I-High Qaulity Insecticide Methoprene 95%TC enenani elingcono kakhulu

Incazelo Yomkhiqizo

Kuyi-insecticide ye-biochemical ye-insect juvenile hormone class.I-hormone yengane yezinambuzane ingalawula ukukhula kwayo, ukuthuthukiswa, kanye nenqubo ye-metamorphosis.Umsebenzi oyinhloko we-hormone yezingane ukuvimbela ukuguquguquka kwezibungu ezingavuthiwe, ukugcina izici zesiteji sezinambuzane zezinambuzane, nokuhlala izibungu ngemva kokubola.

I-Methoprene, njenge-agent evikelayo yamaqabunga kagwayi, iphazamisa inqubo yokucwecwa kwezinambuzane.Kungaphazamisa ukukhula kanye nenqubo yokuthuthukiswa kwamabhungane kagwayi kanye nama-powder borer, okwenza izinambuzane ezindala zilahlekelwe amandla azo okuzala, ngaleyo ndlela zilawule ngempumelelo ukukhula kwenani lezinambuzane ezigciniwe zamaqabunga kagwayi.

Isicelo

Amahomoni ezinambuzane ezingane awakwazi ukubulala izinambuzane ngokuqondile, angabangela kuphela ukuthi zife ngesikhathi sokushintshashintsha, noma ukunciphisa inani lenzalo ngenxa yokungazali noma ukungachanyuselwa amaqanda.Ngakho-ke, imiphumela yabo ihamba kancane futhi ayikwazi ukulawula ngokushesha ukulimala kwezinambuzane eziqhumayo, inciphisa ukusetshenziswa kwazo kwezolimo.Njengamanje, isetshenziswa ikakhulukazi ezicini ezilandelayo:

1. Ukuvimbela nokulawula izinambuzane zezempilo.I-Fenpropathrin inomsebenzi ophezulu ngokumelene namaphela aseJalimane futhi ingabangela ukungazali kokubili kwabesifazane nabesilisa abadala.Ukuqhubeka nokwelapha ngalo muthi kungenza uphele ngenxa yokungazali ngemva kwezinyanga eziyisithupha kuya onyakeni, futhi uyasebenza nasemakhazeni amakhulu.Ukwenza i-ejenti ekhishwa isikhathi eside ye-methoprene kuyasebenza futhi ekuvimbeleni nasekwelapheni amazeze, omiyane, nezimpukane.

2. Lawula izinambuzane ze-Hemiptera.I-Fenvalerate iyasebenza ekulawuleni ama-greenhouse aphid nezimpukane ezimhlophe futhi ibhaliswe e-United States.Kodwa ukuzinza akukuhle uma kusetshenziswe ensimini.I-Dioxycarb iyasebenza ekulawuleni izimpukane ezimhlophe kanye nama-crustaceans.

3. Ukuvimbela nokulawula izinambuzane eziwugcinayo.I-hormone yentsha inomsebenzi ophezulu ngokumelene nezinambuzane ze-Lepidoptera ngesikhathi sokugcinwa, okufana nokusanhlamvu, ufulawa, nogwayi.E-United States, ihlolwe ukuthi iyasebenza ngokumelene nezinambuzane eziningi zokugcina, njenge-fenpropathrin ne-carbendazim.

4. Ukuvimbela nokulawula izintuthwane.I-Fenpropathrin bait ingavimbela ukuguquguquka okujwayelekile kwezibungu eziyingozi, yenze inkosi yezintuthwane ingabi magciwane, futhi ilawule ngempumelelo izintuthwane zasekhishini.Kukhona nemibiko yokusebenzisa amahomoni ezingane ukwelapha umuhlwa.

5. Khulisa ukukhiqizwa kukasilika.Ukufafaza i-hormone yezingane noma i-pseudojuvenile hormone njenge-anti-hormone yengane esihlalweni sosilika (2-4 micrograms/ikhanda) noma emzimbeni wesibungu we-5th instar (1-3 micrograms/ikhanda) kungavimbela ukwakheka kwe-metamorphosis, andise isigaba sesi-5 sesibungu ngokungaphezulu. kunosuku olulodwa, ukwandisa ukudla, ukwandisa ubukhulu bomuntu ngamunye, futhi andise ukukhiqizwa kukasilika.Ngokuvamile, ingakhuphula inani lama-cocoon ayi-10000 cishe ngo-15%.

Ukusebenzisa Izindlela

1. Gcina amahlamvu kagwayi ukuze uvimbele amabhungane.Fafaza impushana encibilikayo engu-41% izikhathi ezingu-40000 zoketshezi emaqabunga kagwayi.Ukuqinisekisa isifutho esifanayo kanye nokumbozwa okuphelele kwamaqabunga kagwayi, ukuhlanjululwa komthamo noma imishini ekhethekile ye-multi-directional ultra-low volume spray ingasetshenziswa.

2. Ukuzwela kwezinambuzane kumahomoni ezingane kuyahlukahluka ezigabeni ezihlukene zokukhula nokukhula.Izibungu noma i-nymph zizwela kakhulu esigabeni sokugcina, kanti ezinye izigaba azizweli kakhulu.Enqubweni yokukhula nokuthuthukiswa kwezinambuzane, isikhathi esifanele siyakhethwa futhi ama-hormone ezingane angaphandle asetshenziselwa ukuphazamisa ibhalansi ye-hormone evamile emzimbeni wezinambuzane, okubangela ukuguquguquka okungavamile, ukungazali kwabantu abadala, noma ukungakwazi ukuchamusela amaqanda, ngaleyo ndlela kufinyelele umgomo wokulawula nokulawula. ukuqeda izinambuzane.

3. I-IC50 fenvalerate ye-Culex pipiens izibungu ingu-0.48 micrograms ilitha, kanti i-ID50 fenvalerate ye-wax moth pupae ingama-micrograms angu-2.2 isiphungumangathi ngasinye.
