Muri iki gihembwe cya buri mwaka, udukoko twinshi twaduka (udusimba twingabo, Spodoptera littoralis, Spodoptera litura, Spodoptera frugiperda, nibindi), byangiza cyane ibihingwa.Nkumuti mugari wica udukoko twica udukoko, chlorfenapyr igira ingaruka nziza zo kurwanya udukoko.
1. Ibiranga chlorfenapyr
(1) Chlorfenapyr ifite ubwinshi bwimiti yica udukoko hamwe nuburyo bwinshi bwo gukoresha.Irashobora gukoreshwa mu kurwanya ubwoko bwinshi bw’udukoko nka Lepidoptera na Homoptera ku mboga, ibiti byera imbuto, n’ibihingwa byo mu murima, nk'inyenzi ya diyama, inyo ya cabage, inzoka za beterave, na twill.Udukoko twinshi twimboga nkinyenzi za noctuid, borer cabage, cabage aphid, leafminer, thrips, nibindi, cyane cyane kubantu bakuze by’udukoko twa Lepidoptera, bifite akamaro kanini.
(2) Chlorfenapyr ifite uburozi bwigifu no guhura kwica udukoko.Ifite uburyo bworoshye bwo kwinjirira hejuru yamababi, ifite ingaruka zifatika, kandi ifite ibiranga imiti myinshi yica udukoko, ingaruka zo kugenzura cyane, ingaruka ndende n'umutekano.Umuvuduko wica udukoko urihuta, kwinjira birakomeye, kandi umuti wica udukoko urasa neza.(Udukoko turashobora kwicwa mugihe cyisaha 1 nyuma yo gutera, kandi umunsi wo kurwanya umunsi urashobora kugera kuri 85%).

2. Kuvanga chlorfenapyr
Nubwo chlorfenapyr ifite udukoko twinshi twica udukoko, ingaruka nazo ni nziza, kandi kurwanya ubu ni bike.Nyamara, ubwoko ubwo aribwo bwose, niba bukoreshejwe wenyine igihe kirekire, byanze bikunze bizagira ibibazo byo guhangana nicyiciro cyanyuma.
Kubwibyo, mu gutera nyirizina, chlorfenapyr igomba kuvangwa nindi miti kugirango igabanye umuvuduko wo kurwanya ibiyobyabwenge no kunoza ingaruka zo kugenzura.
(1) Igiteranyo cyachlorfenapyr + emamectin
Nyuma yo guhuza chlorfenapyr na emamectin, ifite imiti myinshi yica udukoko, kandi irashobora kurwanya thrips, udukoko tunuka, inyenzi zo mu bwoko bwa fla, ibitagangurirwa bitukura, inzoka zo mu mutima, ibigori byangiza, imyumbati yangiza nudukoko twangiza ku mboga, imirima, ibiti byimbuto nibindi bihingwa. .
Byongeye kandi, nyuma yo kuvanga chlorfenapyr na emamectin, igihe kirambye cyimiti ni kirekire, kikaba ari ingirakamaro kugabanya inshuro zo gukoresha imiti no kugabanya igiciro cy’imikoreshereze y’abahinzi.
Igihe cyiza cyo kubishyira mu bikorwa: mugice cya 1-3 instar yudukoko, mugihe ibyonnyi byangiza mumurima bigera kuri 3%, kandi ubushyuhe bugenzurwa kuri dogere 20-30, ingaruka zo kubishyira nibyiza.
(2) chlorfenapyr +indoxacarb ivanze na indoxacarb
Nyuma yo kuvanga chlorfenapyr na indoxacarb, ntishobora kwica udukoko vuba gusa (udukoko tuzahagarika kurya ako kanya nyuma yo guhura nudukoko twangiza udukoko, kandi ibyonnyi bizapfa muminsi 3-4), ariko kandi bikomeza gukora neza mugihe kirekire, aribyo bikwiriye kandi cyane kubihingwa.Umutekano.
Uruvange rwa chlorfenapyr na indoxacarb rushobora gukoreshwa mu kurwanya udukoko twitwa lepidopteran, nka pamba bollworm, caterpillar caterpillar y ibihingwa byingirakamaro, inyenzi za diyama, inyenzi za beterave, nibindi, cyane cyane kurwanya inyenzi za noctuid.
Ariko, mugihe ibyo bintu byombi bivanze, ingaruka kumagi ntabwo ari nziza.Niba ushaka kwica amagi n'abantu bakuru, urashobora gukoresha lufenuron hamwe.
Igihe cyiza cyo kubishyira mu bikorwa: mugihe cyo hagati nicyanyuma cyo gukura kwibihingwa, mugihe udukoko tumaze gukura, cyangwa mugihe ibisekuru bya 2, 3, na 4 byudukoko bivanze, ingaruka zimiti nibyiza.
Abamectin na chlorfenapyr byongewemo ningaruka zigaragara, kandi bifite akamaro mukurwanya thrips, caterpillars, beet armyworm, leek Byose bifite ingaruka nziza zo kugenzura.
Igihe cyiza cyo kugikoresha: mugihe cyo hagati no gutinda gukura kwibihingwa, iyo ubushyuhe buri munsi kumunsi, ingaruka ni nziza.(Iyo ubushyuhe buri munsi ya dogere 22, ibikorwa byica udukoko twa abamectin biri hejuru).
(4) Gukoresha kuvanga chlorfenapyr + ibindiimiti yica udukoko
Byongeye kandi, chlorfenapyr irashobora kandi kuvangwa na thiamethoxam, bifenthrin, tebufenozide, nibindi kugirango igabanye thrips, inyenzi za diyama nizindi udukoko.
Ugereranije n’ibindi biyobyabwenge: chlorfenapyr ikoreshwa cyane cyane mu kurwanya udukoko twa lepidopteran, ariko usibye chlorfenapyr, hari indi miti ibiri nayo igira ingaruka nziza zo kurwanya udukoko twa lepidopteran, twavuga nka lufenuron na indene Wei.
None, ni irihe tandukaniro riri hagati yiyi miti itatu?Nigute dushobora guhitamo imiti ikwiye?
Izi mikorere uko ari eshatu zifite ibyiza byazo nibibi.Mubikorwa bifatika, turashobora guhitamo umukozi ubikurikije uko ibintu bimeze.
