A. As with all yard problems, the first step in controlling weeds, diseases and pests is identification. After the problem is identified, measures can be taken to correct it.
 |
In early spring, treat your lawn as a preventative measure if you have had problems with insects in previous years. Treat with products such as Carbaryl, Dursban, Diazanon or malathion. |
|
In summer months, as the insects move toward the ground surface, treat again. |
|
Some lawn diseases can be controlled with better lawn care practices. Avoid watering lawns where the grass blades will stay damp all night and always get red of dead grass. Keep grass well groomed and well fed. A healthy lawn will be more resistant to attacks from disease. |
|
Brown patch usually occurs after extended periods of wet weather. You can apply a fungicide when the grass first shows signs of damage, and continue until recovery begins. Dollar spot appears as small, circular spots (1 to 3 inches in diameter), during the summer. Common after droughts in Bermuda, Zoysia, St.Augustine, and centipede lawns, a fungicide spray program should be started. |

Leaf spot is a pest of St. Augustine. It first appears on the leaves as tiny spots with a gray center. As it progresses the grass looks scorched. Spray with Daconil 2787. |
|
Rust is identified as yellow, orange or brown spots on grass blades. |
WEED CONTROL
There are two types of weeds - grassy weeds such as crabgrass and foxtail; and broadleaf weeds such as dandelion, clover and chickweed.
Grassy weeds are best controlled using a pre-emergent herbicide applied in early spring, about 2 weeks before the last frost.
Broadleaf weeds can be controlled by spraying with a weed killer that contains 2,4D, MCPP, or dicamba. Be sure to use the proper equipment when applying weed and pest controllers. Remember, please never mix herbicides and always follow manufacturers instructions when using any chemical product.
