What are herbicides?

  • Herbicides are a type of biological insecticide that effectively kills pests, insects, on crops. It active ingredients obtained from nature, mainly extracted from herbs and some plants with essential oils. Herbs that are poisonous, spicy, hot, etc. will have the effect of poisoning pests, repelling insects and animals that destroy crops and plants.

  • Currently, there are many studies using herbicides. In particular, the extraction of natural compounds from plants with high toxicity to pests is the most interest. In this direction, herbicides often kill pests effectively reduce the resistance of pests, have a fast resolution time; thus do not pollute the environment, are safe for human health.

Advantages of Herbicides:
  • Less toxic than for the people, in animals and no effects to the species have utility as birds, fish and the natural enemy.
  • High selectivity and biological potency (low dose).
  • Biodegradation is fast, leaving little residue in the environment and agricultural products, so herbicides is very friendly to the environment.

National Center for Technological Progress – HCM Branch research and deploying highly effective biological plant protection contents; emphasizing biological measures. With the purpose of creating a pesticide derived from herbs against insects that damage crops, without affecting human health during use. It create clean agricultural products to ensure health and sustainable ecological environment.

Uses of biological Herbicides:
  • Herbicides are researched products from herbs and some plants with essential oils; soluble in water, and effective in preventing and destroying pests on most crops and effective for a long time.
  • Herbicides is absorbed into the sap of the tree, changing the enzyme activity; changing the transpiration and changing the composition of the water in the cells and the sap, affecting the hormones of the insects and pests.
  • This product has the effect of repelling and treating some types of pests such as aphids, worms at low density. In herbs containing acidic content, it affects parts such as eyes and skin of plant pests and can destroy them.

How to use herbicides effectively?

In order to use herbicides with high efficiency, farmers need to know how to use them and the appropriate dosage.

  • Choose herbicides suitable for pests and types of pests.
  • Prepare the drug with the concentration recommended by the manufacturer to avoid using too much, causing harm to natural enemies.
  • Should spray herbicides every 7-10 days to prevent pests.
  • When pests appear, spraying should be done at the larval stage to avoid pests damage to crops and bring high efficiency.
  • When an epidemic has broken out, special drugs or other products with faster and stronger effects should be used.
  • Although herbicides are not too toxic to human health, it is still necessary to have an quarantine period of 5-7 days; to ensure that there are no pesticides left on agricultural products.
