Kule sizini yonyaka ngamnye, kuqhambuka inani elikhulu lezinambuzane (army bug, Spodoptera littoralis, Spodoptera litura, Spodoptera frugiperda, njl.njl.), nto leyo ebangela umonakalo omkhulu kwizityalo. Njenge-arhente yokubulala izinambuzane ebanzi, i-chlorfenapyr inefuthe elihle lokulawula ezi zinambuzane.
1. Iimpawu ze-chlorfenapyr
(1) I-Chlorfenapyr ineentlobo ngeentlobo zezibulali-zinambuzane kunye neendlela ezahlukeneyo zokusetyenziswa. Ingasetyenziselwa ukulawula iintlobo ezininzi zezinambuzane ezifana neLepidoptera kunye neHomoptera kwimifuno, imithi yeziqhamo, kunye nezityalo zasemasimini, ezifana ne-diamondback moth, i-cabbage worm, i-beet armyworm, kunye ne-twill. Izinambuzane ezininzi zemifuno ezifana ne-noctuid moth, i-cabbage borer, i-cabbage aphid, i-leafminer, i-thrips, njl.njl., ingakumbi nxamnye nezinambuzane ezindala zeLepidoptera, zisebenza kakhulu.
(2) I-Chlorfenapyr inetyhefu esiswini kwaye ibulala izinambuzane ezinobungozi. Iyakwazi ukungena kakuhle kumphezulu wegqabi, inefuthe elithile kwinkqubo, kwaye ineempawu zokubulala izinambuzane ezibanzi, ifuthe eliphezulu lokulawula, ifuthe elihlala ixesha elide kunye nokhuseleko. Isantya sokubulala izinambuzane siyakhawuleza, ukungena kunamandla, kwaye isibulali-zinambuzane siphelele. (Izinambuzane zinokubulawa kwiyure e-1 emva kokutshiza, kwaye ukusebenza kakuhle kokulawula kosuku kunokufikelela ngaphezulu kwama-85%).
(3) I-Chlorfenapyr inefuthe eliphezulu lokulawula izinambuzane ezinganyangekiyo, ingakumbi kwizinambuzane kunye neencukuthu ezinganyangekiyo kwizinambuzane ezifana ne-organophosphorus, i-carbamate, kunye ne-pyrethroids.
2. Ukuxuba i-chlorfenapyr
Nangona i-chlorfenapyr ineentlobo ezahlukeneyo zezibulali-zinambuzane, isiphumo sayo silungile, kwaye ukumelana kwangoku kuphantsi kakhulu. Nangona kunjalo, naluphi na uhlobo lwearhente, ukuba lusetyenziswa lodwa ixesha elide, ngokuqinisekileyo luya kuba neengxaki zokuxhathisa kwinqanaba lokugqibela.
Ngoko ke, xa kutshizwa, i-chlorfenapyr kufuneka ixutywe nezinye iziyobisi ukuze kuncitshiswe isantya sokuveliswa kokuxhathisa amayeza nokuphucula isiphumo solawulo.
(1) Ikhompawundi yei-chlorfenapyr + i-emamectin
Emva kokudityaniswa kwe-chlorfenapyr kunye ne-emamectin, ineentlobo ngeentlobo zee-insecticide, kwaye inokulawula ii-thrips, ii-stink bugs, ii-flea beetles, izigcawu ezibomvu, ii-heartworms, ii-corn borers, ii-capers zekhaphetshu kunye nezinye izinambuzane kwimifuno, emasimini, kwimithi yeziqhamo nakwezinye izityalo.
Ngaphezu koko, emva kokuxuba i-chlorfenapyr kunye ne-emamectin, ixesha elide leyeza lihlala lide, nto leyo eluncedo ekunciphiseni ukuphindaphindwa kokusetyenziswa kwamayeza kunye nokunciphisa iindleko zokusetyenziswa kwabalimi.
Ixesha elifanelekileyo lokufaka: kwisigaba se-1-3 seenkwenkwezi zezinambuzane, xa umonakalo wezinambuzane endle umalunga ne-3%, kwaye ubushushu bulawulwa malunga nama-20-30 degrees, isiphumo sokufaka singcono kakhulu.
(2) i-chlorfenapyr +i-indoxacarb exutywe ne-indoxacarb
Emva kokuxuba i-chlorfenapyr kunye ne-indoxacarb, ayinakubulala nje kuphela izinambuzane ngokukhawuleza (izinambuzane ziya kuyeka ukutya kwangoko emva kokudibana nesibulali-zinambuzane, kwaye izinambuzane ziya kufa kwiintsuku ezi-3-4), kodwa ikwagcina ukusebenza kwayo ixesha elide, nto leyo ikwafaneleka ngakumbi kwizityalo. Ukhuseleko.
Umxube we-chlorfenapyr kunye ne-indoxacarb ungasetyenziselwa ukulawula izinambuzane ze-lepidopteran, ezifana ne-cotton bollworm, ikhaphetshu i-cauliflower yezityalo ze-cruciferous, i-diamondback moth, i-beet armyworm, njl.njl., ingakumbi ukumelana ne-noctuid moth kuyamangalisa.
Nangona kunjalo, xa ezi zinto zimbini zixutyiwe, isiphumo asibi sihle kumaqanda. Ukuba ufuna ukubulala amaqanda kunye namadala, ungasebenzisa i-lufenuron kunye.
Ixesha elifanelekileyo lokusetyenziswa: kumanqanaba aphakathi nasekupheleni kokukhula kwesityalo, xa izinambuzane zindala, okanye xa izizukulwana zesibini, zesithathu, nezesine zezinambuzane zixutyiwe, isiphumo samayeza siba sihle.
(3)chlorfenapyr + abamectin ikhompawundi
I-Abamectin kunye ne-chlorfenapyr zidibene nefuthe elicacileyo lokusebenzisana, kwaye ziyasebenza ngokuchasene ne-thrips ezixhathisayo kakhulu, ii-caterpillars, i-beet armyworm, kunye ne-leek. Zonke zinemiphumo emihle yokulawula.
Elona xesha lilungileyo lokuyisebenzisa: kwisigaba esiphakathi nesokugqibela sokukhula kwesityalo, xa ubushushu buphantsi emini, isiphumo siba ngcono. (Xa ubushushu bungaphantsi kwama-22 degrees, umsebenzi wokubulala izinambuzane we-abamectin uphezulu).
(4) Ukusetyenziswa okuxutyiweyo kwe-chlorfenapyr kunye nezinye izintoizibulali-zinambuzane
Ukongeza, i-chlorfenapyr ingaxutywa ne-thiamethoxam, i-bifenthrin, i-tebufenozide, njl.njl. ukulawula ii-thrips, ii-diamondback moths kunye nezinye izinambuzane.
Xa kuthelekiswa nezinye iziyobisi: i-chlorfenapyr isetyenziswa kakhulu ukulawula izinambuzane ze-lepidopteran, kodwa ukongeza kwi-chlorfenapyr, kukho ezinye iziyobisi ezimbini ezinemiphumo emihle yokulawula izinambuzane ze-lepidopteran, ezizezi i-lufenuron kunye ne-indene Wei.
Ngoko ke, yintoni umahluko phakathi kwala mayeza mathathu? Sifanele sikhethe njani amayeza afanelekileyo?
Ezi arhente zintathu zinezibonelelo kunye neengxaki zazo. Kwiindlela ezisebenzayo, singakhetha iarhente efanelekileyo ngokwemeko yokwenyani.
