Underhill Nastek - Early Stress Detection Glasses

Disease, drought and weed invasion are plant and turf killers. But by the time you see them it can be too late. Underhill™ Nastek ™ Early Stress Detection Glasses allow you to see plant and turf stress 2-10 days before it is visible to the naked eye. You now have a great new weapon against some old enemies.

Technology developed by NASA scientists, now lets you spot stressed turf close up or at a distance, with plenty of time to react to correct unhealthy conditions.

These unique lenses block out green color reflected from chlorophyll in healthy turf, causing it to look black or gray. Since the human eye is so sensitive to light in the green color range, any off green color(s) (caused by disease, water, or pests) will stand out against the black background as glowing red, coral, pink or other hues…allowing problem turf to be quickly identified. What was invisible is now seen
