Common Pests of Vegetable Crops
Pest monitoring Leafhoppers are collected easily with sweep nets. Yellow sticky traps also are useful in monitoring.
Management-cultural control
Mulches of aluminum foil and straw help reduce disease incidence. Row covers also can be used on higher value crops. Destruction of weed species known to harbor aster yellows is also important.
Management-chemical control: HOME USE
- acetamiprid
- azadirachtin (combined with pyrethrins)-Some formulations are OMRI-listed for organic use.
- bifenthrin (usually combined with zeta-cypermethrin)
- capsaicin-Some formulations are OMRI-listed for organic use
- carbaryl
- imidacloprid
- malathion
- plant essential oils (rosemary, etc.)-Some formulations are OMRI-listed for organic use.
- pyrethrins (often combined with other ingredients)-Some formulations are OMRI-listed for organic use.
- zeta-cypermethrin
