Waa maxay
Target spot waa cudur fangas ah oo halis ah oo uu keeno Corynespora cassiicola. Wuxuu inta badan ku dhacaa meelaha kulaylaha iyo qoyaanka badan. Wuxuu waxyeelleeyaa caleemaha iyo midhaha tamaandhada, wuxuuna keenaa dhibco caleemaha ah, caleemaha oo dhaca iyo nabarro midhaha ka soo baxa oo sababa qudhun. Fangaskani wuxuu kaloo ku dhici karaa dalagyo kale sida khiyaarka iyo babaayga.
Calaamadaha la eegayo
- Dhibco yaryar oo caleemaha ah oo bunni khafiif ah leh bartamaha iyo gees ka madow.
- Dhibcaha oo mararka qaar yeesha gooboyin isku xiga
- Cudurku badanaa wuxuu ka bilaabmaa gudaha geedka kadibna kor ayuu u fidaa marka qoyaanku badan yahay.
- Caleemaha oo si degdeg ah u engega una dhacaya.
- Miraha oo yeesha nabaro bunni ah oo godan, mararka qaarna dildilaac leh
Goorta uu faafo
Cimilada diiran (21–27°C) ee qoyaanka badan leh, roobka ama waraabinta caleemaha dushooda. Beeraha ciriiriga ah ee hawadu ku yar tahay waxay kordhiyaan cudurka. Fangasku wuxuu ku faafa dabaysha iyo biyaha roobka, babaayga u dhowna wuxuu noqon karaa meelaha uu kasoo bilaabmo.
Daaweynta
Hab-beereedka
Samee dalagg gedis 2–3 sano. Ha ku beerin tamaandho cusub meel ku dhow dalag hore oo cudur qaba ama babaay. Taageer oo jar dhirta si hawadu u socoto, ka saar caleemaha hoose, xakamee haramaha, kana fogow waraabinta caleemaha. Nadiifi oo baabi’i haraaga dalagga kadib goosashada.
Xulashooyinka dabiiciga ah
Ka saar oo baabi’i caleemaha hoose ee cudurka qaba iyo hadhaaga dhirta. Isticmaal copper fungicides ama daawooyin dabiici ah oo ku salaysan Bacillus subtilis iyo Trichoderma si loo ilaaliyo caleemaha caafimaadka qaba. Hagaajinta hawo socodka iyo in caleemuhu qalalaan waa muhiim.
Waxyaabaha firfircoon
- copper hydroxide
- Bacillus subtilis
- Trichoderma harzianum
Xulashooyinka kiimikada
Isticmaal fungicides sida chlorothalonil, azoxystrobin, pyraclostrobin, boscalid iyo mancozeb. Ku celi 7–14 maalmood kasta, gaar ahaan marka roobka iyo qoyaanku badan yihiin. Beddel noocyada daawooyinka si looga hortago iska caabbinta fangaska.
Waxyaabaha firfircoon
- chlorothalonil
- azoxystrobin
- pyraclostrobin
- boscalid
- mancozeb
- acibenzolar-S-methyl
Badbaadada
Xidho galoofisyo, mask iyo murayadaha indhaha markaad buufinayso fungicides. Raac muddada sugitaanka ee daawada ka hor goosashada. Carruurta iyo xoolaha ka fogee dhirta la daweeyay ilaa ay qalasho, kana ilaali buufinta inay gaarto dalagyada kale. Kiimikooyinka ku kaydi meel ammaan ah.
Sidii looga hortagi lahaa xilliga soo socda
Isticmaal siidh nadiif ah iyo geedo caafimaad qaba. Kala fogee dhirta si hawo fiican u hesho, waraabi salka geedka, kana fogee beeraha cusub dalagyada hore iyo babaayga. Si joogto ah u baadh gudaha geedka, sababtoo ah cudurku halkaas ayuu inta badan ka bilaabmaa.
