white lining and spots on zucchini plant
Leaf of my zucchini plant becomes yellowish and also have white linings due to which leafs got destroyed .leafs are also being eaten by some pests as shown in picture 3. Please suggest me some home remedies.
Outside United States vegetable gardening
the yellowing of the leaves is probably caused by downy mildew: turn over the leaves and look for a "fuzzy" mold. It is very hard to control, especially with a home remedy. A mixture of 1 table spoon of baking soda, a teaspoon of horticultural oil mixed into a gallon of water might slow down the spread of the disease (it is not a cure).
Make sure to remove disease leaves and throw them in the trash.
Anything with a chewing mouth part could have caused the holes in the leaves: my guess is cucumber beetles.I do not know of a home remedy and I am not sure what kind of other remedy to suggest since I see you are outside of the US.
Hope this helps a bit.
