Spinach Leafminer

Description: Adult is a small black and yellow fly (seldom seen).The adult fly lays eggs on underside of leaves; tiny yellowish larvae (1/8" long) hatch and tunnel inside leaves. Several generations develop each summer. It is the most destructive pest of spinach; also infests red beets. Tunnels cause whitish dead areas, making the leaves undesirable; plant growth may be stunted.

Solution: Spray beet tops and spinach with Oil-AwayTM Insecticidal Spray or Eco-OilTM Insecticidal Spray. Ensure coverage on the underside of leaves. Super-Light Insect Barriers provide a highly effective defense against leafminers on both spinach and beets.
