Abstract
Description
Technical Field
[0001] This invention belongs to the field of agricultural chemical applications, and specifically relates to a herbicidal composition. Background Technology
[0002] The chemical formula of glufosinate is C5H. 12 NO4P, with a molecular weight of 198.1574, is chemically named 2-amino-4-[hydroxy(methyl)phosphono]butanoic acid ammonium; (RS)-2-amino-4-(hydroxymethoxyphosphono)butanoic acid ammonium. It is readily soluble in water but sparingly soluble in organic solvents, photostable, and has a melting point of 210℃. It is a highly effective, low-toxicity, non-selective contact phosphate herbicide. Glufosinate-ammonium is an L-type glufosinate-ammonium, and its herbicidal activity is twice that of racemic DL-type glufosinate-ammonium mixtures. Glufosinate-ammonium and / or granulated glufosinate-ammonium inhibit glutamine synthase, leading to nitrogen metabolism disorders in plants, ammonium ion accumulation and poisoning, which in turn affects chloroplast synthesis, hinders photosynthesis, and ultimately causes plant death. Glufosinate and / or glufosinate-ammonium have low toxicity and are relatively safe. They are easily degraded in soil, safe for crops, have a broad spectrum of weed control, high activity, and rapid weed killing. They can control or quickly kill more than 100 kinds of annual or perennial weeds. Glufosinate and / or glufosinate-ammonium primarily act as contact herbicides and do not migrate elsewhere, making them safe for subsequent crops. Glufosinate and / or glufosinate-ammonium have excellent water solubility, stable structure, and are easy to process and mix for use.
[0003] However, due to the characteristics and mechanism of action of glufosinate and / or glufosinate, they are suitable for use at temperatures above 20°C. However, their efficacy deteriorates when used at low temperatures below 15°C. There are few studies and reports on how to improve the efficacy of glufosinate and / or glufosinate at low temperatures. Summary of the Invention
[0004] The purpose of this invention is to provide a herbicidal composition that can improve the efficacy of glufosinate and / or succinate at low temperatures.
[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:
[0006] The first aspect of the present invention provides a herbicidal composition comprising glufosinate and / or succinate, and a foliar fertilizer; said foliar fertilizer is one or more of potassium hydrogen phthalate, boron, ammonium sulfate, and urea.
[0007] Foliar fertilizer is a fertilizer applied directly to the leaves of crops for absorption. Plant leaves have two layers of epidermis, composed of epidermal cells. The outer layer of these cells has a cuticle and a waxy layer, which protect the mesophyll cells beneath the epidermis from adverse external conditions, allowing them to perform photosynthesis and respiration. The leaf surface also has many tiny stomata, which facilitate gas exchange. Research shows that the cuticle is composed of a long-chain fatty acid polymer with hydroxyl and carboxyl groups. The intermolecular gaps and the hydrophilic hydroxyl and carboxyl groups on the polymer allow aqueous solutions to penetrate into the leaf. Of course, the stomata on the leaf surface provide an even more convenient channel for foliar fertilizer to enter the leaf.
[0008] The inventors have unexpectedly discovered that the combined use of glufosinate and / or granulated glufosinate with specific foliar fertilizers can have a synergistic effect, significantly improving the efficacy of glufosinate and / or granulated glufosinate under low-temperature conditions. The specific mechanism may be that foliar fertilizers are a type of fertilizer where nutrients are applied to the surface of crop leaves and absorbed through the leaves. With foliar fertilization, various nutrients can be quickly absorbed by the crop leaves, entering the plant directly from the leaves and participating in the crop's metabolism. Because nutrients enter the plant directly from the leaves, the absorption rate is rapid, greatly increasing the amount of nutrients in the plant within a short period. This leads to an increase in the accumulation of ammonium ions in the plant under low-temperature conditions, thereby improving the efficacy of glufosinate and / or granulated glufosinate at low temperatures.
[0009] According to some specific embodiments, the foliar fertilizer includes at least boron, for example, the foliar fertilizer is boron, or boron and potassium hydrogen phthalate, or boron and ammonium sulfate, or boron and urea, or boron, potassium hydrogen phthalate and ammonium sulfate, or boron, potassium hydrogen phthalate and urea, or boron, ammonium sulfate and urea, or potassium hydrogen phthalate, boron, ammonium sulfate and urea, or potassium hydrogen phthalate, boron, ammonium sulfate and urea.

[0167] 1.2 Test subjects
[0168] The main weeds between the rows of grapevines were barnyard grass, foxtail grass, crabgrass, and purslane, with fleabane being the dominant perennial weed. At the time of herbicide application, the weed coverage in each treatment plot was 80%, with plant height ranging from 15 to 30 cm.
[0169] 1.3 Experimental Design
[0170] The experiment included 16 treatments, each with a control (CK). Each plot was 66 square meters, with three replicates, for a total of 51 plots. The plots for each treatment were arranged in a completely randomized block design. The treatment design is shown in Table 17.

