I prepared seedlings of tomato plants. Now from around a week there are snake like design in leafs. There is some sort of bug inside leaf which is eating. What should i do for it. Can/should i use some pesticide on such small plants?
I live in Jaipur, India. Current temperature ranging between 20-30 degree C.
Update : soil is a mix of 50% coco peat and 50% of vermi compost. Watering alternate day. They are on roof outside, partial sun. From where these larvas are coming ? Flies? If i spray pesticide wont that help in keeping flies away ?
