Chigadzirwa tsananguro

Iyo chlorinated diphyenyl compound, diflubenzuron, inogadzirisa kukura kwezvipembenene.Diflubenzuron i benzoylphenyl urea inoshandiswa pazvirimwa zvesango nemumunda kudzora zvipembenene nemaparasite.Zvipembenene zvinonyanya kunangwa imoth yegypsy, gonye retende remusango, moths dzinoverengeka dzinodya zvipfukuto, uye chipfukuto.Inoshandiswawo sekemikari yekudzora makonye mukushanda kwehowa uye mudzimba dzemhuka.Inonyanya kushanda pakurwisana kwezvipembenene, asiwo inoshanda seovicide, inouraya mazai ezvipembenene.Diflubenzuron idumbu uye chepfu yekubata.Inoshanda nekudzivisa kugadzirwa kwechitin, komboni inoita kuti chifukidziro chekunze chechipembenene chive chakaoma uye nokudaro chinokanganisa kuumbwa kwecuticle yezvipembenene kana shell.Inoshandiswa kune ivhu rine utachiona uye inouraya fungus gnat larvae kwemazuva 30-60 kubva pakuiswa kumwe chete.Kunyange zvazvo yakanangana nemakonye efungus, kutarisirwa kunofanirwa kutorwa mukuashandisa sezvo ine muchetura kumhuka zhinji dzemumvura dzisingaite.Iyo haina chepfu mhedzisiro pazvipembenene zvakura, zvipembenene chete zvipembenene zvinobatwa.Diflubenzuron inogona kukonzera kukuvadzwa kwefoliar kune zvinomera mumhuri ye spurge uye mamwe marudzi e begonia, kunyanya poinsettias, hibiscus uye reiger begonia uye haifaniri kushandiswa kune marudzi aya emiti.

Diflubenzuron ine kusamira zvakanaka muvhu.Mwero wekuparara kwevhu unoenderana zvakanyanya nekukura kwechidimbu che diflubenzuron.Inokurumidza kuderedzwa ne microbial process.Hafu yehupenyu muvhu ndeyemazuva matatu kusvika mana.Pasi pemamiriro emumunda, diflubenzuron ine yakaderera kufamba.Diflubenzuron shoma shoma inotorwa, inogadziriswa, kana kuendeswa mumiti.Zvisaririra pazvirimwa zvakaita semaapuro zvine hafu yeupenyu hwemavhiki mashanu kusvika gumi.Iyo hafu yehupenyu muoki mashizha litter ndeye 6 kusvika 9 mwedzi.Mamiriro eDiflubenzuron mumvura anoenderana nepH yemvura.Inoderedza zvakanyanya kukurumidza mumvura yealkaline (hafu yehupenyu izuva 1) uye zvishoma nezvishoma mumvura ine acidic (hafu yeupenyu ndeye 16+ mazuva).Hhafu yehupenyu muvhu iri pakati pemazuva mana nemwedzi mina, zvichienderana nekukura kwechikamu.
