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 by picking or spritzing the leaves with a stream of water.

See, carefully, if your Citrina has some of the following symptoms. These are the most common pests 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 Citrina or in any garden center near you.

Citrus Flower Moth

The moth caterpillar hides in the flower buds, where it feeds and destroys the flowers. Its activity is particularly visible by the cluster of dried flower buds, webs, droppings and vegetable debris, which forms during feeding (sometimes the flower buds detach themselves and are trapped by fine webs).



Both the young and adult phases, the thrips attack the leaves, feeding on the sap of the plants, causing the folding of the edges up and the discolouration whitish. When feeding on the floral gums causes deformations in the bark of the fruit.
