As you have noticed, the farms with the highest APY are the ones with:
LABO/WBNB LP (40x Multiplier)
LABO/BUSD LP (40x Multiplier)
In order to farm in these farms, it's needed to previously add liquidity on PancakeSwap. When you are providing liquidity, you also need to be aware of the Risk of Impermanent Loss.
In order to compensate for the risks of Impermanent Loss, farming with those pairs has additional APY.
