Cov tshuaj tua kab xws li Tebuconazole, Gibberellic Acid thiab Flonicamid yuav txuas ntxiv rau lub sijhawm siv tau

Agrochemical.com Suav lub vev xaib tau tshaj tawm: Tsis ntev los no, raws li PPP cov cai rau kev tiv thaiv cov khoom lag luam (REGULATION (EC) No 1107/2009), European Union tau txuas ntxiv 28 txoj cai rau gibberellic acid, flonicamid, tebuconazole, thiab chlorpyrazosulfuron-methyl. Hnub tas sij hawm ntawm cov tshuaj nquag.

Ntawm cov tshuaj no, gibberellic acid yeej ib txwm yog cov khoom nrov uas tau txais kev saib xyuas thoob plaws.

Qhov tseem ceeb ntawm Gibberellik Acid

Gibberellic acid (Gibberellic acid, GA3) belongs rau gibberellin chav kawm ntawm cov nroj tsuag kev loj hlob regulators, thiab yog ib tug ubiquitous endogenous hormone nyob rau hauv cov nroj tsuag.

Xyoo 1935, gibberellic acid tau ua tiav los ntawm Gibberella thawj zaug, thiab tom qab ntawd Abbott Laboratories hauv Tebchaws Meskas, ICI hauv tebchaws United Kingdom thiab Kyowa Fermentation hauv Nyij Pooj tau ua tiav rau hauv kev tsim khoom.

Gibberellic acid yog ib qho tseem ceeb endogenous hormone uas txhawb cov nroj tsuag kev loj hlob thiab kev loj hlob. Artificially tsim gibberellic acid yog absorbed los ntawm nplooj, paj, noob, twigs los yog txiv hmab txiv ntoo, thiab ces thauj mus rau qhov chaw ntawm kev txiav txim nyob rau hauv cov nroj tsuag lub cev. Gibberellic acid tuaj yeem ua si ntau lub luag haujlwm ntawm lub cev, xws li:

• Ua kom cov txiv hmab txiv ntoo loj hlob sai thiab txhawb nqa cov txiv hmab txiv ntoo;

• Tso cov noob dormancy thiab txhawb kev loj hlob thaum ntxov;

• Accelerates elongation thiab kev loj hlob ntawm stems thiab txhawb bolting ntawm cov nroj tsuag;

• Txhim kho thaj chaw nplooj thiab ua kom lub cambium;

• Inhibit maturation thiab senescence, hinder lateral bud dormancy thiab tuber tsim, thiab lwm yam.

Tsis tas li ntawd, gibberellic acid yog tam sim no siv ntau tshaj plaws nyob rau hauv kuv lub teb chaws, txawm nws yog mov, nplej, pob kws, qos yaj ywm thiab lwm yam qoob loo, los yog txiv hmab txiv ntoo thiab zaub xws li txiv hmab txiv ntoo, txiv lws suav, cucumbers, cherries, los yog paj xws li rhododendron. thiab magnolia, gibberellic acid tuaj yeem ua lub luag haujlwm zoo.

Hnub tas sij hawm kawg ntawm 28 cov tshuaj nquag xws li gibberellic acid

Tam sim no, gibberellic acid tau sau npe hauv Suav teb, Tebchaws Asmeskas, European Union, Brazil thiab lwm lub tebchaws thiab cheeb tsam. Raws li lub Xya Hli 2023, gibberellic acid muaj tag nrho ntawm 22 kev sau npe thiab 221 kev npaj sau npe hauv Suav teb.

Txij li thaum rov ntsuam xyuas kev ua haujlwm tsis tuaj yeem ua tiav ua ntej lub sijhawm siv tau qub, EU tshaj tawm kom txuas ntxiv lub sijhawm siv tau ntawm gibberellic acid mus rau Lub Xya Hli 15, 2025.

Daim ntawv ceeb toom txog kev txuas ntxiv ntawm lub sijhawm siv tau ntawm cov tshuaj nquag hauv EU kuj suav nrog cov tshuaj nquag xws li flonicamid, tebuconazole, thiab chlorpyrazosulfuron-methyl. Cov ntaub ntawv tshwj xeeb yog raws li nram no:
