Temperature ranges from summer to winter are extreme and limit the kinds of grasses that will grow. Rainfall and soil pH vary considerably from eastern to western Kansas. The extreme, variable and unpredictable combinations of temperature, rainfall, humidity, sun intensity, day length and wind often put considerable stress on turfgrasses growing in Kansas. Only a few months of each year offer ideal growing conditions. Both kinds of grasses are grown in Kansas, but neither is as well adapted here as farther north or south.
Some problems are quite selective to the class or kind of grass.
Some problems arise from improper selection of a turfgrass species or cultivar. The wrong grass for the wrong situation will result in continual problems that are difficult to combat, even with good management and pesticide application. Problems develop when turfgrasses are unable to withstand environmental stress or when good management cannot offset the effects of environ-mental stress. Then pesticides can be a valuable aid to management. Determine the kind of grass or grasses involved.
