Plant Diseases and Insect Pests

Plant Identification and Plant Disease Identification

Plant identification is critical for Integrated Pest Management (IPM) and the proper use of pesticides in agriculture and horticulture situations. It is also helpful to the clientele that just want information on that weed, flower, shrub or tree growing in their landscape.

Disease organisms such as fungi, bacteria, and viruses can damage and/or kill a wide variety of plant materials in Georgia. It is essential to identify the organism accurately before implementing control strategies.

Insect Identification

Proper diagnosis is necessary to achieve good pest management. It's important to remember that only a small percentage of insects on plants are pests.

Nematode Testing             

Nematodes cause roots to become knotted and galled and impair the root system so that water and nutrients cannot be taken up. Nematode damaged plants become stunted, turn yellow and wilt in hot weather.

The best time to determine if you have a nematode problem is in the summer and fall, when nematodes are most numerous.
