What grasses does oxadiazon herbicide kill?

Methomyl is a pre-emergence and post-emergence herbicide that has the characteristics of low toxicity, good ecological benefits, safety to crops, ease of use, and wide applicability to crops. Therefore, it is widely used in agriculture. So what grasses does oxadiazon herbicide kill? Let’s learn more about it below.

What grasses does oxadiazon herbicide kill?

Methomyl herbicide can be used in crops such as rice, soybeans, cotton, sugarcane and orchards to control barnyard grass, lycopodii, paspalum, sedge, alkali grass, duckweed, cucurbita, knotweed, as well as annual broad-leaved weeds in the Poaceae family, such as Amaranthaceae, Chenopodiaceae, Euphorbiaceae, Oxalidaceae and Convolvulaceae.

How to use oxadiazon herbicide?

1. Usage

1. Rice

(1) Dry fields: After sowing dry rice and before seedlings emerge, use 100-150 ml of 2% emulsion per mu, add 30-50 kg of water, and spray evenly.

(2) Rice seedling fields and direct-seeding fields: After land preparation, preferably when the field is still muddy, spray 100-150 ml of 12% emulsion oil per mu, add 30 kg of water, and spray evenly.

2. Peanut and cotton fields

Mainly closed. After sowing and before seedlings emerge, use about 200-300 ml of 12% emulsion per mu, add 30-50 kg of water, and spray evenly.

3. Sugarcane fields

Before planting and seedlings emerge, and before weeds sprout out of the soil, use 150-200 ml of 25% emulsion per acre, diluted with 30-40 kg of water and spray. Be careful not to apply pesticides after sugarcane seedlings emerge, otherwise it is easy to cause pesticide damage.

4. Tea garden and orchard

Before weeds germinate in large numbers in early spring, use 500 ml of 25% emulsifiable concentrate per acre and add 50-60 kg of water for spraying.

5. Garlic, onion, potato

After sowing and before seedlings emerge, before weeds emerge, use 100-200 ml of 25% emulsion per acre and add 40 kg of water for spraying.

2. Precautions for use

(1) Dosage and concentration: Determine the appropriate dosage and concentration based on crop type, growth stage and weed situation.

(2) Spraying time: Spray when the sunlight is weak, such as in the morning, evening or on cloudy days. Avoid applying pesticides under strong sunlight to reduce the risk of pesticide evaporation and crop damage.

(3) Safety interval period: Comply with the regulations on the safety interval period and ensure that the use of oxadiazon herbicide is stopped within a sufficient period of time before crop harvest to reduce the potential harm of residual drugs to crops and humans.

(4) Usage: Methomyl can be used for both pre-emergence blocking and post-emergence selective weed control. In actual production, seedling blocking is the main method.

(5) Safety measures: When applying pesticides, you should wear protective equipment such as masks, gloves, and rubber shoes to avoid direct contact with the pesticide solution.



In general, the herbicide oxadiazon has a good weed control effect. However, when using oxadiazon herbicide, be sure to follow the correct usage and precautions to achieve the best weed control effect and protect crop safety.
