Ukukhipha i-wild oats emasimini kakolweni bekulokhu kuyinkinga kubalimi.Nokho, manje sekunomuthi wokubulala ukhula obizwa ngokuthi i-propargyl ongasiza ekuxazululeni le nkinga.I-Propargyl iyi-aryloxyphenoxypropionic acid inhibitory herbicide engasusa ngempumelelo i-oats yasendle nolunye ukhula emasimini kakolweni.Lesi sihloko sizokwethula izici nokusetshenziswa kwe-clodinafop-propargyl futhi sinikeze iziphakamiso ezithile zokusiza abalimi ukuthi basebenzise lesi sibulala-khula kangcono.

Isingeniso kanye nokusetshenziswa kwe-propargyl
I-Aspargyl isibulala-zinambuzane esakhiwe yinkampani yaseSwitzerland i-Syngenta, eyaziwa nangokuthi i-clodinal acid noma i-top.Isetshenziswa kakhulu ekuhlumeni ngemuva kokuhluma emasimini kakolweni futhi ingalawula ngempumelelo ukhula lotshani olufana ne-oats yasendle emasimini kakolo.I-Propargyl itholakala ngezindlela ezihlukahlukene, njenge-15% clodinafop microemulsion, 15% clodinfop wettable powder, njll. Ngemva kokuhlolwa kwensimu nemibukiso, i-propargyl inomphumela omuhle kakhulu wokulawula kuma-oats asendle emasimini kakolweni, ikakhulukazi i-oats yasendle.Izimpawu zemiphumela yomuthi zizovela ezinsukwini ezimbili ngemuva kokuphuza umuthi.

Uma usebenzisa i-propargyl, kufanele kuqashelwe ukuthi indawo yokungena ye-pesticide ikakhulukazi amaqabunga noma ama-sheaths amaqabunga ezitshalo zokhula.Umphumela wokwelashwa kwesiqu namaqabunga ungcono, kuyilapho umphumela wokufakwa kwesibulala-zinambuzane ngezimpande uncane.Ngaphezu kwalokho, i-propargyl ayifanele ukulawula ukhula lwe-brome, futhi kunconywa ukusebenzisa amanye ama-herbicides ukulawula i-brome.Kokolweni, i-propargyl iyisinqumo esiphephile, kodwa ungakhulisi noma ukhulise umthamo we-ejenti ngaphandle kokugunyazwa ukugwema i-phytotoxicity kakolweni.

Indlela yokusebenzisa i-clofenac
1. Ukusetshenziswa komthamo owodwa
Ezimweni lapho kukhona ukhula oluncane noma lungekho emasimini kakolweni, i-clofenacet ingasetshenziswa yodwa.Sebenzisa impushana emanzi engu-15% ye-propargyl, hlanganisa u-14 ~ 20g we-ejenti namanzi ibhakede ngalinye, bese uphatha izithombo zikakolweni.

2. Sebenzisa ngokuhlanganisa
Ezimweni lapho ukhula lotshani, ukhula lwe-broadleaf kanye ne-sedge kuhlala ndawonye emasimini kakolweni, kunconywa ukusebenzisa i-clodinafop-propargyl kuhlanganiswe neminye imithi yokubulala ukhula ukuze kuthuthukiswe umphumela wokukhula.Uma ufutha imithi yokubulala ukhula emasimini kakolo, ungaxuba u-20 ml we-emulsion engu-20% ye-fluopyron noma u-20-40g we-20% ye-sodium dimethyl tetrachloride powder emanzi no-14-20g we-15% clofenacetate powder omanzi.Yiqiniso, uma isetshenziswa ngokuhlangene, kuyadingeka ukuqinisekisa ukuthi i-herbicide ekhethiwe iphephile ukolweni.

Ngaphezu kwalokho, ukuze kube lula nokuphepha, i-clodinafop-propagil ingavela futhi ngendlela yamalungiselelo ayinhlanganisela neminye imithi.Isibonelo, i-pinaclofenac-ethyl emulsifiable concentrate ye-Syngenta engu-5% iwukulungiswa okuyinhlanganisela ene-clodinafop-propargyl njengomongo futhi ifanele ukulawula ukhula oluyigramine ebusika noma entwasahlobo kakolweni.

Izixwayiso kanye neziphakamiso zokusetshenziswa
1. Indawo yokungena ye-clodinafop-ethyl ikakhulukazi emaqabunga noma emigodleni yamaqabunga yokhula, ngakho-ke umphumela wokufakwa kwezimpande awubi.Uma usebenzisa izibulala-zinambuzane, qiniseka ukuthi isibulala-zinambuzane sithintana ngokugcwele namahlamvu okhula.

2. Umphumela wokulawula we-propargyl ku-brome mubi.Kunconywa ukusebenzisa amanye ama-herbicides afanelekile ukulawula i-brome ukuze uthole imiphumela engcono.

3. Uma usebenzisa i-15% clofenacet powder wettable, i-clofenacet engu-3.75% ingafakwa ukuze ixutshwe ukuze kuthuthukiswe ukuphepha kukakolweni.

Fingqa
I-Propargyl iyisibulala-khula esisetshenziswa kakhulu futhi inomphumela omuhle wokulawula ukhula otshanini njenge-oats yasendle emasimini kakolweni.Uma usebenzisa i-propargyl, kuyadingeka ukunaka indawo yokungena ye-ejenti, ukuvinjelwa kokulingisa i-brome, nokulawula umthamo we-ejenti.Ngesikhathi esifanayo, ukusetshenziswa okuhlangene kwe-clodinafop-propargyl namanye ama-herbicides kungathuthukisa umphumela wokubulala ukhula.Ngezindlela zokusetshenziswa ezifanele kanye nezinyathelo zokuphepha, abalimi bangasebenzisa kangcono i-clodinafop-propargyl ukuxazulula inkinga ye-oats yasendle emasimini kakolo futhi bathuthukise isivuno kanye nekhwalithi yezitshalo.
