(4) Pyraclostrobin lub zog muaj zog tso cai rau nws ua raws li cov nplooj nplooj, ua kom nws cov txiaj ntsig tiv thaiv thiab lub sijhawm ua haujlwm. Txawm li cas los xij, kev pheej hmoo ntawm phytotoxicity yuav tsum tau sau tseg. Tshwj xeeb tshaj yog thaum lub sij hawm yub theem hauv chaw zov me nyuam, thaum cov qoob loo loj hlob muaj zog thiab cov xwm txheej kub thiab av noo, ntau ntau ntawm pyraclostrobin tuaj yeem ua rau muaj kev pheej hmoo ntawm phytotoxicity.
Cov kev ceev faj
(1) Pyraclostrobin yog tshuaj lom rau cov kab mob hauv dej xws li ntses thiab cw. Nws yuav tsum tsis txhob siv nyob ze cov pas dej ntses lossis hauv cw- nplej teb. Thaum siv ua ke nrog lwm tus neeg sawv cev thaum lub sij hawm yub thiab cov tub ntxhais hluas txiv hmab txiv ntoo theem ntawm cov qoob loo, qhov ntau npaum li cas yuav tsum tau txo kom tsim nyog, tshwj xeeb tshaj yog thaum tov nrog emulsifiable concentrates. Thaum tov nrog emulsifiable concentrates los yog organophosphate tshuaj tua kab, txiv hmab txiv ntoo hlawv tej zaum yuav tshwm sim ntawm jujube, txiv tsawb, thiab mango ntoo.
(2) Vim yog kev siv tas li ntau xyoo thiab cov yam ntxwv ntawm cov khoom, txawm hais tias pyraclostrobin muaj qhov cuam tshuam ntev, nws ib leeg - cov tshuaj kho mob tsis zoo, thiab nws cov txiaj ntsig tau qeeb. Nws yog siv ntau dua los tiv thaiv thiab yuav tsum tau siv ua ntej lossis thaum pib ntawm tus kab mob tshwm sim. Nws yog qhov zoo tshaj plaws siv ua ke nrog ntau hom fungicides.
