Signs on watermelon
- ▸ Bronze-colored egg clusters on leaf undersides
- ▸ Wilting and yellow speckled foliage (looks like spider mite damage)
- ▸ Adult bugs and gray nymphs gathered on leaves and stems
- ▸ Damaged fruit with sunken spots
IPM controls
- ✓ Hand-pick adults and crush egg clusters every few days
- ✓ Place boards on the ground near plants — bugs hide under at night, flip and squash in morning
- ✓ Targeted insecticide on nymphs (adults are tough)
- ✓ Sanitation: remove crop residue at season end to deny overwintering sites
