ENVIRONMENTAL FATE

Breakdown of Chemical in Soil and Groundwater: Oryzalin is soluble in water and it does not have a strong tendency to adsorb to soil particles. It leaches downward to a limited extent with rainfall and has a moderate potential to contaminate groundwater. Its soil half-life is 20 days. Microbial degradation may be responsible for the breakdown of oryzalin in soils. It is subject to photodecomposition, but not volatilization, at the soil surface. Breakdown of Chemical in Surface Water: Oryzalin has a low solubility in water. There was no observed hydrolysis at pH 5, 7, 9. Breakdown of Chemical in Vegetation: Plant metabolism of oryzalin is minimal. Unmetabolized oryzalin is rarely detected. When used at the recommended level, damage to plants in the following year is not expected.  

Usage: Oryzalin was introduced by DowElanco. Oryzalin is a selective preemergence surface-applied herbicide used for control of annual grasses and broadleaf weeds in fruit trees, nut trees, vineyards, established bermudagrass turf and established ornamentals. It inhibits the growth of germinating weed seeds.

Application: Bud before herbicides, can use or other herbicides in practice. Control the fruit trees, cotton, peanuts, winter rape, soybean and sunflower fields such as the weeds and applicable lawn weeding.
