Zeziphi izinambuzane ezinokubulawa zizinambuzane ze-pyrethroid

 Izibulali-zinambuzane eziqhelekileyo ze-pyrethroid ziqukaI-Cypermethrin, I-Deltamethrin, i-cyfluthrin, kunye ne-cypermethrin, njl.

I-Cypermethrin: Isetyenziselwa kakhulu ukulawula izinambuzane ezityayo nezimunca umlomo kunye neencukuthu ezahlukeneyo zamagqabi.

I-Deltamethrin: Isetyenziswa kakhulu ukulawula izinambuzane zeLepidoptera kunye ne-homoptera, kwaye ikwanefuthe elithile kwizinambuzane ze-Orthoptera, iDiptera, i-hemiptera kunye neColeoptera.

I-Cyanothrin: Isetyenziswa kakhulu ukulawula izinambuzane ze-lepidoptera, kwaye ikwanegalelo elihle kwizinambuzane ze-homoptera, i-hemiptera kunye ne-diptera.

Yintoni ekufuneka iqatshelwe xa kutshizwa izinambuzane

1. Xa usebenzisaizibulali-zinambuzaneUkulawula izinambuzane ezitshabalalisa izityalo, kuyimfuneko ukukhetha izibulali-zinambuzane ezifanelekileyo nokuzisebenzisa ngexesha elifanelekileyo. Ngokusekelwe kwiimpawu zemozulu kunye neendlela zokusebenza kwezinambuzane ngosuku, izibulali-zinambuzane kufuneka zisetyenziswe ngamaxesha afanelekileyo. Kucetyiswa ukuba kusetyenziswe izibulali-zinambuzane phakathi kwentsimbi ye-9 neye-10 kusasa nasemva kwentsimbi yesi-4 emva kwemini.

2. Emva kwentsimbi ye-9 kusasa, umbethe kumagqabi esityalo womile, kwaye lixesha apho izinambuzane eziphuma ekuphumeni kwelanga zisebenza kakhulu. Ukusebenzisa izibulali-zinambuzane ngeli xesha akuyi kuchaphazela impembelelo yolawulo ngenxa yokuxutywa kwesisombululo sezibulali-zinambuzane ngumbethe, kwaye akuyi kuvumela izinambuzane ukuba zinxibelelane ngqo nesibulali-zinambuzane, nto leyo eyandisa amathuba okutyhefwa zizinambuzane.

3. Emva kwentsimbi yesi-4 emva kwemini, ukukhanya kuyaphela kwaye lixesha apho izinambuzane ezibhabhayo nezisebusuku ziza kuphuma. Ukusebenzisa izibulali-zinambuzane ngeli xesha kunokuvumela ukuba izibulali-zinambuzane zisetyenziswe kwizityalo kwangaphambili. Xa izinambuzane ziphuma ukuze zisebenze okanye zitye ebusuku, ziya kudibana netyhefu okanye zityhefwe ngokutya zize zife. Kwangaxeshanye, kunokuthintela ukulahleka komphunga kunye nokungaphumeleli kwesisombululo sezibulali-zinambuzane.

4.Kufuneka kukhethwe iindlela ezahlukeneyo zokubulala izinambuzane kunye neendlela zokusebenzisa ngokusekelwe kwiindawo ezonakeleyo zezinambuzane, kwaye izibulali-zinambuzane mazisiwe kwindawo efanelekileyo. Kwizinambuzane ezonakalisa iingcambu, faka isibulali-zinambuzane kwiingcambu okanye kwimisele yokutyala. Kwizinambuzane ezonakalisa ngaphantsi kwamagqabi, fafaza iyeza elilulwelo phantsi kwamagqabi.

 5. Ukulawula iimbongolo ezibomvu kunye neembongolo zekotoni, faka iyeza kwiintyatyambo, iintsimbi eziluhlaza kunye neencam zeqela. Ukuthintela i-螟虫 kunye nokubangela izithole ezifileyo, fafaza umhlaba onetyhefu; Ukuthintela nokulawula ii-panicles ezimhlophe, fafaza okanye ugalele amanzi. Ukulawula iimbongolo zerayisi kunye neembongolo zerayisi, fafaza iyeza elilulwelo kwisiseko sezityalo zerayisi. Ukulawula i-diamondback moth, fafaza iyeza elilulwelo kwiintyatyambo kunye neepods ezincinci.

 6. Ukongeza, kwizinambuzane ezifihlakeleyo ezifana nee-cotton aphids, izigcawu ezibomvu, i-race planthoppers, kunye ne-race leafhoppers, ngokusekelwe kwindlela yazo yokufunxa nokubhoboza umlomo, izibulali-zinambuzane ezinamandla zinokukhethwa. Emva kokufunxa, zingadluliselwa kwezinye iindawo zesityalo ukufezekisa injongo yokuhambisa isibulali-zinambuzane kwindawo efanelekileyo.
