Muri iki gihembwe cya buri mwaka, udukoko twinshi (army bug, Spodoptera littoralis, Spodoptera litura, Spodoptera frugiperda, nibindi), bigatera kwangirika gukomeye ku bihingwa. Nk'umuti wica udukoko mu buryo bwagutse, chlorfenapyr igira ingaruka nziza ku dukoko.
1. Ibiranga chlorfenapyr
(1) Chlorfenapyr ifite ubwoko bwinshi bw'imiti yica udukoko ndetse n'uburyo bwinshi bwo kuyikoresha. Ishobora gukoreshwa mu kurwanya ubwoko bwinshi bw'udukoko nka Lepidoptera na Homoptera ku mboga, ibiti by'imbuto, n'ibihingwa byo mu murima, nka diamondback moth, cabbage worm, beet armyworm, na twill. Udukoko twinshi tw'imboga nka noctuid moth, cabbage borer, cabbage aphid, leafminer, thrips, n'ibindi, cyane cyane ku dukoko twa Lepidoptera dukuze, ngira akamaro cyane.
(2) Chlorfenapyr igira uburozi mu gifu kandi yica udukoko. Ifite ubushobozi bwo kwinjira cyane ku buso bw'amababi, ifite ingaruka zimwe na zimwe ku mubiri, kandi ifite imiterere yo kwica udukoko mu buryo bwagutse, ifite ingaruka zo kugenzura cyane, ifite ingaruka zirambye kandi ifite umutekano. Umuvuduko wo kwica udukoko ni wihuta, kwinjira ni mwinshi, kandi umuti wica udukoko ni mwiza cyane. (Udukoko dushobora kwicwa mu isaha imwe nyuma yo gutera imiti, kandi ubushobozi bwo kugenzura umunsi bushobora kugera kuri 85%).
(3) Chlorfenapyr ifite ingaruka zikomeye ku kurwanya udukoko twihanganira, cyane cyane ku dukoko n'udukoko twihanganira imiti yica udukoko nka organophosphorus, carbamate, na pyrethroids.
2. Kuvanga chlorfenapyr
Nubwo chlorfenapyr ifite ubwoko bwinshi bw'imiti yica udukoko, ingaruka zayo ni nziza, kandi ubushobozi bwayo bwo kurwanya udukoko buri hasi cyane. Ariko, ubwoko ubwo aribwo bwose bw'imiti, iyo bukoreshejwe bwonyine igihe kirekire, nta gushidikanya ko buzagira ibibazo byo kurwanya udukoko mu gihe cya nyuma.
Bityo rero, mu gutera umuti, chlorfenapyr igomba kuvangwa n'indi miti kugira ngo igabanye umuvuduko wo kudakira imiti no kunoza ingaruka zo kuyigenzura.
(1) Urusobe rw'ibicechlorfenapyr + emamectin
Nyuma yo kuvanga chlorfenapyr na emamectin, ifite ubwoko bwinshi bw'imiti yica udukoko, kandi ishobora kurwanya udukoko twa thrips, udukoko tunuka, udukoko tw'inyenzi, udusimba dutukura, inzoka zo mu mutima, udukoko two mu bigori, udukoko tw'amashu n'utundi dukoko ku mboga, mu mirima, ku biti by'imbuto n'ibindi bihingwa.
Byongeye kandi, nyuma yo kuvanga chlorfenapyr na emamectin, igihe kirekire cy'umuti kiba kirekire, ibyo bikaba ari ingirakamaro mu kugabanya inshuro zo gukoresha umuti no kugabanya ikiguzi cyo kuwukoresha cy'abahinzi.
Igihe cyiza cyo gukoresha: mu cyiciro cya 1-3 cy'udukoko, iyo ibyangiritse mu murima ari hafi 3%, kandi ubushyuhe bukagenzurwa kuri dogere 20-30, ingaruka zo gukoresha ni nziza cyane.
(2) chlorfenapyr +indoxacarb ivanze na indoxacarb
Nyuma yo kuvanga chlorfenapyr na indoxacarb, ntabwo ishobora kwica udukoko vuba gusa (udukoko duhita duhagarika kurya ako kanya nyuma yo gukora ku muti wica udukoko, kandi udukoko tuzapfa mu minsi 3-4), ahubwo ikanakomeza kugira akamaro igihe kirekire, kandi ni byo bibereye imyaka. Umutekano.
Uruvange rwa chlorfenapyr na indoxacarb rushobora gukoreshwa mu kurwanya udukoko twa lepidopteran, nk'udukoko tw'ipamba, caterpillar y'ibihingwa bya cruciferous, diamondback moth, beet armyworm, n'ibindi, cyane cyane ko kurwanya noctuid moth ari ibintu bitangaje.
Ariko, iyo ibi bintu bibiri bivanze, ingaruka ku magi ntabwo ziba nziza. Niba ushaka kwica amagi yombi n'amakuru, ushobora gukoresha lufenuron hamwe.
Igihe cyiza cyo gukoresha: hagati n'igihe cyo gukura kw'ibihingwa, iyo udukoko tumaze gukura, cyangwa iyo udukoko two mu gisekuru cya 2, icya 3, n'icya 4 bivanze, ingaruka z'umuti ziba nziza.
Abamectin na chlorfenapyr bivanze n'ingaruka zigaragara z'ubufatanye, kandi bigira ingaruka nziza ku bikoko birwanya udukoko twitwa thrips, caterpillars, beet armyworm, leek. Byose bigira ingaruka nziza zo kurwanya.
Igihe cyiza cyo kuyikoresha: hagati n'igihe cyo kurangira kw'ibihingwa, iyo ubushyuhe buri hasi ku manywa, ingaruka ziba nziza kurushaho. (Iyo ubushyuhe buri munsi ya dogere 22, imikorere y'udukoko twa abamectin iba iri hejuru).
(4) Gukoresha chlorfenapyr mu buryo buvanze n'ibindiimiti yica udukoko
Byongeye kandi, chlorfenapyr ishobora kandi kuvangwa na thiamethoxam, bifenthrin, tebufenozide, nibindi kugira ngo irwanye udukoko twa thrips, diamondback moths n'utundi dukoko.
Ugereranyije n'indi miti: chlorfenapyr ikoreshwa cyane cyane mu kurwanya udukoko twa lepidopteran, ariko uretse chlorfenapyr, hari indi miti ibiri ifite ingaruka nziza zo kurwanya udukoko twa lepidopteran, ari yo lufenuron na indene Wei.
None se, itandukaniro riri hagati y'iyi miti itatu ni irihe? Ni gute twahitamo umuti ukwiye?
Aba bakozi batatu bafite ibyiza n'ibibi byabo. Mu buryo bufatika, dushobora guhitamo umukozi ukwiye bitewe n'uko ibintu bimeze.
