Why do the lower leaves of peanuts have spots while the upper leaves are curled?
The preliminary diagnosis is leaf spot disease with a mixed occurrence of scab. It is recommended to spray the foliage with carbendazim, thiophanate-methyl, Aimiao, Score (difenoconazole), Daconil, Amistar, etc. It is best to select two chemicals and use them alternately, applying once every 5-7 days for 2-3 consecutive applications. At the same time, spray the foliage with potassium dihydrogen phosphate.
