Q.Dill Weed Disease
Leaves on my dill weed plants are covered by some white residue which doesn’t resemble mealybugs. It looks more of fungus nature. At that is what I think. I also noticed small white spots on stems as well lately. I have already tried different soaps and it didn’t work. It is only present on dill plants and not on neighboring parsley, cilantro or chives. Please help. I have a lot of cucumbers and no dill.

Is it powdery in nature? If so, your plants have powdery mildew, which is a fungal issue and can be treated with neem oil. It is both an effective pesticide and fungicide, so it should take care of the issue regardless of whether or not it's a fungal problem or brought about by pests. Here is some additional information that will help determine if this is your problem and how to fix it: https://www.gardeningknowhow.com/plant-problems/disease/get-the-cure-for-powdery-mildew.htm, https://www.gardeningknowhow.com/problems/pests/neem-oil-uses.htm
