Other claims from this paper (5)

Association Greater leaf damage yielded higher photocell readings.
Method / resource The device linked light readings to removed soybean leaf tissue.
Method / resource Damage position produced low standard errors and generally nonsignificant F ratios.
Method / resource The device attained high accuracy for damage samples no larger than 0.836 in.2.
Observation Sixth-instar feeding accounted for 69.1% of consumed leaf surface.
