What appears to be resistance to certain fungicides has suddenly appeared and you can't seem to manage Pythium blight and dollar spot. What can you do to solve the problem?
What will be an ideal response?
Use reduced 2- or 3-way component mixtures of suggested and unrelated fungicides listed in tables 4.4 and 4.5 . Much of the answer to question 2 is aimed at preventing disease tolerance or resistance problems.

Calculate the BOD of the sewerage stream
The Ganges River, shown in Figure 4.66, has an annual average flow rate of 12,105 m3/s. The average temperature of the Ganges River was reported to be 24.6ºC. The Ganges has become contaminated with raw sewerage and industrial waste so that the dissolved oxygen in the river upstream of sewerage discharges is 4.6 mg/L. Suppose that the raw sewerage that is untreated flows into the Ganges at a rate of 460 m3/s, the temperature is 25ºC, and the dissolved oxygen in the sewerage stream is completely depleted (i.e. DO = 0). How would you develop a plan for improving water quality in the Ganges River?
Suppose the following data was collected to estimated the five-day BOD in the river and sewerage water:
