Diflubenzuron kusankha tizilombo towononga tiziromboti
Mafotokozedwe Akatundu
Mankhwala a chlorinated diphyenyl, diflubenzuron, ndiwowongolera kukula kwa tizilombo.Diflubenzuron ndi benzoylphenyl urea yomwe imagwiritsidwa ntchito pa nkhalango ndi mbewu za m'munda posankha tizilombo toyambitsa matenda.Tizilombo tomwe timakonda kwambiri ndi njenjete, njenjete za m'nkhalango, njenjete zingapo zomwe zimadya nthawi zonse, ndi njenjete.Amagwiritsidwanso ntchito ngati mankhwala oletsa mphutsi popanga bowa ndi nyumba za ziweto.Ndizothandiza makamaka motsutsana ndi mphutsi za tizilombo, komanso zimakhala ngati ovicide, kupha mazira a tizilombo.Diflubenzuron ndi m'mimba ndi kukhudzana poizoni.Zimagwira ntchito poletsa kupanga chitin, chinthu chomwe chimapangitsa chophimba chakunja cha tizilombo kukhala cholimba ndipo motero chimasokoneza mapangidwe a cuticle kapena chipolopolo cha tizilombo.Amathiridwa pa dothi lodwala ndipo amapha mphutsi za bowa kwa masiku 30-60 kuchokera pakugwiritsa ntchito kamodzi.Ngakhale kuti amalimbana ndi mphutsi za udzudzu, tiyenera kusamala pougwiritsa ntchito chifukwa ndi poizoni kwambiri kwa tizilombo tomwe timakhala m'madzi.Zilibe poizoni kwa tizilombo akuluakulu, mphutsi za tizilombo zokha zimakhudzidwa.Diflubenzuron ikhoza kuvulaza kwambiri zomera za m'banja la spurge ndi mitundu ina ya begonia, makamaka poinsettias, hibiscus ndi reiger begonia ndipo sayenera kugwiritsidwa ntchito pa mitundu ya zomera izi.
Diflubenzuron imakhala ndi kulimbikira kochepa m'nthaka.Kuwonongeka kwa nthaka kumadalira kwambiri kukula kwa tinthu ta diflubenzuron.Imawonongeka mofulumira ndi njira za tizilombo toyambitsa matenda.Theka la moyo m'nthaka ndi masiku 3 mpaka 4.Pansi pamikhalidwe yam'munda, diflubenzuron imakhala yotsika kwambiri.Diflubenzuron yaying'ono kwambiri imatengeka, imapangidwa ndi metabolism, kapena imasamutsidwa muzomera.Zotsalira pa mbewu monga maapulo zimakhala ndi theka la moyo wa masabata 5 mpaka 10.Theka la moyo mu zinyalala za masamba a oak ndi miyezi 6 mpaka 9.Tsogolo la Diflubenzuron m'madzi limadalira pH yamadzi.Imawonongeka kwambiri m'madzi amchere (theka la moyo ndi tsiku limodzi) komanso pang'onopang'ono m'madzi acidic (theka la moyo ndi masiku 16+).Theka la moyo m'nthaka ndi pakati pa masiku anayi ndi miyezi inayi, kutengera kukula kwa tinthu.
