Cycad Aulacaspis Scale CAS

Over the coarse of the last several years, southern US landscapes have lost as much as 70% of their king and queen sagos (cycads) due to the relentless attack of Cycad Aulacaspis Scale (CAS), a small white scale from Asia.

CAS is first noticed after it has established on the undersides of the dark green fronds changing them to a glowing white, so that the Cycads resemble a small flocked Christmas tree. This flocked appearance is somewhat attractive, but the Sagos react adversely to the piercing-sucking feeding activity of this scale and turn brown and die within a quick two to three year period.

Forestry Distributing stocks a wide range of products for the management and control of Cycad Aulacaspis Scale (CAS). 

• Systemic treatments applied as soil drenches have proven to provide the most effective control including the insecticides Safari 20SG (Dinotefuran) and Zylam Liquid (Dinotefuran);  
• Insect growth regulators including Distance IGR;
• Insecticides including, Merit (Imidacloprid) and Dimethoate 400 (Dimethoate)
