VDAL Treated
In order to combat the invasion of germs, Immune System was introduced to organisms, which isolates or destroys most germs. Similarly, in the long-term process of combating pathogens, plants have also formed a complex immune system. Once a plant is attacked by an adverse external environment or disease, cells in the plant will form substances related to resistance to the pathogen through various metabolic pathways, then activate the plant's own immune system and reduce the incidence of disease.


Developed by the Key Laboratory of Plant Physiology and Biochemistry, China Agricultural University, based on the principles of plant immunology, creators of VdAL have studied the use of immune induction technology to activate the plant's immune system, thereby improving crop disease resistance and stress resistance, and becoming a new development direction of green pest control technologies.

University Developed

VDAL™ is an ASPF2-like secreted protein with 297 AA
(Verticillium dahliae Asp-f2 Like)
VDAL™ is produced by biocatalysis, which makes it safe and residue-free (LD>5000 mg/Kg BW)

Biocatalysis production: Safe & environment-friendly.

Low dosage: 15 grams per hectare, 1-2 times per growing season.

Multiple treatments: seed treament (Coating or soaking), foliar spray application.
Improving germanation by VDAL
