Please excuse my absence of "proper format", because I'm relatively inexperienced about writing answers.
Items which inflict status conditions:
Flame Orb : Tries to burn holder at the end of each turn.
Toxic Orb: Tries to badly posion holder at the end of each turn.
King's Rock: Has a 10% chance to cause flinching when the holder's move damages the enemy, provided it has no initial flinch chance.
No item explicitly deals a status condition to the enemy, you have to improvise and think of new tactics.
Using item swap moves like Trick and Switcheroo.
Or...using the move fling. With new items released every generation, this move is getting more and more confusing.
Fling makes the user throws its held item at the enemy. Power depends on item.

I have collected info from this website finding it to be reliable.
Here's the list of items inflicting status conditions and their base power in brackets.
Flame Orb(30): Burns the target
King's Rock(30): Causes the target to flinch
Light Ball(30): Paralyzes the target
Poison Barb(70): Poisons the target
Razor Fang(30): Causes the target to flinch
Toxic Orb(30) : Badly poisons the target
While status inflicting moves are much prefered to these, you can use these if you have some strategies!
