Abstract: This paper deals with a stochastic two-species competitive system. Some very verifiable criteria on the uniformly weakly persistent in the mean almost surely (a.s.) and extinction for each species are obtained. Some examples are given to illustrate our main theoretical findings. Our results are new and complement previously known results.

Keywords: stochastic competitive model; permanence; extinction; time delay.
