What is the Biocontrol Agents
In agricultural production, growers will face many issues like soil-borne diseases( powdery mildew, rhizoctonia solani, fusarium wilt), annoying pests(grasshopper, thrips, armyworm), weeds. Today’s developed chemical formulations can overcome most of the problems, but at the same time cause pollution to the environment, which is not conducive to the sustainable development of natural ecology.
In the evolution of biology, the principle of natural selection has always existed. The use of competition between organisms to solve various problems encountered in agricultural production meets the demands of organic agriculture.
Biocontrol agents are the bioproduct line that focuses on controlling the diseases and pests. With the research of biological science, it has developed many species: Trichoderma spp, Bacillus. spp, Beauveria bassiana, Paecilomyces lilacinus, Penicillium bilaii, etc.
Biocontrol Agent’s Mode of Action
There are generally three control strategies:
- Introduce natural enemies of pests to achieve control.
- Apply large numbers of natural enemies to quickly control harmful groups.
- Strengthen protection and take measures to repair itself to resist invasion.
Biocontrol Agents and Chemical Control
Farmers are accustomed to using various chemical pesticides. At the same time, chemical pesticides are inexpensive and easy to use. Farmers rarely spend time and experience trying methods to control pests without chemical pesticides. In conventional agriculture, the strategy for pest control is to focus more on prevention than on prevention, emphasizing the right medicine, rational drug use, and focusing on the relationship between crops and pests.
The biocontrol agent is based on prevention and control. Under the conditions of natural growth, the crops rely on the natural resistance of the crops to the adverse external environment to improve their ability to resist diseases and insects. What humans can do is taking safe natural measures to control rather than eliminate pests.
Biocontrol agents are a wide range from microbes to animals and plants, creating a pollution-free reaction to the environment, it can be used in various crop cultivator.( bean, rice, tomato, potato, maize, fruits, and flowers)
