Is Isoproturon a selective herbicide?

Is Isoproturon a selective herbicide?

Isoproturon 75% WP is a urea based herbicide. It is a selective post emergent herbicide. Is used typically, in cereals to control annual grasses and many broad-leaved weeds.

Is isoproturon toxic?

Isoproturon is of low acute toxicity and low to moderate toxicity following short- and long-term exposures. It does not possess significant genotoxic activity, but it causes marked enzyme induction and liver enlargement.

What is pendimethalin used for?

Pendimethalin is the most widely used preemergent herbicide in the urban residential environment. It is used in the spring and has increasingly replaced bensulide and dacthal. Pendimethalin is also used to control grasses and weeds in field crops.

What is metribuzin herbicide?

Metribuzin is a herbicide used to selectively control certain broadleaf weeds and grassy weed species on a wide range of sites including vegetable and field crops, turf grasses (recreational areas), and non-crop areas.

Is pendimethalin toxic?

In studies using laboratory animals, pendimethalin generally has been shown to be of low acute toxicity. It is slightly toxic by the oral and eye route and has been placed in Toxicity Category III (the second lowest of four categories) for these effects.

Is pendimethalin toxic to humans?

There is dearth of literature on Pendimethalin toxicity, it is considered practically non-toxic to humans. In large ingestions, its toxicity is principally manifested by head ache, nausea, vomiting, sore throat, retching and haematemesis etc. Its toxicity is invariably associated with oral ingestion.

Does metribuzin have residual?

Metribuzin is one of the few residual herbicides that also have substantial burndown activity, primarily through non-systemic activity on small annual weeds. The spectrum of residual control for metribuzin includes most small-seeded annual broadleaf weeds.

What is isoproturon made of?

Isoproturon is a selective, systemic herbicide used in the control of annual grasses and broad-leaved weeds in cereals. Pure isoproturon occurs as colourless crystals which melt at 158°C. It’s slightly soluble in water and polar organic solvents.

Is isoproturon soluble in water?

Pure isoproturon occurs as colourless crystals which melt at 158°C. It’s slightly soluble in water and polar organic solvents. Isoproturon mainly enters the environment during its application as an agricultural herbicide, but releases may also occur during manufacture, transportation and storage.

What is the half life of isoproturon?

Isoproturon has a low tendency to adsorb to soils and is therefore quite able to enter in water bodies despite its rather low water solubility (70,2 mg/l). Its half-life in water is 30 days, in soils 40 days.

What is the Henry’s Law constant for isoproturon?

The Henry’s Law constant for isoproturon is estimated as 1.9X10-9 atm-cu m/mole(SRC) derived from its vapor pressure, 2.47X10-8 mm Hg(1), and water solubility, 65 mg/L(1). This Henry’s Law constant indicates that isoproturon is expected to be essentially nonvolatile from water and moist soil surfaces(2).
