Isibulala-zinambuzane sekhwalithi ephezulu i-Dinotefuran 98% Tc CAS 165252-70-0 ngentengo ephansi
Izakhiwo zomzimba nezamakhemikhali
I-Dinotefuran uhlobo lwesibulala-zinambuzane se-neonicotinoid, ngokuvamile esinezinzuzo zokusebenza kahle kakhulu, ubuthi obuphansi, ububanzi bezinambuzane ezibulala izinambuzane kanye nomphumela ohlala isikhathi eside.
1. Umsebenzi omkhulu wokubulala izinambuzane
I-Dinotefuran inezici zokuthintana okunamandla, ubuthi esiswini, kanye nokumuncwa kwezimpande, umphumela osheshayo ophezulu, isikhathi eside samasonto angu-4-8 (ubude bezinsuku ezingu-43), kanye nobubanzi bokubulala izinambuzane. Inomthelela omuhle kakhulu wokulawula izinambuzane ezilumayo nezimuncayo, futhi ikhombisa umsebenzi ophezulu wokubulala izinambuzane ngesilinganiso esiphansi kakhulu.
2. Ububanzi bezinhlobo zezibulala-zinambuzane
I-Dinotefuran isetshenziswa kakhulu ukulawula ama-aphid, i-leafhopper, i-planthopper kanye ne-thistle kukolweni, ilayisi, ukotini, imifino, izihlahla zezithelo, ugwayi kanye nezinye izitshalo. Ihhashi, i-whitefly kanye nezinhlobo zazo ezimelana nayo zisebenza kahle kakhulu ngokumelene nezinambuzane ze-Coleoptera, i-diptera, i-lepidoptera kanye ne-homoptera, kanye nokulwa nama-cockroaches, izintuthwane, izimpukane zasendlini, njll. Impilo izinambuzane zilawula ngempumelelo.
3. Inomphumela wokungena okuphezulu
I-Dinotefuran inomphumela ophezulu we-osmotic. Isetshenziswa ekutshalweni kwemifino futhi ifuduka kahle isuka ebusweni beqabunga iye eqabungeni ngaphakathi. Ama-granules enhlabathini eyomile (inhlabathi Ngaphansi kwesimo somswakama wenhlabathi ofika ku-5%), isengadlala umphumela ozinzile.
4. Akukho ukumelana
I-Dinotefuran ingeyesizukulwane sesithathu semithi yokubulala izinambuzane ye-neonicotinoid, kanti ezinye izinto azinawo amandla okumelana nayo yonke into, kanti i-dinotefuran ayinawo amandla okumelana nemithi ye-nicotine.
Izinambuzane ezimelana nezinambuzane zinomphumela ongcono wokulawula.
5. isikhathi eside
I-Dinotefuran inesikhathi eside sokubulala izinambuzane esihlala isikhathi eside, esingafinyelela amasonto angu-4-8, futhi ukulawulwa kwezinambuzane kuphelele, ngoba isikhathi sokulawula side.
Kunzima ukuthi izinambuzane ziphinde zivele ngemva kokulawula ukufafaza.
6. Umphumela osheshayo
Ngemva kokusetshenziswa kwe-dinotefuran, ingamuncwa ngokushesha yizitshalo, futhi ingasakazeka kabanzi ezimbalini, emaqabunga, ezithelweni, eziqwini nasezimpandeni zezitshalo.
Emzimbeni, uma i-ejenti ifuthwa ngaphambili nangemuva kwe-blade, ingafeza ngempela umphumela wokulwa nokufa nokulwa nokufa.
I-spectrum yokubulala izinambuzane
Izinambuzane zelayisi
Ukusebenza kahle okuphezulu: I-planthopper ensundu, i-planthopper emhlophe ngemuva, i-planthopper empunga, i-black-tailed leafhopper, i-rice spider, i-Rafter bug elephant, i-star bug elephant, i-rice green bug elephant, i-red palpate bug bug, i-rice mixed worm, i-rice tube water borer.
Isebenza kahle: I-Borer, ilayisi I-Locust.
Izinambuzane zemifino nezithelo
Ukusebenza kahle okuphezulu: ama-aphid, i-whitefly, i-scale, i-Aphidococcus, i-Vermilion bug, i-peach small food worm, i-orange moth, i-tea moth, i-yellow stripe beetle, i-bean fly.
Isebenza kahle: I-Ceratococcus aureus, i-Diamifolia nigra, ama-thrips aphuzi e-Tea, ama-thrips e-smoke, ama-thrips aphuzi, ama-thrips aphuzi e-citrus, i-bean pod gall midge, i-tomato leaf miner fly.
