Waa maxay
Baraha Caleenta Alternaria (oo sidoo kale loo yaqaan black spot ama caleen-gubka iyo qudhunka madaxa) waa cudur fangas caadi ah oo kaabashka iyo brassicas-ka kale ah, oo inta badan uu keeno Alternaria brassicicola iyo A. brassicae. Wuxuu keenaa baro wareegsan oo bunni-madow ilaa madow oo leh wareego isku wareegsan oo bartilmaameed u eg iyo wareego jaalle ah, badanaa caleemaha da'da weyn marka hore. Bartamayaashu way dildillaacaan oo dhacaan, taasoo bixisa muuqaal god-god ah. Wuxuu sidoo kale qaadi karaa madaxa, xataa infekshan yar ayaa dalagga suuq-dhicin ka dhigi kara.
Calaamadaha la eegayo
- Marka hore dhibco madow oo yaryar, oo u weynaada baro wareegsan oo bunni-madow ilaa madow
- Wareego isku wareegsan oo bartilmaameed u eg oo baraha ku jira, oo ku wareegsan wareeg jaalle ah
- Caleemaha hoose ee da'da weyn marka hore la saameeyaa; barahu waxay noqon karaan geesaley halka ay xididadu xaddidaan
- Bartamayaasha baraha way dildillaacaan oo dhacaan, taasoo bixisa muuqaal god-god ah
- Baro madow iyo qudhun ayaa ka samaysmi kara madaxa kaabashka, gaar ahaan kaydka
Goorta uu faafo
Heerkul qabow ilaa diiran (qiyaastii 20 ilaa 28 darajo C) oo leh huur sare (ku dhow 87%) iyo muddooyin dheer oo qoyaan caleen oo roob, sayax, ama ceeryaamo ah - badanaa waxay ugu daran tahay xaaladaha huurka badan ee xagaaga iyo dayrta. Fangasku wuxuu ku noolaadaa haraaga dalagga iyo iniinta wuxuuna iniinta gudaheeda ku jiri karaa sannado. Flea beetles-ka ayaa sidoo kale qaadi kara spores-ka.
Daaweynta
Hab-beereedka
Isticmaal iniin nadiif ah oo la xaqiijiyay ama iniin biyo kulul lagu daaweeyay, dooro noocyada u dulqaadan kara, wareeji dalagga oo ka fogow brassicas-ka muddo laba ilaa saddex sano, isticmaal waraabin dhibic iyo kala fogaan ballaadhan si caleemuhu u qalalaan, xakamee cawska iyo flea beetles-ka, oo ka saar haraaga dalagga goosashada kadib.
Xulashooyinka dabiiciga ah
Ka saar oo gub caleemaha qaba iyo haraaga dalagga. Dawooyinka naxaasta iyo dawooyinka noolaha ah ee Bacillus subtilis ayaa ilaaliya caleemaha caafimaadka qaba marka ka-hortag loo mariyo oo la celceliyo 7 ilaa 10 maalmood kasta cimilada huurka badan. Hawo wanaagsan iyo caleemo qalalan ayaa muhiim ah buufin kasta oo aad samayso.
Waxyaabaha firfircoon
- copper hydroxide
- copper oxychloride
- Bacillus subtilis
Xulashooyinka kiimikada
Mari dawooyin ka-hortag ah sida chlorothalonil ama mancozeb ka-hortag ka hor inta cudurku isku dhisin, 7 ilaa 14 maalmood kasta. Dawooyinka leh azoxystrobin, pyraclostrobin, ama difenoconazole ayaa sidoo kale waxtar leh. Isku beddel noocyada shaqaynta si aad u jujuubto caabbinta oo daboolo caleemaha hoose iyo gudaha iyo madaxa.
Waxyaabaha firfircoon
- chlorothalonil
- mancozeb
- azoxystrobin
- pyraclostrobin
- difenoconazole
Badbaadada
Xidho galoofyo, af-daboole, iyo ilaalin isha marka aad buufinayso dawooyinka, oo raac muddada u dhaxaysa buufinta iyo goosashada ka hor goosashada (way kala duwan tahay alaabta). Ilmaha iyo xoolaha ka fogee geedaha la daaweeyay ilaa ay qalalaan, ka fogow in ay u dul-duusho dalagyada cuntada, oo dawooyinka si ammaan ah ugu kaydi meel aan la gaari karin.
Sidii looga hortagi lahaa xilliga soo socda
Ku bilow iniin nadiif ah oo la xaqiijiyay ama biyo kulul lagu daaweeyay, isticmaal noocyada u dulqaadan kara, wareeji dalagga, caleemaha ku qalajiso waraabin dhibic iyo kala fogaan wanaagsan, xakamee cawska iyo flea beetles-ka, oo isla markiiba ka saar haraaga. Dawooyinka ka-hortagga ah ayaa aad uga fiican in la isku dayo in baro isku dhisay la bogsiiyo.
