Used for selective control of weeds in citrus and for non-crop weed control.
KROVAR I DF is a biodegradable product used for selective weed control in non-crop sites.
It contains two active ingredients, bromacil and diuron and is formulated as a water-dispersible granule to be mixed in water and applied as a spray suspension.
After application of KROVAR I DF, moisture is necessary to move the active ingredients into the soil.
Once in the soil, bromacil and diuron are available for uptake by germinating weed seeds and plant roots; the products are absorbed to a lesser degree by the leaves of plants.
KROVAR I DF is most readily absorbed through the root system.
Translocation is primarily upward through the xylem, accumulating in the leaf. Once in the leaf, KROVAR I DF inhibits photosynthesis, the process by which plants manufacture food.
The symptoms on a susceptible plant after treatment will be interveinal and veinal chlorosis (yellowing) in older leaves.
Broadleaf plants will also exhibit a brown colouration (necrosis), and grass plants will exhibit a white colouration.
KROVAR I DF affects a susceptible plant's ability to manufacture food, so the plant dies. KROVAR I DF is a residual-type product, remaining in the soil for a period of 1 to 2 years and providing control of emerging weeds until the product is decomposed by natural biological processes.
KROVAR I DF is suspendible in water. The aqueous solubility of the two active ingredients at room temperature (25°C or 77°F) is very low (42 mg/litre) for diuron and low (815 mg/litre) for bromacil.
KROVAR I DF is compatible with most other non-crop herbicides. Before making a tank mixture with
KROVAR I DF, refer to the spray preparation section on the label.
KROVAR I DF in the dry form remains stable in its original unopened container at normal temperatures and storage conditions.
KROVAR I DF is nonvolatile. It does not evaporate readily at normal atmospheric pressures and temperatures.
