Dhan mein aavaran jhulsa (sheath blight) ka ilaj

Paani ki satah ke paas khol par saanp ki khal jaisa dhabba — aur paudha jhuk kar gir jaye.

Seedha jawab

Aavaran jhulsa ek fungus rog hai jo patti ke khol par, paani ki satah ke thoda upar se shuru hota hai. Dhabba beech se safed-bhoora aur kinare se gehra bhoora hota hai, saanp ki khal jaisa. Dhabbe upar chadhte hain, tana kamzor pad jata hai aur paudha jhuk kar gir jata hai. Yeh jhulsa (BLB) se alag rog hai — BLB bacteria ka hai aur patti ke kinare se shuru hota hai. Ilaj: Samurai aur Azoto Prime.

Pehchan

Kaise pehchane

Saanp ki khal jaisa dhabba

Patti ke khol par beech se safed-bhoora, kinare se gehra bhoora dhabba — saanp ki khal jaisi banawat.

Paani ki satah se shuru

Hamla neeche se, paani ki satah ke thoda upar se shuru hota hai aur dheere-dheere upar chadhta hai.

Sarson jaise daane

Rog wale khol par sarson ke daane jaise chhote bhoore gutt (sclerotia) dikhte hain, jo haath se gir jate hain.

Paudhe ka girna

Tana kamzor pad jane par paudha jhuk kar gir jata hai, khaas kar baali bharne ke samay.

Kab aur kahan

Rog kab badhta hai

Ghani fasal aur band hawaZaroorat se zyada nitrogenLagatar khada paaniBarish ke baad ka ummas

Rog kalle nikalne ke baad, jab fasal ghani ho jati hai, tez badhta hai. Jaanch ke liye paudhe ke neeche jhuk kar paani ki satah ke paas ka khol dekhna zaroori hai — upar se khet theek dikhta hai.

Nuksan

Kya nuksan hota hai

Rog wala khol khana bana kar daane tak nahi pahuncha pata, isliye daana halka aur pichka reh jata hai.

Gira hua paudha na theek se pakta hai na aasani se kaatne mein aata hai. Bhare khet mein girai se katai ka kharcha bhi badh jata hai.

Ilaj

Aavaran jhulsa ka upchar

Fungicide bachav ka kaam karta hai. Chhidkav neeche, paani ki satah ke paas ke khol tak pahunchna chahiye — sirf upar ki patti bhigane se fayda nahi hota. Nozzle niche karke, tane ke aas-paas dawa dein.

Dhyan dein: jo paudha gir chuka hai woh kisi dawa se wapas khada nahi hota — chhidkav baaki fasal ko bachata hai. Do cheezein rog ko sabse zyada badhati hain: ghani ropai aur zyada nitrogen. Paudhe ke beech jagah rakhein, khet ka paani beech-beech mein sukhayein, aur nitrogen thoda-thoda baant kar dein. Fungus ke gutt mitti mein bache rehte hain, isliye khet ka parali aur thoothi hataana agle saal kaam aata hai.
