Hauv paus-knot nematodes, sclerotinia, powdery mildew, grey pwm, thaum ntxov blight, thiab lwm yam yog cov kab mob loj tshaj plaws uas tshwm sim rau ntau cov qoob loo. Cov kab mob no tshwm sim los ntawm kev sib kis sai, kev puas tsuaj loj, thiab nyuaj rau kev tshem tawm. Hauv particular, cov kab mob hauv paus-knot nematode feem ntau ua rau cov hauv paus hniav puas tsuaj, ua rau nws txoj kev tiv thaiv thiab kev tswj hwm nyuaj, ua rau mob taub hau zoo rau cov neeg ua liaj ua teb. Niaj hnub no, kuv xav qhia rau koj ib tug zoo heev fungicide-Fluopyram. Koj tsuas yog yuav tsum tau poob cov hauv paus hniav nrog tus neeg sawv cev no kom ua tiav cov txiaj ntsig zoo dua.
1. Taw qhia txog tshuaj
Fluopyram yog qhov tseeb bactericidal nematicide tsim los ntawm Bayer Company, nrog rau cov npe lag luam "Lufuda" thiab "Baibaike". Nws muaj cov txiaj ntsig zoo hauv kev tswj cov hauv paus-knot nematodes, grey pwm, powdery mildew, nplooj pwm, grey pwm thiab lwm yam kab mob. Tshwj xeeb tshaj yog nyob rau hauv kev tswj cov hauv paus-knot nematodes, nws yog ib tug npaum, tsawg-tshuaj lom, environmentally phooj ywg nematicide.
2. Mechanism ntawm kev ua
Fluopyram yog succinic acid inhibitor. Cov kab mob xav tau ntau lub zog thaum lawv ua haujlwm. Lub zog yog tsim los ntawm mitochondria. Muaj qee cov enzymes hauv daim nyias nyias ntawm mitochondria. Cov enzyme no hu ua succinic acid active enzyme. Kev hloov hluav taws xob yuav tsum dhau los ntawm ntau lub rooj vag thiab hloov pauv los ntawm cov enzymes ua ntej lub zog tuaj yeem tsim tawm thaum kawg.
Fluopyram inhibits qhov kev ua ntawm succinate dehydrogenase rau ntawm daim nyias nyias ntawm mitochondria thiab tiv thaiv kev hloov hluav taws xob, yog li cuam tshuam nrog lawv txoj kev ua pa thiab ua tiav lub hom phiaj ntawm kev tua kab mob. Tom qab nematodes raug kho nrog fluopyram, lawv lub cev nrawm nrawm rau hauv cov duab zoo li rab koob thiab lawv cov haujlwm txo qis. Ceev ceev tua kab thiab kab mob.
3. Cov yam ntxwv tseem ceeb
(1) Sterilize thiab tua kab: Fluopyram tuaj yeem siv los tswj ntau tshaj 10 kab mob xws li powdery mildew, grey pwm, nplooj pwm, sclerotinia, thiab nplooj nplooj. Nws tseem tuaj yeem tswj tau cov hauv paus-knot nematodes, uas yog qhov nyuaj tshaj plaws los tswj.
(2) Kev ua haujlwm siab heev: Fluopyram muaj zog heev. Lwm yam tshuaj tua kab rau kev tswj cov hauv paus-knot nematodes yog xam nyob rau hauv kilograms, tab sis fluopyram yog xam nyob rau hauv milligrams. Ib tsob nroj tsuas yog xav tau 0 xwb.
(3) Cov nyhuv ntev ntev: Fluopyram muaj cov khoom siv hluav taws xob zoo. Fluopyram muaj kev ruaj ntseg zoo hauv cov av thiab tuaj yeem nqus tau los ntawm cov cag qoob loo kom ua tiav lub hom phiaj ntawm cov tshuaj tua kab thiab cov kab mob bactericidal. Lub sijhawm zoo ntawm kev tswj cov hauv paus-knot nematodes tuaj yeem ncav cuag ntau dua 80 hnub.
(4) Kev ua haujlwm siab thiab tsis muaj tshuaj lom: Raws li kuv lub teb chaws cov tshuaj tua kab toxicity faib, fluopyram yog cov tshuaj tua kab mob uas tsis muaj tshuaj lom thiab nematicide, thiab tam sim no tsuas yog cov tshuaj tua kab mob tsis zoo, tsis muaj tshuaj lom nematicide.
4. Cov qoob loo siv tau
Fluopyram tuaj yeem siv dav hauv cov nplej, txiv laum huab xeeb, txiv lws suav, dib, txiv tsawb, melons, zaub qhwv, txiv hmab txiv ntoo thiab lwm yam qoob loo. Txawm li cas los xij, txij li cov tshuaj tseem nyob hauv lub sijhawm tiv thaiv patent, tus nqi kuj tseem ceeb thiab tus nqi yog qhov tseeb siab. Tam sim no, nws tsuas yog siv rau cov qoob loo nyiaj ntsuab nrog cov nqi ntxiv xws li txiv lws suav, dib, txiv lws suav, melons, thiab txiv hmab txiv ntoo.
5. Tiv thaiv thiab tswj cov khoom
Feem ntau siv los tswj cov hauv paus-knot nematodes, powdery mildew, grey pwm, nplooj pwm, sclerotinia, nplooj ntoos, xim av rot thiab lwm yam kab mob.
6. Siv tshuab
(1) Kev tiv thaiv thiab tswj cov kab mob hauv paus-knot nematode nyob rau hauv dib, watermelon, lws suav, eggplant, strawberry thiab lwm yam qoob loo:
Thaum cog, dipped cov hauv paus hniav nrog 41.7% fluopyram ncua 1000 zaug ua ntej cog, los yog irrigate cov hauv paus hniav nrog 41.7% fluopyram ncua 15000 mus rau 20000 zaug, 200 ml ib tsob nroj, thiab ces npog nrog av. Nws tuaj yeem tiv thaiv kev puas tsuaj ntawm cov hauv paus pob txha nematodes, powdery mildew, grey pwm, sclerotinia, xim av rot, nplooj nplooj thiab lwm yam kab mob thiab kab kab, thiab lub sij hawm ntawm cov nyhuv tuaj yeem ncav cuag ntau tshaj 80 hnub.
(2) Txhawm rau tiv thaiv thiab tswj cov kab mob xws li pwm mildew, grey pwm, anthracnose, thiab vine blight nyob rau hauv dib, txiv lws suav, txiv lws suav, strawberries, thiab lwm yam qoob loo, 35% fluorobacteria·tebuconazole ncua 25-30 ml / acre yuav ua tau. siv. Sib tov 30 mus rau 40 kilograms ntawm dej thiab tshuaj tsuag tusyees kom tswj tau qhov tshwm sim thiab kis ntawm cov kab mob saum toj no.
