Insect Control

NOTES:  For the insecticides listed below, one product trade name and formulation is provided for each active ingredient (AI) as an example of rates, preharvest interval (PHI), restricted entry interval (REI), and special instructions. In many cases, there are other products available with the same AI. Please see Table 26 and Insecticides Alphabetical Listing by Trade Name for more information on these insecticides.

The designation (Bee: L, M, or H) indicates a bee toxicity rating of low, moderate, or high. See the Protecting Honeybees and Native Pollinators section for more details.

The symbol * indicates a product is a restricted use pesticide. See Pesticide Safety and Use for more details.

The symbol OG   indicates a product is listed by the Organic Materials Review Institute (OMRI) as approved for use in organic production. See Organic Certification section for more details.

Floating row covers can exclude beetles, increase yield and produce earlier harvests. Plants should be free of aphids and whiteflies before setting in the field. Apply covers immediately after setting transplants. Completely seal edge of the material with soil, leaving enough slack to allow for plant growth. Use wire hoops to prevent damage to growing tips. Use in conjunction with crop rotation to prevent Colorado potato beetles from emerging underneath. Remove row covers at bloom to prevent plants from becoming leggy and lodging. See Plastic Mulch and Row Covers, and High Tunnels for more information.

Aphids, Green Peach (Myzus persicae ) and Melon (Aphis gossypii)

See melon aphid in the insect control section of Cucumber and green peach aphid (GPA) in the insect control section of Pepper for more information on each of these aphid species.

Aphids generally colonize eggplant during the first 2 weeks of July, and good control at this time with a selective insecticide will prevent the need for sprays later in the season. Good coverage of the underside of leaves is important. Treat when 1 to 2 aphids per leaf are observed. Be aware that broad-spectrum insecticide applications can cause aphid and mite outbreaks by reducing the populations of beneficial organisms.

Reflective mulch, where 50% of the surface area is reflective, will repel colonizing aphids. Even black plastic mulch has been shown to reduce aphid infestations to some extent compared with bare-ground culture.

Colorado Potato Beetle (Leptinotarsa decemlineata)

See Potato for more details on Colorado potato beetle (CPB), including cultural controls and resistance management. In eggplant, CPB feeding may occur in June on young transplants, or later in the season when plants are full grown and fruit is developing. Watch for emergence of summer adults in late July and August, as they can damage leaves, flowers, petioles, including clipping flower buds. This reduces fruit formation and marketable yield. Scout to determine number of adults, egg masses, small and large larvae and to assess feeding damage. The following action thresholds have been established from seedling to fruiting stage: 2 small/1 large larvae per plant (if plant is 6 inches). Avoid using insecticides from the same resistance group more than once per year.

Cutworms

Black cutworm is the most common of the many cutworm species that damage eggplants in New England. The dark-grey or black caterpillars hide under the soil surface adjacent to the plant stem during the day and feed after dark. On rare occasions, large larvae switch from leaf feeding to cutting stems of seedlings. Certain fields tend to have a history of repeated cutworm damage. Scout fields weekly through June after transplanting. Check at least 100 plants for cut stems, especially near field margins. Spot spray damaged areas or edges of the field if 1% or 2% of the plants have been cut down. For best results, make application between midnight and dawn while cutworms are feeding aboveground. Hardening seedlings before transplanting toughens stems and reduces damage. See cutworms in the Pepper section for more information on this pest.

Flea Beetle, Potato (Epitrix cucumeris)

Potato flea beetle feeds primarily on solanaceous crops (eggplant, tomato, pepper and potato), solanaceous weeds (jimsonweed, ground cherry, black nightshade), and other weeds including redroot pigweed and lambsquarters. It does not feed in brassica crops. Adults are 1.5 to 2.0 mm, dull black, short and broad, with a pitted and hairy body. Adult beetles spend the winter protected under leaf litter in field edges near the crop where they were feeding in late summer, and search out weed and crop plants in the spring. Eggs are laid in the soil, larvae feed on roots, and after a pupal stage in the soil, a new generation of adult beetles will emerge. These ‘summer adults’ feed heavily and then move to a protected spot for the winter. Thus there 2 major flushes of adults – one in late May and early June, and the second from mid-July to mid-August. Leaves that are heavily damaged may be riddled with small round ‘shot holes’ that stunt or kill plants. Potatoes, once well established, can withstand considerable feeding damage. Eggplants are vulnerable even at later stages, especially when summer adults emerge and fruit is forming.

