Pest Management: An Integrated Approach

Pest Management: An Integrated Approach

Getting your landscape set up in the spring is an in-depth process.  Trees are pruned, soil amended, and the plantings have been accomplished.  Now you have exactly the look you want.  It would be easy to sit back, open a beverage of your choice, and watch it all come together.  Don’t get comfortable just yet, there is a group of pests eyeing your plants.  Insects come in many forms, looking to make a meal from your hard work.  Do not fear though, there is a straightforward way to protect yourself from these creatures.  Integrated pest management is a system of four control approaches designed to mitigate pest damage while minimizing impact on the environment.

Identification is Key

Before any of these steps may begin pests must be identified.  This starts with scouting your landscape via visual inspection.  Insects leave signs of their presence wherever they visit.  Be sure to inspect every part of your plants including the underside of leaves.  Here is where you will find insect eggs or frass (excrement) which are tell-tale signs of activity.  Once discovered, you need to identify your specific pest.  Insects are identified by their mouth parts when assessing plant damage.  Chewing insects remove leaf material (think caterpillars and grasshoppers).  Speckled leaves of brown and yellow is a symptom of piercing/sucking insects such as aphids.  Other times you may only find damage after the fact where black leaves turn out to be covered in sooty mold.  The sooty mold grows on the excreted honeydew of aphids, whiteflies.  Once identified, it is up to you to decide if the level of damage is worth it and how you would like to approach limiting the damage.

The First Three

The first strategy is cultural control wherein you optimize the environment in which your plant grows.  Improved drainage and removal of plants susceptible to insect attack are excellent examples.  You should also look into the lifecycle of insect pests to remove anything that will provide habitat.  The next control is mechanical.  This methodology is the most work intensive but comes with the least environmental impact as insects will be removed by hand.  Biological control is like mechanical control except that removal of the pest is left to natural predators.  There are many, but birds and lady beetles are best known.  Creating habitat for these will help keep insect populations to an acceptable level with the bonus of falling into Florida friendly landscaping philosophies.

Chemicals are Not the Bad Guy

Chemical control is the final approach.  Some may be surprised to find this here, but it is effective.  With the above in place, you may find there are still insect issues.  Chemicals will be your next step but do not feel put off by this approach.  Research the best products for your situation and follow the instructions on the label to the letter.  The label is designed to reduce risk to you and the environment while providing effective pest control.

Insect pests have plagued gardeners since the first person intentionally planted anything.  Controlling these pests using a multipronged approach is the optimal way to reduce damage to your plants while minimizing environmental impact.  Following the methodology in this post will bring a pest free landscape that you and your family will enjoy.  For more information on integrated pest management, see these Ask IFAS documents, or contact your local extension agent for additional information on this and any topic regarding your gardens and more.

A Problem of Anticipation

The feeling is palpable, everyone is ready for spring.  Can you hear them?  The seeds beckoning in their packets, begging you to bury them in the soil.  Every gardener struggles with this dilemma in early spring, but this year will surely be different.  Maybe just maybe I can get my garden planted and watch with bated breath as life peeks its tiny shoots through the soil.  Inevitably, harsh reality will set in with the realization that there will be a freeze dowsing your dreams before they take root.

Trying as that may be there is a respite.  A small group of plants has heard your concerns.  They provide the early spring color we so desperately seek in our landscapes.  The trees and shrubs have answered your cries reaching out in the most beautiful way they know how.  The saucer magnolias (Magnolia x soulangeana) have given us their teacup flowers all purple and perfect.  The azaleas (Rhododendron spp.) are in full swing with all their magnificence shining bright.  There is one tree that stands above them all in Florida landscapes.  This month you’ll begin to see a tree that is the ultimate harbinger of springtime.  A tree so native in the Panhandle that it bears the state’s name within its own.  The tree I am speaking of is the Flowering Dogwood (Cornus florida).

A Tree Described

Florida in this instance derives from the Spanish florido meaning “full of flowers”.  This tree will not disappoint on this front.  A very common home landscape feature, it performs well in zones 5-9A.   Growing between 20-30 feet in height with the spread to match, they may be pruned to a single trunk or allowed to grow in multiples to fit the landscape.  This tree is known for early spring color, and thrives in sun of shade.  Sometime between March and May, a splash of white or pink (sometimes red, cultivar dependent) lasting several weeks will rear up amid your winter scenery.

The showiness of this plant is not a flower, but a protective leaf structure known as a bract.  The true flowers are small yellow to green clusters in the center of these bracts.  Depending on the site conditions, the foliage turns maroon and the flowers to red berries in the autumn.   The spring flowers, and later berries are a useful food source for pollinators and local birds respectively.
