Tizilombo toyambitsa matenda tingawononge kwambiri chimanga, ndipo mankhwala ophera tizilombo a chimanga amatha kuwononga tizilombo tosiyanasiyana.Ndiye ngati chimanga chapopera mankhwala ophera tizirombo komanso fungicides, kodi tiyenera kupopera mankhwala a herbicide tsiku lotsatira?

Choyamba, zimatengera kuchuluka kwa mankhwala omwe adagwiritsidwa ntchito dzulo lake komanso zomwe zidagwiritsidwa ntchito tsiku lotsatira.

Ngati anali fungicide dzulo kuti ateteze matenda, ndiye kuti ndibwino.Tsiku lotsatira mukhoza kugwiritsa ntchito herbicide;Ngati mankhwalawa adagwiritsidwa ntchito dzulo, zimatengera momwe zinthu ziliri.

Nthawi ina, mankhwala a herbicide omwe atuluka pambuyo pake sangathe kugwiritsidwa ntchito tsiku lotsatira.

Pali zinthu ziwiri zofunika kuzikwaniritsa.Chimodzi ndi chakuti chigawo chopha tizilombo ndi phosphorous organic.Mtundu (monga chlorpyrifos kapena phoxim), chachiwiri ndikuti chigawo cha herbicide chili ndi nicosulfuron.Zinthu ziwirizi zikakwaniritsidwa, mankhwala a herbicide sangathe kugwiritsidwa ntchito tsiku lotsatira, chifukwa n'zosavuta kupanga kuwonongeka kwa herbicide , Zimakhudza zokolola za chimanga.Njira yolondola ndi kupanga nthawi ya masiku 7 pakati pa awiriwo.Izi ndi zofunika kwambiri.Ndikukhulupirira kuti aliyense adzamvetsera.

Kachiwiri, ngati mankhwala a herbicides atha kupopera tsiku lotsatira zimadalira kusintha kwa nyengo.

Ngati kuli mvula kapena mphepo yamkuntho tsiku lotsatira, sikoyenera kupopera mankhwala ophera udzu.Pansi pa kukumana ndi yapitayi, aliyense amadziwa kuti masiku amvula ndi Ngati simungathe kugwiritsa ntchito mankhwala ophera tizilombo, osatchula zowonongeka, n'zosavuta kupanga phytotoxicity, ndipo simungagwiritse ntchito mankhwala ophera tizilombo mu mphepo yamkuntho.

Lumikizanani nafe kudzera pa imelo ndi foni kuti mumve zambiri komanso mawu
