Target Pests

Used for selective control of weeds in citrus and for non-crop weed control.

Application

Moisture is necessary to move the herbicide into the root zone of weeds. Best results are obtained if treatment is made to moist soil, and moisture is supplied by rainfall or sprinkler irrigation within two weeks after application. Weed control symptoms are slow to appear and may not become apparent until the herbicide has been carried into the root zone of the weeds by moisture. The degree and duration of control will vary with the amount of herbicide applied, soil texture, rainfall, and other soil and water management practices.

Time to Kill

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.

Active Ingredient

Bromacil 80%, Diuron 40%

How To

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. Broad leaf 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.
