Embodiment 1

[0064] Embodiment 1:20% caprylic acid and dimethyltetrachlorsodium aqueous emulsion

[0065] The herbicide is composed of 10% capric acid, 10% sodium dimethyltetrachloride, 100% water and fully mixed to obtain 20% caprylic acid and sodium dimethyltetrachloride aqueous emulsion.

[0066] This embodiment herbicide is applied to non-cultivated land to prevent and control perennial and annual non-cultivated land weeds: present embodiment 20% caprylic acid and dimethyltetrachlorsodium water emulsion add water dilution spray by 5302.5g.a.i / ha, 15 days after the medicine to total grass The plant control effect was 96.72%, and the fresh weight control effect was 91.67%. Matched group 1 single-use 20% lanolin acid water emulsion by 5002.5g.a.i / ha, matched group 2 single-use 200g / L dimethyltetrachloride aqueous agent by 300g.a.i / ha, add water dilution spray respectively, 15 days after the medicine The plant control effects of total grasses were 43.10% and 40.74% respectively; the fresh...

Embodiment 2

[0067] Embodiment 2: 25% caprylic acid and dimethyltetrachlorsodium emulsifiable concentrate

[0068] The composition of the herbicide by mass percentage is 10% capric acid, 15% sodium dimethyltetrachloride, 5% calcium dodecylbenzenesulfonate (emulsifier, dispersant), 5% alkylphenol formaldehyde resin polyoxyethylene ether (Emulsifying agent, wetting agent) 5%, xylene and toluene are added to 100%, mix to homogeneous liquid phase, promptly make 25% caprylic acid and dimethyltetrachlorosodium emulsifiable concentrate.

[0069] This embodiment herbicide is applied to non-cultivated land to prevent and control annual and perennial weeds: 25% lanolin and dimethyltetrachlorosodium emulsifiable concentrate add water dilution spraying by 5302.5g.a.i / ha, and 15 days after the medicine is 98.61 to the plant control effect of total grass %, fresh weight control effect is 94.38%. Matched group 1 single-use 20% lanolin acid water emulsion by 5002.5g.a.i / ha, matched group 2 single-use 200...

Abstract

The invention discloses herbicide composition containing caprylic acid and MCPA-Na and an application of the herbicide composition. The main active components of the herbicide composition comprise caprylic acid and MCPA-Na. The herbicide composition can be prepared into any pesticide allowable dosage form. The herbicide composition enlarges the herbicidal spectrum, has better effects on both broadleaved weeds and grassy weeds and shows a good synergistic effect in a certain ratio range, the herbicidal effect of the composition is improved to a certain extent as compared with a single agent, meanwhile, residues of the herbicide are reduced, and potential threat of the herbicide to the ecological environment is relieved.

Description

technical field [0001] The invention relates to the technical field of herbicides, in particular to a herbicide composition containing capric acid and sodium dimethyltetrachloride 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 and sodium dimethyltetrachloride are mixed at a ratio of 2:1 and 1:1, it shows a synergistic effect on barnyard grass. Mixed use of herbicides can effectively control a variety of non-cultivated weeds such as nightshade, cow chickweed, foxtail and sage. [0003] Sodium dimethyltetrachloride is a phenoxyacetic acid selective systemic conduction h...
