The Texas Citrus Pest & Disease Management Corporation (TCPDMC) encourages you to employ dormant sprays this winter to control Asian citrus psyllid (ACP).
To continue our HLB mitigation efforts in commercial groves, we strongly recommend that you control overwintering populations of the Asian citrus psyllid (ACP) by spraying during these defined windows:
1st Spray Application: November 16 – November 29, 2020
2nd Spray Application: February 8 – February 21, 2021
ACP can quickly colonize untreated groves and initiate high populations whenever new flush shoots are produced on trees. The higher the numbers of ACP, the higher the risk of HLB spread. With these dormant sprays, we can significantly reduce ACP populations, thus reducing the risk of HLB spread in our groves. All growers are highly encouraged to implement these sprays for a uniform reduction of ACP populations in our citrus production area during this entire winter dormant period. With your cooperation in these actions, we will continue to slow the spread of citrus greening here in the Rio Grande Valley.
