Problems solved by technology

[0003] Atrazine is a systemic selective pre-emergence and post-emergence herbicide. It is mainly absorbed by roots and has little absorption by stems and leaves. It is suitable for corn, sorghum, sugarcane, fruit trees, nurseries, woodlands, and against cruciferous and leguminous weeds. and some perennial weeds have a certain inhibitory effect, and are easily washed by rainwater to the deeper soil layers, and are also effective for some deep-rooted weeds, but are prone to phytotoxicity and have a longer duration

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.

Abstract

The invention relates to a nicosulfuron and atrazine oil suspending agent composition. The composition is an oil suspending agent and comprises the following components in percentage by weight: 4 percent of nicosulfuron, 48 percent of atrazine, 10 percent of emulsifying agent, 15 percent of surfactant and 23 percent of oil. A weed control composition has the advantages of effectively combining the advantages of the nicosulfuron and the atrazine, enhancing weed control effect, lowering residual activity, reducing chemical injury to crops, delaying the occurrence of medicament resistance of weeds and community succession, reducing the using amount of a medicament, reducing environmental pollution, saving time, labor and money and lightening burden on farmers.

Description

technical field [0001] The invention relates to a herbicidal pesticide composition, especially a composition of nicosulfuron-methyl and atrazine oil suspension. 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. It is mainly absorbed by roots and has little absorption by stems and leaves. It is suitable for corn, sorghum, sugarcane, fruit trees, nurseries, woodlands, and against cruciferous and leguminous weeds. And some perennial weeds have a certain inhibitory effect, and it is easy to be washed by rainwater to the deeper soil layer. It is also effective for some deep-rooted weeds, but it is easy to cause phytotoxicity and has a long ...
