Grower Infrormation

DORMANT SPRAYS

The Texas Citrus Pest & Disease Management Corporation (TCPDMC) encourages you to employ dormant sprays this winter to control Asian citrus psyllid (ACP).

We understand that inclement weather conditions and/or harvest activities can present a challenge to accessing your groves in a timely manner for treatment but we encourage you to take advantage of both winter spray windows to ensure that your 2018 spring flush is ACP-free.

Due to late rains at the beginning of the season, the fall flush cycle that we typically see from September thru mid October was extended as young shoots were actively growing. ACP egg & nymph stages were present well into early November. The first dormant spray was applied in  ZONE 1: November 20 – December 9, 2017, and in ZONE 2: November 27 – December 16, 2017.

Based on existing conditions, we recommend that growers also consider adding a pesticide for proactive control of rust mite, red scale, scab and greasy spot.

In cooperation with the Texas A&M Kingsville-Citrus Center, the following treatment windows are recommended:

The second dormant spray should be applied between the following dates:

ZONE 1 & ZONE 2: February 5 – February 24, 2018

In the event that prolonged inclement weather-related issues are encountered, we will revise spray dates and get you that information in a timely manner.
