Few of my papaya plants showing leaf curl symptoms(curling of new leafs downwards, dark veins). Few plants leaves have bright spots. I am not sure if this is powdery mildew Or leaf blight. Pleas help to identify this disease.
Attached photos of plants with disease. I have observed white fly around plantation on parthenium weeds. I had these removed. There are no pests visible on plant as such.
Request you to suggest pesticide to tackle this issue. I read Dimethoate (0.05%) or Metasystox (0.02%) or Nuvacron (0.05% ) foilar spray for white fly.
Dithane M-45 (0.2%) for leaf blight(assuming it is leaf blight). Please suggest. Thank you.
