This product is derived from the secondary metabolite of actinomycetes (No. D19) isolated from seafloor sediments, which contains a new structure of polyketoids, which have significant biological activity in inhibiting plant viruses. By activating multiple signaling pathways in plant cells, the compound increases the expression of plant protection protein, strengthens the self-protection ability of plant cells, and prevents the replication behavior of the virus, thus inhibiting the expansion of the virus in the plant.
Before the onset or early onset of viral disease, dilute 500-1000 times to foliar spray, dilute 1000 times for prevention, dilute 500 times for treatment, and use with water grass plant immune protein and oligosaccharide has a better effect.
