Ndi mankhwala ati omwe ali ndi mphamvu, Lufenuron kapena Chlorfenapyr?

Lufenuron

Lufenuron ndi mtundu wachangu kwambiri, yotakata sipekitiramu ndi otsika kawopsedwe tizilombo kuti ziletsa kusungunula tizilombo.Zimakhala ndi poizoni wa m'mimba, komanso zimakhala ndi zotsatira zina.Ilibe chidwi chamkati, koma imakhala ndi zotsatira zabwino.Zotsatira za Lufenuron pa mphutsi zazing'ono ndizabwino kwambiri.Titadya zomera zopopera mankhwala, tizirombo timasiya kudya kwa maola awiri ndikulowa pachimake cha tizilombo takufa m'masiku 2-3.

Ndizotetezeka kwa adani ambiri achilengedwe chifukwa chakuchita kwake pang'onopang'ono komanso nthawi yayitali yochitapo kanthu.

Chlorfenapyr

Chlorfenapyr imakhudzanso ntchito ya ovicidal.Kuphatikizidwa ndi kuneneratu ndi kulosera kwa tizirombo, akuti kutsitsi kumatha kuwongolera bwino pamlingo wa nsonga za kuswa kapena kuswa dzira.

Chlorfenapyr ili ndi madulidwe abwino am'deralo muzomera, ndipo zotsatira zomwezo zitha kupezeka pansi pamasamba odyetsedwa ndi tizirombo.

The ulamuliro zotsatira ndi 90-100% mkati L-3 masiku pambuyo mankhwala, ndi zotsatira akadali khola pa 90% mkati 15 masiku mankhwala.Mlingo wovomerezeka ndi 30-40 ml pa muyeso, ndi nthawi ya masiku 15-20.

Chisamaliro chapadera chiyenera kuperekedwamukugwiritsa ntchito Chlorfenapyr:

1) Zimakhudzidwa ndi mavwende, zukini, mphonda wowawa, vwende, cantaloupe, mphonda woyera, dzungu, cantaloupe, loofah ndi mbewu zina.Osavomerezeka achinyamata tsamba siteji.

2) Pewani kugwiritsa ntchito mankhwala pa kutentha, maluwa siteji ndi mmera siteji;

Kusiyana pakatiChlorfenapyr ndiLufenuron

1. Njira zophera tizilombo

Lufenuron ali ndi zotsatira za poizoni m'mimba ndi kukhudza, palibe kukhumba mkati, kupha dzira lamphamvu;

Chlorfenapyr ili ndi kawopsedwe ka m'mimba komanso tactility, ndipo imakhala ndi mayamwidwe ena mkati.

Kugwiritsa ntchito osmotic/extender agents (mwachitsanzo, silikoni) kumawonjezera mphamvu yakupha.

2. Mankhwala ophera tizilombo

Iwo makamaka ntchito kulamulira tsamba wodzigudubuza, Plutella xylostella, Rapeseed, beet armyworm, Spodoptera litura, whitefly, thrips, dzimbiri nkhupakupa ndi tizirombo ena, makamaka pa ulamuliro wa mpunga tsamba wodzigudubuza.

Lufenuron imathandiza kwambiri tizirombo ndi nthata, makamaka tizirombo tolimbana ndi tizirombo monga Plutella xylostella, Exigua beet armyworm, Exigua chinensis, leaf roller, American spot miner, pod borer, thrips ndi kangaude wa nyenyezi.

Chifukwa chake, kusiyana kwakukulu malinga ndi kuchuluka kwa tizilombo ndi: Chlorfenapyr> Lufenuron> Indoxacarb

3, Kupha liwiro

The tizilombo kukhudzana ndi mankhwala ndi kudya masamba ndi mankhwala, pakamwa adzakhala anesthetized mkati 2 hours, kusiya kudyetsa, kuti asiye kuwononga mbewu, 3-5 masiku kufika pachimake tizilombo akufa;

Ola limodzi pambuyo pa mankhwala ophera tizilombo fenfenitrile, ntchito ya tizirombo inakhala yofooka, mawanga anawonekera, mtundu unasintha, ntchito inasiya, chikomokere, chikomokere, ndipo pamapeto pake chinayambitsa imfa, ndipo chiwopsezo cha tizilombo takufa chinafikira maola 24.

Chifukwa chake, malinga ndi liwiro la tizilombo, kufananitsa ndi: Chlorfenapyr> Lufenuron

4. Nthawi yosungira

Lufenuron ali ndi mphamvu ya ovicidal, ndipo nthawi yowononga tizilombo ndi yaitali, mpaka masiku 25;

Chlorfenapyr sichimapha mazira, koma imagwira ntchito kwa tizilombo tokalamba, ndipo nthawi yolamulira ndi masiku 7-10.

Chlorfenapyr > Lufenuron

5. Kusunga masamba

Cholinga chachikulu chakupha tizilombo ndikuteteza kuti tizirombo zisawononge mbewu.Ponena za kuthamanga ndi kufa kwapang'onopang'ono kwa tizirombo kapena kupitilira apo, kuchuluka kwa chitetezo chamasamba ndi index yomaliza yoyezera mtengo wazinthu.

Poyerekeza ndi mphamvu ya kuwongolera kwa wodzigudubuza masamba a mpunga, kusungidwa kwa masamba kwa louciacaride ndi fenfenitrile kunafika kupitirira 90% ndi pafupifupi 65%, motero.

Chifukwa chake, molingana ndi kuchuluka kwa kasungidwe kwa masamba, kuyerekeza ndi: Chlorfenapyr> Lufenuron

6. Chitetezo

Mpaka pano, palibe chomwe chachitika ndi mankhwala ophera tizilombo.Panthawi imodzimodziyo, mankhwala ophera tizilombo sangayambitse kufalikira kwa tizirombo tobaya ndi kuyamwa, ndipo imakhala ndi zotsatira zochepa pa akuluakulu a tizilombo tothandiza komanso akangaude olusa.

Chlorfenapyr imakhudzidwa ndi masamba a cruciferous ndi mavwende, ndipo imatha kuwononga mankhwala ikagwiritsidwa ntchito pa kutentha kwambiri kapena mlingo waukulu.

Choncho, kuyerekezera chitetezo ndi: Lufenuron> Chlorfenapyr
