Usually, Harpin Protein acted as a plant health promoter activates a plant’s immune system, which triggers growth and defence genes.
When harpin protein contacts with plants’ receptors on their seeds, roots, and leaves, it will trigger an early warning system — “Systemic Acquired Resistance,” leading to increased plant yields and health.
Target Crops: Economic crops such as cannabis, tobacco, Asparagus, avocado, mango, grape, citrus, blueberry, kiwi, apple, grape, plum, cherry, blueberry, avocado, nectarine etc.
Mechanism of Harpin Protein
It works by stimulating the plant to grow under the general effects of stress and one of those stresses is fungal attack.
Harpin itself does not directly affect the pathogens, nor does it enter the plant, rather it binds to receptors on the plant leaf and thereby triggers physiological processes within the plant.
Features of Harpin Protein
- Increases plant yield and quality
- Improves nutrients uptake ability
- Help crop defend against plant diseases
- Extend fruits shelf-life 5-7 days
- Increase fruit sugars 10%-25%
- Increase calcium uptake by＞20%
Applications of Harpin Protein
1.Induce Crops to Prevent Diseases
Harpin is an environmentally-friendly elicitor
of disease resistance. It can induce 70 kinds of disease resistance, the prevention rate & control effect of the disease is from 40%-80%.
2. Increase Plant Immunity
Stimulate crop strong repairing ability to the diseases caused by many types of adverse environmental damage. Especially for post-disaster recovery of crops, quickly promote crops’ regeneration. Restore growth and development capacity. Greatly reduce the losses caused by disasters.
3. Stimulate Plant Growth
Promote plant growth and development, self-repair, nutrient absorption, and transportation, and achieve high quality and high yield, significantly increase crop yield and quality can increase crop yield by 10-55%.
