How do I enable or disable a ParticleRenderer attached to an object in script?

I want to disable the ParticleRenderer attached to GameObject(Ball1) in script.

ball1 = GameObject.Find("Ball1");
ball1.ParticleRenderer.enabled = false;

that second line gives an error. How do I do this. Thanks

Using GetComponent works:

ball1 = GameObject.Find("Ball1");
ball1.GetComponent(ParticleRenderer).enabled = false;

If you're using #pragma strict or on the iPhone, you'll need to cast it as a Renderer:

(ball1.GetComponent(ParticleRenderer) as Renderer).enabled = false;

Depending on your setup, you could instead disable the ParticleEmitter:

ball1.particleEmitter.enabled = false;
