In the constituent null spray for agriculture which prevents the runoff

摘要

(A) the water soluble high polymer, (b) the cation chemical compound of polyvalence and/or acidic chemical compound, (c) the agricultural chemical mixing at the time of the agricultural chemical composition and the agricultural chemical application which consist of the agricultural chemical active ingredient the water soluble high polymer which it uses (a), (b) the cation chemical compound of polyvalence and/or the composition for agriculture which consists of acidic chemical compound. The agricultural chemical active ingredient does not run off with the rain as for water solubility the macromolecule of this invention, in order to gel with the cation and acidic chemical compound of polyvalence, the liquid medicine of the agricultural chemical which is spread with the surface of the plant and the pest control object living thing the cation of polyvalence and density of acid becomes high with the process which dryness is done, due to the fact that gelation of the water soluble high polymer happens.
