In terms of plant disease, the traditional means are various artificial chemical fungicides. However, today people have higher and higher requirements for food safety, and the restrictions on the use of various crops are becoming more and more strict. For example, the American safety requirement of cannabis which we have introduced before (https://www.ultraplantled.com/news/why-your-cannabis-grow-light-needs-uv-77491.html).
In fact, with the popularity of Led Plant Lights, controllable lighting conditions have been proven to be an important means of plant disease treatment.
A study by Bahian University in Israel proves this. The university's research is against downy mildew, which is commonly found in basil. The fungus, which reproduces by spores at night, causes basil to turn yellow and purple and lose its aroma. In fact, this disease is not unique to basil, it is also common in important crops such as cucumbers and corn.
The researchers exposed infected basil leaves to 5 or 10 micromoles of blue, green, red or incandescent light at night. They were incubated for 20 hours in a growth chamber under humid conditions at 20°C. The results showed that red light (peak at 625 nm) inhibited sporulation by 99.7%, regardless of whether the leaf surface was exposed to light.
It is worth noting that the team mentioned that other teams have previously studied the response of the same disease to light in different plants such as cucumber and tobacco leaves, but the conclusion is that the effect of blue light is better.
That indicates 2 points:
1/ Effective inhibition and treatment of plant diseases not only requires the wavelength of light, but also controls the time of light according to the pathogenesis
2/ The same disease but different types of bacteria may require different specific light.
Therefore, in terms of choosing grow light, the one with spectrum modulation + lighting time management can give growers higher value. Most of the plant lights on the market are traditional plant lights with a fixed spectrum.
Ultra Plant™, as a new generation of plant lights, breaks the routine, with full spectrum + 100% adjustable + intelligent setting control to maximize the effect and benefits of plant lights.
