Photinia, caterpillar-like pests which appeared in late autumn
I have several Photinia red robin planters placed on my balcony.
I have started the preparations for the cold season by applying the potassium fertilizer “Azet Herps Kali” every 7 days for the last 2 weeks.
3 weeks ago I sprayed last time with Mospilan because aphids appeared.
For several days now I have noticed the leaves being eaten more and more. Looking for the pest I have noticed these caterpillars, similar to the one in the picture, inside certain leaves.
What treatment should be applied?Attachments:

Hello. To control them, in the case of ornamental shrubs, we recommend treatments with insecticides such as BactoSpeine DF, 10 g, in a dose of 10 g/10 L water or Deltasap 2.5 EC, 5 ml, in a dose of 5 ml/10 L water. Alternate the treatments according to the evolution of the attack. Specifically, if the first one is carried out with Bactospeine, after 7 days Deltasap will be applied. Spray as finely as possible so as to achieve a uniform distribution of the solution on the plants.
In order for the insecticide solution to remain on the shiny leaves of the shrubs, it is also recommended to add an adjuvant such as Break Thru S 240, 2 ml, in a dose of 2 ml/10 L. 7-10 days after the treatments, it is recommended to use a maintenance product such as Plant Strengthening Fertilizer Brennnessel mit Rainfarn, 350 ml or Contra X, 500 ml, applied directly by spraying. It supports the regeneration of plants after certain stressful conditions, or if they have suffered from pest attacks.-
