Reference for Bava Batra 36:6

ורבנן דבורים לחרדל לא מזקי ליה אי בבינתא לא משכחא ליה אי בטרפא הדר פארי

— The truth is that R. Jose also holds that it is incumbent on the one who inflicts the damage to remove himself, and he argued with the Rabbis as follows: I grant you are right in the case of the flax water and the vegetables, because the former harms the latter but not vice versa, but the case is different with bees and mustard, because both are harmful to one another. What have the Rabbis to say to this? — That bees do no harm to mustard; the grains they cannot find, and, if they eat the leaves, they grow again.
