Mankhwala ophera bowa

Mafangayi ndi mtundu wa mankhwala ophera tizilombo omwe amagwiritsidwa ntchito poletsa matenda a zomera omwe amayamba chifukwa cha tizilombo toyambitsa matenda osiyanasiyana. Mafangayi amagawidwa m'magulu a fungicides osapangidwa ndi organic ndi organic fungicides kutengera kapangidwe kake ka mankhwala. Pali mitundu itatu ya fungicides osapangidwa ndi organic: sulfure fungicides, copper fungicides, ndi mercury fungicides; Mafangayi achilengedwe amatha kugawidwa m'magulu a organic sulfure (monga mancozeb), trichloromethyl sulfide (monga captan), benzene yosinthidwa (monga Chlorothalonil), pyrrole (monga seed dressing), organic phosphorus (monga aluminium ethophosphate), Benzimidazole (monga Carbendazim), triazole (monga triadimefon, triadimenol), phenylamide (monga metalaxyl), ndi zina zotero.

Malinga ndi zinthu zopewera ndi kuchiritsa, zitha kugawidwa m'magulu awiri: Fungicide, mabakiteriya, opha mavairasi, ndi zina zotero. Malinga ndi Njira Yogwirira Ntchito, zitha kugawidwa m'magulu awiri: zoteteza ku fungicides, zopumira, ndi zina zotero. Malinga ndi komwe zinthu zopangira zimayambira, zitha kugawidwa m'magulu awiri: zopumira, zopumira, ndi zina zotero (monga jinggangmycin, agricultural antibiotic 120), zopumira, ndi zomera, ndi Defensin. Malinga ndi njira yophera tizilombo, nthawi zambiri imatha kugawidwa m'magulu awiri: zopumira ndi zopumira. Mwachitsanzo, chlorine, Sodium hypochlorite, bromine, ozone ndi chloramine ndi zopumira, ndi zina zotero.

1. Malangizo Ogwiritsira Ntchito Mafangayi Mukasankha Mafangayi, ndikofunikira kumvetsetsa makhalidwe awo. Pali mitundu iwiri ya mafangayi, imodzi ndi yoteteza, yomwe imagwiritsidwa ntchito popewa matenda a zomera, monga madzi osakaniza a Bordeaux, mancozeb, Carbendazim, ndi zina zotero; Mtundu wina ndi mankhwala ochiritsira, omwe amagwiritsidwa ntchito pambuyo poti matenda a zomera ayamba kupha kapena kuletsa mabakiteriya opatsirana omwe amalowa m'thupi la zomera. Mankhwala ochiritsira amakhala ndi zotsatira zabwino kumayambiriro kwa matenda, monga mankhwala ophera mafangayi monga Kangkuning ndi Baozhida.

2. Mankhwala ophera bowa ayenera kupopedwa nthawi isanakwane 9 koloko m'mawa kapena itatha 4 koloko masana kuti apewe kugwiritsidwa ntchito padzuwa lotentha. Ngati apopedwa padzuwa lotentha, mankhwala ophera bowa amatha kuwola ndi kusungunuka, zomwe sizingathandize kuti mbewu zilowe m'nthaka.

3. Mankhwala ophera bowa sangasakanizidwe ndi mankhwala ophera bowa a alkaline. Musawonjezere kapena kuchepetsa kuchuluka kwa mankhwala ophera bowa omwe agwiritsidwa ntchito, ndipo muwagwiritse ntchito ngati pakufunika kutero.

4. Mankhwala ophera fungicide nthawi zambiri amakhala ufa, emulsions, ndi suspensions, ndipo ayenera kuchepetsedwa kaye musanagwiritse ntchito. Mukasungunula, choyamba onjezerani mankhwala, kenako onjezerani madzi, kenako sakanizani ndi ndodo. Mukasakaniza ndi mankhwala ena ophera fungicide, mankhwala ophera fungicide ayeneranso kuchepetsedwa kaye kenako n’kusakaniza ndi mankhwala ena ophera fungicide.

5. Pakati pa kugwiritsa ntchito mankhwala ophera fungicide ndi masiku 7-10. Kwa mankhwala omwe ali ndi vuto lolimba komanso osayamwa bwino mkati, ayenera kupopedwanso ngati mvula itagwa mkati mwa maola atatu mutapopedwa.
