Kule sizini yonyaka ngamunye, kuqubuka inqwaba yezinambuzane (imbungulu yebutho, iSpodoptera littoralis, iSpodoptera litura, iSpodoptera frugiperda, njll.), edala umonakalo omkhulu ezitshalweni.Njenge-ejenti ebulala izinambuzane ebanzi, i-chlorfenapyr inomphumela omuhle wokulawula lezi zinambuzane.
1. Izici ze-chlorfenapyr
(1) I-Chlorfenapyr ine-spectrum ebanzi yezibulala-zinambuzane kanye nohlu olubanzi lwezinhlelo zokusebenza.Ingasetshenziswa ukulawula izinhlobo eziningi zezinambuzane ezifana ne-Lepidoptera ne-Homoptera emifino, ezihlahleni zezithelo, nasezitshalweni zasensimini, njengenundu le-diamondback, i-cabbage worm, i-beet armyworm, ne-twill.Izinambuzane eziningi zemifino ezifana ne-noctuid moth, iklabishi borer, i-aphid yeklabishi, i-leafminer, ama-thrips, njll., ikakhulukazi kubantu abadala bezinambuzane ze-Lepidoptera, zisebenza kakhulu.
(2) I-Chlorfenapyr inoshevu wesisu kanye nemiphumela yokubulala othintana naye ezinambuzaneni.Inokungena okuqinile endaweni yamaqabunga, inomphumela othile wesistimu, futhi inezici ze-spectrum ebanzi yezinambuzane, umphumela wokulawula ophezulu, umphumela ohlala isikhathi eside nokuphepha.Ijubane lokubulala izinambuzane liyashesha, ukungena kunamandla, futhi isibulala-zinambuzane siphelele.(Izilokazane zingabulawa phakathi nehora elingu-1 ngemva kokufafaza, futhi ukusebenza kahle kokulawula kosuku kungafinyelela ngaphezu kwama-85%).
(3) I-Chlorfenapyr inomphumela wokulawula ophezulu ngokumelene nezinambuzane ezimelana nezinambuzane, ikakhulukazi izinambuzane nezibungu ezimelana nezibulala-zinambuzane ezifana ne-organophosphorus, carbamate, ne-pyrethroids.
2. Ukuxuba i-chlorfenapyr
Nakuba i-chlorfenapyr ine-spectrum ebanzi yezibulala-zinambuzane, umphumela nawo muhle, futhi ukumelana kwamanje kuphansi.Kodwa-ke, noma yiluphi uhlobo lwe-ejenti, uma lusetshenziswa lulodwa isikhathi eside, nakanjani luyoba nezinkinga zokungazweli esigabeni sakamuva.
Ngakho-ke, ekufutheni kwangempela, i-chlorfenapyr kufanele ivamise ukuxutshwa neminye imithi ukuze kwehliswe isizukulwane sokungazweli emthini futhi kuthuthukiswe umphumela wokulawula.
(1) Inhlanganisela yeI-chlorfenapyr + emamectin
Ngemva kokuhlanganiswa kwe-chlorfenapyr kanye ne-emamectin, inezinhlobo eziningi zezibulala-zinambuzane, futhi ingakwazi ukulawula ama-thrips, izimbungulu ezinukayo, amabhungane, izicabucabu ezibomvu, ama-heartworms, ama-corn borer, amacimbi eklabishi nezinye izinambuzane emifino, amasimu, izihlahla zezithelo nezinye izitshalo. .
Ngaphezu kwalokho, ngemva kokuxuba i-chlorfenapyr ne-emamectin, isikhathi esihlala njalo se-medicament side, okuzuzisa ukunciphisa imvamisa yokusebenzisa umuthi nokunciphisa izindleko zokusebenzisa abalimi.
Isikhathi esihle kakhulu sokufaka isicelo: esigabeni esingu-1-3 sokuqala sezinambuzane, lapho umonakalo wezinambuzane ensimini cishe u-3%, futhi izinga lokushisa lilawulwa cishe ngama-20-30 degrees, umphumela wokufaka isicelo ungcono kakhulu.
(2) i-chlorfenapyr +indoxacarb exutshwe ne-indoxacarb
Ngemuva kokuxuba i-chlorfenapyr ne-indoxacarb, ayikwazi nje ukubulala izinambuzane ngokushesha (izinambuzane zizoyeka ukudla ngokushesha ngemva kokuthintana ne-pesticide, futhi izinambuzane zizofa phakathi kwezinsuku ezingu-3-4), kodwa futhi zigcine ukusebenza kahle isikhathi eside, okungukuthi. futhi ifaneleka kakhulu izitshalo.Ukuphepha.
Ingxube ye-chlorfenapyr kanye ne-indoxacarb ingasetshenziswa ukulawula izinambuzane ze-lepidopteran, ezifana ne-cotton bollworm, isibungu seklabishi sezitshalo ze-cruciferous, inundu ye-diamondback, i-beet armyworm, njll., ikakhulukazi ukumelana nebhu le-noctuid kuyaphawuleka.
Kodwa-ke, lapho lawa ma-ejenti amabili exutshwa, umthelela emaqanda awumuhle.Uma ufuna ukubulala amaqanda kanye nabantu abadala, ungasebenzisa i-lufenuron ndawonye.
Isikhathi esihle kakhulu sokufaka isicelo: phakathi nezigaba ezimaphakathi nezakamuva zokukhula kwezitshalo, lapho izinambuzane sezikhulile, noma lapho isizukulwane sesi-2, sesi-3, nesi-4 sezinambuzane zixutshwa, umphumela womuthi muhle.
(3)i-chlorfenapyr + abamectin compound
I-Abamectin ne-chlorfenapyr kuhlanganiswe nomphumela osobala we-synergistic, futhi iyasebenza ngokumelene nama-thrips amelana kakhulu, amacimbi, i-beet armyworm, i-leek Konke kunemiphumela emihle yokulawula.
Isikhathi esingcono kakhulu sokuyisebenzisa: ezigabeni ezimaphakathi nezakamuva zokukhula kwezitshalo, lapho izinga lokushisa liphansi phakathi nosuku, umphumela uba ngcono.(Lapho izinga lokushisa lingaphansi kuka-22 degrees, umsebenzi wokubulala izinambuzane we-abamectin uphakeme).
(4) Ukusetshenziswa okuxubile kwe-chlorfenapyr + nokunyeizibulala-zinambuzane
Ngaphezu kwalokho, i-chlorfenapyr ingabuye ixutshwe ne-thiamethoxam, i-bifenthrin, i-tebufenozide, njll. ukulawula ama-thrips, amabhu e-diamondback nezinye izinambuzane.
Uma kuqhathaniswa nezinye izidakamizwa: i-chlorfenapyr isetshenziselwa kakhulu ukulawula izinambuzane ze-lepidopteran, kodwa ngaphezu kwe-chlorfenapyr, kunezinye izidakamizwa ezimbili ezibuye zibe nemiphumela emihle yokulawula izinambuzane ze-lepidopteran, okuyi-lufenuron ne-indene Wei.
Ngakho-ke, yini umehluko phakathi kwale mithi emithathu?Kufanele siwukhethe kanjani umuthi ofanele?
Lawa ma-ejenti amathathu anezinzuzo zawo kanye nokubi.Kuzinhlelo zokusebenza ezisebenzayo, singakhetha i-ejenti efanele ngokuya ngesimo sangempela.
