Xa zikhulayo izaqathe, abaninzi bajamelana nokutshatyalaliswa kweengcambu zezityalo i-carrot. Oku kubangela ukuba i-kroti ilahlekelwa yintsikelelo yayo, iba yinto kwaye ayikwazi ukudla. Ngoko ke, kuba abalimi beloli abaye bahlangabezana nale nkathazo, umbuzo ophuthumayo kukuba: yintoni eyoyikisayo inqatyana?
Inkcazo ye-kroti iyabaleka
Inkuku idlula kulezi zigaba zilandelayo zophuhliso:
- I-larva ivela kwiqanda elibekiwe. Ubumnyama, obomvu obukhanyayo, kwaye bunomfanekiso obomvu. Ngaba iphambi libhekise phambili. Ukubonakala kwe-larva kwenzeka ezinsukwini ezingama-5-7 emva kokubeka amaqanda. Bangena kwisityalo esisisiseko kwaye badle malunga nenyanga.
- I-fly fly from the larva. Ubonakaliswe ubude be-4-5 mm. Intloko emdaka, emnyama isisu, ngamaphiko avulekileyo, afumaneke ngasemva ngasemva.
- I-Pupary yinqanaba le-pupa, elisehlabathini lokubhakabhaka ukuya ku-6-25 cm ubunzulu. Ireyenti yepesenti ye-pupae engaphumelelwanga ngempumelelo iphezulu kakhulu.
I-kroti inyuka kwaye ilwa nalo
Ukuze uphumelele ukulwa ne-kroti, kufuneka ukwazi ixesha elibonakalayo. Ukubonakala kwenyuka ekukhanyeni kwenzeka ngexesha apho umhlabathi uchanekile ngokukhawuleza ngo-5-10 cm. Ukushisa kwalo kufanele kufinyelele kuma-16-18 ° C. Emva kweentsuku ezingama-25 ukuya ku-30 emva kokuvela kwamahlumela ezinqabileyo, isigaba sokubonakala kwamagqabi okuqala angama-2 ezayo. Ngokuqhelekileyo oku kwenzeka kwinqanaba lesibini likaMeyi. Leli xesha liqala ukubeka i-karoti amaqanda. Le nkqubo ihlala lonke ihlobo.
Ukulwa ne-fly kukufuna umzamo omkhulu. Oku kubangelwe kubude bexesha lokuhamba ngexesha lezinambuzane zinokubeka amaqanda. Ngoko ke, ukugqithana kwezizukulwana ezahlukeneyo kwenzeka. Iimvumba ezininzi ezakhiwa ekwindla zihlala ngaphakathi kwiingcambu, ezikhokelela ekulimaleni kwazo.
Iimpawu zomonakalo kwizityalo ziyizinambuzane:
- ukubonakala kumagqabantshintshi e-red-violet. Emva koko i-yellowing, i-wilting kunye nokomisa kwenzeka;
- ukubonakala kwe-hillocks ezibomvu kwiingcambu zezityalo, kwaye xa ziqingqiwe, iindinyana ezinokugqithisa ezenziwe ngama-larva.
Iziyobisi ezivela kwi-kroti
Kukho iindlela ezilandelayo zokulwa nendiza:
- khemikhali;
- abantu;
- agrotechnical.
Indlela yeekhemikhali ibandakanya ukusetyenziswa kwezidakamizwa ezahlukahlukeneyo kwi-carrot. Ezi zinambuzane eziqhelekileyo zezi:
- "Arivo";
- "Aktara";
- "Decis";
- "Fitoverm";
- "Vantex".
Unyango kufuneka lwenziwe kusasa okanye kusihlwa ekushiseni okungaphezu kwama-+20 ° C.
Izilwanyana zamanqindi ze-carrot fly ziquka imisebenzi elandelayo:
- ukuhambisa imiqolo phakathi kweeqholi, ezityalwa ngothuli lwegayi okanye ipoward;
- Ukutshiza izityalo nge-tincture yegalikhi okanye i-anyanisi. Le ndlela inokwenzeka kwinqanaba xa i-fly fly iqala ukuhamba. Ukulungiselela i-tincture ithathe i-200 g yeentloko eziqhotyoshelwe kakuhle kwaye ubambelele ngosuku kwi-2 litres zamanzi afudumele. Emva koko ulungiselele isitya kunye neelitha ezili-8 zamanzi, apho kukho isepha yolwelo . I-Tincture ifakwe kuyo;
- i-tincture yeenaliti (200 g yocatshulwa nge-10 ilitha amanzi);
- ukutshiza i-decoction ye-tomato (4 kg yezinto eziluhlaza kwi-10 ilitha zamanzi, ukubilisa kwenzeka ngehafu yure, emva kweeyure ezingama-3 zithathelwa ukunyuswa.) I-decoction ephumela kumlinganiselo we-3 litres ihlanjululwa kwi-10 ilitha amanzi).
Indlela ye-agrotechnical iqulethwe ngamanyathelo okukhusela xa i-karoti iyaphela. Amanyathelo athile afaka:
- ukutshala kwangaphambili kwembewu (ekupheleni kukaMeyi-phakathi kweJuni);
- ukhetho njengendawo yokuhlwayela indawo ephakamileyo yokulala;
- Ukutyala kufuphi ne-anyanisi, iphunga eliloyikekayo kwiinambuzane;
- ukubethelwa kweebhedi, ukuphelisa ukugxilwa kweentukane;
- ukukhutshwa komgquba njengomchumisi;
- ukuthambisa okungaqhelekanga nokulinganiselayo;
- i-peat mulching.
Ukusebenzisa amanyathelo afanelekileyo, unokulwa ngokukhawuleza i-kroti.
