Description
Technical Field
The invention belongs to the technical field of pesticide preparation, and particularly relates to a herbicide composition and application thereof.
Background
The weeds grow in non-cultivated land places such as railways, highways, airports, telecommunications, warehouses, industrial and mining enterprises and forestry, the appearance is influenced, signals are easily shielded, and a fire disaster is caused or the weeds become intermediate hosts of certain plant diseases and insect pests or overwintering places, so that certain harm is brought to the operation, production and the like of the non-cultivated land places.
Weeds in non-cultivated land occasions are always the problem which is difficult to solve in the fields of industrial production, transportation and the like. The most common methods rely on manual use of a mower to cut grass or a knife to cut a hand. In places where chemical weeding is conditionally performed, a single ingredient such as glyphosate or sulfometuron-methyl is often used for weeding.
At present, weeding methods in the field of non-cultivated land are mainly divided into two modes, one mode is manual weeding, the method generally adopts manual spade shovels to pull out by hands or uses a mower to weed, but manual weeding is difficult to cut weeds and remove roots, and the situation that weeds are repeated and are not living is formed; in summer with sufficient sunlight and abundant rainwater, if weed seeds are not sealed by herbicide, small weeds can grow around one week after artificial weeding, the weeds can grow to dozens of centimeters in half a month, and some weed varieties even can reach more than one meter, so that the situation forms 'grass shortage'! On the other hand, in non-cultivated land occasions with long internal range and wide area, such as railways, highways, photovoltaic power stations and the like, artificial weeding cannot be performed at all, and labor cost caused by repeated weeding is higher.
Another way is to use chemical control method. Generally, a single herbicide component such as glyphosate, sulfometuron-methyl and the like is used. As a very common systemic conduction type herbicide, glyphosate can weed and remove roots of weeds, but has a short duration, cannot play a role in sealing weed seeds, and can still grow the succeeding weeds quickly, thus consuming labor at the same time. And because of the long-term use of a large amount of glyphosate, a large number of weeds generate resistance to the glyphosate, so that the weeding effect is reduced. The sulfometuron-methyl serving as a non-cultivated land herbicide is widely used in non-cultivated land occasions in recent years, although the effect is remarkable, the single component not only has slow effect, but also has a great deal of weeds generating drug resistance to the herbicide after long-term use, the weeding effect is poor, and the weeding effect is more and less for preventing and killing part of ferns and shrubs by weed irrigation. Therefore, the commonly adopted coping mode is to continuously increase the dosage and the use frequency, thereby increasing the investment, even having high risk of phytotoxicity to crops, and not really solving the problem.

Detailed Description
The following examples serve to further illustrate the invention, but the invention is by no means limited to these examples. The following examples, which are only some of the present invention, are provided for the purpose of illustration only and should not be construed as limiting the invention. 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.
Examples 1 to 7
Selecting common resistant weeds including reed, goosegrass herb, ragweed and purslane in non-cultivated land occasions, fern weeds including field horsetail and oleander which are difficult to prevent and remove by the existing herbicides as test objects, configuring imazapic, glyphosate, methoxone and sulfometuron-methyl according to different weight proportions, configuring herbicide compositions according to table 1, and researching the preventing and removing effects of various concentration combinations and comparative example single agents on the weeds. A method of formulating a herbicidal composition: weighing herbicide raw materials according to the use amounts of the components in the table 1; melting the raw material herbicide, crushing into fine powder and sieving for later use; and thirdly, adding an auxiliary agent and water into the fine powder obtained in the step II, supplementing the fine powder to 1000 parts by weight of water, and fully stirring to obtain uniform milky white suspension, wherein the water is clear water. Fourthly, the herbicide in the step II is prepared into any acceptable dosage form in the market, such as water aqua and water emulsion, by adopting a micro-diameter grinding technology and adding an auxiliary agent acceptable in the pesticide processing field and adopting the traditional processAgents, suspending agents, wettable powder, water dispersible granules and the like. In the embodiment, the preferable suspending agent can be added with one or more additives selected from wetting agents, dispersing agents, thickening agents, defoaming agents, antifreezing agents, stabilizing agents, water and the like. The additives added in examples 1-7 and comparative examples 1-4 are fatty alcohol-polyoxyethylene ether 20 parts (wetting agent), sodium lignosulfonate 30 parts (dispersing agent), xanthan gum 5 parts (thickening agent), dimethyl siloxane 2 parts (defoaming agent), ethylene glycol 50 parts (antifreezing agent), dodecylbenzene sulfonic acid 10 parts (stabilizing agent), and clear water to total weight 1000 parts (wherein, in example 7, no active ingredient is added, only the additive and clear water are added to total weight 1000 parts as a blank control). Each treatment was repeated 4 times, with 25m samples per cell2Random block permutation. The conditions were identical for each treatment area except that the herbicide was applied according to the above protocol. Observing in three times 7 days, 45 days and 90 days after spraying herbicide, respectively, identifying and counting weeds in the treated area, randomly sampling 4 points in each plot during investigation, and measuring the area of the sample prescription to be 0.25m2The corresponding herbicidal effects are detailed in table 2.