Management practices include clean cultivation, crop rotation, removing or avoiding spring weed hosts, using row covers, and applying spot treatments targeting eggplants along the field edges. Scout to observe beetles and damage. Treat newly set transplants if they have 2 flea beetles per plant, seedlings 3" to 6" tall if they have greater than 4 beetles per plant, and plants over 6" tall if they have 8 beetles per plant. Most insecticides registered to control CPB, including spinosad, will control FB. Systemics applied to the soil at transplanting may control both flea beetle and Colorado potato beetle; avoid using the same chemical group for both soil and foliar treatments.

Pepper Maggot (Zonosemata electa)

Some farms with high population of pepper maggot experience damage on eggplant, especially when peppers are rotated out of the field. Perimeter trap cropping can help limit damage to eggplant. Plant 1 or 2 rows of cherry peppers around the perimeter of the eggplant and spot spray the trap crop (only) when the first stings (egg-laying scars) occur on the peppers or adult flies are captured on traps. See pepper maggot in Pepper section for more details and for effective insecticides for peppers.

Potato Leafhopper (Empoasca fabae)

Potato leafhopper feeding is toxic to eggplant. Leaf margins and tips turn yellow and curl up. Feeding can reduce yield before damage is visible. Damage is often confused with Verticillium wilt, where leaves turn yellow and droop down. Treatment is recommended if there is an average of more than 1 to 1.5 leafhoppers per leaf. See potato leafhopper in the Potato section for more information.

Two-spotted Spider Mite (Tetranychus urticae)

Two-spotted spider mite (TSSM) is the most common mite species that attacks vegetable crops in New England and feeds on tomato, eggplant, potato, beans, vine crops such as melons and cucumbers, and other crops.  In eggplant, TSSM is a key insect pest. Adult females are approximately 1/50" long, slightly orange or pale green in color with 2 dark spots on their body, and lay up to 100 eggs over their 3 to 4-week lifespan. Eggs are globular and amber red when viewed with a 10X hand legs. Eggs hatch in about 3 days and immediately begin feeding. Following two brief nymphal stages, they become adults and start laying eggs in 1 to 3 days. The life cycle can be completed in 7 to 14 days, depending on temperature.

Foliar damage results from piercing plant tissue with their mouth-parts and removing plant fluids. Feeding injury often gives the top leaf surfaces a mottled or speckled, dull or bronzed appearance. Mites cover the leaves with fine webbing. Other symptoms include distorted leaves, stunting and overall loss of plant vigor (in spite of adequate moisture and nutrition), whitening or spotting of leaves, yellowing of the plant or some of the leaves, and in some cases loss of foliage and death. Spider mites are favored and by hot, dry, dusty conditions, which also aggravates injury by stressing the plant, and by excess nitrogen which fosters succulent growth. Damage is often underestimated or goes unnoticed since the wounds and the pest are not easy to see without close inspection.

Overhead irrigation or prolonged periods of rain can help reduce populations. Do not over-fertilize. Avoid weedy fields and do not plant eggplant adjacent to legume forage crops. Avoid planting eggplant near dusty, high-traffic farm roads. Scout by searching leaves for symptoms and webbing, and using a 10 to 15X hand lens to identify mites. Use selective products and avoid broad-spectrum insecticides for this and other pests wherever possible, because outbreaks are often caused by the use of broad-spectrum insecticides that interfere with the numerous natural enemies that help to manage mite populations. With most miticides (except those with a long residual such as bifenazate), use 2 applications, approximately 5 to 7 days apart, to help control immature mites that were in the egg stage and protected during the first application. Alternate between products after 2 applications to help prevent or delay resistance. Preventative releases of the predatory mite, Phytoseiulus persimilis, may suppress TSSM populations, as they do in strawberry fields. Releases must be made when TSSM numbers are low. Amblyseius fallicis is a predatory mite that is widely used in greenhouses. See Vegetable Transplant section on insect and mite management and on scouting guidelines and biological control for information.
