The invention discloses a process for preparing pesticides with growth regulation functions. The process has the advantages that two effective components in pesticides obtained at a step (1) include dichlorvos and dimethoate and are mixed with each other according to a volume ratio of 3:4, and accordingly the two pesticides are wide in service range and are broad in applicability after the two pesticides are mixed with each other; stirring and dispersing modes in the step (1) include arranging mixed solution in a sealed container and stirring the mixed solution on a magnetic stirrer for 20 min, and the pesticides can be quickly, easily and conveniently mixed with each other in the stirring and dispersing modes; suspending agents used in a step (2) are sustained-release pesticide suspending agents with micro-capsule components, and accordingly the pesticide properties of the pesticides with the growth regulation functions can be prolonged by additional sustained-release functions; mixed acid solution used in a step (4) is solution with fulvic acid, salicylic acid, citric acid and sodium bicarbonate which are mixed with one another according to a proportion of 1:1:3:1, and the performance of growth regulators can be effectively stabilized by the mixed acid solution.
