I have started to put new plants on my roof top. I stay in Chennai. I see that on my hibiscus plants, there are some small insects that are in white color. They have sticky substance. After reading few blogs, I understand they might be Aphids. . I tried by spraying turmeric powder, and also used the powder given in the nursery when asked for. I also used Red chilli powder (read somewhere). Still aphids are there. Can someone please help me how to get rid off those insects
Thanks A lot.
