I-Diflubenzuron i-insecticide ekhethiwe yokulawula izinambuzane

Incazelo yomkhiqizo

I-chlorinated diphyenyl compound, i-diflubenzuron, iyisilawuli sokukhula kwezinambuzane.I-Diflubenzuron i-benzoylphenyl urea esetshenziswa ezitshalweni zasehlathini nasezinsimini ukulawula izinambuzane nezilokazane.Izinhlobo zezinambuzane eziqondiswe kuzo i-gypsy moth, isibungu samatende asehlathini, amabhu amaningana ahlala eluhlaza, kanye ne-boll weevil.Ibuye isetshenziswe njengekhemikhali yokulawula izibungu ekusebenzeni kwamakhowe nasezindlini zezilwane.Isebenza kakhulu ngokumelene nezibungu zezinambuzane, kodwa futhi isebenza njenge-ovicide, ebulala amaqanda ezinambuzane.I-Diflubenzuron yisisu kanye nobuthi bokuxhumana.Isebenza ngokuvimbela ukukhiqizwa kwe-chitin, inhlanganisela eyenza isembozo sangaphandle sesinambuzane sibe nzima futhi ngaleyo ndlela iphazamise ukwakheka kwe-cuticle noma igobolondo lesinambuzane.Ifakwa enhlabathini ethelelekile futhi izobulala izibungu ze-fungus gnat izinsuku ezingu-30-60 kusukela ekufakweni okukodwa.Nakuba iqondiswe ezibungwini zomiyane, kufanele kuqashelwe uma isetshenziswa njengoba iyingozi kakhulu ezilwaneni eziningi ezingenamgogodla zasemanzini.Ayinayo imiphumela enobuthi ezinambuzaneni ezindala, izibungu zezinambuzane kuphela ezithintekayo.I-Diflubenzuron ingabangela ukulimala okukhulu kwamaqabunga ezitshalweni zomndeni we-spurge kanye nezinhlobo ezithile ze-begonia, ikakhulukazi i-poinsettias, i-hibiscus ne-reiger begonia futhi akufanele isetshenziswe kulezi zinhlobo zezitshalo.

I-Diflubenzuron inokuphikelela okuphansi emhlabathini.Izinga lokuwohloka enhlabathini lincike kakhulu kusayizi wezinhlayiyana ze-diflubenzuron.Yehliswa ngokushesha ngezinqubo zama-microbial.Ingxenye yempilo enhlabathini yizinsuku ezi-3 kuya kwezi-4.Ngaphansi kwezimo zensimu, i-diflubenzuron inokuhamba okuphansi kakhulu.I-diflubenzuron encane kakhulu iyamuncwa, igaywe imetabolism, noma idluliselwe ezitshalweni.Izinsalela ezitshalweni ezifana nama-apula zinengxenye yempilo yamaviki ama-5 kuya kwayi-10.Ingxenye yempilo kudoti wamaqabunga e-oki yizinyanga eziyisi-6 kuye kweziyi-9.Isiphetho se-Diflubenzuron emanzini sincike ku-pH yamanzi.Yehla ngokushesha kakhulu emanzini ane-alkaline (uhhafu wempilo usuku olu-1) futhi kancane kancane emanzini ane-acidic (uhhafu wempilo yizinsuku eziyi-16+).Ingxenye yempilo enhlabathini iphakathi kwezinsuku ezine nezinyanga ezine, kuye ngosayizi wezinhlayiyana.