Table 1 examples each component part by weight
Table 2: statistical table of weeding effect of each component
The weeding effect in the table above is statistically calculated according to the control effect of the plants, namely: the weed control rate is (number of weed plants in the control area-number of weed plants in the treatment area)/number of weed plants in the control area multiplied by 100%.
As can be seen from Table 2 above, it was found by comparative examples 1 to 7 that the overall herbicidal effect of example 5 was the most excellent and the content ratio of the components of example 5 was the optimum combination.
As can be seen from the comparison of examples 1-6 with comparative examples 1-4, the herbicidal rate of the compounded mixture is significantly improved and the synergistic effect is exhibited as compared with that of each single agent. The compounded weed control spectrum is expanded, and resistant weeds such as gramineous reed, eleusine indica, broadleaf ragweed, purslane and the like are effectively prevented and killed; and surprisingly, the pesticide also has obvious control effect on fern weed horsetail and shrub mixed oleander which are difficult to control by using the existing single agent.
As can be seen by comparing the observation effects of the two components in examples 1 to 3 for 7 days, the high contents of the methoxone and the glyphosate have a remarkable effect of increasing the weed control speed of the herbicidal composition; the results of 45 days and 90 days of observation show that the weed killing effect is not obviously increased by simply increasing the amount of the sulfometuron-methyl on the premise of not adding the imazalil component, and the purslane with tolerance to the sulfometuron-methyl has an obvious green turning condition in the observation period of 90 days.
In the examples 4-6, due to the addition of the imazapic component, the situation that reeds, goosegrass, ragweed, purslane, field horsetail and oleander have no obvious relapse in the observation period of 90 days, so the imazapic mixed with the components of methoxone, glyphosate and sulfometuron can obviously solve the problem of weeds with resistance to sulfometuron-methyl.
In addition, the weeding conditions of 7 days and 90 days are observed to show that the control effects of the herbicide in 7 days and 90 days are greatly improved, which shows that the composite formula weeding composition has obvious effects on improving the weeding effect speed and effectively prolonging the weeding effective period, thereby reducing the application times and saving manpower and material resources.
Example 8 (indoor bioactivity test)
In order to further verify the weeding effects of the preferable herbicide composition and different mixed combinations thereof and evaluate whether the preferable herbicide composition generates a synergistic effect or a synergistic addition effect in the aspect of preventing and controlling non-cultivated land weeds, the composition proportion dose pairs of four single agents of imazapic, glyphosate, methoxone and sulfometuron, two single agents of the four single agents, three single agents of the four single agents, the three single agents, the four single agents, the three single agents, the four single agents, the two single agents, the. The specific test implementation is as follows:

Table 3: dosage table for each treatment agent
A method for treating stem and leaf of potted plant is carried out by taking surface soil of non-cultivated land with neutral pH value and good permeability, quantitatively loading into plastic pots (about 4/5) with diameter of 50cm, soaking weed seeds (eleusine indica and ragweed) as test targets, germinating, and sowing after seeds are exposed. Uniformly and quantitatively sowing the pretreated weed seeds to be tested into soil in each pot according to 20 grains, covering soil for 0.5-1.0 cm, and then transferring into a greenhouse for culture. And (3) carrying out stem and leaf spraying treatment when the weeds grow to 3-5 leaves, spraying 2ml of pesticide liquid in each pot, repeating the treatment for 4 times, setting the treatment without the pesticide as a blank control, and culturing the treated test material in a greenhouse. And after treatment, the growth state of the target weeds is regularly observed and recorded, the weed damage symptoms are described, the weeding activity is investigated and recorded 25 days later according to a growth inhibition method, and the fresh weight of the overground parts of the weeds or the fresh weight of the whole plants is weighed.
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.
Absolute value method: fresh weight control effect E (%) - (fresh weight of weeds in control area-fresh weight of weeds in treated area)/fresh weight of weeds in control area X100%
The Colby method: taking A, B, C three kinds of medicine as an example, the theoretical fresh weight control effect of the mixed use according to the proportion is calculated according to the formula: e0A.. N.. the control of herbicide 1 + the control of herbicide 2 + the control of herbicide 3.. the control of herbicide N.
Wherein, the intermediate A, B, C and the intermediate N respectively represent the actual fresh weight control effect of a single herbicide such as a herbicide 1, a herbicide 2, a herbicide 3 and the like, and N is the number of varieties of mixed herbicides. E-E0>10% of the composition is synergistic effect; E-E0<-10% is antagonism; E-E0Values within. + -. 10% are additive effects. The results of the treatments are shown in Table 4 below.
Table 4: fresh weight control effect data statistical table
As can be seen from Table 3, the E-E of the fresh weight control effect of the imidazole niacin, the glyphosate, the methoxone and the sulfometuron-methyl (treatment 15) on the eleusine indica and the ragweed0The values of percent are all larger than 10 percent, which shows that the four-component compound has obvious synergistic effect compared with a single agent. Two and three of the four components are compounded with each other to form ten groups of composition treatments (treatments 5-14), wherein seven groups of the compositions showAddition, only three groups showed synergistic effect, but E-E thereof0The values (%) are all significantly less than the treatment of compounding the four ingredients. The synergistic effect of the four-component compounding treatment is obviously superior to that of two or three components (binary and ternary compounding).
