Bio-herbicides are the perfect alternative, helping to reduce dependence on chemical herbicides, which are harmful to humans as well as other plants and animals. Let’s learn about herbicides Best biology.
What is a bio-herbicide?
Bio-herbicides are a sustainable, low-cost and environmentally friendly method of weed control. This drug is mainly composed of microorganisms that are effective in killing weeds (mainly fungi).
Each type of fungus is usually effective in controlling specific weeds. For example, the fungus Phytophthora Palmivora has the ability to prevent milkweed from growing in citrus orchards. Water hyacinth growth was controlled by the fungi Cercospora Rodmanii and Alternaria Eichhorniae.
The fungus Puccinia Chondrilla is used to control the growth of a weed called Chondrilla Juncea.
The first bio-herbicide used in the world was a fungicide that was introduced in 1981.
Evaluate the advantages and disadvantages of bio-herbicides
The need to control weeds with biological drugs is increasing because of the great benefits that this solution brings. However, bio-herbicides still have some disadvantages that need to be optimized.
Advantages of bio-herbicide
- Effective in eradicating target weeds
- Does not affect plants, animals and non-target humans
- No residue accumulation in the environment due to rapid decomposition
- Effective in killing resistant weeds
Disadvantages of bio-herbicide
Bio-herbicides are generally slower to be effective and require more storage than chemical herbicides. In addition, the effectiveness of this drug is also greatly affected by environmental conditions (temperature, rainwater, …).
However, before the great benefits, we can completely accept these disadvantages.
