Nematode Management in Cole Crops

Management of Root-knot Nematode in Vegetable Crops

Insecticide management strategies for control of swede midge (Diptera: Cecidomyiidae) on cole crops.

Insecticide field trials were conducted in Ontario, Canada, and New York state to identify insecticides effective against the swede midge, Contarinia nasturtii Kieffer (Diptera: Cecidomyiidae), a new invasive pest in North America. Field trials indicated that foliar applications of lambda-cyhalothrin, permethrin, acetamiprid, chlorpyrifos, and dimethoate could provide control of C. nasturtii. F...

Root-knot Nematode Management in Dryland Taro with Tropical Cover Crops.

Twenty-two cover crops were evaluated for their ability to reduce damage by root-knot nematode, Meloidogyne javanica, to taro, Colocastia esculenta, in a tropical cropping system. Cover crops were grown and incorporated into the soil before taro was planted. Barley, greenpanic, glycine, marigold, sesame, sunn hemp, and sorghum x sudangrass DeKalb ST6E were poor or nonhosts to the nematode as me...

Bagrada hilaris (Hemiptera: Pentatomidae), An Invasive Stink Bug Attacking Cole Crops in the Southwestern United States

An invasive stink bug, Bagrada hilaris (Burmeister) (Hemiptera: Pentatomidae), was discovered in theWestern Hemisphere in 2008 near Los Angeles, CA, presumably introduced on container shipments arriving at the Port of Long Beach. In the subsequent 4 years, it has spread throughout southern California, southern areas of Arizona, Nevada, and Utah, southern and west–central New Mexico, and extreme...

Suppression of Plutella xylostella and Trichoplusia ni in cole crops with attracticide formulations.

The three key lepidopteran pests of cole, Brassica oleracea L., crops in North America are diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae); cabbage looper; Trichoplusia ni (Hübner) (Lepidoptera: Noctuidae); and imported cabbageworm, Pieris rapae (L.) (Lepidoptera: Pieridae). Two species-specific pheromone-based experimental attracticide formulations were evaluated against ...
