Slants are better suited than agar plates, because they can be capped, preventing the agar and the culture from drying out. The cap also prevents airborne contaminants from entering the slant. Also, slants take up less storage space than an agar plate.
The purpose of using a streak plate in microbiology experiments is to isolate and separate individual bacterial colonies for further study and identification.
One disadvantage of using biopesticides is that they may have a slower effect compared to synthetic chemical pesticides.
You do a streak plate in order to get isolated colonies. If you inoculate into a slant, you have less surface area to work and less chance of getting isolated colonies. In broth, you'll definitely get growth but you won't know WHAT is growing. You go back into each quadrant (a little) with your loop in order to "dilute" the bacteria and get colonies. Quadrant 1 is pretty think (like a smear on the plate) but by the time you get to Quadrants 3 and 4, you should see more defined colonies and not just a film of bacteria.

One fail safe way to obtain a pure culture is the streak plate method. This is the best of several ways to obtain a PC. Streak plates allow us to isolate a particular microbe from a mixed culture. A small amount of desired microbe is obtained with a sterile loop, and a single colony is grown on a separate quadrant of the agar plate, or ideally another agar plate all together. One advantage to this method is that a skilled student can, if experienced and skilled, recolonize one particular type of bacteria/microbe up to three times on one agar plate, wherefore less materials are used. Another significant benefit is that this is one of the quickest methods. Another method of obtaining a pure culture is the pour plate method. Pour plating is a method of separating one species of bacteria from another by diluting one loopful of organism into three liquefied nutrient agar plates, with the hopes that one of the plates poured will provide an ideal sample for isolation. An advantage to this method is that it requires far less skill than the first method, however requires far more materials and time.
The following are some advantages of an agar plate verses a slant tube: 1. Surface area- An agar plate has a much larger surface area: a. Easier to isolate individual colonies using the streak-plate method. i. Evaluate the colony shape, margin and elevation. b. Can grow a larger number of cells. 2. Growth- An agar plate allows you to quantify the number of colonies on an agar plate, provided it is within the 30-300 range. Whereas the slant tube cannot quantify growth but only describes growth as none, slight, moderate, or large.

An advantage of using a synthetic fertilizer is that it is an inexpensive solution. They also may contain every nutrient the soil needs, so there is no need to buy other products.
