1. Claim 1: an ingredient, including an aquatic pesticide and a treated surface calcium carbonate (wherein the aquatic pesticide contains ethylene oxide) and a treated surface calcium carbonate, is a reaction product of naturally ground calcium carbonate or precipitated calcium carbonate, which contains carbon dioxide, and Or more ion donors h83323 or 8314；,where carbon dioxide is formed in situ by treatment with H₃O⁺ ion donors and / or is supplied by an external source. Claim 4: The composition of any of the preceding claims, wherein the aquatic pesticide is selected from the group consisting of rotenone, a plant extract containing rotenone, a formulation comprising rotenone, and mixtures thereof, preferably the aquatic pesticide is selected from group consisting of rotenone, cube resin,Deris resin, CFT ligumine, Tifa Chem fish, prentox prenfish, cuberol, fish tox, noxfire, roacide, sinid, tox-r, cure flea dust, derrin, cenol garden dust, chem mite, cibe extract, green cross warble powder and their mixtures. 6. Claim 6: the composition of any of the above claims, i.e. the treated surface calcium carbonate is obtained by a procedure including the following steps: (a) suspension treatment of naturally ground calcium carbonate or precipitated calcium carbonate,b) adding at least one acid that has a pKₐ value of 0 or less at 20 ° C or that has a pKₐ value between 0 and 2.5 at 20 ° C to the suspension of step a)；And (c) process (a) suspend the transition to (b) carbon dioxide before, during or after. Claim 11: the use of an ingredient for the control of aquatic pests, comprising an aquatic pesticide and treated calcium carbonate, And the surface treated calcium carbonate is the reaction product of natural ground calcium carbonate or carbon dioxide precipitated calcium carbonate and one or more ion donors h8323； orAmong them, carbon dioxide is formed through in-situ treatment by ion donor h832383, or by external sources.Reivindicación 1: Una composición que comprende un
