A matsayin maganin kashe kwari mai faɗi, chlorfenapyr yana da kyakkyawan tasirin sarrafawa akan waɗannan kwari.
1. Halayen chlorfenapyr
(1) Chlorfenapyr yana da nau'ikan maganin kwari iri-iri da kuma amfani da shi iri-iri. Ana iya amfani da shi don magance nau'ikan kwari iri-iri kamar Lepidoptera da Homoptera akan kayan lambu, bishiyoyin 'ya'yan itace, da amfanin gona na gona, kamar su diamondback moth, cabbageworm, beet armyworm, da twill. Kwari da yawa na kayan lambu kamar noctuid moth, cabbage borer, cabbage aphid, leafminer, thrips, da sauransu, musamman akan manya na Lepidoptera kwari, suna da tasiri sosai.

2. Haɗa chlorfenapyr
Duk da cewa chlorfenapyr yana da nau'ikan magungunan kashe kwari iri-iri, tasirinsa ma yana da kyau, kuma juriyar da ake da ita a yanzu ba ta da yawa. Duk da haka, duk wani nau'in maganin, idan aka yi amfani da shi shi kaɗai na dogon lokaci, tabbas zai sami matsalolin juriya a matakin ƙarshe.
Saboda haka, a cikin feshin magani na gaske, ya kamata a haɗa chlorfenapyr da wasu magunguna don rage ƙarfin juriyar magani da kuma inganta tasirin sarrafawa.
(1) Haɗaɗɗenchlorfenapyr + emamectin
Bayan haɗa chlorfenapyr da emamectin, yana da nau'ikan maganin kwari iri-iri, kuma yana iya sarrafa thrips, ƙwari masu wari, ƙwari masu ƙuma, gizo-gizo ja, tsutsotsi masu kama da zuciya, masu ɓuya daga masara, tsutsotsi na kabeji da sauran kwari a kan kayan lambu, gonaki, bishiyoyin 'ya'yan itace da sauran amfanin gona.
Bugu da ƙari, bayan haɗa chlorfenapyr da emamectin, tsawon lokacin maganin yana da tsawo, wanda hakan yana da amfani wajen rage yawan amfani da maganin da kuma rage farashin amfani da manoma.
Mafi kyawun lokacin amfani: a matakin farko na kwari 1-3, lokacin da lalacewar kwari a cikin filin ya kai kusan kashi 3%, kuma ana sarrafa zafin jiki a kusan digiri 20-30, tasirin amfani shine mafi kyau.
(2) chlorfenapyr +indoxacarb da aka haɗa da indoxacarb
Bayan an haɗa chlorfenapyr da indoxacarb, ba wai kawai zai iya kashe kwari da sauri ba (ƙwarin za su daina cin abinci nan da nan bayan sun taɓa maganin kwari, kuma kwari za su mutu cikin kwana 3-4), amma kuma za su ci gaba da amfani da shi na dogon lokaci, wanda kuma ya fi dacewa da amfanin gona. Tsaro.
Ana iya amfani da cakuda chlorfenapyr da indoxacarb don magance kwari na lepidopteran, kamar su bollworm na auduga, ƙwarƙwarar kabeji na amfanin gona na cruciferous, moth na diamondback, beet armyworm, da sauransu, musamman juriya ga moth na noctuid abin mamaki ne.
Duk da haka, idan aka haɗa waɗannan sinadarai guda biyu, tasirinsu ga ƙwai ba shi da kyau. Idan kana son kashe ƙwai da manya, za ka iya amfani da lufenuron tare.
Mafi kyawun lokacin amfani: a matakin tsakiya da ƙarshen girma na amfanin gona, lokacin da kwari suka tsufa, ko kuma lokacin da ƙarni na 2, 3, da 4 na kwari suka haɗu, tasirin maganin yana da kyau.
(3)chlorfenapyr + abamectin fili
Ana haɗa Abamectin da chlorfenapyr da wani sinadari mai kama da juna, kuma yana da tasiri a kan thrips, tsutsotsi, tsutsotsi na beet, da leek. Duk suna da kyakkyawan tasirin sarrafawa.
Mafi kyawun lokacin amfani da shi: a matakin tsakiya da ƙarshen girma na amfanin gona, lokacin da zafin jiki ya yi ƙasa da rana, tasirin ya fi kyau. (Lokacin da zafin ya yi ƙasa da digiri 22, aikin kashe kwari na abamectin yana ƙaruwa).
(4) Amfani da chlorfenapyr + wasumagungunan kashe kwari
Bugu da ƙari, ana iya haɗa chlorfenapyr da thiamethoxam, bifenthrin, tebufenozide, da sauransu don magance thrips, ƙwari diamondback da sauran kwari.
Idan aka kwatanta da sauran magunguna: galibi ana amfani da chlorfenapyr don magance kwari na lepidopteran, amma ban da chlorfenapyr, akwai wasu magunguna guda biyu waɗanda suma suna da kyakkyawan tasirin hana kwari na lepidopteran, wato lufenuron da indene Wei.
To, menene bambanci tsakanin waɗannan magunguna guda uku? Ta yaya ya kamata mu zaɓi maganin da ya dace?
Waɗannan wakilai uku suna da nasu fa'idodi da rashin amfani. A aikace-aikace, za mu iya zaɓar wakilin da ya dace bisa ga ainihin yanayin.
