Kapas mein dahiya ka ilaj

Patti ke neeche raakh jaisi safed parat — upar halka konedar peela dhabba.

Seedha jawab

Dahiya ek fungus rog hai. Patti ke neeche safed-slate rang ki raakh jaisi parat jamti hai, aur usi jagah upar se halka konedar peela dhabba dikhta hai. Bhaari hamle mein patte samay se pehle jhad jate hain. Ilaj: Samurai aur Azoto Prime.

Pehchan

Kaise pehchane

Patti ke neeche raakh jaisi parat

Patta palatne par safed-slate rang ki powder jaisi parat dikhti hai, jo ungli se hat jati hai.

Upar konedar peela dhabba

Usi jagah patte ke upar halka peela, nas se ghira konedar dhabba banta hai.

Neeche ke patte pehle

Rog sabse pehle neeche ke patton par aata hai aur dheere-dheere upar chadhta hai.

Patta jhadna

Bhaari hamle mein patte peele pad kar samay se pehle jhad jate hain, aur paudha nanga dikhta hai.

Kab aur kahan

Hamla kab tez hota hai

Thandi raat aur osBarish ke baad ki namiFasal ka baad ka hissaGhana khet

Dahiya ko thandi, os wali raat aur nam mausam pasand hai, isliye woh fasal ke baad ke hisse mein aata hai — theek us samay jab boll bhar rahe hote hain. Hafte mein ek baar neeche ke patte palat kar dekhna hi samay par pakadne ka tarika hai.

Nuksan

Kya nuksan hota hai

Parat patte ki satah dhak deti hai, isliye patta dhoop se bhojan nahi bana pata.

Boll bharne ke samay patta jhad jaye to boll chhote reh jate hain aur rui halki nikalti hai.

Ilaj

Dahiya ka upchar

Chhidkav ka sahi samay wahi hai jab rog neeche ke patton par hi hai — upar tak chadhne ke baad nuksan ho chuka hota hai. Sulphur wali chemistry is tarah ke mildew par khaas achhi kaam karti hai.

Dhyan dein: Rog neeche se upar chadhta hai, isliye chhidkav neeche ke patton par pahunchna zaroori hai — sirf upar se chhidkav kaam nahi karega. Jhada hua patta wapas nahi aata; dawa bache hue patton ko bachati hai. Khet ghana na rakhein aur nitrogen zaroorat se zyada na dein.
