Ibigo byinshi mpuzamahanga byahanuye ko hashobora kubaho ikirere gikabije kandi cyangiza ku isi mu mezi ashize.

Raporo yashyizwe ahagaragara n’umuryango w’ubumenyi bw’ikirere muri Gicurasi, ivuga ko umwaka ushyushye cyane muri iki gihe ari 2015-2016, ubwo isi yahuraga na El Nino amezi 21.

Mu mpera za Kamena, ikinyamakuru Nature cyatangaje ko niba El Nino ikabije, ifite ubushobozi bwo kuzamura ubushyuhe bw’isi kugira ngo yandike cyangwa iri hejuru cyane mu 2024.

Ku ya 4 Nyakanga, Ishami ry'Umuryango w'Abibumbye ry’ikirere ryanzuye ko ikintu cya mbere cya El Nino mu nyanja ya tropique yo mu nyanja ya pasifika mu myaka irindwi, kandi isi yose izaba ifite ikirere cyangiza ndetse n’imiterere y’ikirere byanze bikunze.

Imiti imwe n'imwe izatera ingaruka ku bushyuhe bwinshi bitewe ahanini n'ingingo ebyiri zikurikira:

Ubwa mbere, bifitanye isano nimiterere yibiyobyabwenge

Imiti yica udukoko nudukoko twangiza amazi, imiti yica udukoko twangiza, nka sulfate yumuringa, ifu ya sulfure, ivangwa rya sulfure yamabuye, ikoreshwa mubushyuhe bwinshi, biroroshye cyane kwangiza ibiyobyabwenge mubihingwa, kuko imiterere yimiterere yibigize imiti izahinduka nyuma ya a ubushyuhe runaka, bikaviramo kwangiza ibiyobyabwenge.

Icya kabiri, bifitanye isano no kurwanya ibihingwa

Kurwanya ibiyobyabwenge byamababi yimpu nka Buxus macrophylla birakomeye, kandi kurwanya imiti yibiti bifite ibinure byoroheje, kandi biroroshye kubyangiza ibiyobyabwenge iyo bikoreshejwe mugihe cy'ubushyuhe bwinshi.

1. Abamectin

Abamectin ni umuti wica udukoko wica udukoko, mite na nematode, kandi urashobora gukoreshwa mukurwanya udukoko twangiza udukoko ku bimera bitandukanye. Irashobora kuba mu ngaruka nziza mugihe 20 ℃, ariko ikeneye kwitondera ubushyuhe bwo hejuru, cyane cyane 38 ℃ hejuru yigihe cyo kuyikoresha, bikaba byoroshye kuviramo kwangirika kwibiyobyabwenge, amababi yibihingwa, ibibara, ibintu byo guhagarika imikurire .

2.Pyraclostrobin

Pyraclostrobin ni fungiside yagutse, hamwe ningaruka zo kuvura no kurinda. Hazabaho ibyago byo kwangirika kwibiyobyabwenge nibikoresha cyane.Birashobora gutera ibibabi byibiti.

3.Nitenpyram

Nitenpyram ikoreshwa cyane cyane mukurwanya udukoko twangiza kandi byoroshye kwangiza ibiyobyabwenge mubushyuhe bwinshi, bityo rero tugomba kwirinda. Kandi nibyiza gutera hejuru yubushyuhe buri munsi ya 30 ° C bitazatera gutwika amababi nibindi bintu.

4.Chlorfenapyr

Chlorfenapyr ni umuti wica udukoko twica udukoko, cyane cyane kurwanya udukoko dukuze twa lepidoptera (kungufu, inyenzi za beterave, nibindi). Chlorfenapyr, ubushyuhe bukwiye nka dogere 20-30, ingaruka nziza. Ariko, gukoresha Chlorfenapyr mubushyuhe bwinshi birashobora gutera amababi; Kurenza amababi meza hejuru nayo yangiza ibiyobyabwenge bikomeye.

5. Fluazinam

Fluazinam irashobora gukumira indwara zifata imizi cyane hamwe nudusimba twinshi, kandi irashobora kandi kwirinda udukoko twangiza, nk'igitagangurirwa gitukura cya citrusi (umuntu mukuru, amagi), kandi ingaruka zo kugenzura ni nziza. Fluazinam izongera amahirwe yo kwangirika kwibiyobyabwenge iyo bikoreshejwe mubushyuhe bwinshi, kuko ibikorwa bya Fluazinam ni byinshi cyane. Imiti yubushyuhe bwinshi irashobora kwihutisha guhumeka kwamazi, bihwanye no kongera ubunini bwimiti yamazi.

6.Propargite

Propargite iri muri acariside yuburozi buke, hamwe no guhura nuburozi bwa gastric, hamwe na osmotic. Irashobora gukumira udukoko neza hejuru ya 20 ℃ mugihe imbuto yibimera byoroshye kubyara indwara yizuba hejuru ya 25 ℃.

7.Diafenthiuron

Diafenthiuron ni ubwoko bushya bwica udukoko twa thiourea, acariside, kandi bifite ingaruka runaka zo kwica amagi. Mu gihe cy'ubushyuhe bwo hejuru (hejuru ya 30 ℃) hamwe n'ubushyuhe bwinshi, bizangiza imiti ku ngemwe z'ibihingwa.

Twabibutsa ko ubushyuhe bukwiye bwo gukoresha ibintu byavuzwe haruguru ari ibyerekeranye gusa, kandi ubushyuhe bwihariye nabwo bugomba kugabanywamo ibimera, kandi ubushyuhe bukwiye bwibiti bimwe na bimwe buratandukanye.

Ariko 2,4D, Glyphosate na Chlorpyrifos ni ingirakamaro cyane mu cyi.
