Emodin methyl ether yog cov nroj tsuag muaj zog heev -raws li fungicide. Nws tau muab rho tawm los ntawm cov nroj tsuag ntuj xws li rhubarb, thiab ua tiav kom tau nws cov khoom xyaw nquag. Nws muaj kev tswj zoo heev ntawm cov kab mob mildew, downy mildew, grey pwm, anthracnose, thiab lwm yam. Nws tsis tshua muaj toxicity rau tib neeg thiab tsiaj txhu thiab tus phooj ywg rau ib puag ncig, thiab tshwj xeeb tshaj yog tsim rau ntsuab thiab organic zaub ntau lawm. Emodin methyl ether yog cov tshuaj tiv thaiv fungicide uas ua rau cov nroj tsuag tsim cov lus teb tiv thaiv, inhibits kev loj hlob ntawm cov kab mob spores, kev loj hlob ntawm hyphae, thiab tsim cov appressoria, yog li tiv thaiv cov nroj tsuag los ntawm cov kab mob tua thiab ua tiav cov kab mob tiv thaiv.

Action mechanism: Nws belongs rau cov nroj tsuag -raws li cov tshuaj tua kab thiab muaj cov khoom ua haujlwm. Nws tsuas yog inhibits oxidation thiab dehydrogenation ntawm cov suab thaj thiab qab zib metabolism hauv cov khoom nruab nrab ntawm cov kab mob, thiab inhibits synthesis ntawm cov protein thiab nucleic acids. Nws muaj kev tswj zoo los ntawm dib powdery mildew.

Ntuj anthraquinone tebchaw muaj qhov tseem ceeb tshaj plaws inhibitory nyhuv ntawm pathogen txoj kev loj hlob ua ntej cov kab mob invades, uas yog, ua ntej tsim ntawm appressoria protoplasts. Cov txheej txheem ntawm kev ua nyob rau hauv kev cuam tshuam loj heev ntawm kev loj hlob thiab txuas ntawm spores ntawm pathogenic fungi thiab tsim ntawm appressoria protoplasts, ua rau feem ntau ntawm cov txuas protoplasts yuav txawv txav thiab tsis tuaj yeem tsim appressoria protoplasts.

Nws tsis tsuas yog inhibits germination thiab loj hlob ntawm fungi, tab sis kuj induces cov nroj tsuag los tsim kev nyuaj siab- tiv thaiv tiv thaiv teb.

Nws muaj kev tswj cov teebmeem ntawm powdery mildew ntawm feem ntau cov qoob loo, thiab tseem muaj kev tswj zoo ntawm cov kab mob downy mildew, grey pwm, anthracnose, thiab lwm yam.

Kev ua haujlwm siab thiab muaj zog persistence

Tsis muaj kev cuam tshuam - ua haujlwm nrog lwm cov tshuaj lom neeg

Nws yuav tsum tau muab tshuaj tsuag ua ntej lossis nyob rau theem pib ntawm cov kab mob tshwm sim. Nws tuaj yeem txau 2-3 zaug tsis tu ncua, nrog rau lub sijhawm kwv yees li 7 hnub . 2. Nws raug nquahu kom siv cov khoom no thaum pib ntawm cov pwm pwm. Daim ntawv thov txheej txheem yog txau . 3. Lub sijhawm zoo tshaj plaws rau kev txau yog nyob rau hauv qhov tsis muaj cua los yog lub teeb cua tsis muaj dew.
