Fludioxonil tuaj yeem cuam tshuam thiab tua cov kab mob.Cov txheej txheem bactericidal yog cuam tshuam thiab rhuav tshem cov kab mob oxidation thiab biosynthesis txheej txheem ntawm

cov kab mob, rhuav tshem cov saw hydrophobic ntawm cov cell membrane ntawm cov kab mob, thiab oxidize thiab yaj cov ntsiab lus tseem ceeb ntawm lub neej kev ua ub no ntawm cov kab mob.

Phosphorylation-txog kev hloov ntawm cov piam thaj kom ntes cov kab mob mycelium loj hlob.

Fludioxonil tuaj yeem siv los ua cov noob txheej, txau, thiab cov hauv paus irrigation, thiab nws muaj txiaj ntsig zoo tiv thaiv blight, cag rot, grey pwm, thiab fungus uas tshwm sim hauv ntau cov qoob loo.

Kab mob Nuclear thiab Fusarium wilt muaj kev tswj xyuas.

Dab tsi yog kev ua haujlwm thiab kev siv ntawm fludioxonil

1. Muaj nuj nqi

(1) Fludioxonil muaj cov kab mob bactericidal thiab tshuaj tua kab mob.Rau Botrytis cinerea, nws cov kab mob bactericidal yog los cuam tshuam thiab rhuav tshem nws cov oxidation lom.

thiab cov txheej txheem biosynthesis (uas yog, yaj lub cell phab ntsa ntawm Botrytis cinerea) thiab sai ua kom puas cell membrane ntawm Botrytis cinerea Nws oxidizes thiab

dissolves cov ntsiab lus tseem ceeb ntawm lub neej kev ua ub no ntawm cov kab mob, thiab rhuav tshem cov synthesis ntawm nucleic acid thiab proteins.

(2) Fludioxonil inhibits kev loj hlob ntawm fungal mycelium los ntawm inhibiting kev hloov mus rau cov piam thaj phosphorylation, thiab nws thiaj li ua rau cov kab mob tuag.

Tuag.

2. Lub hom phiaj

(1) Fludioxonil tsis muaj qhov cuam tshuam nrog cov tshuaj fungicides uas twb muaj lawm, thiab tuaj yeem siv los ua cov tshuaj tua kab mob thiab cov tshuaj tua kab mob tshem tawm.Thaum kho cov

cov noob, cov khoom xyaw nquag yuav tsuas yog nqus tau me me xwb, tab sis nws tuaj yeem tua cov kab mob ntawm qhov chaw ntawm cov noob thiab hauv lub tsho tiv no ntawm cov noob.

(2) Thaum siv fludioxonil rau irrigate cov hauv paus hniav lossis kho cov av, nws tuaj yeem tiv thaiv thiab tswj cov hauv paus rot, fusarium wilt, blight, blight thiab lwm yam kab mob.

ntawm ntau yam qoob loo.Thaum txau, nws tuaj yeem tiv thaiv sclerotinia, grey pwm thiab lwm yam kab mob.

Yuav siv li cas fludioxonil

1. Txheej

Thaum cog pob kws, qos yaj ywm, nplej, taum pauv, qej, dib, txiv laum huab xeeb, melons, watermelons thiab lwm yam qoob loo, siv lawv ua ntej sowing.

2.5% fludioxonil ncua kev tshem tawm cov noob txheej rau cov noob hnav khaub ncaws, qhov sib piv ntawm cov kua rau cov noob yog 1: 200-300.

2. Npua paj

(1) Thaum cog peppers, eggplants, watermelons, txiv lws suav, zucchini, strawberries, dib, melons thiab lwm yam qoob loo, siv 2.5% fludioxonil suspension

concentrate 200 zaug (10ml tshuaj tov nrog 2kg dej) + 0.1% forchlorfenuron dej Dip paj nrog 100-200 zaug ntawm tus neeg sawv cev.

(2)Tom qab dipping paj, nws tuaj yeem tiv thaiv pwm grey, ua kom cov paj ntoo tshiab rau lub sijhawm ntev, thiab tiv thaiv zaub xws li eggplants thiab txiv lws suav los ntawm rotting.

3. Txau

Nws tuaj yeem siv rau theem pib ntawm tus kab mob los tiv thaiv grey pwm ntawm txiv hmab txiv ntoo, strawberries, peppers, eggplants, dib, txiv lws suav, txiv lws suav thiab lwm yam qoob loo.

2000-3000 zaug ua kua ntawm 30% pyridoyl·fludioxonil ncua kev kawm ntawv mloog zoo yuav tsum tau txau ib zaug txhua 7-10 hnub.

4. Kev ywg dej hauv paus

Txhawm rau tiv thaiv fusarium wilt thiab hauv paus rot nyob rau hauv eggplant, watermelon, dib, lws suav, strawberry thiab lwm yam qoob loo, cov hauv paus hniav yuav irrigated nrog 800-1500 zaus ntawm 2.5%.

fludioxonil ncua kev mloog zoo nyob rau hauv thaum ntxov theem ntawm tus kab mob, ib zaug txhua txhua 10 hnub, thiab nruam irrigation 2-3 zaug.
