Description

Tree-removing and irrigation-killing agent composition and application thereof
Technical Field
The invention belongs to the technical field of prevention and control of pesticides and harmful plants, and particularly relates to a tree-removing and irrigation-killing agent composition containing hexazinone, pyridyloxycarboxylic acid components and sulfonylurea components and application thereof.
Background
The arbor and shrub plants planted in specific occasions are plants for greening and beautifying the environment, but in non-cultivated land occasions such as railways, highways, airports, electric power, telecommunications, storage, industrial and mining enterprises, forestry and the like, because of less intervention, some arbors and shrubs grow in unsuitable areas and grow arbitrarily, the appearance is influenced, and the safety and normal operation and maintenance of corresponding occasions are greatly threatened, so that the arbor and shrub mixed irrigation is realized. For example, railway signal lamps and road warning boards are shielded, and the driving safety is threatened; the photovoltaic panel is shielded to form a hot spot effect, so that the power generation efficiency is influenced; the problem that the maintenance work in the non-cultivated land places is troublesome is that the power access is invaded, the approach maintenance construction of maintenance workers is hindered, the harmfulness is high, the prevention and control difficulty is high. To solve the above problems, these non-cultivated land fields are mainly controlled by the following methods:
(1) And (5) manual felling. Related non-cultivated land operation and maintenance departments such as a railway engineering system and the like organize a large amount of manpower to repeatedly cut and trim the miscellaneous tree irrigation which invades a target area every year, although the mode is effective at that time, the effect is very little, not only is labor and time consumed, but also because the miscellaneous tree irrigation is in a relatively spacious growth condition, the growth capacity is very strong, and new branches can be quickly germinated on cut tree piles. In summer with sufficient sunlight and abundant rainwater, and a large number of unclosed seeds in soil germinate, the seeds are usually excessively grown and more dense after being artificially felled, and the seeds are threatened again after invading a safe area, even the situation of 'more and more felled' is formed. Particularly, after the shrub seeds are mature in railway occasions, the shrub seeds are scattered irregularly on the slope and the road shoulders and can germinate and grow naturally, the shrub seeds grow longer and denser along with succession of vegetation on the slope, overgrowth can occur after a few years of planting, even the shrub seeds spread to the road shoulders of the railway to form 'dangerous trees', the landscape effect is reduced, the advancing and daily road protection operation of railway maintenance personnel can be influenced, the sight of a train driver is even shielded, railway electric facilities and the like are influenced, the normal running of the train is hindered, and the running safety and the convenient construction are seriously threatened. In non-cultivated land occasions with long internal range and wide area, such as railways, roads, photovoltaic power stations and the like, manual felling cannot be done at all, repeated felling workers have high labor intensity and low working efficiency, and the labor cost is higher. In addition, the lateral branches of the main stems of the albizia julibrissin, the robinia pseudoacacia, the wild jujube and the like have thorns, and the main stems have the risk of scratching the skin without leaving spirit in the cutting process.
(2) Herbicides (such as glyphosate) are used for control. In the face of the above situation, some operation and maintenance departments try to adopt herbicides to treat the herbicide chemically, so that the efficiency is improved to a certain extent. However, the method is limited by the type of the product and the technical defects, and the ideal effect of preventing and controlling the mixed irrigation of the mixed trees is often difficult to achieve, or the method of use or the dosage of the medicament is improper, so that other greening plants or farmland crops outside the control area are damaged. The prevention and control requirements of the non-cultivated land occasion on the mixed irrigation of the mixed trees are difficult to meet. For example, glyphosate and other herbicides are adopted for preventing and killing in many places, glyphosate belongs to systemic conductive herbicides, has a good effect on killing weeds, and has weak preventing and killing capacity on woody plants such as trees, shrubs and the like; and after entering the soil, the fertilizer is passivated, the lasting period is too short, and the fertilizer does not have the function of sealing seed germination. This makes the work of removing trees and killing irrigation have to be repeated, and is very labor-consuming and time-consuming, and the mu dosage of using glyphosate is more and more. Then, the single-component non-farmland weeding and irrigating agent represented by triclopyr and the like is used, the control effect on the mixed irrigation of the hybrid trees is improved, and the times of spraying construction every year are reduced. However, the variety of the non-cultivated land miscellaneous tree irrigation is complex, various miscellaneous tree irrigation such as leguminous (such as amorpha fruticosa, albizzia julibrissin and the like), moraceae (such as broussonetia papyrifera), verbenaceae (such as schizonepeta twig) and Sapindaceae (such as goldenrain tree) are mixed, and the single-component preparation is used independently and shows certain defects and limitations. And the single components are used for a long time in a large area, the problem of the drug resistance of the mixed irrigation of the mixed trees is more and more prominent, and the effect is more and more poor. The commonly adopted coping mode is to continuously increase the dosage and the use frequency. By doing so, the total amount of the medicament used is increased, the purchasing cost is increased, and even the influence on peripheral greening plants and crops is generated, and the problem is not solved fundamentally.
