Vim qhov kub thiab av noo, kab tsuag thiab kab mob tuaj yeem tshwm sim, tshwj xeeb tshaj yog grey pwm. Kev puas tsuaj yog zuj zus zuj zus txhua xyoo thiab tau dhau los ua ib qho ntawm cov kab mob nyuaj tshaj plaws kom tshem tawm hauv tsev cog khoom cog zaub. Niaj hnub no, kuv xav kom tus neeg sawv cev zoo tshaj plaws rau kev tiv thaiv thiab kho cov pwm grey -boscalid ua. Nws muaj kev tiv thaiv, kho thiab tshem tawm cov teebmeem ntawm grey pwm.
1. Mechanism ntawm kev ua
Boscalid feem ntau inhibits cov synthesis ntawm succinate dehydrogenase, ib qho khoom siv hluav taws xob hauv mitochondria ntawm cov kab mob, kom cov amino acids, qab zib thiab lwm yam khoom tsis tuaj yeem ua ke, cuam tshuam nrog kev faib tawm ntawm tes thiab kev loj hlob, thiab ua tiav lub hom phiaj ntawm kev tua cov kab mob. Nws muaj kev tiv thaiv, tiv thaiv thiab kho cov teebmeem ntawm grey pwm, sclerotinia, powdery mildew thiab ntau lwm yam kab mob.
2. Cov yam ntxwv tseem ceeb
(1) Broad fungicide spectrum: Boscalid yog ib qho dav-spectrum fungicide uas tuaj yeem tiv thaiv thiab kho ntau tshaj 10 kab mob xws li pwm grey, sclerotinia, powdery mildew, hauv paus rot, thaum ntxov blight, thiab lwm yam. Nws muaj kev tiv thaiv zoo thiab kho cov teebmeem, tshwj xeeb tshaj yog rau grey pwm.
(2) Tsis muaj qhov sib txawv: Boscalid yog tiam tshiab ntawm amide fungicides. Nws tsis muaj qhov cuam tshuam nrog cov tshuaj fungicides xws li cyproconazole, procymidone, thiab pyrimethanil. Nws yog thawj qhov kev xaiv rau kev kho mob ntawm resistant grey pwm.
(3) Muaj zog permeability: Boscalid muaj permeability zoo thiab ntsug permeability. Nws tuaj yeem nkag mus los ntawm cov ntaub so ntswg mus rau sab nraum qab ntawm nplooj, ua tiav cov txiaj ntsig ntawm kev kho tus kab mob los ntawm nplooj.
(4) Kev kho kom zoo dua: Boscalid feem ntau tua cov kab mob los ntawm inhibiting cov synthesis ntawm cov tshuaj hauv mitochondria ntawm cov kab mob. Nws muaj cov nyhuv tua zoo rau txhua theem ntawm cov kab mob. Kev kho mob zoo dua.
(5) Kev ua haujlwm zoo: Boscalid tuaj yeem xa mus rau nplooj nplooj thiab nplooj nplooj ntawm cov nroj tsuag los ntawm xylem, uas tuaj yeem tiv thaiv tau zoo dua thiab tswj cov kab mob tshwm sim hauv ntau qhov chaw ntawm cov nroj tsuag.
(6) Kev sib raug zoo: Boscalid tuaj yeem sib xyaw nrog ntau hom fungicides xws li azoxystrobin, pyraclostrobin, procymidone, fludioxonil, thiab lwm yam, uas tsis tsuas yog nthuav tawm cov kab mob fungicide nkaus xwb tab sis kuj txo cov tshuaj tiv thaiv kab mob.
3. Cov qoob loo siv tau
Nws yog tsuas yog siv rau kev tiv thaiv thiab tswj cov kab mob ntawm cov qoob loo xws li rapeseed, dib, lws suav, kua txob, eggplant, grape, thiab lwm yam.
4. Tswj lub hom phiaj
Nws yog tsuas yog siv los tiv thaiv thiab tswj ntau yam kab mob xws li grey pwm, powdery mildew, rot, hauv paus rot, thaum ntxov blight, thiab sclerotinia. Nws yog tshwj xeeb tshaj yog zoo tiv thaiv grey pwm ntawm txiv lws suav, cucumbers, strawberries, thiab sclerotinia ntawm rapeseed thiab eggplant.
5. Kev siv tshuab
(1) Txhawm rau tiv thaiv thiab tswj cov pwm grey ntawm tsev cog khoom zaub xws li dib, txiv lws suav, kua txob, strawberries, thiab eggplants, 30 mus rau 60 ml ntawm 38% azoxystrobin · boscalid ncua kev kawm yuav siv tau rau thaum ntxov ntawm tus kab mob, tov nrog 30 kg dej thiab txau tusyees, uas tuaj yeem tswj tau qhov kev puas tsuaj thiab kis ntawm cov pwm grey. Kev tiv thaiv tuaj yeem ncav cuag ntau dua 98%.
(2) Txhawm rau tiv thaiv thiab tswj sclerotinia rot ntawm cov qoob loo xws li eggplant thiab rapeseed, 30-50 g / mu ntawm 50% boscalid water-dispersible granules siv tau, diluted nrog 30-40 liters dej. Qhov no tuaj yeem tiv thaiv thiab tswj tau qhov kev puas tsuaj txuas ntxiv ntawm sclerotinia rot, nrog kev tiv thaiv ntau dua 85%.
