Ganne mein laal sadan ka ilaj
Ganna cheeriye. Andar laal rang aur khatti, sirke jaisi badbu — bas, pehchan ho gayi.
Laal sadan ek fungus rog hai, aur yeh saaf jaan lena zaroori hai: khade ganne mein iska koi ilaj nahi hai. Jo ganna sankramit ho gaya, woh kisi dawa se theek nahi hota. Poora prabandhan bachav ka hai — swasth beej, sett upchar, sankramit jhund ko turant nikalna, aur sanvedansheel variety badalna. Sett upchar ke liye Samurai ya Azoto Prime jaisi fungicide istemal hoti hai; yeh bachav hai, ilaj nahi.
Kaise pehchane
Teesri-chauthi patti peeli
Beech ki pattiyan bahar se andar ki taraf peeli pad kar sookhne lagti hain.
Andar laal rang
Ganna lambai mein cheer kar dekhiye — andar laal rang, beech-beech mein safed dhabbe (cross bands).
Sirke jaisi khatti badbu
Cheere hue ganne se khatti, sirke jaisi badbu aati hai — yeh laal sadan ki sabse pakki pehchan hai.
Khokhla aur halka ganna
Ganna andar se khokhla ho jata hai, wazan girta hai, aur thapthapane par khokhli aawaz aati hai.
Hamla kab tez hota hai
Rog sabse zyada beej ke saath failta hai, aur khet mein paani ke behav se ek jhund se doosre tak jata hai. Bedhak ya deemak se ghayal ganne mein fungus aur aasani se ghusta hai.
Kya nuksan hota hai
Sankramit ganne ki cheeni khatm ho jati hai — mill mein aisa ganna recovery ghatata hai aur kabhi reject bhi hota hai. Poore jhund sookh jate hain.
Sabse bada nuksan aage ka hai: us khet ka ganna beej banane layak nahi rehta. Sankramit beej agle saal naye khet mein rog le jata hai, aur ek saal ki galti kai saal chalti hai.
Bachav aur upchar
Yahan dawa ka kaam sirf bachav hai — beej ko saaf karna aur naye sankraman ko rokna. Khade sankramit ganne par kharch karna bekar hai; usko nikalna hi sahi kadam hai.
Sabse zaroori baat: laal sadan mein dawa se khada ganna nahi bachta. Sankramit khet se beej kabhi na lein. Sankramit jhund dikhe to use jad se nikaal kar khet se bahar nasht karein, aur us jagah chuna ya bleaching powder daalein. Khet mein paani rukne na dein, aur sanvedansheel variety ki jagah pratirodhi variety lagayein. Variety ke chunav par apne ganna vikas adhikari ya humse baat karein.
