Question: Poorly white
I need help because I'm a little "ignorant" about plant disease.
I have a mandarin and a laurel plant that has developed a soft white animal that infests the branchy parts of both plants. I don't know what it's called or how it is eradicated, so the mandarin has almost reached its end and the laurel is not doing so well.
How can I do?
Citrus cochineal of citrus fruits: Answer: Mal white
Dear Maria Cristina,
Thank you for contacting us about the problems affecting your Mandarin and Laurel plants. From the description of the soft white animals and the current state of your plants, we can believe that the insect that developed on the
mandarin and on the laurel is the Icerya purchassi, a citrus parasite belonging to the mealybug species. Surely the infestation that started from the mandarin plant will later develop also on the laurel plant.
The current infestation of whitish insects can be eliminated with the use of specific products.
So together with this prompt intervention we recommend a simplified program of pathological control and above all of nutritional recovery because a more robust plant is notoriously more resistant. To eliminate the cochineal, the use of mineral oil is recommended.
