PURPOSE: A process of preparing agricultural chemicals by absorbing high concentration agricultural chemical components in a porous carrier is provided. Whereby, the composition has a sustained release effect for about 30 to 40 days while showing excellent exterminating effect. CONSTITUTION: About 1 to 100g active ingredients of agricultural chemicals is dissolved in 100ml solvents to produce active agricultural chemicals. And 0.5 to 2.0kg porous carrier is then added to 100ml active agricultural chemicals, uniformly mixed and dried to produce an active ingredients-absorbed carrier. A suspension containing 0.5 to 15g polysaccharides is added to 1kg active ingredient-absorbed carrier and dried. The porous carrier is one or two or more mixtures selected from the group consisting of zeolite, pearlite, vermiculite, diatomaceous earth, ceramic and active carbon. |
