One farmer brought cabbage covered in slime.Nothing can be done to save his cabbages this year, but Daniel Lyazi's advice may save the next season's crop."So he's telling me there's a small caterpillar which eats the cabbages starting from the youngest leaf.He's told me that the whole garden has been attacked and affected by this caterpillar.
