Njira Yogwira Ntchito ndi Kukula kwa Glyphosate

Glyphosate ndi mtundu wa matenda oopsa a phosphic omwe ali ndi EBGraderm Spectram akutuluka. Glyphosate makamaka imabweretsa mavuto chifukwa choletsa biosynthesis amino acid, ndi a bikitokan, tryptophan ndi tyrosiric acid njira. Ili Ndi biosynthesis iyi ya enzymatic imachitika, chifukwa Shikimic acid Sotud Hivo. Kuphatikiza apo, glyphosate amathanso kuletsa mitundu ina ya ma enzymes a syzyme ndi ntchito yanyama. Kagayidwe ka glyphoate mu okwera amakhala pang'onopang'ono ndipo amayesedwa kuti metabolite yake ndi Aminomethylphonic acid ndi methyl amino acetic acetic. Chifukwa cha ntchito yayitali, kuchepa pang'ono, komanso chomera chomera cha glyphosate mu emernnial ement hedbicides a herbicides.glyphosate yagwiritsidwa ntchito kwambiri chifukwa chosankhidwa mwamphamvu Ndipo kupatsa mphamvu bwino, makamaka ndi gawo lalikulu la kulima kwa mbewu za ma glyphosate - zolemetsa za ku Transposent, zakhala herbicida yomwe imagwiritsidwa ntchito kwambiri padziko lapansi.

Malinga ndi kuwunika kwa PMRA, glyphosate alibe genokoxicity ndipo sangakhale pachiwopsezo cha khansa mwa anthu. Palibe chiopsezo thanzi laumunthu lomwe likuyembekezeredwa kudzera pakuwunika kwa zakudya (chakudya ndi madzi) zimagwirizanitsidwa ndi kugwiritsa ntchito glyphosate; Tsatirani malangizo a zilembo, ndipo palibe chifukwa chodera nkhawa za mtundu wa ntchito pogwiritsa ntchito Glyphosate kapena chiopsezo kwa okhalamo. Palibe chiopsezo cha malo omwe akuyembekezeka kugwiritsidwa ntchito ndi zilembo zomwe zakonzedwa, koma malo opukusira amafunikira kuti muchepetse kuwononga nyama zomwe sizingagulitsidwe (zomera, nsomba zam'madzi zolembedwa).

Akuti kugwiritsa ntchito glyphosate ikhale 600,000 ~ 750,000 t mu 2020, ndipo akuyembekezeka kukhala 2040,000 ~ 520,000 ~ 520,000 ~ 520,000 ~ 520,000 ~ 520,000 ~ 520,000 ~ 520,000