Therefore, a new formula is further researched and explored, a compound tree-removing irrigation-killing agent capable of effectively preventing and removing the mixed tree irrigation in the non-cultivated land and application thereof are developed, the prevention and removal effect is improved, the prevention and removal spectrum is expanded, the prevention and removal effect on the resistant mixed tree irrigation is especially improved, and the medication frequency is further reduced and the construction efficiency is improved.

The technical scheme of the invention is based on the technical principle of pesticide compounding, refers to the application effects of different components, and screens several components to make up for deficiencies according to the principle of effect complementation. And the tree-removing and irrigation-killing agent composition is processed by reasonable concentration proportion combination and a specific process.
The following examples are intended to further illustrate the invention but should not be construed as limiting it. Modifications and substitutions may be made thereto without departing from the spirit and scope of the invention.
Unless otherwise specified, the technical means used in the examples are conventional means well known to those skilled in the art, and unless otherwise specified, the reagents used in the present invention are analytically pure or above.
Examples 1 to 12
Selecting the types of main resistant miscellaneous tree and miscellaneous irrigation such as amorpha fruticosa, paper mulberry, chaste tree, goldenrain tree and the like which are difficult to effectively prevent and remove in the field of non-cultivated land as test objects, wherein the application time is spring, the test places are non-cultivated land sections belonging to Toftai West workshops and Tongzhou forest workshops under the Beijing railway administration, and the prevention and removal effects of the compositions of components such as hexazinone, triclopyr, sulfometuron and the like and the single components of the comparative examples on the non-cultivated land miscellaneous irrigation are researched according to different weight parts.
Examples 1 to 12 are compositions containing two or more of hexazinone, triclopyr and sulfometuron-methyl as effective components, and the proportion of each effective component is different; comparative examples 1 to 3 are single-component preparations each containing one of 3 kinds of effective ingredients such as hexazinone, triclopyr, sulfometuron-methyl and the like, and comparative example 4 is a single-component preparation of glyphosate. An equivalent amount of water without any active ingredient added was used as a blank.
The method for preparing the tree-removing and irrigation-killing agent in the embodiments 1-12 comprises the following steps: (1) according to the raw materials and the parts by weight thereof shown in Table 1, three effective components are respectively weighed: hexazinone, triclopyr, sulfometuron-methyl, and auxiliary agents such as tea saponin (wetting agent), sodium lignosulfonate (dispersing agent), xanthan gum (thickening agent), dimethyl silicone oil (defoaming agent), calcium dodecyl benzene sulfonate (emulsifier), polyethylene glycol (anti-freezing agent), sodium benzoate (preservative) and sodium bicarbonate (stabilizer); (2) adding the two effective components of the hexazinone and the sulfometuron-methyl, a wetting agent, a dispersing agent, a thickening agent, a defoaming agent and the like into a sand mill by taking carrier water as a medium, and fully grinding to ensure that the particle size D90 of the liquid medicine is below 10 mu m to prepare a suspending agent; (3) and (3) adding triclopyr, an emulsifier, a dispersant, a thickening agent, an antifreezing agent, a preservative, a stabilizer and the suspending agent prepared in the step (2) into a shearing kettle, mixing, adding the balance of carrier water to 700 parts, and shearing at high speed in the shearing kettle to enable the particle size D90 of the liquid medicine to be below 5 mu m to prepare the suspension emulsion.
