Masangano epasi rose akati wandei akafanotaura mukana wemamiriro ekunze akanyanyisa uye anoparadza pasi rose mumwedzi ichangopfuura.

Irizvino gore rinodziya zvakanyanya pane rekodhi raive 2015-2016, apo nyika yakasangana neEl Nino yemwedzi makumi maviri nerimwe, maererano nemushumo wakabudiswa neWorld Meteorological Organisation muna Chivabvu.

Mukupera kwaChikumi, bepanhau reNature rakashuma kuti kana El Nino yakanyanya, ine mukana wekusundidzira tembiricha yepasirese kurekodha kana pedyo-rekodhi yakakwirira muna 2024.

Musi waChikunguru 4, World Meteorological Organisation yakagumisa kuti yekutanga El Nino chiitiko munzvimbo inopisa yePacific Ocean mumakore manomwe, uye pasi rose richava nemamiriro ekunze anoparadza uye maitiro emamiriro ekunze anenge aine chokwadi.

Mimwe mishonga inokonzeresa kukuvadza pakupisa kwakanyanya kunyanya nekuda kwemapoinzi maviri anotevera:

Kutanga, inoenderana nemhando yemushonga

Inorganic mishonga yekuuraya zvipembenene uye inonyungudika nemvura, mishonga yezvipembenene inopindika, yakadai semhangura sulfate, sulfur poda, musanganiswa wesarufa wematombo, unoshandiswa pakupisa kwakanyanya, zviri nyore kukonzeresa kukuvadzwa kwemishonga kune zvirimwa, nekuti kugadzikana kwechimiro chemakemikari kuchachinja mushure mekupisa. imwe tembiricha, zvichikonzera kukuvara kwezvinodhaka.

Chechipiri, ine chekuita nekuramba zvirimwa

Kuramba kwemishonga yemiti yemashizha edehwe yakadai seBuxus macrophylla yakasimba, uye kurwisa kwemishonga yemiti ine cuticle yakatetepa haina simba, uye zviri nyore kugadzira kukuvara kwemishonga kana ichishandiswa mumamiriro ekunze ekupisa.

1. Abamectin

Abamectin mushonga unouraya tumbuyu, mite nenematode, uye unogona kushandiswa kudzora tumbuyu pamiti yakasiyana siyana. Inogona kunge iri mumhando dzakanakisa kana 20 ℃, asi inofanirwa kutarisisa kune yakanyanya tembiricha, kunyanya 38 ℃ pamusoro penguva yekushandiswa, zviri nyore kukonzeresa kukuvara kwezvinodhaka, chirimwa mashizha kuremara, mavara, chiitiko chekumira kukura. .

2.Pyraclostrobin

Pyraclostrobin is wide spectrum fungicide, ine kurapa uye kudzivirira. Pachava nengozi yekukuvara kwezvinodhaka kana ukashandisa high concentration.Zvinogona kukonzera mashizha ekupisa mashizha.

3.Nitenpyram

Nitenpyram inonyanya kushandiswa kudzora zvipembenene zvinoruma uye nyore kukonzera kukuvara kwezvinodhaka pakupisa kwakanyanya, saka inofanira kudzivirirwa. Uye zviri nani kupfapfaidza patembiricha iri pasi pe30 ° C izvo zvisingakonzere kutsva kwemashizha uye zvimwe zviitiko.

4.Chlorfenapyr

Chlorfenapyr inouraya zvipembenene zvakakura, kunyanya kurwisa zvipembenene zvakura zve lepidoptera (rapeseed, beet moth, nezvimwewo). Chlorfenapyr, yakakodzera tembiricha anenge 20-30 madhigirii, yakanakisa mhedzisiro. Zvisinei, kushandiswa kweChlorfenapyr pakupisa kwepamusoro kunogona kukonzera kupisa kwemashizha; Mashizha manyoro ari pamusoro anewo kukuvara kwakanyanya kwezvinodhaka.

5. Fluazinam

Fluazinam inogona kudzivirira zvakanyanya kuzvimba midzi chirwere uye grey mold, uye inogona kudzivirira tupukanana, senge citrus red spider (mukuru, zai), uye kudzora mhedzisiro iri nani. Fluazinam ichawedzera mukana wekukuvara kwezvinodhaka kana ichishandiswa mukupisa kwepamusoro, nokuti basa reFluazinam rakakwirira zvikuru. Mushonga wekushisa wepamusoro unogona kukurumidza kubuda kwemvura, zvakaenzana nekuwedzera kuwanda kwemushonga wemvura.

6.Propargite

Propargite iri mune yakaderera chepfu acaricide, ine kusangana uye gastric toxicity, uye osmotic conduction. Inogona kudzivirira zvipembenene zvine simba pamusoro pe20 ℃ nepo muchero wechirimwa uri nyore kuburitsa chirwere chekupiswa nezuva pamusoro pe25 ℃.

7.Diafenthiuron

Diafenthiuron rudzi rutsva rwetiourea zvipembenene, acaricide, uye ine imwe mhedzisiro yekuuraya mazai. Munguva yekushisa kwepamusoro (pamusoro pe30 ℃) uye mamiriro ehunyoro hwepamusoro, inoburitsa kukuvara kwezvinodhaka pakudyara mbesa.

Izvo zvinofanirwa kucherechedzwa kuti yakakodzera tembiricha yekushandisa yevamiriri vari pamusoro ndeyekutarisa chete, uye chaiyo tembiricha inodawo kukamurwa kuita zvirimwa, uye tembiricha yakakodzera yezvimwe zvirimwa zvakare zvakasiyana.

Asi 2,4D, Glyphosate uye Chlorpyrifos inobatsira zvikuru muzhizha.
