Not too much is known about the cabbage seedpod weevil in North Carolina. In fact, NC State University entomologists said we set a new county record for this pest (tell them what they win!) and it had previously only been recorded in the western part of the state.
Organic control strategies: Research has shown that trap crops can be effective, so Doug is evaluating which trap crops would flower before the senposai and be more attractive to the weevils. Parasitic wasps also can help reduce both adult and larval weevil populations so farmscaping to help enhance populations of these parasitoids may be helpful. An organically approved pesticide such as Entrust® or Surround® may provide some control (see Pesticide Use Guidelines).
* These recommendations apply only to North Carolina. They may not be appropriate for conditions in other states and may not comply with laws and regulations outside of North Carolina. Certified organic growers should consult their certifier before using a new pesticide. Unless otherwise noted, these recommendations were current as of June 2009. Individuals who use pesticides are responsible for ensuring that the intended use complies with current regulations and conforms to the product label. Be sure to obtain current information about usage regulations and examine a current product label before applying any pesticide.
