Embodiment 1

[0065] Embodiment 1: 20% caprylic acid and diquat aqueous emulsion

[0066] The herbicide is composed of 10% capric acid, 10% diquat, water is added to 100%, and fully mixed to prepare 20% capric acid and diquat aqueous emulsion.

Embodiment 2

[0068] Example 2: 25% Caprylic Acid and Diquat EC

[0069] The composition of the herbicide by mass percentage is caprylic acid 10%, diquat 15%, calcium dodecylbenzenesulfonate (emulsifier, dispersant) 5%, alkylphenol formaldehyde resin polyoxyethylene ether (emulsifying agent, wetting agent) 5%, xylene and toluene are added to 100%, mixed to a uniform liquid phase, that is, 25% caprylic acid and diquat emulsifiable concentrate is prepared.

[0070] This embodiment herbicide is applied to non-cultivated land to control annual and perennial weeds: 25% lanolin and diquat emulsifiable oil are diluted with water by 5302.5g.a.i / ha and sprayed, and the plant control effect to total grass is 96.04%, 15 days after the medicine. The fresh weight control effect is 93.35%. Control group 1 uses 20% lanolin acid water emulsion alone by 5002.5g.a.i / ha, and control group 2 uses 200g / L diquat water agent alone by 300g.a.i / ha, respectively add water to dilute and spray, 15 days after the medi...

Abstract

The invention discloses an herbicide composition containing hircic acid and diquat as well as application thereof. The main active ingredients of the herbicide composition comprise the hircic acid andthe diquat. The dosage form of the herbicide composition can be any dosage form allowed by pesticides. The herbicide composition shows a very good synergistic effect within a certain proportion range, and has a certain improved weeding effect than a single agent; and at the same time, the herbicide residue is reduced, and a potential threat of the herbicide to ecological environment is also reduced.

Description

technical field [0001] The invention relates to the technical field of herbicides, in particular to a herbicide composition containing caprylic acid and diquat and application thereof. Background technique [0002] Single use of a certain herbicide has been difficult to control the harm of a variety of mixed weeds. Therefore, the combination of herbicides, that is, mixing / mixing, has attracted more and more attention. Herbicide combination is an important means in the chemical control of weeds in farmland, and is widely used in crop fields and non-cultivated land. According to reports, when glufosinate-ammonium is mixed with MCM at the ratio of 2:1 and 1:1, it shows a synergistic effect on barnyardgrass. Mixed use of herbicides can effectively control a variety of non-cultivated weeds such as nightshade, cow chickweed, foxtail and sage. [0003] Diquat is a bipyridyl contact biocidal herbicide researched and developed by the British Bunemen Chemical Industry Co., Ltd., an...
