Problems solved by technology

[0003] Penoxsulam is a triazolopyrimidine sulfonamide herbicide, which acts by inhibiting acetolactate synthase (ALS), absorbs through weed leaves, sheaths or roots, and transmits to meristems, causing weeds It stops growing, turns yellow, and then dies. It is used to control barnyardgrass, Alisma, Echinacea, Sagittarius and annual Cyperaceae weeds in rice fields, and has residual activity against

Abstract

The invention relates to the technical field of pesticides, and discloses a rice field compound herbicide. The compound includes two active components comprising penoxsulam and pyribenzoxim, wherein the weight ratio of penoxsulam to pyribenzoxim is 1:32-8:1, and the mass percentage content of the penoxsulam and the pyribenzoxim in the compound herbicide is 0.1-80%. The above herbicide composition is used for preventing and killing weeds in the rice field, has reasonable components, has an obvious compounding synergism, has a better preventing and killing effect than individual application of the components, enlarges the weed control spectrum, reduces the control cost, alleviates the weed resistance generation, is safe to crops, and accords with safety requirements on pesticide preparations.

Description

【Technical field】 [0001] The invention belongs to the field of agricultural plant protection, and relates to a herbicide composition, in particular to a herbicide synergistic composition containing two active ingredients of penoxsulam and saflufenacil. 【Background technique】 [0002] Rice is not only the most important food crop in my country, but also one of the main food crops in the world. Nearly half of the world's population feeds on rice, and with the growth of the global population, the demand for food in many countries continues to increase, especially rice. The application of 2,4-D in Japan around 1950 opened up the initial stage of chemical weeding in paddy fields, and has continued to develop since then, and it has been more than 50 years. During this process, the herbicide varieties have been continuously improved and perfected, the selectivity has been gradually enhanced, and the herbicidal spectrum has been continuously expanded. It is an indispensable and imp...
