Yimuphi umphumela wesibulala-zinambuzane onamandla, i-Lufenuron noma i-Chlorfenapyr?

I-Lufenuron

I-Lufenuron iwuhlobo lokusebenza kahle kakhulu, i-spectrum ebanzi kanye nesibulala-zinambuzane esinobuthi obuphansi ukuvimbela ukuncibilika kwezinambuzane.Ikakhulukazi inobuthi besisu, kodwa futhi inomphumela othile wokuthinta.Ayinayo intshisekelo yangaphakathi, kodwa inomphumela omuhle.Umphumela we-Lufenuron ezibungwini ezincane muhle kakhulu.Ngemuva kokudla izitshalo ezifuthwe ngesibulala-zinambuzane, izinambuzane ziyeka ukudla amahora angu-2 bese zingena esiqongweni sezinambuzane ezifile ezinsukwini ezingu-2-3.

Iphephile ezitheni eziningi zemvelo ngenxa yokusebenza kwayo kancane kanye nesikhathi eside sokusebenza.

I-Chlorfenapyr

I-Chlorfenapyr inomphumela othile emsebenzini we-ovicidal.Kuhlanganiswe nokubikezela kanye nokubikezela kwezinambuzane, kuphakanyiswa ukuthi isifutho singadlala umphumela omuhle wokulawula lapho kuchanyuselwa izinambuzane noma ukuchanyuselwa kwamaqanda.

I-Chlorfenapyr ine-conductivity enhle yendawo ezitshalweni, futhi umphumela ofanayo ungatholakala ngaphansi kwamaqabunga anikezwa izinambuzane.

Umphumela wokulawula ungama-90-100% phakathi kwezinsuku ezingu-L-3 ngemva komuthi, futhi umphumela usalokhu uzinzile ku-90% phakathi kwezinsuku ezingu-15 ngemva komuthi.Umthamo onconyiwe ngu-30-40 ml imu ngayinye, nesikhawu sezinsuku eziyi-15-20.

Ukunakwa okukhethekile kufanele kukhokhwengenkathi usebenzisa i-Chlorfenapyr:

1) Iyazwela kukhabe, izucchini, ukhamba olubabayo, ikhabe, i-cantaloupe, ukhamba olumhlophe, ithanga, i-cantaloupe, i-loofah nezinye izitshalo.Akunconyiwe esigabeni samaqabunga amancane.

2) Gwema ukusebenzisa izidakamizwa ezingeni lokushisa eliphezulu, izimbali isigaba kanye yisithombo esiteji;

Umehluko phakathiChlorfenapyr kanyeI-Lufenuron

1. Izindlela zokubulala izinambuzane

I-Lufenuron inomphumela wobuthi besisu nokuthinta, akukho ukulangazelela kwangaphakathi, ukubulawa kweqanda elinamandla;

I-Chlorfenapyr inobuthi besisu kanye nokuthinta, futhi inokumuncwa okuthile kwangaphakathi.

Ukusetshenziswa kwe-osmotic/extender agents (isb, i-silicone) kuzokwandisa kakhulu ukusebenza kahle kokubulala.

2. Insecticidal spectrum

Isetshenziswa kakhulu ekulawuleni i-leaf roller, i-Plutella xylostella, i-Rapeseed, i-beet armyworm, i-Spodoptera litura, i-whitefly, i-thrips, imikhaza yokugqwala nezinye izinambuzane, ikakhulukazi ekulawuleni i-rice leaf roller.

I-Lufenuron inomphumela omuhle kakhulu wokulawula izinambuzane nezibungu, ikakhulukazi ezinambuzaneni ezimelana nezifo ezifana ne-Plutella xylostella, i-Exigua beet armyworm, i-Exigua chinensis, i-leaf roller, i-American spot miner, i-pod borer, ama-thrips nesicabucabu esinenkanyezi.

Ngakho-ke, umehluko obanzi ngokuya nge-spectrum ye-insecticidal yile: Chlorfenapyr > Lufenuron > Indoxacarb

3, Ijubane lokubulala

Izinambuzane ezithintana ne-pesticide futhi zidla amaqabunga nge-pesticide, umlomo uzokhishwa izinzwa kungakapheli amahora angu-2, uyeke ukudla, ukuze umise ukulimaza izitshalo, izinsuku ezingu-3-5 ukufinyelela inani eliphakeme lezinambuzane ezifile;

Ihora elilodwa ngemva kokwelashwa kwe-fenfenitrile nge-insecticide, umsebenzi wezinambuzane waba buthakathaka, amabala avela, umbala washintsha, umsebenzi wama, i-coma, i-coma, futhi ekugcineni yaholela ekufeni, futhi inani eliphakeme lezinambuzane ezifile lafinyelelwa emahoreni angu-24.

Ngakho-ke, ngokusho kwejubane le-insecticidal, ukuqhathanisa: Chlorfenapyr > Lufenuron

4. Isikhathi sokugcina

I-Lufenuron inomphumela oqinile we-ovicidal, futhi isikhathi sokulawula izinambuzane side kakhulu, kufika ezinsukwini ezingu-25;

I-Chlorfenapyr ayiwabulali amaqanda, kodwa iphumelela kuphela ezinambuzaneni esezikhulile, futhi isikhathi sokulawula siyizinsuku ezingama-7-10.

I-Chlorfenapyr > Lufenuron

5. Izinga lokugcinwa kwamaqabunga

Inhloso enkulu yokubulala izinambuzane ukuvimbela izinambuzane ekulimazeni izitshalo.Ngokuqondene nesivinini nokufa okuhamba kancane kwezinambuzane noma ngaphezulu nangaphansi, izinga lezinga lokuvikelwa kwamaqabunga liyinkomba yokugcina yokukala inani lemikhiqizo.

Uma kuqhathaniswa nomphumela wokulawula we-rice leaf roller, izinga lokulondolozwa kweqabunga le-louciacaride ne-fenfenitrile lifinyelele ngaphezu kwama-90% futhi cishe ama-65%, ngokulandelana.

Ngakho-ke, ngokwezinga lokugcinwa kwamaqabunga, ukuqhathanisa: Chlorfenapyr > Lufenuron

6. Ukuphepha

Kuze kube manje, akukho ukusabela kwezinambuzane.Ngesikhathi esifanayo, i-insecticide ngeke ibangele ukwanda kwezinambuzane ezigwazayo nokumunca, futhi inomphumela omncane kubantu abadala bezinambuzane ezizuzisayo kanye nezicabucabu ezizingelayo.

I-Chlorfenapyr izwela imifino namakhabe e-cruciferous, futhi ingabangela ukulimala kwezidakamizwa lapho isetshenziswa ezingeni lokushisa eliphezulu noma ngethamo eliphezulu.

Ngakho-ke, ukuqhathanisa kokuphepha yilokhu: Lufenuron > Chlorfenapyr
