Chili plant pests that can harm farmers

Hi friends, nice to meet me @tanicha and I hope you are all well today,
My chili garden is having problems at the moment with the condition of the plants being very poor, I don't understand the problems and diseases of chili plants that are currently emerging, so I have to know how to deal with plant problems like this, the leaves are getting curlier and the fruit is rotting.

The condition of plants that have pests with curly leaves and fruit rotting, really happens a lot in plants nowadays, this is what makes all farmers fail to harvest, therefore I have to find out the consequences of chili plants which are always damaged and cause a lot of damage. death to plants.

There are times when plants that are already bearing fruit show a lot of rot and the fruit stems are falling off, so in this case I also have to be able to understand what is happening, it is really confusing in treating chili plant diseases like this.

Rotting stems cause the chili fruit to fall, but the problem has not yet been resolved properly, and especially with the current unhealthy plants, it makes me even more confused about overcoming this problem.
Below I can show you several parts of chili plants that are affected by pests and diseases. I hope all my friends can provide solutions for my plants below

My hope is that this obstacle will soon be resolved well, and I also hope that in the future I will be enthusiastic again in managing and caring for chili plants that grow well.

Thank You
