Recommended Spray On Citrus Pest

Heavily infested leaves of variegated orange.

A lady fruit tree enthusiast sent us a photo of a seriously infested variegated orange. She wanted to know what she could do to control the infestation. Because we wanted to be sure of the answer, we contacted our good friend, Dr. Rodel Maghirang of UP Los Baños who immediately responded. He said he would consult an expert he knew. The recommendation the expert gave is to spray the infested plant with Actara or Thiametoxam. These are available in agricultural supply stores. Please take a look at the picture. You might have a similar problem.

ADDITIONAL INFO: When Dr. Reynaldo Lantin, a backyard citrus grower, saw the picture in this post, he sent his comment to share his experience in trying to control  the infestation similar to that in the picture above. The same pest had infested his prized Kino sweet orange seedling he got from a Pakistani friend.

We quote: “The control that I used was to wet a sponge (Scotchbrite) with a mild solution of soap powder (Tide) and carefully wiped away the white spots. The citrus plant seemed to regain its vigor and I may have to repeat the process for mopping up operation. I hope this information would be of help to the micro-scale growers (backyard) of citrus like me.”

NEW INFO: ORGANIC OPTION TO CHECK THE PEST – Dr. Rodel Maghirang has sent us (July 18) a new option to check the citrus pest. Soap or detergent diluted with water is used to wipe the leaves then followed by spraying with Entomopathogenic fungi developed by Dr. Jonar Yago of the Nueva Vizcaya State University. In 3 to 4 days, the infestation is reduced. Dr. Yago can be contacted at (0975) 239-2138.

  1. If I am not mistaken, the white spots on the leaves are the same as those on the main stem and branches (but only a few on the leaves) of my 60-cm tall prized Kino sweet orange seedling I have acquired through a Pakistani friend.

    Similar infestations have killed some of my former citrus seedlings.
