Q.Sunflower Leaves Pest
I planted sunflower seeds in feb/mar. The leaves have some yellow/brown spots, i can see some pets growing under. What are there, and how can i remove them? I thought it was fungi and i sprayed a homemade fungicide with baking soda. That did not work, some leaves became black, probably the mix had too much baking soda. Thanks.

If you can see the pest on the underside of the leaves, it is likely aphids. Neem oil will work. You also can wash them off with water.
