On this page of the BioShock game guide, you can find a detailed Farmer's Market walkthrough. In this place, there are, among other things, the Insect Swarm plasmid and a station for improving weapons. One of the most important areas of the market is the apiary, where you need to get up to 7 samples of the enzyme.

08-At the apiary, you need to get 7 samples of the enzyme. There are even more than necessary. 3 are in the safe on the left. Use the lever from the chimney to temporarily get rid of the threat from the bees, then run into the apiary and start investigating the hives. You will hear the ticking of the clock, which is speeding up the countdown to turning off the chimney. In addition, you will be bothered by Splicers running into the room. Once you have collected all the enzyme samples, exit and continue North.
09 - when you find yourself in the wine cellar, get rid of the turrets and cameras before searching for a recording. Go down the stairs to the basement.
Recording: "Functional Children" - Tenenbaum
10-in the wine cellar, you need to find 7 bottles of distilled water. It's simple-just keep your eyes open. On one of the Western walls you will see a hole where you can jump. You will find there a lot of ammo and a tonic: the photographer's eye. The lowest level of the winery is a large area, but there is nothing interesting there, except for the "power to the people" station (see the map). Once you have 7 bottles of distilled water, you can return to Arcadia (01).
