I-tomato blight yakuqala iyisifo esivamile sikatamatisi, esingase senzeke phakathi nezigaba zamuva ze-tomato yisithombo, ngokuvamile esimweni somswakama ophezulu kanye nokumelana nezifo zezitshalo ezibuthakathaka, kungalimaza amaqabunga, iziqu kanye nezithelo zikatamatisi emva kokuvela, futhi kuholele ngisho nasezitshalweni ezingathi sína zikatamatisi.

1, utamatisi okulimaza zakuqala kungenzeka esigabeni yisithombo, ngakho kumelwe senze umsebenzi omuhle wokuvimbela kusengaphambili.

I-2, lapho isitshalo sithinteka ebunzimeni, iqabunga elijwayelekile lizobonisa ukuphuzi, amabala amnyama, ukugoqa kweqabunga nezinye izimpawu, kulokhu, ukumelana nezifo zikatamatisi kwehle, amagciwane esifo sokuqala athatha ithuba lokuthelela umonakalo.

3, utamatisi ekuqaleni kwesifo amabala amabala ansundu, ngezinye izikhathi kuyoba ne-halo ephuzi ezungeze indawo, ukuhlangana kwezifo kusobala, ukuma kwendawo ngokuvamile kuyindilinga.

4, i-tomato blight yasekuqaleni ngokuvamile iqala emaqabunga aphansi, bese kancane kancane isakazeka phezulu, ikakhulukazi amaqabunga aphansi awaqedi ngesikhathi (ukusebenza kwangempela kunengqondo ngokuvumelana nesimo, ngokuvamile kushiya cishe amaqabunga ama-2 endlebeni yezithelo) isakhiwo kulula ukwenzeka, ngoba kuleli cala izokwakha indawo encane evaliwe umswakama ophezulu, utamatisi okulimaza zakuqala kanye nezinye izifo kulula kakhulu ukwenzeka.

5, utamatisi okulimaza zakuqala kwenzeka maphakathi kanye nezigaba sekwephuzile amaqabunga uzobe exutshwe nezikhathi ezahlukene amachashaza isifo, lezi amabala ziyophuka esimweni esomile.

I-6, amabala okulimaza utamatisi okuqala phakathi nesigaba sekwephuzile sephethini yesondo livela, iphethini yesondo izovela amachashazi amancane amnyama, lawa machashazi amancane amnyama amagciwane okuqala okulimaza i-conidium, equkethe i-conidium, i-conidium ingasakazwa ngomoya, amanzi, izinambuzane neminye imithombo yezindaba ezicutshini ezinempilo iyaqhubeka nokulimaza.

7, ngemva kokuvela kwesifo sikatamatisi zakuqala, uma isilawuli singafika ngesikhathi noma indlela yokuvimbela ayilungile, indawo yesifo izokhula bese ijoyina enkulu.

8, exhunywe ucezu okulimaza zakuqala, utamatisi ushiya ngokuyisisekelo elahlekile umsebenzi.

9, Ukufa kweqabunga okubangelwa ukubola kwasekuqaleni kungabonakala esithombeni.

10.Ukubola kukatamatisi ekuqaleni kuholela ekudonseni kwezithombo.

Ukuvimbela kanye nokwelashwa okulimaza zakuqala of utamatisi

Ukubola kokuqala kukatamatisi kungalawulwa ngezindlela ezilandelayo:

1.Ukubulala amagciwane kwembewu nomhlabathiNgaphambi kokushintsha isitshalo, izinsalela zikatamatisi kufanele zihlanzwe, futhi inhlabathi kufanele ibulawe amagciwane.Imbewu katamatisi nayo idinga ukubulawa amagciwane ngokucwiliswa kwesobho elifudumele kanye nokucwiliswa kwemithi.

2, gwema insimu evaliwe umswakama ophezuluSusa amahlamvu amadala engxenyeni engezansi katamatisi ngesikhathi nangendlela enengqondo ukuze uqinisekise ukomisa okulinganiselwe kwensimu futhi udale izimo ezingafanele ukuvela kokubola kokuqala.

3, ukuthuthukisa ukumelana nezifo zikatamatisiNgokwezimpawu zesidingo sikatamatisi sikamanyolo namanzi, isithasiselo esinengqondo sikamanyolo namanzi singaqinisekisa ukukhula okunempilo kukatamatisi futhi sithuthukise ikhono likatamatisi lokumelana nokubola kwangaphambi kwesikhathi.Ngaphezu kwalokho, ukusetshenziswa kwezitshalo zokuzivikela komzimba ezifana ne-protein yokuvula ye-spora ye-chain enhle kakhulu kungenza kusebenze amasosha omzimba katamatisi, bese kuthuthukisa ikhono likatamatisi lokumelana nokubola kwangaphambi kwesikhathi kusuka ngaphakathi ngaphandle.

4, ukukhethwa okunembile kwama-ejenti okuvikela nokulawulaEkuqaleni kwesifo kusenesikhathi, kukhethwa ama-fungicides endabuko ezindawo eziningi njenge-chlorothalonil, i-mancozeb kanye namalungiselelo ethusi.Ama-fungicides e-Methylic acrylate afana ne-pyrimidon ne-pyrimidon angasetshenziswa.Phakathi nokuqala kwesifo, kuyadingeka ukususa izicubu ezinesifo kuqala, bese usebenzisa ama-fungicides endabuko ezindawo eziningi + Pyrimidon/pyrimidon + phenacetocyclozole/pentazolol ukuze kuvinjelwe nokulawula (amalungiselelo ayinhlanganisela afana ne-benzotrimethuron, i-pentazole, i-fluorobacterium oximide, njll.), ngesikhawu esingangezinsuku ezi-4 Qhubeka nokusebenzisa izikhathi ezingaphezu kwezi-2, lapho isifo silawulwa ekuphathweni okujwayelekile, ukuqinisekisa ukuthi isifutho siyafana futhi siyacabangela.
