Pali kusiyana kwa mawu amodzi okha pakati pa glyphosate ndi glufosinate-ammonium.Komabe, ambiri ogulitsa zipangizo zaulimi ndi anzako a alimi sakudziwa bwino za "abale" awiriwa ndipo sangathe kuwasiyanitsa bwino.Ndiye pali kusiyana kotani?Glyphosate ndi glufosinate ndizosiyana kwambiri!Ndani amapha udzu bwino?

1. Njira yochitira:Glyphosate imalepheretsa kaphatikizidwe ka mapuloteni ndipo imafalikira kunsi kwa nthaka kudzera mu tsinde ndi masamba.Lili ndi mphamvu zowononga zowononga minyewa yapansi panthaka ya namsongole wozama kwambiri ndipo imatha kufika kuya komwe makina wamba aulimi sangathe kufika.Glufosinate ndi kupha kwa ammonium komwe kumalepheretsa kaphatikizidwe ka glutamine, kumayambitsa kusokonezeka kwa kagayidwe ka nitrogen muzomera.Kuchuluka kwa ammonium kumadziunjikira muzomera ndipo ma chloroplasts amasweka, motero amalepheretsa photosynthesis ya zomera ndipo pamapeto pake amatsogolera ku imfa ya udzu.

2. Kachitidwe: Glyphosate ndi systemic komanso conductive, pomwe glufosinate ndi semi-systemic kapena ofooka kwambiri komanso osayendetsa.

3. Nthawi yopha udzu:Popeza mfundo ya glyphosate ndi kupha mizu ndi mayamwidwe a systemic, nthawi zambiri imagwira ntchito pafupifupi masiku 7-10, pomwe glyphosate imayamba kugwira ntchito masiku 3-5 mutagwiritsa ntchito.

4. Kupalira:Glyphosate imakhudzanso mitundu yopitilira 160 ya namsongole, kuphatikiza monocotyledonous ndi dicotyledonous, pachaka komanso osatha, zitsamba ndi zitsamba.Komabe, kuwononga udzu wina wosatha waudzu sikwabwino.Zotsatira za glyphosate sizodziwikiratu pa namsongole wosamva wowopsa monga goosegrass, knotweed, ndi flyweed;glufosinate ndi mankhwala ophatikizika, opha anthu, opha tizilombo, osatsalira omwe amagwiritsidwa ntchito mosiyanasiyana.Glufosinate itha kugwiritsidwa ntchito pafupifupi mbewu zonse (sizingathe kupopera mbewuzo pagawo lobiriwira).Itha kugwiritsidwa ntchito poletsa udzu pakati pa mizere ya mitengo yazipatso ndi ndiwo zamasamba zobzalidwa m’mizere yotakata komanso m’malo osalimidwa;makamaka kwa udzu wolekerera glyphosate.Udzu wina woopsa, monga cowweed, purslane, ndi namsongole, ndi wothandiza kwambiri.

5. Chitetezo:Glyphosate ndi mankhwala ophera tizilombo omwe amawononga mizu ya mbewu ndipo sangagwiritsidwe ntchito m'minda ya zipatso yosazama mizu.Imakhalabe m'nthaka ndipo imasungunuka kwa nthawi yayitali.Glufosinate alibe pafupifupi mayamwidwe ndi conduction zotsatira mu mizu.Itha kusinthidwa m'nthaka m'masiku 3-4.Nthaka theka moyo ndi zosakwana 10 masiku.Zimakhala ndi mphamvu zochepa pa nthaka, mizu ya mbewu ndi mbewu zotsatila.
