PURPOSE: To obtain a composition having suppressed crystallization by blending a hydrophobic agricultural chemical of melting point approximately at normal temperature with poly(3)oxypropylenedibenzyl cresyl ether or poly(4) oxypropylenebisphenol A, etc. n CONSTITUTION: A hydrophobic agricultural chemical having a melting point approximately at 0-50°C is blended with one or more selected from compounds shown by formula I and formula II (R 1 is ethylene, propylene or butylene; R 2 is H, benzyl, etc.; R 3 is H, alkyl or phenyl; R 4 is 1-5C alkylene; m is 1-10; n is 1-3) and adducts of resin acid or disproportionated resin acid with ethylene oxide, propylene oxide or butylene oxide under heating at 50-60°C in a molten state to give the title composition. The composition can be stably maintained in an emulsified state in a temperature range of -5-50°C and has tendency to increase absorption and transfer to weeds and crops. n COPYRIGHT: (C)1990,JPO&Japio |
