Ganne mein safed makkhi ka ilaj

Patti pehle peeli, phir gulabi-bhoori — aur neeche safed dane kataar mein.

Seedha jawab

Ganne ki safed makkhi patti ke neeche chipak kar ras choosti hai. Nuksan wali patti pehle peeli, phir gulabi-bhoori pad kar kinare se sookhti hai, aur uske neeche safed, chipke hue anda aur bachche kataar mein dikhte hain. Hamla lagbhag hamesha khet ke us hisse se shuru hota hai jahan paani rukta hai. Ilaj: Takila, Atom Bomb ya Shield ka chhidkav, aur khet ki drainage theek karna.

Pehchan

Kaise pehchane

Patti ke neeche safed dane

Patti palat kar dekhiye — safed, chipke hue anda aur bachche kataar mein milte hain.

Patti ka rang badalna

Patti pehle peeli, phir gulabi-bhoori ho kar kinare se sookhne lagti hai.

Chipchipahat aur kaali fungus

Madhu-ras ke kaaran patti par kaali fungus jam jati hai.

Jal-bhrav wale hisse se shuruaat

Khet ke jis hisse mein paani rukta hai ya mitti kharab hai, hamla wahin se shuru hota hai.

Kab aur kahan

Hamla kab tez hota hai

Jal-bhrav aur kharab drainageUmas bhara mausamKamzor aur bhookhi fasalAugust se November

Safed makkhi kamzor fasal ka keet hai. Jahan paani rukta hai ya khaad ki kami hai, wahan yeh baar-baar lautti hai — isliye dawa ke saath khet ki halat sudharna zaroori hai.

Nuksan

Kya nuksan hota hai

Ras choose jane se patti sookhti hai aur ganne mein cheeni banna ghat jata hai. Juice ki quality par asar sabse zyada hota hai — mill recovery girti hai.

Bhaari hamle mein pattiyan waqt se pehle sookh jati hain, ganna patla reh jata hai, aur us khet ka beej agli fasal ke liye kamzor nikalta hai.

Ilaj

Safed makkhi ka upchar

Keet patti ke neeche chipka rehta hai, jahan chhidkav seedha nahi pahunchta. Systemic dawa paudhe ke andar se ras tak pahunchti hai, isliye chhipa hua keet bhi pakad mein aata hai.
