Since there exists no chemical able to cure virus-infected plants, it is advised to prevent infection in the first place and eradicate infected plants.

To do so, the easy way is to use clean and sanitized tools.

Because the plant viruses are transported by aphids probing or feeding on plants, the aphid population in the greenhouse must be controlled with biological methods since these methods are environmentally friendlier than the chemical ones.

This scientific article reviews aphid parasitoids and predators that can be used in biological control.

Alternatively, one can cultivate cultivars tolerant or resistant to cucumber mosaic virus.

I wish you to be successful in your scientific work.

With kind regards..

These biocontrol agents are environmentally friendlier than the chemical ones.

As described by Zhang, Y. et al, Insects 2021, 12, 1131. https://doi.org/10.3390/insects12121131 and others, the expression levels of viral protein genes and host or vector genes changed significantly, up and down, depending on the dose of imidacloprid. As I recall from studies of Vigor Effect (R), neonicotinoids interact with plant stress response mechanisms, but this interaction has not been well studied so far.
