It has been my experience as a Specialist grower of Hibiscus that  the most common dilemma the gardener is confronted with, is the accurate identification & the tell tale signs to look for when their Hibiscus plants have been under attack by pests & diseases, rather than just the control methods.

This Web Page has been created in effort to assist in the identification of  those pests & diseases that effect Hibiscus.
The list is not conclusive & invitations to additions are most welcome and  will be included as requested.

Much attention has been spent on using graphical images, close-up photography, life cycles, tell tale signs, specific habits of each pest & the damage inflicted upon the plant.
Scientific name usage has been deliberately kept to a minimum in an effort to concentrate on the visual identification at the home gardener level.

The mission of this Web Page project has been reached once the gardener is satisfied with the  identification of the pest and or diseases that has affected their Hibiscus plant.
Then it's not so difficult to seek out an appropriate warrantable prevention & or control method to use.

There are two very common forms of eating methods used by insect pests, they are Chewing, Sucking & a not so common Rasping.
It is important to understand which pest does what for ease of identification & the consequent  control.
Slugs, Snails, Mites, &  Nematodes etc. attack plant tissue differently & will be listed under, "Other" Heading along with rasping Thrip.

Fungi, Virus, Bacteria & Lichen are listed under "Fungi" Heading.

Plant Disorders, although not a pest & / or disease in the strict sense have been listed last.
It has been decided to place them in that order for greater ease for searching.

GREEN HEADER BUTTONS have been used to categorize these lists.
By clicking on one of these buttons of your choice, you will be taken directly  to the start of that page list to speed up the enquiry.
Alternatively, if you are familiar with your identification search & want to see more detail, you may click directly on one of the alphabetically listed titles & this will take you to that specific target.
It is anticipated that as time goes by & new data becomes available, these pages will be updated & no doubt, with your help,  will expand.

Chemical control measures for Pests & Diseases have not been included in this project to date. For reasons of varied regulations in different countries & regions of chemical legal applictions & usage.
If you wish that I include Chemical control within this project in the future, please indicate your opinions & I will contemplate the insertions.
