Problems solved by technology
Mainly absorbed by roots, less absorbed by stems and leaves, suitable for corn, sorghum, sugarcane, fruit trees, nurseries, woodlands, has a certain inhibitory effect on cruciferous, leguminous weeds and some perennial weeds, and is easily absorbed by rain It is also effective for some deep-rooted grasses by leaching to a deeper layer of the soil, but it is prone to phytotoxicity and has a longer lasting effect

Effect test
Embodiment 1
[0015] Corn 3-4 leaf stage, weeds 2-3 leaf stage application, 30 days after the application of the plant control effect results are as follows
[0016]
[0017] The test showed that the mixed use of nicosulfuron and xieqine had the same control effect as each single agent, and it was safe to crops.
Embodiment 2
[0019] Corn 3-6 leaf stage, weed 2-5 leaf stage application, 35 days after the application, the control effect of the investigated plants is as follows
[0020]
[0021] The test shows that the mixed use of nicosulfuron and xiorazine can expand the herbicidal spectrum, improve the control effect on broadleaf grass, and is safe to crops.

The invention relates to a nicosulfuron-and-atrazine-containing weeding composition. The composition is an oil suspending agent, which contains the following components in percentage by weight: 3 percent of nicosulfuron, 20 percent of atrazine, 10 percent of emulsifier, 20 percent of surfactant and 47 percent of oil. The weeding composition effectively combines the advantages of the nicosulfuron and the atrazine, improves the weeding effect, reduces the residual activity, reduces the herbicide damage to crops, delays the herbicide resistance of weeds and community succession, reduces the using amount of herbicides, reduces environmental pollution, is time-saving, labor-saving and money-saving and alleviates the burden on farmers.
Description
technical field [0001] The invention relates to a herbicidal pesticide composition, especially a herbicidal composition containing nicosulfuron-methyl and atrazine. Background technique [0002] Nicosulfuron is a special herbicide for post-emergence corn fields. It has significant control effect on grass weeds and some broad-leaved weeds in corn fields. It is safe for corn. High activity, good activity only on some broad-leaved weeds, its herbicidal spectrum is narrow. [0003] Atrazine is a systemic selective pre-emergence and post-emergence herbicide. Mainly absorbed by roots, less absorbed by stems and leaves, suitable for corn, sorghum, sugarcane, fruit trees, nurseries, woodlands, has a certain inhibitory effect on cruciferous, leguminous weeds and some perennial weeds, and is easily absorbed by rain It is also effective for some deep-rooted grasses by leaching to a deeper layer of the soil, but it is prone to phytotoxicity and has a longer duration of effect.
