Burgh uses Bug-type Pokémon. His ace is Leavanny. Fire, Flying, and Rock-type moves are super effective. Darumaka (Route 4) or a well-trained Pidove/Tranquill can be very effective. Watch out for his Whirlipede's Venoshock if your Pokémon are poisoned. Focus on hitting hard with super-effective moves to take them down quickly.
