Trifluralin (48% EC)
The mechanism of action:
Trifluralin is a selective herbicide which prevents the germination of the weed seed through cell division blockage in the hypocotyl, as well as the development of the root system. Trifluralin should be sprayed on the surface of the soil before planting and before the growth of the weeds and should be mixed up to a depth of 5-10 cm. Thus, it destroys the seeds of many weeds after germination in the soil but does not affect the weeds that have been green before spraying it. The addition of trifluralin to the soil, as well as being a necessity, has the following advantages: 1. The presence of herbicide up to a depth of 10 cm and adjacent weed seeds causes the weed to be destroyed after germination. 2- After mixing it with the soil, any weeding operation, using a rotavator, or even strong irrigation does not reduce its effectiveness. 3. The mixing of the herbicide with the soil eliminates the need for irrigation or precipitation for activation.
Indications:
Trifluralin is a selective herbicide against many annual stretched wide leaves such as cockscomb, goosefoot, ivy, wild millet types, panicum grass, wild oats, sorghum, mallow, Indian-mallow, wild kenaf, and Lesser canary grass which is applied before weed growth in broad-leaved fields such as cotton, soybeans, sunflowers, beans, sugar beets, carrots, rapeseed and sesame as well as in peas, carrot, lettuce, tomato, onion, garlic, grape, strawberry, sugar canes and ornamental plants. This herbicide is mixed with the soil at a depth of 10 cm before planting. The amount of this herbicide is 2-2.5 liters, and in beans, it is 1-2 liters, which should be sprayed the recommended amount with the required amount of water, and the appropriate sprayer (farm tractor sprayer with nozzle -Teejet nozzle or polyjet backpack sprayer) on the surface of the soil. The amount of required water is 200 to 600 liters per hectare depending on the type of sprayer and nozzle discharge.
Compatibility and Mixing:
Trifluralin is compatible with other herbicides that are consumed in the soil and also used in these cultures.
