ACP found in Tulare County, HLB disease not found

California Citrus Mutual announced the discovery of Asian citrus psyllids in Visalia but no greening disease has been identified


VISALIA – Scientists and farmers alike have been working diligently over the last half decade to rid themselves on the Asian Citrus Psyllid (ACP) and the greening disease Huanglongbing (HLB) it can spread.

The disease has spread across the United State’s sunbelt and has seemingly stopped in southern California. But last week a large population of ACP and nymphs were found in an older section, northwest of Visalia, according to California Citrus Mutual (CCM).

County and State officials have been moving into eradication mode immediately. Making matters worse is that multiple life stages were found in the specific properties. Local homeowners are reportedly cooperating as some 400 ACP were found. Preliminary testing of the trees does not indicate HLB in the area. All four sites have been treated. Precautionary treatments in surrounding area, will commence after a public meeting and notices are distributed to homeowners. There is no commercial citrus within a mile of the location and a survey was conducted with no additional finds. Enforcement staffs are reviewing traps in the area on a daily basis until further notice.

This brings back the reminder that moving cleaning bins through an area is of paramount importance. Bins moving from a packing house into a production area can carry ACP hitchhikers. Growers need to monitor the arrival of said bins inasmuch the transportation routes, in this case Hwy 63, 65, 198, and 99 are vulnerable pathways for ACP distribution. Examples of bins moving into a production area are above. Packing houses need to supply cleaned bins to groves and growers CCM says in a press release.
