Spider Mite Damage on Giant Pumpkin Leaf
This is the first that I know of a giant pumpkin to be infected with spider mites and as a result the actual diagnosis was delayed simply because spider mites are not common on the scout list for giant pumpkins. However, once the leaves were inspected two spotted spider mites were clearly present in large numbers.
The initial browning was concentrated on only a few older leaves so this was not initially taken as something out of the ordinary. Early on the browning looking like a fungal disease look but then this stippling was noticed which was the reason for the closer inspection. If you think aphids are small… spider mites make aphids look big;-)
Proper diagnosis is very important and these were specifically identified as two-spotted spider mites.
