AGR-226: Identification and Control of Henbit and Purple Deadnettle

Mike Barrett, Gregg Munshaw | Dec. 30, 2016 (New)

Most of the winter annual broadleaf weeds are distinguishable from each other and thus fairly easy to key out or identify. However, there are two that show up each spring that often get people scratching their heads as to which is which--is it purple deadnettle? Or is it henbit? There are several similarities between these weeds--both are members of the mint family, both have square stems, both have sparsely hairy oval- to egg-shaped leaves, leaves of both are opposite, and both have small purple flowers that appear in the axils of the upper leaves during the spring.

AGR-220: A No-math Method of Calibrating Backpack Sprayers and Lawn Care Spray Guns

Gregg Munshaw | Apr. 7, 2016 (New)

Calibrating application equipment is something many people avoid because they believe it is too time consuming or that the math involved in the process is confusing. Calibration, however, is critical. Applying too much can be bad for the environment, injure the grass, and also wastes money. Applying too little can result in poor pest control and can lead to pesticide resistance. There are several methods that will calibrate sprayers but the no-math method is likely the most simple and reduces the chance of errors.

AGR-216: Turfgrasses of Kentucky

Gregg Munshaw | Aug. 17, 2015 (New)

Roughly 7,500 grass species are grown around the world, but only 14 species are adapted as turfgrasses that have been used extensively. Kentucky is situated in the transitional climatic zone of the United States, the middle point between the cool north and the warm south, with warm summers and cool winters. Because of its unusual climate, no single grass is suitable for all situations and locations. The majority of the turfgrasses that are appropriate for use in Kentucky are known as C3 grasses, or cool-season grasses. Cool-season grasses differ from warm-season grasses (C4) in many ways, but most notably in their photosynthetic pathways. Warm-season grasses can tolerate and even thrive during the warm summers while cool-season grasses may become heat-stressed. Conversely, winters in Kentucky may be too cool for warm-season grasses and greenup in the spring may be long and arduous. Warm-season grasses enter a dormancy period during the fall and winter and may stay in this state as long as six or seven months.
