Hi everyone,

After founding out that my phalaenopsis had scale infestation I used the suggested Bayer spray. I was recommended to use more than once if necessary.Since the scales were not visible at the first stage I am not sure whether if I need to use it one more time. A week has passed and first the color become more greener and secondly it is producing a new leaf. Does this signal that the plant is healthy or would it be a wrong assumption?

Many thanks

While you may very well get rid of pests and bacterial diseases, viruses are forever.

Dear raybark,

Sorry that I opened the topics such way. I was basically wondering whether if I should use the insecticide (Bayer) again for scale insects if I see new leaf growth and healthier leaves.

When the plant was diagnosed, I was unable to see the scales itself (even when looking closely) but just seeing bits eaten. That is why I wanted o ask if new leaf growth would mean end of scales or should I do another dose.

Thanks

Hi Deniz
The reason for repeat insecticide is to catch eggs that have yet to hatch from last treatment. It's usually good idea to repeat second spraying.

Most pesticide manufacturers recommend three treatments in a row, typically at one-week intervals precisely for the reason Peter mentioned.

The majority of insecticides on the market only work on adults, and do not have any affect on their eggs or even immature critters. Multiple sprayings in a row generally kills them all, before they have time to reproduce.

A word of caution: after such a treatment regimen, if you get an outbreak in the future, use an insecticide with a different mode of action (MOA) to ensure there is no development of resistant strains.

Dear peterlin and raybark,

Thank you. checked the spray as well and found that it is an instant killer (designed for one time use) for eggs as well. I think almost 2 weeks passed from my initial spraying, would you recommend me to spray again?

Or raybark should I use the probiotic supplement in the way you suggested me for sick plants ?

Thanks
