Urtica dioica
A Natural and Effective Biocontrol Agent
Urtica dioica, commonly known as stinging nettle, is a perennial herb that grows in temperate regions of the world. It has been used for centuries as a food, medicine, fertilizer, textile, and cosmetic ingredient.
But did you know that it can also be used as a biocontrol agent against various plant pests and diseases?
How does urtica dioica act as a biocontrol agent?
Urtica dioica has several mechanisms of action that can help protect plants from pests and diseases. Some of these mechanisms are:
Antimicrobial activity
Urtica dioica contains various phytochemicals, such as flavonoids, phenolic acids, amino acids, and fatty acids, that can inhibit the growth of harmful bacteria, fungi, and viruses.
For example, a recent study showed that the aqueous extract of Algerian nettle exhibited high antibacterial activity against some phytopathogens, such as Agrobacterium tumefaciens, Erwinia amylovora, Pseudomonas syringae, and Xanthomonas campestris.
Induced resistance
Urtica dioica can stimulate the immune system of plants, making them more resistant to biotic and abiotic stresses.
For example, a study showed that the foliar application of nettle extract increased the activity of some defense enzymes, such as peroxidase, polyphenol oxidase, and phenylalanine ammonia-lyase, in tomato plants infected by Botrytis cinerea.
Allelopathic activity
Urtica dioica can produce and release substances that can affect the growth and development of other plants, either positively or negatively.
For example, a study showed that the aqueous extract of nettle reduced the germination and growth of some weeds, such as Amaranthus retroflexus, Chenopodium album, and Portulaca oleracea.
