Kulesi sikhathi sonyaka ngamunye, kuqubuka inani elikhulu lezinambuzane (i-army bug, i-Spodoptera littoralis, i-Spodoptera litura, i-Spodoptera frugiperda, njll.), okubangela umonakalo omkhulu ezitshalweni. Njengesithako esibulala izinambuzane esibanzi, i-chlorfenapyr inomphumela omuhle wokulawula kulezi zinambuzane.
1. Izici ze-chlorfenapyr
(1) I-Chlorfenapyr inezinhlobo eziningi zemithi yokubulala izinambuzane kanye nezindlela eziningi zokusebenzisa. Ingasetshenziswa ukulawula izinhlobo eziningi zezinambuzane ezifana ne-Lepidoptera ne-Homoptera emifinweni, ezihlahleni zezithelo, nasezitshalweni zasensimini, njenge-diamondback moth, i-cabbage worm, i-beet armyworm, kanye ne-twill. Izinambuzane eziningi zemifino ezifana ne-noctuid moth, i-cabbage borer, i-cabbage aphid, i-leafminer, i-thrips, njll., ikakhulukazi ngokumelene nezinambuzane ezindala ze-Lepidoptera, zisebenza kahle kakhulu.
(2) I-Chlorfenapyr inobuthi esiswini kanye nemiphumela yokubulala izinambuzane. Iyakwazi ukungena kahle ebusweni beqabunga, inomphumela othile ohlelekile, futhi inezici zobubanzi bokubulala izinambuzane, umphumela wokulawula ophezulu, umphumela ohlala isikhathi eside kanye nokuphepha. Ijubane lokubulala izinambuzane liyashesha, ukungena kunamandla, futhi umuthi wokubulala izinambuzane uphelele. (Izinambuzane zingabulawa zingakapheli ihora elilodwa ngemva kokufutha, futhi ukusebenza kahle kokulawula kosuku kungafinyelela ngaphezu kuka-85%).
(3) I-Chlorfenapyr inamandla okulawula izinambuzane ezimelana nezinambuzane, ikakhulukazi izinambuzane nezibungu ezimelana nezinambuzane ezifana ne-organophosphorus, i-carbamate, kanye ne-pyrethroids.
2. Ukuxuba i-chlorfenapyr
Nakuba i-chlorfenapyr inezinhlobo eziningi zemithi yokubulala izinambuzane, umphumela wayo muhle, futhi ukumelana kwamanje kuphansi kakhulu. Kodwa-ke, noma yiluphi uhlobo lwe-ejenti, uma lusetshenziswa lodwa isikhathi eside, ngokuqinisekile luzoba nezinkinga zokumelana esigabeni esilandelayo.
Ngakho-ke, ekufuthweni kwangempela, i-chlorfenapyr kufanele ivame ukuhlanganiswa neminye imithi ukuze inciphise ukukhiqizwa kokumelana nemithi futhi ithuthukise umphumela wokulawula.
(1) Inhlanganisela yei-chlorfenapyr + i-emamectin
Ngemva kokuhlanganiswa kwe-chlorfenapyr ne-emamectin, inezinhlobo eziningi zemithi yokubulala izinambuzane, futhi ingalawula ama-thrips, izimbungulu ezinukayo, izimbungulu ezinamaqabunga, izicabucabu ezibomvu, izibungu zenhliziyo, izibungu zommbila, izibungu zeklabishi nezinye izinambuzane emifinweni, emasimini, ezihlahleni zezithelo nakwezinye izitshalo.
Ngaphezu kwalokho, ngemva kokuxuba i-chlorfenapyr ne-emamectin, isikhathi esihlala isikhathi eside somuthi siba side, okuzuzisa ukunciphisa imvamisa yokusebenzisa umuthi nokunciphisa izindleko zokusebenzisa zabalimi.
Isikhathi esingcono kakhulu sokufaka: esigabeni sezinkanyezi ezingu-1-3 zezinambuzane, lapho umonakalo wezinambuzane ensimini ungaba ngu-3%, futhi izinga lokushisa lilawulwa cishe kuma-degrees angu-20-30, umphumela wokufaka uba ngcono kakhulu.
(2) i-chlorfenapyr +i-indoxacarb exutshwe ne-indoxacarb
Ngemva kokuxuba i-chlorfenapyr ne-indoxacarb, ayikwazi nje ukubulala izinambuzane ngokushesha (izinambuzane zizoyeka ukudla ngokushesha ngemva kokuthinta umuthi wokubulala izinambuzane, futhi izinambuzane zizofa zingakapheli izinsuku ezingu-3-4), kodwa futhi igcina ukusebenza kahle isikhathi eside, okuyinto efaneleka kakhulu ezitshalweni. Ukuphepha.
Ingxube ye-chlorfenapyr ne-indoxacarb ingasetshenziswa ukulawula izinambuzane ze-lepidopteran, njenge-cotton bollworm, iklabishi caterpillar yezitshalo ze-cruciferous, i-diamondback moth, i-beet armyworm, njll., ikakhulukazi ukumelana ne-noctuid moth kuyamangalisa.
Kodwa-ke, uma lezi zinto ezimbili zixutshwe, umphumela emaqandeni awubi muhle. Uma ufuna ukubulala amaqanda kanye namadala, ungasebenzisa i-lufenuron ndawonye.
Isikhathi esingcono kakhulu sokusetshenziswa: ezigabeni eziphakathi nasekupheleni kokukhula kwezitshalo, lapho izinambuzane sezikhulile, noma lapho izizukulwane zezinambuzane zesibili, zesithathu, nezesine zixubene, umphumela womuthi uba muhle.
(3)i-chlorfenapyr + abamectin compound
I-Abamectin ne-chlorfenapyr zihlanganiswe nomphumela ocacile wokubambisana, futhi ziyasebenza ngokumelene nama-thrips amelana kakhulu, izibungu, i-beet armyworm, kanye ne-leek. Zonke zinemiphumela emihle yokulawula.
Isikhathi esingcono kakhulu sokuyisebenzisa: ezigabeni eziphakathi nasekupheleni kokukhula kwezitshalo, lapho izinga lokushisa liphansi emini, umphumela uba ngcono. (Uma izinga lokushisa liphansi kunama-degrees angu-22, umsebenzi wokubulala izinambuzane we-abamectin uphakeme).
(4) Ukusetshenziswa okuxubile kwe-chlorfenapyr + okunyeizibulala-zinambuzane
Ngaphezu kwalokho, i-chlorfenapyr ingaxutshwa ne-thiamethoxam, i-bifenthrin, i-tebufenozide, njll. ukulawula ama-thrip, ama-diamondback moth nezinye izinambuzane.
Uma kuqhathaniswa neminye imithi: i-chlorfenapyr isetshenziswa kakhulu ukulawula izinambuzane ze-lepidopteran, kodwa ngaphezu kwe-chlorfenapyr, kuneminye imithi emibili enemiphumela emihle yokulawula izinambuzane ze-lepidopteran, okuyi-lufenuron kanye ne-indene Wei.
Ngakho-ke, uyini umehluko phakathi kwale mithi emithathu? Kufanele sikhethe kanjani umuthi ofanele?
Laba bameli abathathu banezinzuzo nezinkinga zabo. Ezisetshenzisweni ezingokoqobo, singakhetha i-ejenti efanele ngokwesimo sangempela.
