of 20 ppm dip solution, that each bulb absorbs 5 ml of solution, and that the solution is used until half of it (50 liters) is consumed, it can be calculated that at least 10,000 bulbs can be treated, with a cost of slightly more than 0.5 cents per bulb (less than 2 cents per 6” pot
with 3 bulbs). In real practice, it is likely the final chemical cost per bulb would be lower than this.
