Spraying with insecticidal soap is effective, but read the label for dilution rates and directions.
2.
The highest specific growth rates ( ? max ) cells can attain is equal to the critical dilution rate ( D c ):
3.
Now is a prime time for controlling them by spraying with horticultural oil ( following the label instructions for summer dilution rate or growing season rate ).
4.
In traditional fermentation systems, the dilution rate must be carefully controlled as it affects the concentration of bacterial cells and toxic end-products ( organic acids and solvents ) inside the fermenter.
5.
A . As long as you follow the label directions and use the summer dilution rate, 1 percent or 2 percent, rather than the dormant rate of 3 percent or 4 percent, your shrubs should not have a problem.
6.
This gives a vessel dilution rate of about 13 % w / w per hour; the amount of broth and culture mass being removed and then made back up per hour, with respect to the total mass in the vessel.
7.
If a dilution rate is chosen that is higher than ? max, the cells cannot grow at a rate as fast as the rate with which they are being removed so the culture will not be able to sustain itself in the bioreactor, and will wash out.
