Metribuzin

Inkcazelo emfutshane:

I-Metribuzin sisichiza esikhethiweyo sokutshabalalisa ukhula.Isebenzisa ikakhulu umsebenzi wokutshabalalisa ukhula ngokunqanda ifotosynthesis yezityalo ezibuthathaka.Emva kwesicelo, ukuntshula kokhula olubuthathaka akuchaphazeleki.Inokulawula ngempumelelo ukhula lwamagqabi abanzi onyaka kumasimi eembotyi zesoya ehlotyeni.

Iimfuno zobugcisa zokusetyenziswa:

1. Isetyenziselwa ukutshiza ngokulinganayo umhlaba emva kokuhlwayela naphambi kokufumana izithole zeembotyi zesoya zasehlotyeni ukunqanda ukutshiza kakhulu okanye ukuphosa ukutshiza.

2. Zama ukukhetha imozulu engenamoya ukuze ufake isicelo.Ngosuku olunomoya okanye kulindeleke ukuba kune imvula ngaphakathi kweyure eli-1, musa ukusebenzisa iyeza, kwaye kuyacetyiswa ukuba ulisebenzise ngokuhlwa.

3. Ixesha lesiphumo sentsalela yeMetribuzin emhlabeni lide noko.Nika ingqalelo kulungiselelo olufanelekileyo lwezityalo ezilandelayo ukuze uqinisekise ikhefu elikhuselekileyo.

4. Sebenzisa ukuya kutsho kwixesha eli-1 kumjikelo wesityalo ngasinye.

Ukulumkela:

1. Musa ukusebenzisa umthamo ogqithisileyo ukuze ugweme i-phytotoxicity.Ukuba isantya sokufakwa kwesicelo siphezulu kakhulu okanye isicelo asilingani, kuya kubakho imvula enkulu okanye unkcenkceshelo lwezandyondyo emva kokufakwa, okuya kubangela ukuba iingcambu zesoya zifunxe imichiza kwaye ibangele i-phytotoxicity.

2. Ukhuseleko lokunganyangeki ngamachiza kwinqanaba lembewu yeembotyi zesoya alilunganga, ngoko ke kufuneka lisetyenziswe kuphela kunyango lwaphambi kokuhluma.Ubunzulu bokutyalwa kweembotyi zesoya bubuncinci yi-3.5-4 cm, kwaye ukuba ukuhlwayelwa akunzulu kakhulu, kunokwenzeka ukuba kubekho i-phytotoxicity.
