Unoziva here mushonga unouraya zvipembenene unonzi dimethoate? Izvi zvine simba kwazvo kuzvipukanana zvakawanda zvinogona kukonzeresa kukuvara kwakasiyana mumiti iyo iwe yaunorima muminda yako uye minda yemichero uye inoshandiswa zvakanyanya pamhando dzakasiyana dzinoitisa kuti ibatsire zvikuru.
Pakati peiyi inguva yayo yakareba uye kugona kwayo kutsakatisa huwandu hukuru hwevamiriri vekunze vanogona kuunza matambudziko munzvimbo dzako dzekunze. Muchikamu chino isu tinokuudza kuti chii uye kuti ndezvipi zvinoshandiswa, kuitira kuti iwe ugone kuongorora kana ichi chipembenene chine simba chiri izvo zvaunoda kuchengetedza zvirimwa mubindu rako.
Chii chinonzi dimethoate?
Kana iwe uri munyika yebhotani, iwe unogona kunge uchitozviziva, nekuti dimethoate iri mushonga une simba unoshandiswa zvakanyanya kuitira kuti ubvise zvipuka zvisingaverengeki zvinowanzo bata zvakananga zvirimwa zvakasiyana, zvichitotungamira mukuparadzwa kwavo kwese.
Ndokusaka mushonga uyu uchishandiswa, unova Yakagadziriswa nekambani yeAmerica muna 1950. Basa rayo rakakura semushonga unouraya zvipembenene wakamira pakuve yakakosha inhibitor ye acetylcholinesterase, iyo inosanganisira enzyme iyo inodzora mashandiro akanaka epakati sisitimu yemidziyo yezvirimwa.
Ichi chipembenene chinoiswa nyore nyore pazvirimwa zvemiti, kuwana kunonoka nekukurumidza uye kugovera izvo zvinofukidza nzvimbo dzese dzemuti, kuitira kuti kana chipembenene cheimwe denda chauya kuzodya mashizha, maruva kana michero yakafanana, vanomwisa mushonga uyu uyo muchetura uchauparadza.
Dimethoate inozivikanwa nehupenyu hwezvekurima hwenyika dzese dzepasirese, uko kwakapihwa mvumo yekushandisa kwayo kune huwandu hwakakosha hwemhando dzezvipembenene.
Asi izvi hazvireve kuti haugone kushandisa mushonga uyu pane mamwe marudzi ezvipembenene zvisingazivikanwe uye uwane mhedzisiro. Zvirokwazvo mumatunhu akasiyana ichave inogoneswa iyo shandisa uye chengetedza mumhando dzakasiyana dzezvipembenene, asi kunyanya muEuropean Union zviyero uye mvumo yekushandisa kwayo zvakagadziriswa.
Zvipukanana zvinodzorwa ne dimethoate
Kune husingagumi hwezvipembenene izvo zvinogona kurapwa neizvi mushonga une simba, Pakati pedu patinogona kuratidza: olive tree spider mite, olive tree borer, olive tree borer, orange cacoecia or carnation miner, almond tree bug beet, cottony orange and vine mealybug, red mealybug of the citrus or citrus red louse, pink worm, etc.
Inofanira kuonekwa kuti izvi ndezvimwe zvezvipembenene zvinogona kubviswa nemhando iyi yemakemikari uye rondedzero inoenderera nemamwe marudzi mazhinji uye zvipembenene zvinorwisa zvirimwa zvakasiyana.
Kukanganisa kwazvinoita nharaunda
Nezve kuguma kwezvakatipoteredza kwedimethoate, uku kune kushingirira kushoma mune zvakatipoteredza, asi kana iine mukurumbira wekushingirira muvhu, kwainogona kuwanikwa kwemazuva matatu munzvimbo idzo dzinonaya.
Munzvimbo dzinonaya dzinogona kuramba dziripo kwemazuva zana nemakumi maviri.. Zvisinei, ino inguva inofungidzirwa uye kazhinji nguva yeiyi chipembenene muvhu ingangoita mazuva makumi maviri.
Mumvura yemvura, dimethoate inogona kuramba ichidarika rinopfuura vhiki, asi izvi hazvireve kuti zvinoramba zvichirarama munzvimbo dzakakomberedzwa nekuda kwekuti ivo vane hunyoro, nekuti mumhepo ine hunyoro ichave yakashatiswa nemakemikari ne oxidation uye hydrolysis maitiro.
Yayo biodegradation muvhu inoenderana neayo alkalinity. Izvi zvinoreva kuti kudzikisira kunouya nekukurumidza zvakanyanya muvhu iro mune alkaline pH. Mumitumbi ine aqueous, haina kuratidza kusungirirwa kumatope, ichikurumidza kudzikisira nemaitiro akasiyana ehupenyu uye emakemikari, ichibatsirwa ne volatilization uye hydrolysis maitiro.
