I lenei vaitau o tausaga taʻitasi, o le tele o faʻamaʻi faʻamaʻi e oso mai ('au'au, Spodoptera littoralis, Spodoptera litura, Spodoptera frugiperda, ma isi), e mafua ai le faʻaleagaina tele o mea totō.I le avea ai o se vailaʻau faʻamaʻi faʻamaʻi lautele, o le chlorfenapyr e iai sona aafiaga lelei i luga o nei meaola faalafua.
1. Uiga o le chlorfenapyr
(1) Chlorfenapyr o loʻo i ai le lautele o fusi o iniseti ma le tele o faʻaoga.E mafai ona fa'aoga e pulea ai le tele o ituaiga o fa'ama'i e pei ole Lepidoptera ma le Homoptera i fuala'au 'aina, fualaau 'aina, ma fuala'au fa'ato'aga, e pei ole mote taimane, anufe kapisi, anufe beet, ma le twill.O le tele o fa'ama'i fa'ama'i fuala'au e pei o le noctuid moth, cabbage borer, cabbage aphid, leafminer, thrips, etc., aemaise lava i tagata matutua o le Lepidoptera pests, e matua aoga lava.
(2) O le Chlorfenapyr o lo'o i ai le 'ona o le manava ma fa'afeso'ota'i a'afiaga o fa'ama'i fa'ama'i.E malosi le fa'aogaina i luga o lau laulaau, ei ai sona aafiaga fa'apitoa, ma ei ai uiga o le lautele o alaleo insecticidal, maualuga le pulea, aafiaga umi ma le saogalemu.O le saosaoa o le iniseti e vave, o le faʻaogaina e malosi, ma o le iniseti e fai si maeʻaeʻa.(E mafai ona faʻaumatia faʻamaʻi i totonu ole 1 le itula pe a uma le faʻafefe, ma o le lelei o le puleaina o le aso e mafai ona oʻo atu i le 85%).
(3) O le Chlorfenapyr e iai sona aafiaga maualuga e tetee atu ai i faʻamaʻi faʻamaʻi faʻamaʻi, aemaise lava mo faʻamaʻi faʻamaʻi ma mite e mafai ona tetee atu i vailaau faʻasaina e pei ole organophosphorus, carbamate, ma pyrethroids.
2. Fa'afefiloi ole chlorfenapyr
E ui lava o le chlorfenapyr o loʻo i ai le lautele o vailaʻau iniseti, e lelei foi le aʻafiaga, ma o le tetee o loʻo i ai nei e laʻititi lava.Ae ui i lea, soʻo se ituaiga o soʻotaga, pe a faʻaaogaina na o ia mo se taimi umi, o le a mautinoa lava le i ai o faʻafitauli tetee i le taimi mulimuli ane.
O le mea lea, i le faʻapipiʻiina moni, e tatau ona faʻafefiloi le chlorfenapyr ma isi vailaʻau e faʻagesegese ai le faʻatupuina o vailaʻau faʻasaina ma faʻaleleia le aʻafiaga.
(1) Fa'apotopotoga ochlorfenapyr + emamectin
A maeʻa le tuʻufaʻatasia o le chlorfenapyr ma le emamectin, o loʻo i ai le tele o faʻamaʻi iniseti, ma e mafai ona pulea le thrips, manogi leaga, flea beetles, apogaleveleve mumu, heartworms, saga, caterpillars kapisi ma isi faʻamaʻi i luga o fualaau faisua, fanua, fualaau aina ma isi mea totō. .
E le gata i lea, a maeʻa ona faʻafefiloi le chlorfenapyr ma le emamectin, o le taimi umi o le vailaʻau e umi, lea e aoga e faʻaitiitia ai le tele o le faʻaaogaina o vailaʻau ma faʻaitiitia le tau o le faʻaaogaina o faifaatoaga.
Ole taimi sili ole talosaga: ile 1-3 instar stage o faʻamaʻi, pe a faʻaleagaina le faʻamaʻi ile fanua e tusa ma le 3%, ma o le vevela e pulea ile 20-30 tikeri, o le aʻafiaga o le faʻaoga e sili ona lelei.
(2) chlorfenapyr +indoxacarb fefiloi ma indoxacarb
A maeʻa le faʻafefiloi o le chlorfenapyr ma le indoxacarb, e le gata e mafai ona vave faʻaumatia faʻamaʻi (o faʻamaʻi faʻamaʻi o le a taofi le 'ai vave pe a uma ona faʻafesoʻotaʻi le vailaau faʻamaʻi, ma o le a mate faʻamaʻi i totonu o le 3-4 aso), ae faʻatumauina foi le aoga mo se taimi umi, o le e sili atu foi ona talafeagai mo fua o faatoaga.Saogalemu.
O le faʻafefiloi o le chlorfenapyr ma le indoxacarb e mafai ona faʻaaogaina e pulea ai faʻamaʻi faʻamaʻi lepidopteran, e pei o le cotton bollworm, caterpillar caterpillar of cruciferous crops, moth diamondback, beet armyworm, ma isi, aemaise lava le tetee atu i moth noctuid e ofoofogia.
Ae peitaʻi, a faʻafefiloi nei vailaʻau e lua, o le aʻafiaga i fuamoa e le lelei.Afai e te manaʻo e tape uma fuamoa ma tagata matutua, e mafai ona e faʻaogaina faʻatasi le lufenuron.
Ole taimi sili ole fa'aoga: ile ogatotonu ma le tuai o la'asaga o le tuputupu a'e o fuala'au, pe a matutua le fa'ama'i, po'o le taimi e fa'afefiloi ai le 2nd, 3rd, ma le 4 o augatupulaga o fa'ama'i, e lelei le a'afiaga o vaila'au.
(3)chlorfenapyr + abamectin faʻapipiʻi
O le Abamectin ma le chlorfenapyr o loʻo tuʻufaʻatasia ma le manino o le synergistic aʻafiaga, ma e aoga tele e faʻasaga i thrips, anufe, beet armyworm, leek E iai uma aʻafiaga lelei.
Le taimi sili e faʻaaoga ai: i le ogatotonu ma le tuai o laʻasaga o le tuputupu ae o fualaʻau, pe a maualalo le vevela i le aso, e sili atu le aʻafiaga.(Pe a maualalo le vevela nai lo le 22 tikeri, o le gaioiga faʻamaʻi o le abamectin e maualuga atu).
(4) Fa'aaogā fa'afefiloi ole chlorfenapyr + isivailaau fa'ama'i
E le gata i lea, e mafai foi ona faʻafefiloi le chlorfenapyr ma le thiamethoxam, bifenthrin, tebufenozide, ma isi mea e pulea ai thrips, moths diamondback ma isi faʻamaʻi.
Pe a faʻatusatusa i isi vailaʻau: chlorfenapyr e masani ona faʻaaogaina e pulea ai faʻamaʻi faʻamaʻi lepidopteran, ae i le faʻaopoopoga i le chlorfenapyr, e lua isi vailaʻau e iai foʻi aʻafiaga lelei ile faʻamaʻi lepidopteran, e taʻua o le lufenuron ma indene Wei.
O lea la, o le a le eseesega i le va o nei vailaʻau e tolu?E tatau faapefea ona tatou filifilia le vailaau sa'o?
O nei sui e tolu e iai a latou lava lelei ma mea le lelei.I faʻatinoga faʻatinoga, e mafai ona tatou filifilia le sui talafeagai e tusa ai ma le tulaga moni.
