Msika waukulu wa Lufenoron uli m'munda wa matenda a nyama, omwe amagwiritsidwa ntchito kulamulira amphaka ndi agalu, ndipo amagwiritsidwa ntchito makamaka ku zipatso, thonje, chimanga, mitengo yazipatso ku China. Imatha kuwongolera tizirombo ndipo zimagwira ntchito kwambiri polimbana ndi masamba osiyanasiyana a levidoptera. Itha kugwiritsidwanso ntchito kuwongolera zoboola ndi tizirombo tokha, makamaka chifukwa cha beedwirlurm, a SpodOptera, gulu lankhondo, gulu lankhondo ndi tizirombo tina ena osagwira bwino ntchito. Makina ake osokoneza bongo amagwira ntchito poletsa mapangidwe a Chitin Syntase mu mphutsi, kusokoneza mawonekedwe a chitin pa epiden pa epidermis, ndikupangitsa tizilombo toyambitsa matenda.
Chachikulu
Lufenuron · ternkyril (makamaka kuti azilamulira njuchi);
Lufenuromonh · chlyoryritos (makamaka kuwongolera thonje mabotolo);
Emmeroctinan · Luamenuron (makamaka kuwongolera spaceptera ExitIgua);
Abamectinaron (makamaka kuti aziwongolera matumbo a dzimbiri), etc.
Nthawi Yosatha (Lufnoron> Chlorfenapy)
Lufenron ali ndi vuto lakupha dzira la dzira lambiri, ndipo nthawi yolamulira ya tizilombo itakhala yotalikirapo, mpaka masiku 25; Chlorfenapr isaphe mazira, ndipo imangoyendetsa bwino kwambiri tizilombo tating'onoting'ono. Nthawi yolamulira ndi masiku pafupifupi 7-10.
Kusunga kwa tsamba (Lufnoron> ChlorFenapr)
Poyerekeza ndi zowongolera masamba a mpunga, tsamba la masamba a Lufnuron amatha kufikira 90%, ndipo tsamba losunga tsamba la Chlorfenapyr a pafupifupi 65%.
Chitetezo (Lufnoron> ChlorFenapy)
Lufenron alibe yankho ku phytotoxicity mpaka pano. Nthawi yomweyo, wothandizirayo sadzayambitsa tizirombo tokhometsa kuti chikhale ponseponse. Zimakhala zofatsa tizilombo topatsa tizilombo toyambitsa matenda komanso zolusa. Chuma chambiri. Kapena kugwiritsa ntchito mlingo wambiri kumakonda phytotoxicity.
Tizilombo toyambitsa matenda (chlorfenapyr> lufeneron)
Lufennuron amagwiritsidwa ntchito makamaka kuwongolera masamba, plutela xylostella, pludella xylostella, spaceptera exodra, ndi ziweto, zidutswa zam'madzi ndi tizirombo tina. Amakhala otchuka kwambiri pakuwongolera tsamba la mpunga. Chlorfenapy ali ndi zotsatira zabwino kwambiri pakubowola, kuyamwa nthabwala ndi kutafuna machenjere, masamba a spaceptera, ndipo nthungo pakati pa tizirombo toyambitsa matenda. Akavalo, nthanga za kangaude, etc. ali ndi zotsatira zofunika.
Kusamalitsa
1. Ali ndi kukana kwa Hexafluuron, chlorfluaziron, Diflubenzuron, etc.; Siyenera kusakanikirana ndi carbamani monga methomyl ndi Thudicarb;
2. Lufennuron amatenga masiku 3-5 kuti afikire nthawi ya peak tizilombo, motero ndikofunikira kuponda mankhwala ena okhazikika. Monga EmAmectin Benzoate ndi zina zotero.
3. Simungasakanizidwe ndi othandizira alkaline;
4. Ndi zoopsa kwambiri kwa crustaceans, ndipo ndizosaloledwa kuderera mitsinje, nyanja, maiwe ena ndi madzi ena ndi mankhwala otsala ndi zinyalala zamadzimadzi zamadzimadzi.
