Abstract

The present invention relates to a sustained-release biological agent for controlling plant diseases having an excellent controlling effect. In most cases, when pre-existing liquid fertilizers are used by being sprayed directly on grass and crops, the disease-controlling component thereof works transiently on the plant and soil, thus achieving only 1/2-1/3 of the potential effect, while the other 1/2-1/3 of the disease-controlling component is degraded. According to the present invention, the sustained-release biological agent serves to address the above problem, and can maintain the disease-controlling effect of microorganism fermented liquid over a long period of time while releasing the same slowly. Further, as the carrier itself gradually degrades, a small quantity of elements constituting eluted material may serve as nutritive components, allowing the nutritive component of the microorganism fermented liquid to benefit the targeted plant. The sustained-release biological agent is prepared by impregnating a carrier material, selected among diatomaceous earth, rice bran, wheat bran and clay minerals, with a microorganism fermented liquid which is fermented to reach the pH range of 3.0-4.0.

In Korea, 96.5% of synthetic pesticides, 0.5% of biological pesticides, and 3.0% of environment friendly agricultural materials are used as crop protection agents in Korea. However, synthetic pesticides among these crop protection agents are very toxic The manufacturer or user takes great care in handling it, and despite these precautions, there is a risk of lethal damage to the user.

Moreover, not only does it harm the consumer consuming agricultural chemicals contaminated with pesticides, or livestock being raised, but also poses a serious threat to the public health and destroys the ecosystem due to contamination of water quality and soil caused by the spraying of chemical pesticides .

Meanwhile, as international trade agreements such as the FTA are expected to come into effect one after another, in order to secure competitiveness for foreign agricultural products and increase agricultural exports to the US, Europe, and neighboring countries in Asia, The development and dissemination of pest control technology is urgent, and the government is attempting to convert it into an eco-friendly agricultural policy to reduce the use of pesticides and chemical fertilizers.

However, in Korea, the development of natural raw materials and eco-friendly substitutes to replace chemical pesticides and chemical fertilizers has been delayed, and the use of pesticides has not been reduced so much. Therefore, the development of environmentally friendly pesticides as fertilizers come.

As a means of solving these problems, most of the pesticides developed and marketed in Korea have been developed as microbial sustained bioproducts or metabolic products such as BT protein or plant extracts. And it is in the state of being imported as a finished product since imitation product is manufactured by importing main raw material or seed bacterium in a state where the patent right of the relevant strain is not clear.
