Texture issue


I’m currently working on a project with several trees in it.
Each tree consists of 2 polygons with some textures on it.
I’ve created 2 Screenshots that display the problem.

The second image shows a strange behaviour.
Some pixels of my tree texture are blue and yellow when I zoom out.

Can somebody help me with this problem?

Thanks in advance
