Oxadiazon is a nitrogen-containing heterocyclic herbicide, which is white crystal, odorless, non-hygroscopic, and its 12% EC. It can exert herbicidal activity under the action of light, and it can be absorbed by plant sprouts, roots, stems and leaves, causing it to stop growing, and then rot and die; at the same time, its herbicidal activity is 5-10 times higher than that of fenben, and its effect on stems and leaves Larger, the resistance of rice roots is stronger. It is mainly used for weeding in paddy fields, and also commonly used in peanuts, soybeans, cotton, potatoes, sugar cane, tea gardens, orchards, etc. to prevent and control annual grass weeds and broad-leaved weeds.

Mechanism of action of oxadiazone

Selective pre-emergence and post-emergence herbicides, used in paddy and dry fields, soil treatment, cause action through contact and absorption of weed sprouts or seedlings. Post-emergence spraying, the weeds absorb through the aboveground part, and the pesticide accumulates in the vigorous growth part after entering the plant, inhibiting the growth and causing the weed tissue to rot and die. The herbicidal effect can only be exerted under light conditions, but it does not affect the Hill reaction of photosynthesis. Weeds are sensitive to the drug from germination to the 2-3 leaf stage, and the effect of applying the drug at the germination stage is the best, and the effect decreases with the growth of weeds. After being applied in paddy fields, the medicinal solution spreads quickly on the water surface, is quickly absorbed by the soil, does not easily move downwards, and is not absorbed by the roots. It metabolizes slowly in the soil and has a half-life of 2 to 6 months.

Applications of Oxadiazon

Contact pre-emergence and post-emergence herbicide. For soil treatment, paddy field use. It works mainly through the absorption of weed buds and stems and leaves, and can exert good herbicidal activity under the condition of light. It is especially sensitive to weeds in the germination stage. When the weeds germinate, the growth of the bud sheaths is inhibited, and the tissues rot rapidly, and the weeds die. It can also be used to control annual grass weeds and broad-leaved weeds in crops such as cotton, soybean, sunflower, peanut, potato, sugar cane, celery, and fruit trees.

It is used to control a variety of annual monocotyledonous and dicotyledonous weeds. It is mainly used for weeding in paddy fields. It is also effective for peanuts, cotton, sugarcane, etc. in dry fields. It is a selective herbicide in the pre-emergent and post-emergent stages, and is usually used in soil treatment. Control dicotyledonous weeds, especially suitable for removing weeds such as barnyardgrass and broad-leaved annual weeds in rice. The drug effect lasts for a long time, and there is no drug harm.

It is also used in soybeans, cotton, corn and horticultural crops. It can be made into emulsifiable concentrate, powder, wettable powder, etc.

How to use oxadiazone

When the paddy field is in a state of muddy water after water preparation, use the bottle throwing method to apply the pesticide, keep the water layer of 3-5cm, and transplant the seedlings 1-2 days after the application. The application dosage in the southern region is 240-360g/hm2, and the application dosage in the northern region is 360-480g/hm2. Do not drain water within 48 hours after spraying, but if the water level increases after transplanting, it should be drained until the water layer is 3-5 cm, so as to avoid submerging the seedlings and affecting growth.


For rice transplanting fields, weak seedlings, small seedlings or exceeding the conventional dosage, when the water layer is too deep to submerge the heart leaves, phytotoxicity is prone to occur. (2) When used in dry fields, soil wetting is conducive to the efficacy of the drug.
