Today’s Smart Gardener

The sensible approach to pest control is to create a natural balance of organisms in your yard or garden. In a diverse ecosystem, pest populations are naturally regulated. Development of this balance at your home relies on using products that minimize harm to beneficial organisms.

Plant Health OLD: Commonly accepted to keep plants

healthy was a broad application of chemicals to control pests – prescription pest control.

NOW: Though pesticides play a role in plant health, they also have limitations. In addition to environmental and health concerns, pesticides may give only limited and temporary control if other control measures and practices are not integrated into the overall management or maintenance program.

Practical Procedure for Plant Health

Selecting Appropriate Plants

Grow the right plant in the right place!

Know the requirements of a plant before you buy it

Select disease resistant varieties or cultivars

Select high quality plant material

Plant Health Care Healthy,

productive plants can use their natural defense systems to resist environmental stresses.

As a result, they need less chemical input for survival and productive long-term growth. An especially important concept is the plant health care attempts to manage plant health rather than just control pest problems.

Integrated Pest Management: IPM

Uses multiple tools Uses chemicals when necessary Requires knowledge and planning

Protect garden and landscape from pests

Maintain beneficial organisms Effective pest management with least

negative impact to the environment

True Pest or Just a Nuisance? Accept some level of a pest population as

healthy and natural (remember “diverse”!)

Only consider control of a pest when significant damage occurs, or the presence of a pest poses a real threat

First ask yourself:

Is control really necessary?

Proper Identification of the Pest You can’t control it if you do not know

exactly what it is… Correct ID provides you with valuable

information about the pest including: * life cycle* what stage is most destructive* what stage is most susceptible to control

efforts

Why is the Pest Present? Food, Water, Shelter, Perfect Environment?

Prevention vs. Cure It may be easier and more effective to remove

the reason why the pest is there in the first place vs. controlling the pest!

If we can’t remove the “reason” then let’s make it a less attractive environment for the pest to discourage its presence.

3 Questions to Always Ask:

1. Is the pest really a problem? Or is it just annoying? (Action Threshold)

2. What exactly do I have here? Proper identification of the pest and life cycle stage.

3. Can the environmental factors of why the pest is there be altered to make it a less desirable place for the pest to be?

Turf

According to NASA's Ames Research Center: 50, 000 square miles of the

continental US is covered by lawn

There is 3 times as much irrigated grass as irrigated corn.

Turf is the most widespread irrigated crop.
