To help consultants, growers, regulators and others in citrus-growing regions understand the risk factors behind the survey, the Plant Management Network has released a Web seminar titled, "Risk-Based Residential NLB/ACP Survey for California, Texas and Arizona".

The survey's goal is to target manpower and resources where they will best address the pest problem, according to a news release.

The presentation focuses on urban environments since they can have a large number of citrus trees that aren't treated for pests. Many times, these urban landscapes are adjacent to or interspersed among commercial citrus groves.

As a result, psyllids can build up quickly and migrate into nearby commercial citrus.

Where citrus greening, also known as huanglongbing or HLB, is present, the larger the psyllid population, the greater the chance of HLB infection.

Tim Gottwald, a U.S. Department of Agriculture Agricultural Research Service plant pathologist in Ft. Pierce, Fla., narrates the 46-minute Web presentation.

The Web seminar is produced by the Plant Management Network, a non-profit collaboration among the American Phytopathological Society, American Society of Agronomy and Crop Science Society of America.
