Iyi kit yakakodzera kutariswa kwemhando yezvakasara isoprocarb mune nyowani cucumber sample.

Isoprocarb inobata-uye-kuuraya, inokurumidza-kuita-mushonga wezvipembenene, iri mushonga une chepfu.Inonyanya kushandiswa kudzora rice planthopper, mupunga cicada nezvimwe zvipembenene pamupunga, mimwe miti yemichero nezvirimwa.Muchetura wenyuchi nehove.

Yakakwira performance liquid chromatography-tandem mass spectrometry yakashandiswa pakusarira kutsunga nekuda kwekusarudzwa kwepamusoro uye kurapwa kuri nyore.Ckuenzaniswa neHPLCnzira,kit yeduratidza mabhenefiti akakura maererano nekunzwa, muganhu wekuona, tekinoroji zvishandiso uye nguva inodiwa.

Mienzaniso yekugadzirira

(1)Usati waedzwa, sampuli dzinofanirwa kudzoserwa kune tembiricha yekamuri (20-30).

Zvitsva zvinofanira kutorwa kupukuta ivhu uye kucheka kuita zvidimbu zvisingasviki 1cm square.

(2) Weresa 1.00± 0.05g sampuli mu15mL polystyrene centrifuge chubhu, wobva wawedzera 8mL inobvisa, vhara chivharo, oscillate kumusoro uye pasi nemaoko kwe30s, uye rega imire kwe1min.Supernatant liquid ndiyo sampuli inofanira kuongororwa.

Ongorora: Nzira yesampling inoreva maitiro ekuongorora kuchengetedzwa kwechikafu (aqsiq decree no. 15 of 2019).GB2763 2019 yekutarisa.

Results

Negative(-): Mutsara T uye Mutsara C zvose zvitsvuku, ruvara rweMutsetse T rwakadzika kudarika kana rwakafanana neMutsetse C, zvichiratidza kuti isoprocarb mumuenzaniso ishoma pane LOD yekiti.

Zvakanaka(+): Mutsara C wakatsvuka, ruvara rwemutsara T hauna simba kudarika mutsara C, zvichiratidza isoprocarbl mumuenzaniso yakakwirira kudarika LOD yekiti.

Hazvina basa: Mutsetse C hauna ruvara, izvo zvinoratidza kuti mitsetse haina kushanda.Muchiitiko ichi, ndapota verenga mirairo zvakare, uye dzokorora bvunzo netambo nyowani.
