Hi I have a guava and lemon plant
I am having problem with possible pest infestation
I have been using Yates pyrethrium insect pest gun which I have used over the top and bottom of leaves in a dry weather.
I can still see the leaves wrinkling with discolouration.
Do you have a solution to it ?

can you see any physical pests on the undersides of the leaves?

no physical pests sighted as yet

I see what looks like leaf miner trails in #1. Plant #2 looks like it might have rust.

Despite spraying pesticides, am not able to get rid of leaf miner on my lemon plant. What would be best solution for rust on the grave leaves which i imagine is fungal disease ?

Do i need to remove the infected leaves ? If yes just trim it from the base ?
