What is biological control?

From the perspective of application, it can be defined as "using natural enemies to reduce the harm caused by harmful organisms to an acceptable level". From the perspective of science, it can be defined as "a kind of natural ecological capacity, that is, the function of regulating the number of hostile plants and animals". Biological control is a science that studies the theory and practice of using natural enemies to control plant diseases, insect pests and weeds in fields. It is also called the management science of parasites, predators, pathogenic microorganisms and herbivorous species that eat weeds.

How can biological control improve plant growth

1. Improve the underground growth environment

The beneficial bacteria feed was put into the soil to stimulate the reproduction of the beneficial bacteria community. Beneficial inoculants were directly injected to protect the environment around the root system. Seed treatment, from early life to gain a growth advantage.

2. Improve the aboveground growth environment

The application of biostimulant hormone can promote the photosynthetic process and improve the photosynthetic utilization efficiency. It provides synthetic precursors of plant endogenous growth regulators and regulates the balance between plant reproductive growth and vegetative growth in different periods.

3, above and below the mutual promotion.

The good underground growing environment provides the best growing condition for the root system. The well-developed root system and soil microecological balance provide more nutrients and growth promoters for the aboveground growth of plants. Vigorous overground growth provides more energy and nutrients for the activities of underground microorganisms, and stimulates the vitality of microorganisms around the rhizosphere.

Advantages and disadvantages of biological control

1. Abundant natural resources, convenient for local production and application, low production cost and wide application range.

2. Compared with chemical control, it can protect and improve the farmland ecosystem, avoid environmental pollution and is safe for people and livestock.

3, is conducive to delaying the occurrence of insect resistance, in the case of continuous use, some diseases and insects have a continuous and lasting inhibitory effect.

4. Easy to be affected by environmental factors, the prevention and control effect is not stable enough, the use time and technical requirements are strict, and it is not easy to master.

5. Passive in response to sudden diseases and insect pests, slow control effect.

Biological control species

1. Pest control technology, which USES natural beneficial insects and artificially released insects to control the harm of pests, is divided into parasitic natural enemies and predatory natural enemies.

2. Use bacteria and insect control technology to kill pests, bacteria and fungi, etc. with natural microorganisms.

3. The bacteria treatment technology USES antibiotics produced by microorganisms in metabolism to eliminate bacteria.

4, sex pheromone, pigment pest control technology, with the same kind of insect female hormone to kill the male insect pests and pigment killing.

5. Transgenic insect-resistant and disease-resistant technologies: transgenic technologies are used to develop insect-resistant and disease-resistant varieties.

6. Use bacteria to control weeds, and use pathogenic microorganisms to control weeds, such as anthrax bacteria to control weeds in paddy fields.

7. Plant insecticidal and bactericidal technologies:

(1) photoactivator is the use of plant secondary substances in the light of the toxic effect of pests, viruses.

Inchetin is a kind of highly oxidized citric acid, which is separated from the active material, with insecticidal components.

 Now, we will enter the field of biological control together with the world leader in biological control and biological pollination, Dutch company colbert, to focus on the professional, cooperate with nature, provide users with natural and safe nutrition solutions, improve crop health, enhance crop stress resistance, and finally achieve high yield and high quality.
