Pests and Diseases

 

A daily check of your plants will work wonders, regularly examine their leaves from top and bottom and treat any harmful creepy crawlies you see immediately. The earlier they are caught, the better your chances of getting rid of them. In the early stages, insects may be removed by hand picking or spritzing the leaves with a stream of water.

See, carefully, if your Citrina has some of the symptoms as follow. These are the most common pest in Citrus. Many of these pests are so small that they can only be seen if you use a magnifying glass.

All of them can be treated with biologic products sold in any garden center near you.
