Question: Command for finding algebraic invariant curve

I am wondering if Maple DETools package has functions or command to deal with the following problem: algebraic invariant curve. Some first order ODE preserves such type of curve as their solutions. For example, the following ODE has an algebraic curve y(x)=0 as its particular solutions:

> odetest(y(x)=0, y'(x)=y(x)^3-2*x*y(x)^2,y(x));

> 0

The ODE in general does not have algebraic solutions. The solutions are computed in terms of special functions. In some cases the algebraic curve could have multi-variate forms f(x,y)=0. I am wondering about one question: Does Maple have tools to find solutions of algebraic curve for ODE, without knowing the information of general solutions? I have already tried PDETools:-casesplit, but it seems to classify such curves to the same case to the general solution. 

I will be glad if anyone could give me some advice.
