A cikin wannan kakar na kowace shekara, adadin kwari masu yawa suna fashewa (bug soja, Spodoptera littoralis, Spodoptera litura, Spodoptera frugiperda, da dai sauransu), yana haifar da mummunar lalacewa ga amfanin gona.A matsayin wakili mai faɗin bakan kwari, chlorfenapyr yana da tasiri mai kyau akan waɗannan kwari.
1. Halayen chlorfenapyr
(1) Chlorfenapyr yana da nau'ikan maganin kashe kwari da aikace-aikace iri-iri.Ana iya amfani da shi don sarrafa nau'ikan kwari iri-iri kamar Lepidoptera da Homoptera akan kayan lambu, bishiyoyin 'ya'yan itace, da amfanin gona na gona, kamar su asu mai lu'u-lu'u, tsutsawar kabeji, tsutsawar gwoza, da twill.Yawancin kwari na kayan lambu irin su noctuid moth, kabeji borer, kabeji aphid, leafminer, thrips, da dai sauransu, musamman a kan manya na Lepidoptera kwari, suna da tasiri sosai.
(2) Chlorfenapyr yana da guba na ciki da kuma tasirin kashe kwari akan kwari.Yana da karfi penetrability a kan leaf surface, yana da wani tsarin sakamako, kuma yana da halaye na m kwari bakan, high iko sakamako, dogon m sakamako da aminci.Gudun maganin kwari yana da sauri, shigarsa yana da ƙarfi, kuma maganin kwari yana da ɗanɗano sosai.(Za a iya kashe kwari a cikin sa'a 1 bayan fesa, kuma ingancin sarrafa rana zai iya kaiwa fiye da 85%).
(3) Chlorfenapyr yana da babban tasiri mai tasiri akan kwari masu juriya, musamman ga kwari da mites waɗanda ke da tsayayya ga magungunan kashe qwari irin su organophosphorus, carbamate, da pyrethroids.
2. Cakuda na chlorfenapyr
Ko da yake chlorfenapyr yana da nau'in maganin kashe kwari, tasirin yana da kyau, kuma juriya na yanzu yana da ƙananan ƙananan.Duk da haka, kowane irin wakili, idan aka yi amfani da shi kadai na dogon lokaci, tabbas zai sami matsalolin juriya a mataki na gaba.
Sabili da haka, a cikin ainihin spraying, chlorfenapyr ya kamata a haɗe shi da sauran kwayoyi don rage jinkirin tsararrun magungunan ƙwayoyi da inganta tasirin sarrafawa.
(1) Haɗin kaichlorfenapyr + emamectin
Bayan hadewar chlorfenapyr da emamectin, yana da nau'ikan maganin kashe kwari, kuma yana iya sarrafa thrips, kwari masu wari, ƙwaro ƙuma, gizo-gizo ja, tsutsotsin zuciya, ƙwararrun masara, caterpillars na kabeji da sauran kwari akan kayan lambu, gonaki, itatuwan 'ya'yan itace da sauran amfanin gona. .
Bugu da ƙari, bayan haxa chlorfenapyr da emamectin, tsawon lokaci na maganin yana da tsawo, wanda ke da amfani don rage yawan amfani da magungunan da kuma rage farashin amfani da manoma.
Mafi kyawun lokacin aikace-aikacen: a cikin 1-3 instar mataki na kwari, lokacin da lalacewar kwari a cikin filin ya kusan 3%, kuma ana sarrafa zafin jiki a kusan digiri 20-30, tasirin aikace-aikacen shine mafi kyau.
(2) chlorfenapyr +indoxacarb hade da indoxacarb
Bayan haxa chlorfenapyr da indoxacarb, ba kawai zai iya kashe kwari da sauri ba (kwarin za su daina cin abinci nan da nan bayan tuntuɓar magungunan kashe qwari, kuma kwari za su mutu a cikin kwanaki 3-4), amma kuma suna kula da inganci na dogon lokaci, wanda shine kuma ya fi dacewa da amfanin gona.Tsaro.
Cakuda chlorfenapyr da indoxacarb za a iya amfani da su don sarrafa lepidopteran kwari, kamar auduga bollworm, kabeji caterpillar cruciferous amfanin gona, diamondback asu, gwoza Armyworm, da dai sauransu, musamman juriya ga noctuid asu ne na ban mamaki.
Duk da haka, lokacin da waɗannan wakilai biyu suka haɗu, tasirin ƙwai ba shi da kyau.Idan kuna son kashe ƙwai da manya, zaku iya amfani da lufenuron tare.
Mafi kyawun lokacin aikace-aikacen: a cikin tsakiyar da ƙarshen matakan girma na amfanin gona, lokacin da kwari suka tsufa, ko lokacin da 2nd, 3rd, da 4th ƙarni na kwari suka haɗu, tasirin magani yana da kyau.
(3)chlorfenapyr + abamectin fili
Abamectin da chlorfenapyr suna haɗuwa tare da tasirin synergistic a bayyane, kuma yana da tasiri a kan juriya mai ƙarfi, caterpillars, gwoza Armyworm, leek Duk suna da tasirin sarrafawa mai kyau.
Mafi kyawun lokaci don amfani da shi: a cikin tsakiyar da ƙarshen matakan girma na amfanin gona, lokacin da yawan zafin jiki ya ragu a lokacin rana, tasirin ya fi kyau.(Lokacin da zafin jiki ya yi ƙasa da digiri 22, aikin kwari na abamectin ya fi girma).
(4) Mixed amfani da chlorfenapyr + wasumagungunan kashe qwari
Bugu da ƙari, chlorfenapyr kuma ana iya haɗa shi da thiamethoxam, bifenthrin, tebufenozide, da dai sauransu don sarrafa thrips, asu diamondback da sauran kwari.
Idan aka kwatanta da sauran magungunan: chlorfenapyr ana amfani da shi ne don sarrafa kwari na lepidopteran, amma ban da chlorfenapyr, akwai wasu magunguna guda biyu waɗanda kuma suna da tasiri mai kyau akan ƙwayoyin lepidopteran, wato lufenuron da indene Wei.
To, menene bambancin waɗannan magunguna guda uku?Ta yaya za mu zabi maganin da ya dace?
Wadannan wakilai guda uku suna da nasu amfani da rashin amfani.A cikin aikace-aikace masu amfani, za mu iya zaɓar wakili mai dacewa bisa ga ainihin halin da ake ciki.
