Spinosad nziza cyane CAS 131929-60-7 hamwe no gutanga vuba

Ibisobanuro by'igicuruzwa

Spinosad ni uburozi buke, ikora neza cyane,Udukoko twa fungicide twinshiKandi yakoreshejwe hirya no hino ku isi mukurwanya udukoko dutandukanye, harimo Lepidoptera, Diptera, Thysanoptera, Coleoptera, Orthoptera na Hymenoptera, n'ibindi byinshi. Spinosad nayo ifatwa nk'umusaruro karemano, bityo yemerewe gukoreshwa mu buhinzi bw'umwimerere n'ibihugu byinshi.

Gukoresha Uburyo

1. Ku mbogakurwanya udukokobya diamondback moth, koresha 2.5% by'umuti utera umuti inshuro 1000-1500 kugira ngo utere umuti ku buryo bungana mu gihe cy'inkoko nto, cyangwa koresha 2.5% by'umuti utera umuti ku kigero cya 33-50ml kugeza kuri 20-50kg buri metero 667.².

2. Kugira ngo urwanye inzoka zo mu bwoko bwa beet armyworm, shyiramo 2.5% by'umuti wo mu bwoko bwa 50-100ml buri metero kare 667 mu ntangiriro z'inkoko, kandi ingaruka nziza ni nimugoroba.

3. Kugira ngo hirindwe kandi hagenzurwe udukoko twa thrips, buri metero kare 667, koresha 2.5% by'umuti utera amazi 33-50ml, cyangwa koresha 2.5% by'umuti utera amazi inshuro 1000-1500 z'amazi kugira ngo uteranye neza, wibanda ku bice bito nk'indabyo, imbuto nto, imitwe n'imitsi.

Ibitekerezo

1. Bishobora kuba uburozi ku mafi cyangwa ku bindi binyabuzima byo mu mazi, kandi umwanda w’amazi n’ibidendezi ugomba kwirindwa.

2. Bika umuti ahantu hakonje kandi humutse.

3. Igihe kiri hagati yo gutera ubwa nyuma no gusarura ni iminsi 7. Irinde guhura n'imvura mu masaha 24 nyuma yo gutera.

4. Itondere uburyo bwo kwirinda indwara. Iyo igeze mu maso, oza vuba n'amazi menshi. Iyo ikoze ku ruhu cyangwa ku myenda, oza n'amazi menshi cyangwa amazi y'isabune. Iyo ifashwe nabi, ntugatere kuruka wenyine, ntugahe ikintu icyo ari cyo cyose cyangwa ngo utere kuruka ku barwayi batasinziriye cyangwa bafite imitsi. Umurwayi agomba guhita yoherezwa kwa muganga kuvurwa.

Uburyo bwo gukora

Uburyo polycidin ikora ni bushya cyane kandi bwihariye, bitandukanye n’uturemangingo rusange twa macrolides, kandi imiterere yayo yihariye ya shimi niyo igena uburyo bwayo bwihariye bwo kwica udukoko. Polycidin ifite uburozi bwihuse bwo gukora no kwinjiza udukoko. Ifite ibimenyetso byihariye by’uburozi bw’imitsi. Uburyo ikora ni ugukangura sisitemu y’imitsi y’udukoko, kongera imikorere yayo mu buryo butunguranye, no gutuma imitsi idakora neza, inanirwa, bigaherekezwa no kunyeganyega no gucika intege. Byagaragaye ko nicotine acetylcholine receptor (nChR) yahoraga ikora kugira ngo itume acetylcholine (Ach) irekurwa igihe kirekire. Polycidin kandi ikora kuri aside γ-aminobutyric (GAGB) receptors, ihindura imikorere y’imiyoboro ya GABA gated chlorine kandi ikongera imikorere yayo yo kwica udukoko.

Inzira yo kwangirika

Ibisigazwa by'imiti yica udukoko mu bidukikije bivuga "umutwaro ntarengwa" w'imiti yica udukoko ibidukikije bishobora kuba birimo, ni ukuvuga mu gace runaka no mu gihe runaka, haba mu rwego rwo kwemeza ubuziranenge bw'ibinyabuzima n'umusaruro w'ibikomoka ku buhinzi ndetse no kudahungabanya ubuziranenge bw'ibidukikije. "Umutwaro ntarengwa" na wo ni agaciro gasanzwe ko gupima umutekano w'imiti yica udukoko mu bidukikije, kandi ni ikintu kigenda kigabanuka buhoro buhoro uko igihe n'imiterere y'ibidukikije bihinduka. Igihe cyose itarenze uyu mubare, ubushobozi bw'imiti yica udukoko mu bidukikije burasabwa. Polycidin irangirika vuba mu bidukikije binyuze mu nzira zitandukanye zivanze, cyane cyane iyangirika ry'izuba no kwangirika kwa mikorobe, hanyuma igahinduka ibice karemano nka karubone, hidrojeni, ogisijeni, na azote, bityo ntihagire umwanda ku bidukikije. Igihe cyo kwangirika kw'izuba cya polycidin mu butaka cyari iminsi 9 kugeza 10, icy'ubuso bw'amababi cyari iminsi 1.6 kugeza 16, naho icy'amazi cyari munsi y'umunsi 1. Birumvikana ko igice cy'ubuzima gifitanye isano n'ubukana bw'urumuri, iyo hatabayeho urumuri, igice cy'ubuzima cya multicidin binyuze mu mikorere y'ubutaka ni iminsi 9 kugeza kuri 17. Byongeye kandi, igipimo cyo kohereza ubunini bw'ubutaka cya polycidin ni K iri hagati (5 ~ 323), ubushobozi bwayo bwo gushonga mu mazi ni buke cyane kandi bushobora kwangirika vuba, bityo ubushobozi bwo kuyungurura bwa polycidin ni buke cyane, bityo ishobora gukoreshwa mu buryo bushyize mu gaciro gusa, kandi ni n'umutekano ku masoko y'amazi yo munsi y'ubutaka.
