I-Metribuzin

Incazelo emfushane:

I-Metribuzin iyi-herbicide ekhethiwe ye-systemic.Isebenza kakhulu ngokubulala ukhula ngokuvimbela i-photosynthesis yezitshalo ezizwelayo.Ngemuva kokufaka isicelo, ukuhluma kokhula olubucayi akuthinteki.Ingakwazi ukulawula ngempumelelo ukhula lwamaqabunga abanzi onyaka emasimini ehlobo likabhontshisi wesoya.

Izidingo zobuchwepheshe zokusetshenziswa:

1. Isetshenziselwa ukufafaza inhlabathi ngokulinganayo ngemva kokuhlwanyela nangaphambi kwezithombo zikabhontshisi wesoya ehlobo ukuze kugwenywe ukufafaza kakhulu noma ukushoda kokufafaza.

2. Zama ukukhetha isimo sezulu esingenamoya ukuze ufake isicelo.Ngosuku olunomoya noma kulindeleke ukuthi line phakathi nehora elingu-1, ungawusebenzisi umuthi, futhi kuhle ukuwusebenzisa kusihlwa.

3. Isikhathi esisele somphumela we-Metribuzin enhlabathini side kakhulu.Naka ukuhlelwa okufanele kwezitshalo ezilandelayo ukuze uqinisekise isikhawu esiphephile.

4. Sebenzisa isikhathi esingafika ku-1 ngomjikelezo wezitshalo.

Izinyathelo zokuzivikela:

1. Ungasebenzisi umthamo oweqile ukuze ugweme i-phytotoxicity.Uma izinga lokufaka isicelo liphezulu kakhulu noma isicelo singalingani, kuzoba nemvula enkulu noma ukuchelela ngezikhukhula ngemva kokufaka, okuzokwenza ukuthi izimpande zikabhontshisi wesoya zimunce ikhemikhali futhi kubangele ubuthi be-phytotoxic.

2. Ukuphepha kokungazweli emuthini esigabeni sezithombo zikabhontshisi kubi, ngakho-ke kufanele kusetshenziselwe ukwelashwa kwangaphambi kokuhluma.Ukujula kokuhlwanyela kukabhontshisi wesoya okungenani ku-3.5-4 cm, futhi uma ukuhlwanyela kungashoni kakhulu, kungenzeka ukuthi kube ne-phytotoxicity.
