A kind of herbicidal composition containing terbuthylazine and herbicide and its application

Abstract

The invention discloses a terbuthylazine and bromacil containing weeding composition and application thereof. The terbuthylazine and bromacil containing weeding composition uses terbuthylazine and bromacil in a mass ratio of (1-50): (1-50) as effective components. The terbuthylazine and bromacil containing weeding composition compounds the terbuthylazine and the bromacil, so that the advantages of the terbuthylazine and the bromacil are effectively achieved, the obtained terbuthylazine and bromacil containing weeding composition is excellent in quality and good in pesticide effect, can be applied to a non-cultivated land area or a field planting citrus garden, and has a control effect significantly higher than that of single terbuthylazine or single bromacil; the weeding composition is prepared into big granules, can control the release rate of pesticidal active components, is long in lasting time and relatively low in using amount, and is unlikely to cause pesticidal damage to crops; the big granules are not required to be added into water, dissolved, diluted and sprayed, and can be directly spread onto the surface of soil manually or by airplane, so that the time and the labor are saved, and the weeding composition is convenient and quick; the big granules are not adhered to stems and leaves of the crops, and is small in drift and small in pollution to the environment, so that pesticidal damage caused by direct contact is avoided, and the weeding composition is safe to spreading personnel.

Description

technical field [0001] The invention relates to a herbicidal composition containing terbuthylazine and weededim and its application, in particular to a large-granule herbicidal composition containing terbuthylazine and mebedin and its application, and belongs to the technical field of pesticides. Background technique [0002] Terbutyzine, English common name: terbutylazine, chemical name: 2-chloro-4-tert-butylamino-6-ethylamino-1,3,5-triazine, also known as grass net Jin. Terbutyzine is a white solid with a water solubility of 8.5mg / L (20°C). It is easily soluble in organic solvents, stable in neutral, weak acid, and weak alkaline media, and easily hydrolyzed in strong acid and strong alkali media. Terbutyzine is a broad-spectrum systemic herbicide, which is mainly absorbed through the roots. It is used to control various weeds in soybean fields, sorghum fields, citrus fields, pome fruit fields, vineyards, afforestation on barren hills, and non-cultivated areas. , the dosag...

Problems solved by technology

[0005] In addition, the dosage forms of terbuthylazine and terbuthin are mostly wettable powders and water-dispersible granules. These dosage forms need to be applied in the form of spraying. This method of application is labor-intensive, time-consuming, and labor-intensive. The utilization rate is low, which increases the chance of direct contact between the agent and people, and increases the danger to the sprayer
