specific Embodiment approach 1

[0011] Specific embodiment 1: The corn field herbicidal composition of this embodiment is composed of flufenacet, amfentrazone and adjuvants, wherein the weight percentage of flufenacet is 1% to 20%, and the weight of amfentrazone is The percentage is 1% to 30%, and the rest are additives.

specific Embodiment approach 2

[0012] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the weight percentage of flufenacet in the corn field herbicidal composition is 10% to 18%, and the weight percentage of amfentrazone is 20% to 20%. 28%, and the rest are additives. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0013] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that the cornfield herbicidal composition is in the form of water dispersible granules, oil suspension or wettable powder. Others are the same as in the first or second embodiment.

Abstract

The invention discloses a cornfield weeding combination and a using method thereof, relates to pesticide herbicides and using methods thereof and aims to solve the technical field that existing cornfield herbicides are large in residue amount. The cornfield weeding combination is composed of, by weight, 1-20% of flufenacet, 1-30% of amicarbazone and the balance of auxiliaries. After the cornfield weeding combination is applied for 30 days, medicine in soil is almost degraded completely, and the cornfield weeding combination is safe to crops and environment and can be used for cornfield weeding.

Description

technical field [0001] The invention belongs to the technical field of pesticide weeding. Background technique [0002] Atrazine is currently the most widely used herbicide in domestic corn fields. It has great advantages because of its low cost and good effect. However, atrazine has a stable molecular structure and is not easy to degrade after use. A large number of research results show that atrazine has been detected in used water bodies and soils. After long-term use, it can cause certain harm to water, the environment, soil and animals, especially As an environmental hormone, it has been found that it can affect the growth and reproduction of aquatic organisms, may produce degenerative reactions, and is a potential human carcinogen. Amicarbazone is a triazolinone herbicide, which can effectively control broad-leaved weeds in corn fields, and can also control some gramineous weeds, while being safe to corn. However, in recent years, with the application of herbicides y...
