Bean Leaf Beetle


Orange-red or green with black head and black spots.

Adult beetles lay eggs in soil at the base of seedlings.

The eggs hatch into larvae which feed underground on

roots and stems, making stems weak and easily broken

in wind or during picking, before they become adult

beetles. Adults riddle leaves, especially on early bean



Super-Light Insect Barriers are very

effective. Grub-Away Nematodes, applied at or shortly

after planting time, control larvae. If it is already

too late or if the beetles have flown in from surrounding

areas, use PyolaTM Insecticidal

Spray (at our test farm we found it more effective

than rotenone) when damage first occurs; if damage continues

at unacceptable levels, follow up weekly for 2 or 3
