I did read through another question on these, but our worm was not described. This is our first attempt at growing broccoli and really disappointed. The worm was white and had fuzz all around it but I don't think it was part of the worm. It was inside in the middle of the stem and up toward the flowers. Since we cut the stem from the plant, I am assuming it starts at the bottom and works its way up. The whole middle of the stem was yucky with what looked like chewed up plant and fuzz. Since we have several other plants, what can we do to prevent these or even kill them? The plants were beautiful and green and very hardy looking so we really had no idea there was any type of infestation. Thank you.