[0173]
[0174] 1.4 Test Environment Conditions
[0175] The experiment was conducted in Daxin Town, Zhangjiagang City, Jiangsu Province, using a 5-year-old vineyard as the experimental site. The experimental field was flat and had sandy loam soil.
[0176] Test weather: On the day of application, the weather was cloudy with a high of 14°C and a low of 4°C, and no wind. There was no rainfall for 3 days after application.
[0177] 1.5 Test Methods
[0178] The experiment was conducted on the afternoon of March 17, 2022. A backpack electric sprayer was used for spraying, with a protective cover installed. The spraying was directed at the weeds between the grape rows, and efforts were made to avoid spraying the pesticide onto the grapes. Each treatment used 30L of water per acre.
[0179] 2. Survey methods and efficacy evaluation methods
[0180] The control effects of each treatment were investigated 14 and 30 days after application. A three-point sampling method was used, with 0.5 square meters selected at each point, and the types and number of weeds were recorded. The impact on grapevines was also visually assessed.
[0181]
[0182] The survey results are shown in Table 18 below.
[0183] Table 18
[0184]
[0185]
[0186] As shown in Table 18, compared with the comparative and control agents, the combination of glufosinate / ammonium glufosinate and foliar fertilizer in the examples significantly improved the control efficacy against both annual and perennial weeds under low temperature conditions.
[0187] As can be seen from the comparison of Examples 2-4, different amounts of boron have different synergistic effects on glufosinate, and the synergistic effect will decrease after exceeding a certain amount.
[0188] Examples 9 and 12 show that the combination of glufosinate / glufosinate with boron, urea, and potassium hydrogen phthalate resulted in the most significant synergistic effect.
[0189] Comparative Examples 1-3 are combinations of glufosinate with other foliar fertilizers, but their synergistic effect on glufosinate is not obvious, and they even have a certain inhibitory effect on the efficacy of glufosinate.
[0190] The grapes in all the above treatment groups grew normally, indicating that the agents in the examples and comparative examples are safe for grapes.

[0386] Efficacy tests of soluble granules for controlling field weeds in vineyards in Examples 27 to 38 and Comparative Examples 9 to 12.
[0387] Application method: Dilute with 30 liters of water per acre and spray evenly in each plot.
[0388] Application time: When weeds are in the early or middle stage of the field, spray the stems and leaves once.
[0389] Survey methods and efficacy calculations:
[0390] The study investigated annual and perennial grass and broadleaf weeds, focusing on their control efficacy against weeds 14 and 30 days after application.
[0391] The purpose of this experiment was to confirm the actual control efficacy of glufosinate and / or succinate combined with foliar fertilizer against inter-row weeds in vineyards, and to comprehensively evaluate the combination of glufosinate and / or succinate with foliar fertilizer, providing a theoretical basis for future applications. The experiment was conducted in accordance with GB / T 17980-2000, the guidelines for field efficacy trials of pesticides.
[0392] 1. Materials and Methods
[0393] 1.1 Test reagents
[0394] Control agents: compound formulations of glufosinate and / or granulated glufosinate with foliar fertilizers, etc., as detailed in Examples 27-38 and Comparative Examples 9-12.
[0395] 1.2 Test subjects
[0396] The main weeds between the rows of grapevines were barnyard grass, foxtail grass, crabgrass, and purslane, with fleabane being the dominant perennial weed. At the time of herbicide application, the weed coverage in each treatment plot was 80%, with plant height ranging from 15 to 30 cm.
[0397] 1.3 Experimental Design
[0398] The experiment included 16 treatments, each with a control (CK). Each plot was 66 square meters, with three replicates, for a total of 39 plots. The plots for each treatment were arranged in a completely randomized block design. The treatment design is shown in Table 53.
[0399] Table 53
[0400]
[0401]
[0402] 1.4 Test Environment Conditions
[0403] The experiment was conducted in Daxin Town, Zhangjiagang City, Jiangsu Province, using a 5-year-old vineyard as the experimental site. The experimental field was flat and had sandy loam soil.
[0404] Test weather: On the day of application, the weather was cloudy with a high of 12°C and a low of 6°C, and no wind. There was no rainfall for 3 days after application.
[0405] 1.5 Test Methods
[0406] The experiment was conducted on the afternoon of March 19, 2022. A backpack electric sprayer was used for spraying, with a protective cover installed. The spraying was directed at the weeds between the grape rows, and efforts were made to avoid spraying the pesticide onto the grapes. Each treatment used 30L of water per acre.
[0407] 2. Survey methods and efficacy evaluation methods
[0408] The control effects of each treatment were investigated 14 and 30 days after application. A three-point sampling method was used, with 0.5 square meters selected at each point, and the types and number of weeds were recorded. The impact on grapevines was also visually assessed.
[0409]
[0410] The survey results are shown in Table 54 below.
[0411] Table 54
[0412]
[0413]
[0414] As shown in Table 54, compared with the comparative and control agents, under low temperature conditions, the glufosinate and / or glufosinate compounded with foliar fertilizer in different embodiments of the examples showed significantly improved control efficacy against annual and perennial weeds.
[0415] As can be seen from Comparative Examples 28-30, different amounts of boron have varying synergistic effects on glufosinate, and the synergistic effect will decrease after exceeding a certain amount.
[0416] Examples 35 and 38 show that the combination of glufosinate / glufosinate with boron, urea and potassium hydrogen phthalate has the most significant synergistic effect.
[0417] Further comparison shows that the efficacy of soluble granules is not much different from that of soluble liquids, but soluble liquids are more economical than soluble granules.
[0418] The grapes in all the above treatment groups grew normally, indicating that the above-mentioned soluble granules are safe for grapes.
[0419] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
