Sehleng sena sa selemo se seng le se seng, palo e kholo ea likokoanyana e qhoma (army bug, Spodoptera littoralis, Spodoptera litura, Spodoptera frugiperda, jj.), e bakang tšenyo e kholo lijalong. Jwalo ka moemeli oa ho bolaea likokoanyana oa mefuta e mengata, chlorfenapyr e na le phello e ntle ea taolo ho likokoanyana tsena.
1. Litšobotsi tsa chlorfenapyr
(1) Chlorfenapyr e na le mefuta e mengata ea meriana e bolaeang likokoanyana le mefuta e mengata ea ts'ebeliso. E ka sebelisoa ho laola mefuta e mengata ea likokoanyana tse kang Lepidoptera le Homoptera merohong, lifateng tsa litholoana le lijalong tsa masimo, joalo ka diamondback moth, cabbage worm, beet armyworm, le twill. Tse ngata tse senyang lijalo tse kang noctuid moth, cabbage borer, cabbage aphid, leafminer, thrips, jj., haholo-holo khahlanong le batho ba baholo ba likokoanyana tse senyang lijalo tsa Lepidoptera, li sebetsa hantle haholo.
(2) Chlorfenapyr e na le chefo ea mala le litlamorao tsa ho bolaea likokoanyana. E na le bokhoni bo matla ba ho kenella holim'a makhasi, e na le phello e itseng ea tsamaiso, 'me e na le litšobotsi tsa mefuta e mengata ea ho bolaea likokoanyana, phello e phahameng ea taolo, phello e tšoarellang nako e telele le polokeho. Lebelo la ho bolaea likokoanyana le potlakile, ho kenella ho matla, 'me chefo e bolaeang likokoanyana e batla e phethahetse. (Likokonyana li ka bolaoa nakong ea hora e le 'ngoe kamora ho fafatsa, 'me katleho ea taolo ea letsatsi e ka fihla ho feta 85%).
(3) Chlorfenapyr e na le phello e matla ea taolo khahlanong le likokoanyana tse hanyetsanang, haholo-holo bakeng sa likokoanyana tse senyang lijalo le likokoanyana tse hanyetsanang le chefo e bolaeang likokoanyana tse kang organophosphorus, carbamate, le pyrethroids.
2. Ho kopanya chlorfenapyr
Leha chlorfenapyr e na le mefuta e mengata ea meriana e bolaeang likokoanyana, phello le eona e ntle, 'me khanyetso ea hona joale e tlase haholo. Leha ho le joalo, mofuta ofe kapa ofe oa moemeli, haeba o sebelisoa o le mong nako e telele, ka sebele o tla ba le mathata a khanyetso mohatong oa morao.
Ka hona, ha ho fafatswa ka sebele, chlorfenapyr e lokela ho kopanngoa le meriana e meng ho fokotsa tlhahiso ea ho hanyetsa meriana le ho ntlafatsa phello ea taolo.
(1) Motsoako oachlorfenapyr + emamectin
Kamora ho kopanya chlorfenapyr le emamectin, e na le mefuta e mengata ea meriana e bolaeang likokoanyana, 'me e ka laola li-thrips, likokoanyana tse nkhang hampe, li-flea beetle, li-red spider, li-heartworm, li-poone borer, li-cauliflower tsa k'habeche le likokoanyana tse ling merohong, masimong, lifateng tsa litholoana le lijalong tse ling.
Ho feta moo, kamora ho kopanya chlorfenapyr le emamectin, nako e telele ea moriana e ba telele, e leng se thusang ho fokotsa khafetsa ea ho sebelisa moriana le ho fokotsa litšenyehelo tsa ts'ebeliso ea balemi.
Nako e ntle ka ho fetisisa ea ho sebelisa: mohatong oa 1-3 oa ho sebelisa likokoanyana, ha tšenyo ea likokoanyana tšimong e ka ba 3%, 'me mocheso o laoloa ka likhato tse ka bang 20-30, phello ea ho sebelisa e molemo ka ho fetisisa.
(2) chlorfenapyr +indoxacarb e kopantsoe le indoxacarb
Kamora ho kopanya chlorfenapyr le indoxacarb, e ke ke ea bolaea likokoanyana kapele feela (likokonyana li tla khaotsa ho ja hang ka mor'a ho kopana le chefo e bolaeang likokoanyana, 'me likokoanyana li tla shoa matsatsing a 3-4), empa hape e boloka katleho ea eona nako e telele, e leng se loketseng lijalo haholoanyane. Polokeho.
Motswako wa chlorfenapyr le indoxacarb o ka sebediswa ho laola dikokonyana tse senyang lepidopteran, tse kang cotton bollworm, caterpillar ya dijalo tsa cruciferous, diamondback moth, beet armyworm, jj., haholoholo ho hanyetsa noctuid moth ho a makatsa.
Leha ho le jwalo, ha disebediswa tsena tse pedi di kopantswe, phello mahe ha e be ntle. Haeba o batla ho bolaya mahe le batho ba baholo, o ka sebedisa lufenuron mmoho.
Nako e ntle ka ho fetisisa ea ts'ebeliso: mekhahlelong e bohareng le ea morao ea kholo ea lijalo, ha likokoanyana li se li tsofetse, kapa ha meloko ea 2, 3, le 4 ea likokoanyana e tsoakane, phello ea moriana e ntle.
(3)chlorfenapyr + abamectin motsoako
Abamectin le chlorfenapyr li kopantsoe ka phello e totobetseng ea tšebelisano-'moho, 'me li sebetsa hantle khahlanong le li-thrips tse hanyetsanang haholo, liboko, beet armyworm, leek Kaofela li na le litlamorao tse ntle tsa taolo.
Nako e ntle ea ho e sebelisa: mekhahlelong e bohareng le ea morao ea kholo ea lijalo, ha mocheso o le tlase motšehare, phello e ba betere. (Ha mocheso o le tlase ho likhato tse 22, ts'ebetso ea ho bolaea likokoanyana ea abamectin e phahame).
(4) Tšebeliso e tsoakiloeng ea chlorfenapyr + tse lingchefo e bolaeang likokoanyana
Ho phaella moo, chlorfenapyr e ka boela ea kopanngoa le thiamethoxam, bifenthrin, tebufenozide, jj. ho laola li-thrip, li-moth tsa diamondback le likokoanyana tse ling.
Ha ho bapisoa le meriana e meng: chlorfenapyr e sebelisoa haholo ho laola likokoanyana tse senyang lijalo tsa lepidopteran, empa ntle le chlorfenapyr, ho na le meriana e meng e 'meli e nang le litlamorao tse ntle tsa taolo holim'a likokoanyana tse senyang lijalo tsa lepidopteran, e leng lufenuron le indene Wei.
Joale, phapang ke efe pakeng tsa meriana ena e meraro? Re lokela ho khetha moriana o nepahetseng joang?
Baemeli bana ba bararo ba na le melemo le mathata a bona. Litšebelisong tse sebetsang, re ka khetha moemeli ea loketseng ho latela boemo ba sebele.
