Green Kyllinga

Category: Weed-i-pedia Tagged , |

Green kyllinga and false green kyllinga are very similar in appearance, and both are referred to as green kyllinga. Both species are native to Asia and are spreading rapidly in turfgrasses in the southern United States. Both are perennial species with well-developed rhizomes. Kyllingas tend to have a finer leaf texture and are shorter growing than other sedges. They thrive under close mowing situations (inch or less) and are very prolific in areas that are poorly drained or frequently wet. These two species are mat-forming sedges and have been observed to take over turfgrasses in the southeastern United States. Green kyllinga is very difficult to control once the large mats form. The range of these two species is somewhat misleading because they are spreading rapidly. It is believed that spread of these two species may be due to a change in crabgrass control practices in recent years.  Thanks to NC STATE TURFFILES for this content.

How Does Prodiamine Work?

Category: Weed-i-pedia Tagged , , , |

When you take a look at the Crabgrass Germination Map below, you realize how early Spring really comes in the world of weeds.  Depending on weather and where you live, crabgrass could begin germinating as early as January.  At Stone Brothers & Byrd, we recommend Prodiamine for effective pre-emergent control of tough weeds like crabgrass, dallisgrass and many others.

How Does Prodiamine Work?

Pre-emergent herbicides like Prodiamine have a 3-4 month residual in the soil.  An application in January will provide continued protection through March, which is when most weeds will become active.  Mix 2-3 tablespoons of Prodiamine to one gallon of water to cover 1,000 square feet.  As weeds begin to germinate, Prodiamine will sterilize the seed growth before it reaches the critical bi-foliar stage.  Remember that Prodiamine is a non-selective herbicide.  This means that it will effect all emerging seeds.  If you plan to sow grass seed, make sure that your 3-4 month active window of Prodiamine control has past.  With this consideration in mind, you can make continued applications of pre-emergent up to three times per year.  This can provide year-round control.
