Ngati ndinu mlimi wokonda dimba kapena mlimi, mukudziwa kufunika koteteza mbewu zanu ku tizirombo.Njira imodzi yothandiza kwambiri yochitira zimenezi ndi kugwiritsa ntchito mankhwala ophera tizilombo amene angawononge mbewu.Komabe, si mankhwala onse ophera tizilombo omwe amapangidwa mofanana, ndipo ndikofunikira kusankha yoyenera pavuto lanu la tizilombo.Mankhwala ophera tizilombo omwe tiyenera kuwaganizira ndi pymetrozine, mankhwala omwe awonetsedwa kuti ndi othandiza kwambiri polimbana ndi tizirombo tomwe timadya madzi.

Pymetrozine ndi systemic insecticide, kutanthauza kuti imagwiritsidwa ntchito ku zomera ndikuyamwa ndi minyewa yawo.Ikalowa mkati, imalepheretsa kuti tizilombo ting'onoting'ono ting'onoting'ono ting'onoting'ono ting'onoting'ono ting'onoting'ono ting'onoting'ono tife.Zimagwira ntchito poletsa dongosolo lamanjenje la tizilombo, zomwe zimapangitsa kuti asiye kudya ndi kufooka.Izi zimapangitsa kukhala chisankho chabwino kwambiri chothana ndi tizirombo monga nsabwe za m'masamba, mealybugs ndi leafhoppers.

Kugwiritsa ntchito pymetrozine ndikosavuta.Amagwiritsidwa ntchito kwambiri ngati kupopera masamba ndipo amatha kupakidwa molunjika ku mbewu pogwiritsa ntchito sprayer.Kupopera mbewu mankhwalawa kuyenera kulunjika kunsi kwa masamba, pomwe tizirombo tambiri toyamwa timadzi timakonda kusonkhana.Pymetrozine nthawi zambiri imakhala yothandiza kwa milungu iwiri mutagwiritsa ntchito, koma ndi bwino kutsatira malangizo omwe ali pa lebulo.

Chimodzi mwazabwino kwambiri za Pymetrozine ndikusankha kwake.Mosiyana ndi mankhwala ena ambiri ophera tizilombo, pymetrozine ilibe vuto kwa tizilombo topindulitsa monga ladybugs ndi lacewings, ndipo imathandizira kulamulira tizirombo tina.Izi zimapangitsa kukhala chisankho chabwino kwambiri kwa alimi ndi wamaluwa omwe akufuna kuteteza mbewu zawo popanda kuwononga chilengedwe.

Pomaliza, ngati mukuyang'ana mankhwala ophera tizilombo omwe amathandizira kwambiri komanso osawononga chilengedwe kuti muteteze mbewu zanu ku tizirombo toyamwa madzi, pymetrozine ndiyofunikira kuiganizira.Zomwe zimapangidwira zimatsimikizira kuti zimatengedwa ndi zomera ndipo zimakhalabe zogwira mtima kwa masabata awiri mutatha kugwiritsa ntchito, pamene kusankha kwake kumatsimikizira kuti sikuvulaza tizilombo topindulitsa.Ndiye bwanji osayesa pymetrozine nyengo yotsatira yakukula ndikuwona momwe ingathandizire mbewu zanu kuti zikule bwino!
