Quali-Pro® Prodiamine 4L is a professional-grade liquid pre-emergent herbicide designed to provide season-long control of many annual grassy and broadleaf weeds. Formulated with 40.8% prodiamine, this flowable concentrate helps prevent weeds from establishing by stopping newly germinating seeds before they develop.

Ideal for use on established turfgrass, lawns, ornamentals, sod farms, and Christmas tree farms, Prodiamine 4L helps control problem weeds such as crabgrass, annual bluegrass, chickweed, henbit, knotweed, foxtail, and spurge. Its low solubility and low volatility allow it to remain in the weed germination zone for extended protection. This formulation provides reliable performance with low use rates and a low-staining formulation.

How It Works

Prodiamine 4L works as a pre-emergent herbicide by inhibiting cell division in newly germinating weed seeds. This prevents weeds from establishing in treated areas.

For effective activation, approximately 0.5 inches of rainfall or irrigation is required after application to move the product into the soil where weed seeds germinate.

CHOKING HAZARD
Flavor Name: Bone (S), Size: 6 Count (Pack of 1)
CHOKING HAZARD: I purchased these bones for my small Yorki.. He ate the first two without incident; however, on the third bone he unfortunately choked. As the bones wear down, they become extremely stringy, and those strands do not appear to be digestible. I had to rush my dog to the emergency room, which cost $700. Three days later, he became even sicker because he was unable to pass the remaining portion of the bone still in his stomach. I then had to take him to his regular veterinarian, where he was admitted overnight and diagnosed with pancreatitis and a severely irritated gastrointestinal tract. This entire ordeal cost me over $1,500 in addition to the initial $700 emergency visit. I am grateful that my dog is now alive and well, but these bones pose a serious choking hazard and do not digest properly. I strongly caution other pet owners, especially those with small dogs.