In order to control single variables of the test, the additives added in examples 1-12 are exemplified by 20 parts of tea saponin (wetting agent), 30 parts of sodium lignosulfonate (dispersant), 3 parts of xanthan gum (thickener), 1.5 parts of dimethicone (defoamer), 40 parts of calcium dodecylbenzenesulfonate (emulsifier), 35 parts of polyethylene glycol (antifreeze), 3 parts of sodium benzoate (preservative), 6 parts of sodium bicarbonate (stabilizer), and purified water added to total weight of 700 parts (wherein, the blank control is prepared by adding only the above additives and purified water to total weight of 700 parts without adding any effective components).
Comparative examples 1-4 are commercially available single-component formulations of the above three ingredients and glyphosate, namely, commercially available 25% hexazinone solution, 480g/L triclopyr emulsifiable concentrate, 10% sulfometuron-methyl suspension, and 41% glyphosate isopropylamine salt aqueous solution (see table 2).

Table 2: each proportional corresponding component
Figure BDA0003833727150000081
Each treatment of each of the examples and comparative examples was repeated 4 times, and each cell was sampled at 100m 2 Random block permutation. Except that different component proportions are applied according to the scheme, other conditions of each treatment area are completely the same; the growth conditions of plants to be treated in the area are basically consistent. The application method is carried out by spraying in a shoulder type spray can, and the spraying amount is 100m 2 The dosage of the effective components (the actual dosage of the corresponding components of the hexazinone, the triclopyr or the sulfometuron-methyl) is 20.7g (the dosage of the effective components is 138 g/mu in terms of mu), and in order to ensure the uniform spraying and control the single variable of the test, each treatment is carried out by diluting the total effective components by 200 times for example when in use, namely, each treatment is carried out every 100m 2 The amount of the diluted solution was 4.14kg. Observing and measuring in three times 30 days, 90 days and 180 days after spraying the tree-removing and irrigating agent preparation, investigating and recording the tree-removing and irrigating-preventing rate of the treated area, randomly sampling 5 points in each area during investigation, and sampling the area of 10m 2 The control effects of the respective examples and comparative examples on weed control are shown in Table 3. The control effect of the mixed tree and the mixed irrigation in the table is calculated according to the control effect of the plants. Namely, the mixed tree and mixed irrigation control ratio% = (the number of mixed tree and mixed irrigation plants normally growing in the blank control area-the number of mixed tree and mixed irrigation plants living in the treatment area)/the number of mixed tree and mixed irrigation plants normally growing in the blank control area x 100%.

Figure BDA0003833727150000082
Figure BDA0003833727150000091
As can be seen from the above table: it is found by comparing examples 1 to 12 that example 11 has the best comprehensive tree-removing and irrigation-killing effect at each period, and the content ratio of each component of example 11 is the best combination.
As can be seen from comparison of examples 1-12 with comparative examples 1-4, the control rate of the mixed tree and weed irrigation by using the compound mixture is obviously improved and the synergistic or additive effect is shown compared with that of each single agent.
As can be seen by comparing the control effects of the hybrid tree and the hybrid irrigation for 30 days in the examples 1 to 6, the increase of the content of the triclopyr and the hexazinone has obvious effect on improving the quick action of the composition; from the effect of 180 days, the increase of the content of the sulfometuron-methyl has a certain effect on improving the weed-tree weed-irrigation control effect of 180 days, namely prolonging the effective period, and the addition of the hexazinone has a further enhanced effect on promoting the long-term control effect of 180 days.
The effect of 30 days in examples 7-9 shows that, without the addition of sulfometuron-methyl, the rapid effect cannot be continuously and remarkably increased by simply increasing the content of triclopyr or hexazinone, and when the hexazinone and triclopyr are reasonably mixed, the rapid effect can be better achieved.
As can be seen from the 90-day effects of examples 1-9, the best effect is achieved when two of the three active ingredients are combined in pairs and the two components are in proper balance proportion, and each treatment achieves better effect in 90 days.
