St. Augustine Grass & White Aphids

St. Augustine grass (Stenotaphrum secundatum) is a medium green colored, warm season grass with moderate water requirement. The grass is well tolerant of shade, drought and salt. White aphids, a potential problem on all forms of vegetation, are also likely to infest St. Augustine grass.

  1. Description

    • White aphids are pests common to all turf grasses including St. Augustine. The pests are soft bodied and pear shaped with a waxy coating that lends them the white color. The long legged insects have antennae and piercing mouths.

    Damage

    • Aphids damage grass by feeding on sap or juice from the blades. Damage is characterized by the appearance of brown spots or lesions on grass blades. As aphid feeding progresses, lawn starts to brown in large patches. Since aphids are very small in size, the damage is evident before the pests. Look for pest presence on the margins of green and brown grass.

    Control

    • You can control aphids by introducing natural predators like parasitic wasps, syrphid fly and lady beetles in infested grass. Chemical control options include the use of acephate, malathion and permethrin.
