Bayer Advanced has a few things to consider depending on your type of plants and needs.
Granular Extended insect control covers insects on the surface and in the soil.
Granular All In One for Rose and Flower care is a Fertilizer, Insect Control and Disease Control.
Granular Tree and shrub for Fertilizer and Insects.
Normally before anything goes inside as far as tropical, sub tropical, cacti, succulents the get a heavy spray of Bonide Insecticidal Soap or any major brand. They then get a tablespoon of one or two of the above if appropriate.
Stuff that stay on or near the ground including trees gets All In One 3 way no matter if a Rose or Flower. If needed as in Fruit trees and maples they all received a decent spray coat of Copper Fungicide in Fall and another in Spring.
There are a lot of options and great products but I have found using granular when possible is really effective and a lot easier and safer to apply. Some things like Copper or a Streptomycin Bactericide require far more caution when using but most often should be sprayed.
Again there is more out there but stick with solid brand names. And PLEASE wear proper eye protection and whatever else the Company advises.