As can be seen from examples 1-12 and comparative examples 1-4, the control effect of each single-component preparation is general, certain defects and limitations exist, and particularly the control effect of the common component glyphosate (comparative example 4) is weak after 90 days; after the three components are compounded and combined, the control effect is greatly increased in each period and reaches the optimum under the proper proportion.
The three effective components have the functions of mutual supplement and coordination promotion, the reduction of one or two of the three effective components can obviously reduce the weed irrigation control effect of the hybrid trees, and the optimal control effect is achieved only when the three effective components are compounded and combined at the same time.
In addition, the control effect conditions of the compound type tree removing and irrigating agent composition disclosed by the invention on 30 days and 180 days are compared with other examples and comparative examples in the cases of 30 days and 180 days, and the control effect of the compound type tree removing and irrigating agent composition disclosed by the invention on the mixed tree and irrigating is greatly improved, so that the compound type tree removing and irrigating agent composition disclosed by the invention has obvious effects on improving the action speed of preventing the mixed tree and irrigating and prolonging the lasting period of the tree removing and irrigating.
Example 13
In order to further verify whether the most preferred compound tree-removing and irrigation-killing composition (example 11) generates a synergistic effect or a synergistic addition effect in the aspect of preventing and controlling non-cultivated land miscellaneous tree irrigation, and the synergistic effect of other combinations with different dosage ratios under the same three components and the synergistic effect of binary compound treatment of each effective component under the corresponding dosage ratio, the amorpha fruticosa and the morus multicaulis trees of leguminosae of typical resistant miscellaneous tree irrigation on non-cultivated land are selected as test targets, and relevant tests are set. The specific test implementation is as follows:
test agents: sequentially weighing 0.2403g, 0.6008g and 0.9612g of 98% hexazinone raw drug by using an electronic balance (induction amount is 0.1 mg), respectively adding 5ml of acetone, fully dissolving, diluting to a constant volume of 500ml by using a tween-80 aqueous solution containing 0.1% by volume, and sequentially preparing 300g.a.i./hm of hexazinone 2 、750g.a.i./hm 2 、1200g.a.i./hm 2 A solution; 0.2822g, 0.5709g and 0.8564g of 99% triclopyr technical material are sequentially weighed, 5ml of acetone is respectively added to be fully dissolved, and then Tween-80 aqueous solution with the volume ratio of 0.1% is used for diluting to the constant volume of 500ml, so that 360g.a.i./hm2 and 720g.a.i./hm of triclopyr are sequentially prepared 2 、1080g.a.i./hm 2 A solution; 0.2479g, 0.4958g and 0.7437g of 95% sulfometuron-methyl technical are weighed in sequence, and 5ml of acetone is respectively added fullyAfter dissolving, using Tween-80 aqueous solution with volume ratio of 0.1%, diluting to constant volume to 500ml, and preparing to obtain the sulfometuron-methyl 300g.a.i./hm 2 、600g.a.i./hm 2 、900g.a.i./hm 2 The solution (the above effective component dosage is converted according to the effective component dosage used when 2ml of the chemical solution is sprayed on the land area with the diameter of 20cm in the plastic bowl). According to the single-agent preparation method or by using the single-agent solution as the mother solution of the treatment group, a series of ratios are set according to the mixing purpose, and the following treatments are set together (no active ingredient is added to the blank control, namely only 5ml of acetone is added, and 0.1% Tween-80 aqueous solution is used for fixing the volume to 500ml of the solution to be used as the mother solution of the blank control treatment), wherein the details of each treatment are shown in the following tables 4 and 5 (wherein the treatment 2, the treatment 5, the treatment 8 and the treatment 23 in the tables 4 and 5 are common treatment, and the treatment 37, the treatment 38 and the treatment 39 are binary compound combinations which are most preferably combined with the corresponding component ratios).

Test soil: adopting non-cultivated land surface soil with neutral pH value and good permeability, naturally drying, sieving, and quantitatively loading to a pot 4/5.
