1. Taw qhia

Pyrethrins 50% 8003-34-7 ispesticide pom muaj nyob hauv qee cov paj chrysanthemum. Lawv yog cov sib xyaw ntawm 6 cov tshuaj uas muaj tshuaj lom rau cov kab. Nws' yog cov khoom siv tseem ceeb rau kev npaj yoov tshaj cum, thiab yog cov tshuaj tua kab mob uas muaj nyob rau hauv perennial herbaceous pyrethrum ntawm Compositae tsev neeg. Feem ntau muaj pyrethrin I thiab pyrethrin II, thiab ib qho me me ntawm pyrethrin I thiab pyrethrin II nrog cov qauv zoo sib xws. Tam sim no, ntau cov tebchaw zoo ib yam li cov pyrethrins ntuj tau raug tsim los ua cov tshuaj tua kab, sib sau ua ke hu ua pyrethroids. Pyrethrin yog cov kua qaub daj uas muaj roj nrog cov tshuaj tsw qab. Nws' s insoluble hauv dej, soluble hauv ntau cov kuab tshuaj organic. Nws' tsis ruaj khov, decomposes thiab ua tsis tiav thaum raug alkali, thiab decomposes thiab tsis nyob rau hauv lub teeb muaj zog lossis kub.

Application of Pyrethrins 50% 8003-34-7

pyrethrins 50% 8003-34-7 ua haujlwm li cas?

Pyrethrins 50% 8003-34-7 excite lub paj hlwb ntawm kab uas kov los yog noj nws. Qhov no sai sai ua rau tuag tes tuag taw thiab thaum kawg lawv tuag. Pyrethrins feem ntau sib xyaw nrog lwm cov tshuaj los ua kom lawv cov nyhuv. Qhov thib ob tshuaj no yog hu ua ib tug synergist.

Yuav ua li cas tshwm sim rau pyrethrins 50% 8003-34-7 nyob rau hauv ib puag ncig?

Nyob rau hauv lub xub ntiag ntawm tshav ntuj, pyrethrin 1, ib feem ntawm pyrethrins, lov sai sai nyob rau hauv dej thiab nyob rau hauv cov av thiab cov nroj tsuag. Ib nrab-lub neej yog 11.8 teev hauv dej thiab 12.9 teev ntawm cov av. Ntawm cov qos yaj ywm thiab txiv lws suav, tsawg dua 3% tseem nyob tom qab 5 hnub. Pyrethrins tsis nkag mus rau hauv cov nroj tsuag.

Thaum tsis muaj lub teeb, pyrethrin 1 tawg qeeb qeeb hauv dej. Ib nrab ntawm 14 mus rau 17 hnub tau tshaj tawm. Thaum dej acidic ntau dua, pyrethrin 1 tsis tuaj yeem tawg. Pyrethrins uas nkag mus rau hauv dej tsis yaj zoo tab sis zoo li khi rau sediment. Ib nrab-lub neej ntawm pyrethrin 1 nyob rau hauv sediment yog 10.5 rau 86 hnub.

Pyrethrins kuj lo rau hauv av thiab muaj peev xwm qis heev los ntawm cov av mus rau hauv av. Hauv kev tshawb fawb teb, pyrethrins tsis pom hauv qab av qhov tob ntawm 15 centimeters. Txawm li cas los xij, pyrethrins tuaj yeem nkag mus rau hauv dej los ntawm av yaig lossis drift. Hauv cov txheej saum toj kawg nkaus ntawm cov av, pyrethrins tau tawg sai sai los ntawm microbes. Av ib nrab-lub neej ntawm 2.2 mus rau 9.5 hnub tau tshaj tawm. Pyrethrins muaj peev xwm ua tau vapor hauv huab cua.

Ua taupyrethrins 50% 8003-34-7cuam tshuam rau noog, ntses, lossis lwm yam tsiaj qus?

Pyrethrins 50% 8003-34-7 yog xyaum tsis muaj tshuaj lom rau cov noog tab sis muaj kuab heev rau cov muv. Txawm li cas los xij, qee qhov kev pheej hmoo rau pollinators tsuas yog txwv los ntawm lawv cov kev ua haujlwm me me thiab kev tawg sai.

Nws' s heev heev rau cov ntses heev. Nws' Nws kuj muaj tshuaj lom heev rau lobster, cws, oysters, thiab kab dej. Qhov no tej zaum yuav yog ib feem vim lawv cov toxicity ntau dua ntawm qhov kub thiab txias. Muaj pov thawj tias qhov ntev ntev ntawm cov pyrethrins tuaj yeem ua rau muaj kev loj hlob ntawm cov ntses thiab kab hauv dej. Hauv kev tshawb fawb cais, minnows thiab dej fleas tau raug rau cov pyrethrins tsawg heev rau ib hlis. Tsawg minnow qe hatched thiab tsawg dua dej flea hluas raug tsim.
