Embodiment 1

[0019] Example 1: 20% glufosinate-ammonium brassinolide aqueous solution

[0020] Glufosinate-ammonium 19.9998%, brassinolide 0.0002%, alkyl glycoside 5%, lauryl betaine 5%, coconut oil fatty acid diethanolamide 3%, deionized water to make up to 100%; in a blender Complete the entire production process, the specific production step 1, fully dissolve glufosinate-ammonium with deionization, step 2, add brassinolide and mix evenly, step 3, add additives and the remaining water and mix evenly, and then 20% Glufosinate-ammonium brassinolide aqueous solution.

[0021] The dosage of 20% glufosinate-ammonium brassinolide active ingredient in this embodiment is 800-1000 g / ha for preventing weeds in non-cultivated land, and the control effect is 97.61%-100% after 30 days of medicine; The active ingredient dosage of glufosinate-ammonium water agent is 1000 g / ha, and the control effect is 94.08%.

Embodiment 2

[0022] Example two: 40% glufosinate-ammonium propionylbrassinolide dispersible oil suspension

[0023] Glufosinate-ammonium 39.9995%, brassinolide 0.0005%, dioctyl sulfosuccinate sodium salt 6%, polyoxyethylene fatty acid ester 4%, white carbon black 3%, vegetable oil 20%, bentonite 0.8%, formazan The esterified vegetable oil is added to 100%; the above formula is added to the solid material in a sand mill for grinding, mixed with the liquid material under high-speed stirring, and a 40% glufosinate-ammonium brassinolide dispersible oil suspension is obtained .

[0024] In this example, the dosage of 40% glufosinate-ammonium propionylbrassinolide dispersible oil suspension concentrate is 700-900 g / ha for the control of weeds in citrus orchards, and the control effect is 94.37%-99.05% after 30 days of treatment; The control effect of 40% glufosinate-ammonium dispersible oil suspension concentrate at 1000 g / ha is 92.47% under the same conditions.

Embodiment 3

[0025] Embodiment three: 60% essence glufosinate-ammonium brassinolide microemulsion

[0026] Refined glufosinate-ammonium 9.99999%, brassinolide 0.00001%, fatty acid methyl ester 16%, calcium dodecylbenzene sulfonate 4%, epichlorohydrin 5%, acetic acid 1%, water added to 100%; The active ingredient is completely dissolved in a solvent, and then other additives are added, mixed evenly, and water is finally added, and after being fully stirred, a 20% glufosinate-ammonium brassinolide microemulsion can be prepared.

[0027] This embodiment 60% glufosinate-ammonium brassinolide microemulsion active ingredient dosage 700-900 g / ha is used to control weeds in paddy field ridges, and the 30d control effect after the medicine is 96.08%-100%; the same condition uses 60% The control effect of fine glufosinate-ammonium microemulsion was 92.84%.

Abstract

The invention relates to a synergistic weeding composition. The composition includes a synergistic component, a weeding active component and pesticide auxiliary agents. The synergistic component is one of brassinolide or propionyl brassinolide. The weeding active component can be one of glufosinate or glufosinate-P. The weight ratio of the synergistic component to the weeding active component is 1000-1000000:1. The composition improves weeding effects, and the dosage of the weeding active component is reduced, thus reducing harm to surrounding crops and environment pollution caused by pesticides and retarding generation of resistant weeds.

Description

technical field [0001] The invention relates to the technical field of compound pesticide application, which is used for controlling agricultural weeds. Background technique [0002] Glufosinate-ammonium has become the most important herbicide in the world because of its broad-spectrum, environmental friendliness and low toxicity. Conduct conduction. Glufosinate-ammonium has become the second largest herbicide in the world. However, after 2008, with the launch of a series of glufosinate-ammonium products in my country's pesticide market, the price of glufosinate-ammonium dropped sharply, which completely changed the previous use mode of glufosinate-ammonium. and repeated use on various crops / non-cultivated land, the use of glufosinate-ammonium is becoming more and more common, and the dosage has increased significantly. The same cultivated land uses glufosinate-ammonium multiple times a year. Over-reliance and long-term use of herbicides with the same mechanism of action wi...
