Embodiment 1

[0035] Formulation example 1: 11% glufosinate-ammonium and acifluorfen microemulsion

[0036] The following substances are all percentages by weight: 10% glufosinate-ammonium, 5% alkylphenol polyoxyethylene ether, 5% polyquaternium, and 5% sodium lauroyl sarcosinate are dissolved in water (water phase) at room temperature; Acifluorfen 1.0%, completely dissolved in 8% chloralkane ester (oil phase), add the oil phase to the water phase at a speed of 4000 rpm, and continue high-shearing for 15 minutes to obtain 11% glufosinate Phosphine and acifluorfen microemulsion.

[0037] This embodiment is used to control annual weeds in paddy fields. The dosage of 11% glufosinate-ammonium water agent and acifluorfen EC is 15 g / mu mixed with water and sprayed, and the control effect is 90.6% 30 days after the application. In contrast, the dosage of 11% glufosinate-ammonium water spray was 20 g / mu mixed with 45 kg of water, and the control effect was 71.3% 30 days after the application. In ...

Embodiment 2

[0039] Formulation example 2: 24% glufosinate-ammonium and acifluorfen microemulsion

[0040] The following substances are all percentages by weight: at normal temperature, glufosinate-ammonium 4%, polyethylene glycol oleate 5%, polyethylene glycol lauryl castor oil polyoxyethylene ether 2%, polyoxyethylene lauryl ether 3%, nitrogen Ketone 5%, fatty alcohol polyoxyethylene ether sulfate 5% dissolved in water (water phase); acifluorfen 20%, dissolved in 10% turpentine, 8% chloroalkyl ester (oil phase), at 3000 rpm Under the rotating speed per minute, the oil phase is added into the water phase, and the high shear is continued for 15 minutes to obtain a 24% glufosinate-ammonium and acifluorfen microemulsion.

[0041] This embodiment is used to control annual weeds in paddy fields. The dosage of 24% glufosinate-ammonium aciflufen wettable powder preparation is 15 g / mu mixed with 45 kg of water for spraying, and the control effect is 93.3% after 30 days of application. In contras...

Embodiment 3

[0043]Embodiment 3: 30% glufosinate-ammonium · acifluorfen microemulsion

[0044] The following substances are all percentages by weight: glufosinate-ammonium 20%, polyethylene glycol oleate, polyethylene glycol laurate 3%, polyoxyethylene cetyl ether 3%, polyquaternium ammonium salt at normal temperature 5%, betaine 5%, ammonium sulfate 4% dissolved in water (aqueous phase); 10% of acifluorfen, completely dissolved in 5% chloroalkyl ester, 5% diethyl phthalate, (oil phase), at 2000 rpm, the oil phase was added to the water phase, and the high shear was continued for 15 minutes to obtain a 30% glufosinate-ammonium and acifluorfen microemulsion.

[0045] This embodiment is used for controlling annual weeds in paddy fields, 30% glufosinate-ammonium fluorfen microemulsion preparation dosage 25 grams / mu is mixed with water 45 kilograms sprays, and the control effect is 87.2% in 30 days after the medicine. In contrast, the dosage of 30% glufosinate-ammonium water spray was 20 g / mu...

Abstract

The invention discloses a pesticide micro-emulsion containing glufosinate ammonium and fluoroglycofen-ethyl. A weight part ratio of the glufosinate ammonium to the fluoroglycofen-ethyl in the micro-emulsion is 10:1 to 1:10, the weight sum of the glufosinate ammonium and fluoroglycofen-ethyl in the above pesticide composition is 1-30%, and the micro-emulsion also contains 3-20% of a solvent, 3-10% of an emulsifier, 1-15% of a synergist, and the balance of water. The pesticide micro-emulsion is suitable for controlling annual or perennial dicotylous and gramineous weeds and field broad leaf weeds. The micro-emulsion has an obvious synergistic control effect on the annual weeds than single doses, reduces the use dosage of a pesticide, reduces the pesticide use cost, prolongs the service life of medicines, reduces the unfavorable influences of the pesticides on the ecologic environment, and provides a certain technologic reference for the preparation of a high-salt system micro-emulsion.

Description

technical field [0001] The pesticide composition microemulsion involved in the present invention uses glufosinate-ammonium and acifluorfen as active ingredients to control annual or perennial dicotyledonous and gramineous weeds and field broad-leaved weeds. Background technique [0002] Glufosinate-ammonium, also known as glufosinate, is a non-selective foliar sprayed organophosphate herbicide, which was first synthesized and developed by the Federal German Hoechst Chemical Company in 1979. The herbicidal action mechanism of glufosinate-ammonium is that after absorption by the leaves, it has a partial systemic effect, and can be transferred from the base of the leaves to the ends, less transferred to other parts of the plant, and is harmless to unearthed young shoots and seeds. The ammonium metabolism in the plant is in disorder in a short period of time after the application of the pesticide, and ammonium ions, a strong cytotoxic agent, accumulate in the plant, causing the ...
