Kuchotsa oats kutchire m'minda ya tirigu wakhala vuto kwa alimi.Komabe, tsopano pali mankhwala ophera udzu otchedwa propargyl omwe angathandize kuthetsa vutoli.Propargyl ndi aryloxyphenoxypropionic acid inhibitory herbicide yomwe imatha kuchotsa bwino oats zakutchire ndi udzu wina m'minda ya tirigu.Nkhaniyi ifotokoza za kagwiritsidwe ntchito ka clodinafop-propargyl ndikupereka malingaliro othandizira alimi kugwiritsa ntchito bwino mankhwalawa.

Chiyambi ndi kugwiritsa ntchito propargyl
Aspargyl ndi mankhwala ophera udzu opangidwa ndi kampani yaku Swiss Syngenta, yomwe imadziwikanso kuti clodinal acid kapena top.Amagwiritsidwa ntchito kwambiri popalira pambuyo pa kumera m'minda ya tirigu ndipo amatha kuwongolera udzu wa udzu monga oats wamtchire m'minda ya tirigu.Propargyl imapezeka m'mapangidwe osiyanasiyana, monga 15% clodinafop microemulsion, 15% clodinfop ufa wonyowa, ndi zina zotero. Pambuyo pa mayesero a m'munda ndi ziwonetsero, propargyl imakhala ndi mphamvu yolamulira pa oats zakutchire m'minda ya tirigu, makamaka oats zakutchire.Zizindikiro za zotsatira za mankhwala zidzawoneka patatha masiku awiri mutamwa mankhwalawa.

Mukamagwiritsa ntchito propargyl, ziyenera kudziwidwa kuti malo olowera mankhwala ophera tizilombo ndi masamba kapena masamba a udzu.Zotsatira za chithandizo cha tsinde ndi masamba zimakhala bwino, pamene zotsatira za mankhwala ophera tizilombo kudzera mu mizu ndizochepa.Kuphatikiza apo, propargyl siyoyenera kuletsa udzu wa brome, ndipo tikulimbikitsidwa kugwiritsa ntchito mankhwala ena opha herbicides polimbana ndi brome.Kwa tirigu, propargyl ndi chisankho chotetezeka, koma musawonjezere kapena kuonjezera mlingo wa wothandizira popanda chilolezo kuti mupewe phytotoxicity mu tirigu.

Momwe mungagwiritsire ntchito clofenac
1. Kugwiritsa ntchito mlingo umodzi
Ngati pali udzu wochepa kapena mulibe m'munda wa tirigu, clofenacet ingagwiritsidwe ntchito yokha.Gwiritsani ntchito 15% ufa wonyowa wa propargyl, sakanizani 14 ~ 20g ya mankhwalawa ndi madzi pa ndowa, ndikutsuka mbande za tirigu.

2. Gwiritsani ntchito kuphatikiza
Pamalo omwe udzu, udzu, udzu ndi nthanga zimakhalira m'minda ya tirigu, ndi bwino kugwiritsa ntchito clodinafop-propargyl pamodzi ndi mankhwala ena ophera udzu kuti athetse udzu.Mukapopera mankhwala ophera tizilombo m'minda ya tirigu, mutha kusakaniza 20 ml ya 20% fluopyron emulsion kapena 20-40g ya 20% sodium dimethyl tetrachloride ufa wonyowa ndi 14-20g wa 15% clofenacetate ufa wonyowa.Zoonadi, akagwiritsidwa ntchito pamodzi, m'pofunika kuonetsetsa kuti herbicide yosankhidwa ndi yabwino kwa tirigu.

Kuphatikiza apo, chifukwa chosavuta komanso chitetezo, clodinafop-propagil imatha kuwonekanso ngati mankhwala ophatikizika ndi mankhwala ena.Mwachitsanzo, 5% pinaclofenac-ethyl emulsifiable concentrate ya Syngenta ndi mankhwala ophatikizika okhala ndi clodinafop-propargyl monga pachimake ndipo ndi oyenera kulamulira udzu wa gramineous nthawi yozizira kapena masika.

Kusamala ndi malingaliro ogwiritsira ntchito
1. Malo olowera a clodinafop-ethyl amakhala makamaka m'masamba kapena m'chimake cha udzu, kotero kuti mizu yake imamera bwino.Mukathira mankhwala ophera tizirombo, onetsetsani kuti mankhwalawa akhudza masamba a udzu.

2. Mphamvu zowongolera za propargyl pa brome ndizosauka.Ndibwino kuti mugwiritse ntchito mankhwala ena ophera udzu kuti muteteze brome kuti mupeze zotsatira zabwino.

3. Mukamagwiritsa ntchito 15% clofenacet ufa wonyezimira, 3.75% clofenacet ikhoza kuwonjezeredwa kusakaniza kuti mukhale ndi chitetezo cha tirigu.

Fotokozerani mwachidule
Propargyl ndi mankhwala ophera udzu omwe amagwiritsidwa ntchito kwambiri ndipo amatha kuwongolera udzu monga oats wamtchire m'minda ya tirigu.Mukamagwiritsa ntchito propargyl, ndikofunikira kulabadira malo olowera a wothandizira, kuletsa kutsanzira kwa brome, ndikuwongolera mlingo wa wothandizila.Panthawi imodzimodziyo, kugwiritsa ntchito clodinafop-propargyl ndi mankhwala ena a herbicides kungapangitsenso kusintha kwa herbicidal.Kupyolera mu njira zogwiritsiridwa ntchito bwino ndi kusamala, alimi angagwiritse ntchito bwino clodinafop-propargyl kuthetsa vuto la oats wamtchire m'minda ya tirigu ndi kupititsa patsogolo zokolola ndi ubwino wa mbewu.
