Ukususa i-oats yasendle kumasimi engqolowa bekusoloko kuyingxaki kumafama.Nangona kunjalo, ngoku kukho iyeza lokutshabalalisa ukhula ekuthiwa yipropargyl elinokunceda ukusombulula le ngxaki.I-Propargyl yi-aryloxyphenoxypropionic acid inhibitory herbicide enokuthi isuse ngokufanelekileyo i-oats yasendle kunye nolunye ukhula kumasimi engqolowa.Eli nqaku liza kwazisa iimpawu kunye nokusetyenziswa kwe-clodinafop-propargyl kwaye libonelele ngeengcebiso ukunceda amafama ukuba asebenzise kakuhle le michiza yokutshabalalisa ukhula.

Intshayelelo kunye nokusetyenziswa kwepropargyl
I-Aspargyl sisitshabalalisi esiphuhliswe yinkampani yaseSwitzerland iSyngenta, ekwaziwa ngokuba yiclodinal acid okanye ngaphezulu.Isetyenziselwa ikakhulu ukuhluma emva kokuhluma kumasimi engqolowa kwaye inokulawula ngokufanelekileyo ukhula lwengca olufana neoats yasendle kumasimi engqolowa.I-Propargyl ifumaneka kwiintlobo ngeentlobo zemixube, njenge-15% ye-clodinafop microemulsion, i-15% ye-clodinfop yomgubo omanzi, njl njl. Emva kolingo kunye nemiboniso, i-propargyl inempembelelo ebalaseleyo yokulawula kwi-oats yasendle kumasimi engqolowa, ngakumbi i-oats yasendle.Iimpawu zeziphumo zeziyobisi ziya kubonakala kwiintsuku ezimbini emva kokuthatha iyeza.

Xa usebenzisa i-propargyl, kufuneka kuqatshelwe ukuba indawo yokungena ye-pesticide ngokuyinhloko ngamagqabi okanye amaqabunga amaqabunga ezityalo zokhula.Isiphumo sokunyangwa kwesiqu kunye namagqabi singcono, ngelixa isiphumo sokufakwa kwe-pesticide kwiingcambu sincinci.Ukongeza, i-propargyl ayifanelekanga ukulawula ukhula lwe-brome, kwaye kuyacetyiswa ukuba kusetyenziswe ezinye ii-herbicides zokulawula i-brome.Kwingqolowa, ipropargyl lukhetho olukhuselekileyo, kodwa musa ukwandisa okanye ukwandisa umthamo we-arhente ngaphandle kokugunyaziswa ukuphepha i-phytotoxicity ngqolowa.

Uyisebenzisa njani i-clofenac
1. Ukusetyenziswa kwedosi enye
Kwiimeko apho kukho ukhula oluncinci okanye lungekho kwintsimi yengqolowa, i-clofenacet ingasetyenziswa yodwa.Sebenzisa i-15% ye-propargyl yomgubo omanzi, xuba i-14 ~ 20g ye-ejenti namanzi nge-emele nganye, kwaye uphathe izithole zengqolowa.

2. Sebenzisa ngokudibeneyo
Kwiimeko apho ukhula lwengca, ukhula olunamagqabi abanzi kunye neesedge zihlala kwindawo yengqolowa, kucetyiswa ukuba kusetyenziswe i-clodinafop-propargyl zidityaniswe nezinye izibulala-zinambuzane ukuphucula isiphumo sokulukhula.Xa utshiza imichiza yokutshabalalisa ukhula kumasimi engqolowa, ungaxuba i-20 ml ye-20% ye-fluopyron emulsion okanye i-20-40g ye-20% ye-sodium dimethyl tetrachloride umgubo omanzi kunye ne-14-20g ye-15% ye-clofenacetate powder emanzi.Ngokuqinisekileyo, xa isetyenziswe ngokudibeneyo, kuyimfuneko ukuqinisekisa ukuba i-herbicide ekhethiweyo ikhuselekile kwingqolowa.

Ukongeza, ngenxa yoncedo kunye nokhuseleko, i-clodinafop-propagil inokuvela ngendlela yamalungiselelo adibeneyo kunye namanye amayeza.Umzekelo, i-5% ye-pinaclofenac-ethyl emulsifiable concentrate ye-Syngenta yi-concentrate ehlanganisiweyo kunye ne-clodinafop-propargyl njengondoqo kwaye ifanelekile ukulawula ukhula lwegrama ebusika okanye ingqolowa yasentwasahlobo.

Izilumkiso kunye neengcebiso zokusetyenziswa
1. Indawo yokungena ye-clodinafop-ethyl ikakhulu kumagqabi okanye kwizingxobo zamagqabi zokhula, ngoko ke isiphumo sokufakwa kweengcambu sibi.Xa ugalela izitshabalalisi, qinisekisa ukuba isibulali-zinambuzane sidibana ngokupheleleyo namagqabi okhula.

2. Impembelelo yolawulo lwe-propargyl kwi-brome imbi.Kuyacetyiswa ukuba kusetyenziswe ezinye izitshabalalisi ezifanelekileyo ukulawula ibrome ukufumana iziphumo ezingcono.

3. Xa usebenzisa i-15% ye-clofenacet powder emanzi, i-3.75% i-clofenacet inokongezwa ukuxuba ukuphucula ukhuseleko lwengqolowa.

Shwankathela
IPropargyl sisichiza sokutshabalalisa ukhula esisetyenziswa kakhulu kwaye sinefuthe elihle lokulawula ukhula lwengca olufana nehabile yasendle kumasimi engqolowa.Xa usebenzisa i-propargyl, kuyimfuneko ukubeka ingqalelo kwindawo yokungena ye-arhente, ukuvinjelwa kwe-brome ukuxelisa, kunye nokulawulwa kwe-dosage ye-arhente.Kwangaxeshanye, ukusetyenziswa okudityanisiweyo kwe-clodinafop-propargyl kunye nezinye izibulala-zinambuzane kunokuphucula ngakumbi impembelelo yokutshabalalisa ukhula.Ngokusebenzisa iindlela ezifanelekileyo zokusetyenziswa kunye nezilumkiso, abalimi banokusebenzisa ngcono i-clodinafop-propargyl ukusombulula ingxaki ye-oats yasendle kumasimi engqolowa kunye nokuphucula isivuno kunye nomgangatho wezityalo.