And (3) culturing test materials: the method comprises the steps of respectively layering and accelerating germination of the hybrid irrigation seeds (amorpha fruticosa and paper mulberry trees) of the target trees for testing, which are produced in non-cultivated land occasions, and sowing after the seeds are exposed to white. The pre-treated test seeds are uniformly and quantitatively sowed in soil in pots according to 10 grains per pot, the soil is covered by 0.5-1.0 cm, the test seeds are put into a tray filled with water, the water is gradually infiltrated from the bottom, and the test seeds are moved into a culture chamber for culture after the water is infiltrated to the soil surface.
Medicament treatment: and (3) carrying out stem leaf spraying treatment by using a Potter spraying tower when the seedlings of the hybrid tree and the irrigation plant grow to 2-3 leaves, spraying 2ml of liquid for each pot, repeating the treatment for 4 times, setting the treatment without the medicament as a blank control, and culturing the treated test material in a culture chamber.
The investigation method comprises the following steps: and after treatment, regularly observing and recording the growth state of the target, describing the damage symptoms of the plant seedlings, investigating and recording the activity of the medicament according to a growth inhibition method 35 days after treatment, and weighing the fresh weight of the hybrid tree hybrid irrigation seedlings.
The data statistical method comprises the following steps: the fresh weight control effect (fresh weight inhibition ratio) of each treatment was calculated in percentage (%) according to the formula based on the survey data.
Reference absolute value method: actual fresh weight control effect E (%) = (fresh weight of mixed tree and irrigated seedlings in control area-fresh weight of mixed tree and irrigated seedlings in treatment area)/fresh weight of mixed tree and irrigated seedlings in control area x 100%
Reference to Colby method: taking the mixed use of three medicaments A, B and C as an example, the theoretical fresh weight inhibition effect of the mixed use according to the proportion is calculated according to a formula: e 0 (%) = a + B + C +... N = inhibitory effect of agent 1 + inhibitory effect of agent 2+ inhibitory effect of agent 3 + inhibitory effect of agent N.
Wherein, A, B, C and/or A.t.. N respectively represent the actual fresh weight inhibition effect of a single medicament such as the medicament 1, the medicament 2, the medicament 3 and/or the.t.. Medicament N, and N is the number of varieties of mixed medicaments. E-E 0 >10% is synergistic effect; E-E 0 <-10% is antagonism; E-E 0 Values within. + -. 10% are additive effects. The results of the treatments are shown in tables 6 and 7 below.
TABLE 6 fresh weight inhibition effect data statistics table (1)

Figure BDA0003833727150000141
Figure BDA0003833727150000151
As can be seen from Table 6, when the three components of hexazinone, triclopyr and sulfometuron are used in combination, all the proportions show synergistic or additive effects, wherein the E-E under the proportion dosage of 23 (A2 + B2+ C2) is treated 0 The values are all significantly larger than other combinations, namely hexazinone, triclopyr and sulfometuron-methyl 750 +600 (g.a.i./hm) 2 ) The synergistic effect of the compound combination treatment on the control effect of amorpha fruticosa and broussonetia papyrifera is most obvious, and E-E thereof 0 The values were 15.8% and 18.6%, respectively.
TABLE 7 fresh weight inhibition effect data statistics table (2)
Figure BDA0003833727150000152
From the statistical results in table 7, the most preferable combination treatment of three components, namely hexazinone, triclopyr and sulfometuron (treatment 23): the dosage of hexazinone + trichloropyrifthoxyacetic acid + sulfometuron-methyl is 750+720+600 (g.a.i./hm) 2 ) Namely, 50 parts of hexazinone, 48 parts of triclopyr and 40 parts of sulfometuron-methyl have the inhibiting effect on amorpha fruticosa and broussonetia papyrifera of leguminosae 0 The (%), values are all more than 10%, which shows that the most preferable compound treatment of the three components has obvious synergistic effect compared with single agent. Any two of the three corresponding components are mutually compounded and combined under the dosage ratio to form three groups of treatments (treatments 37-39): one group of the compositions shows addition effect, and the two groups (treatment 37 and treatment 39) show synergistic effect, but the E-E0 value (%) of the compositions is obviously smaller than that of the corresponding treatment of compounding three components. The most preferable combination treatment of the three components is obviously superior to the combination (binary combination) treatment of the two corresponding components in the synergistic effect.
