Umphumela Wokusetshenziswa Kwe-Chlorempenthrin

I-Chlorempenthrinuhlobo olusha lwesibulala-zinambuzane se-pyrethroid esisebenza kahle kakhulu futhi sinobuthi obuphansi, esinomphumela omuhle komiyane, izimpukane namaphela. Sinezici zokucindezela okuphezulu komhwamuko, ukuguquguquka okuhle kanye namandla okubulala aqinile, futhi isivinini sokuqeda izinambuzane siyashesha, ikakhulukazi ekufuthweni nasekufuthweni.

Indlela yokusebenzisa

1. Ukulawulwa kwezinambuzane zikakotini

(1) Ukuvimbela nokulawula i-cotton bollworm: ukusetshenziswa komuthi ngesikhathi sokufukamela amaqanda, ukhilimu we-bifenthrin ongu-10% 23 ~ 40ml nge-mu yamanzi 50 ~ 60kg spray, 7 ~ 10d ngemuva komuthi unomphumela omuhle wokubulala izinambuzane kanye nokuvikela amahlumela. Lo mthamo ungasetshenziswa futhi ukulawula i-cotton bollworm. Isikhathi esifanele sokuvimbela nokwelapha yisizukulwane sesibili nesesithathu sokufukamela amaqanda, futhi isizukulwane ngasinye selashwa kabili.

(2) Ukuvimbela nokwelashwa kwezibungu zamaqabunga kakotini: Uma izibungu zisetshenziswa esigabeni sokuvela kwazo, ukhilimu ongu-10% ongu-30 ~ 40ml nge-mu yamanzi angu-50 ~ 60kg, isikhathi esisele esingaba yizinsuku eziyi-12, singalapha nezibungu zamakhambi, izibungu zamakhambi, izibungu zamakhambi, ama-thrips, njll. (njengalapho kunikezelwe ekuvimbeleni nasekwelapheni izibungu zamakhambi, umthamo ungancishiswa ngesigamu).

2. Lawula izinambuzane zezihlahla zezithelo

(1) Ukuvimbela nokwelashwa kwe-peachworm: faka umuthi lapho iqanda liqala ukufukamela, lapho izinga lezithelo zamaqanda lifinyelela ku-0.5% ~ 1%, sebenzisa i-10% bifenthrin emulsion 3300 ~ 4000 izikhathi zokufutha ngoketshezi. Ukufutha izikhathi ezintathu kuya kwezine kuyo yonke isizini kungalawula ngempumelelo ukulimala kwayo, futhi isikhathi somphumela osele singaba yizinsuku eziyi-10.

(2) Ukuvimbela nokwelapha izimbuzane zamaqabunga e-apula: ngaphambi noma ngemva kokuqhakaza kwe-apula, esigabeni sokukhula futhi uma izimbuzane zenzeka, lapho iqabunga ngalinye linezimbuzane ezimbili ngokwesilinganiso, faka umuthi, bese ufutha ngokhilimu ongu-10% izikhathi ezingu-3300 ~ 5000. Uma umlomo wezimbuzane uphansi, isikhathi somphumela osele sasiyizinsuku ezingu-24 kuya kwezingu-28. Ingasetshenziswa futhi ukulawula abavukuzi bamaqabunga kanye nezimbuzane zamaqabunga abomvu kwezinye izihlahla zezithelo.

3. Lawula izinambuzane zemifino

(1) Ukulawulwa kwempukane emhlophe: Esigabeni sokuqala sokuvela kwempukane emhlophe, inani lezinambuzane aliphezulu.

(2) Mayelana nekhanda/isitshalo, umthamo uwukuthi: ukhukhamba notamatisi abatshalwe endaweni eshisayo abanezithako ezisebenzayo ezingu-2 ~ 2.5g nge-mu yesifutho esingu-50kg emanzini, abavulelwe ngezithako ezisebenzayo ezingu-2.5 ~ 4g nge-mu yesifutho esingu-50kg emanzini, bangalawula ngempumelelo umonakalo wabo zingakapheli izinsuku ezingu-15. Uma inani lezinambuzane liphezulu, umphumela wokulawula wesilinganiso esifanayo awuzinzile.

(3) Ukuvimbela nokwelashwa kwe-aphid: faka umuthi ngesikhathi sokuvela, sebenzisa uwoyela we-bifenthrin oxutshwayo ongu-10% izikhathi ezingu-3000 ~ 4000, ungalawula umonakalo, isikhathi esisele singaba ngu-15d. Lo mthamo ungalawula nezinhlobonhlobo zezinambuzane ezidla amaqabunga, njengezimpethu zeklabishi, i-diamond moth njalo njalo.
