okhudzana ndi herbicideschifukwa amasuntha mkati mwa dongosolo la mitsempha ya mmera, kupereka ulamuliro wokwanira. Komano, kukhudzana ndi mankhwala ophera udzu kumakhudza mbali zonse za mmera zomwe zakhudza, zomwe zimapangitsa kuti zisagwire ntchito bwino polimbana ndi namsongole wozika mizu.

Kuyerekeza ndi Njira Zina Zothetsera Udzu

Mankhwala opha tizilombo nthawi zambiri amafaniziridwa ndi njira zowononga udzu (monga kulima, kudula) ndi kuwongolera kwachilengedwe (mwachitsanzo, kugwiritsa ntchito zilombo zachilengedwe). Njira iliyonse ili ndi ubwino wake ndi zofooka zake, ndipo njira zophatikizira zoyendetsera udzu nthawi zambiri zimagwirizanitsa njira zingapo kuti zikhale ndi zotsatira zabwino.

Maupangiri Ogwiritsa Ntchito kapena Maphunziro

Momwe Mungasankhire Mankhwala Oyenera

Kusankha mankhwala ophera udzu woyenerera kumaphatikizapo kuganizira zinthu monga mtundu wa namsongole umene ulipo, mlingo wofunidwa wa kulamulira, ndi mmene chilengedwe chikuyendera. Ngati simukudziwa momwe mungasankhire, chonde tiwuzeni udzu womwe muyenera kuchotsa, ndipo tidzakupatsani malingaliro ndikutumiza zitsanzo kuti muyese!

Njira Zogwiritsira Ntchito

Njira zoyenera zogwiritsira ntchito herbicides ndizofunikira kwambiri kuti muwonjezere mphamvu ya systemic herbicides. Izi zikuphatikizapo kulinganiza zida, kugwiritsa ntchito udzu ukakula bwino, ndi kutsatira malangizo achitetezo kuti muchepetse kuwonongeka kwa chilengedwe.

Chitetezo

Njira zodzitetezera mukamagwiritsa ntchito mankhwala opha udzu ndi monga kuvala zida zodzitchinjiriza, kupewa kuthirira pafupi ndi magwero a madzi, komanso kutsatira malangizo onse olembedwa kuti mupewe kukhudzidwa mwangozi ndi kuwononga chilengedwe.

Mankhwala a herbicides amatha kuwononga zomera zosafunikira. Ngakhale zovuta monga kukhudzidwa kwa chilengedwe komanso kukula kwa kukana, kupita patsogolo kwaukadaulo ndi machitidwe okhazikika zimalonjeza tsogolo labwino lomwe azigwiritsa ntchito.