Indlela yokusebenzisa
1. Izitshalo zemifino (kusetshenziswa ama-granule angu-l% kanye nama-granule angu-20% ancibilika emanzini): ama-granule angu-l% angaxutshwa nomhlabathi onemigodi yenhlabathi ngesikhathi sokufakelwa kwezithelo nemifino kanye nemifino enamaqabunga, noma axutshwe nomhlabathi osemathinini okutshala ngesandla ngesikhathi sokutshala. Lokhu kungalawula izinambuzane ezidla ezinye ngesikhathi sokufakelwa kanye nezinambuzane ezindizayo ngaphambi kokufakelwa. Ngaphezu kwalokho, ngoba umuthi unomoya omuhle we-endothermic, ungamuncwa ngokushesha yizitshalo ngemva kokwelashwa, futhi ungagcina ukusebenza kahle amasonto angu-4 kuya kwangu-6.
Ama-granule ancibilika emanzini angu-20% angasetshenziswa njengezinto zokwelapha izimpande namaqabunga ukulawula izinambuzane. Izindlela ezimbili zokwelapha, “ukwelashwa kokufakelwa kwamanzi” kanye “nokwelashwa kokufakelwa komhlabathi ngesikhathi sokukhula”, ziyahlolwa. Ama-granule ashiwo ngenhla angahlanganiswa nama-granule ancibilika emanzini ukuze asetshenziswe kusukela ekuqaleni kokukhula kwesitshalo kuze kube sekuvunweni.
2, izihlahla zezithelo (20% ama-granule ancibilika emanzini): Ama-granule ancibilika emanzini asetshenziswa njengezinto zokwelapha isiqu namaqabunga lapho kuvela izinambuzane, ezingalawula ngempumelelo ama-aphid, izinambuzane ezimunca i-red scale, izinambuzane zokudla, ama-golden grain moth kanye nezinye izinambuzane ze-lepidoptera. Ngaphezu kwalokho, futhi inomphumela omuhle wokubulala izinambuzane ezizinambuzaneni, kanye nokuvimbela okuphezulu komphumela wokumunca. Umthamo onconywayo, akukho monakalo, ukuhlolwa komthamo ophindwe kabili, futhi kuhle kakhulu ezitshalweni. Njengoba isetshenziswa ezitshalweni zemifino, inomphumela wokungena nokufuduka kusuka ebusweni beqabunga kuya eqabungeni ngaphakathi. Ngesikhathi esifanayo, futhi iyizitha zemvelo ezibaluleke kakhulu zezihlahla zezithelo.
3, ilayisi (2% ama-granule ebhokisi lezithombo, ama-granule angu-l%, i-0.5% DL powder): Uma isetshenziswa elayisini, i-DL powder kanye nama-granule kungasetshenziswa ngesilinganiso esingu-30kg/hm2 (isithako esisebenzayo esingu-10-20g/hm2), esingalawula ngempumelelo izibungu zezitshalo, i-black-tailed leafhopper, i-rice negative mud worm kanye nezinye izinambuzane. Ikakhulukazi ezilokazaneni zezinambuzane, umehluko womphumela phakathi kwezinhlobo mkhulu kakhulu. Ngemva kokusebenzisa ibhokisi lezithombo, lingalawula ngempumelelo i-planthopper, i-black-tailed leafhopper, i-rice bug kanye ne-rice tube water borer ngemva kokufakelwa. Umuthi unomthelela omude ezilokazaneni ezihlosiwe, futhi usengalawula ngempumelelo inani lezinambuzane ngemva kwezinsuku ezingu-45. Njengamanje, kwenziwa izivivinyo ezengeziwe ezinambuzaneni ezifana ne-Borer, i-rice borer kanye ne-rice black bug.
Izindlela zokuqapha zokusebenzisa i-Dinofuran:
1. Sebenzisa isikhathi
Ngesikhathi sokuqhakaza kwezitshalo, isikhathi sokuqhakaza kwelayisi, ukusetshenziswa kwe-furosemide akuvunyelwe ngoba i-furosemide inobuthi ezintweni eziphilayo zasemanzini njengezinyosi kanye nezimfanzi.
2. Ububanzi bokusetshenziswa
I-Furoxamine inobuthi kuma-silkworm, izinyosi, ama-shrimp kanye nama-crab, ngakho-ke akuvunyelwe ukuyisebenzisa ekulimeni i-sericulture, engadini yama-mulberry, ama-shrimp kanye nama-crab afaka izidleke emasimini elayisi. Ngaphezu kwalokho, i-dinotefuran ibangela ukungcola kwamanzi angaphansi komhlaba kalula, ngakho-ke kufanele isetshenziswe ngokuqapha ezindaweni ezinomhlabathi omuhle noma amazinga angaphansi komhlaba angajulile.
