Description
Technical Field
The invention relates to a pesticide herbicide technology, in particular to a herbicide for preventing and controlling weeds in a cold-season lawn.
Background
Fenoxaprop-p-ethyl is a selective, endotransductive herbicide mainly used for alopecurus, wild oats, chenopodium quinoa, tiger tail, large crabgrass, miscanthus, barnyard grass, cricket grass, teff grass, wild millet, duckbilled grass, moleplant seed, cluster moleplant seed, nitand grass, broomcorn millet, switch millet, cluster millet, large millet, setaria and common bluegrass. The weeds are absorbed by stem leaves and conducted to growth points of leaf bases, internode meristems and roots after being applied with the herbicide, the weeds are quickly converted into free acids of phenoxy groups, synthesis of fatty acids is inhibited, the growth points and the meristems of the weeds are damaged, the effect is quick, the weeds stop growing within 2-3 days after being applied with the herbicide, the heart leaves lose green and change purple in color after 5-7 days, the meristem is browned, then the base parts of tillers are necrotic, and the leaves gradually change purple and die.
Mesotrione is a triketone herbicide and has the advantages of wide herbicidal spectrum, low dosage, good effect and low toxicity. After the target plants are applied, the plants are conducted in xylem and phloem of the plants, generate albinism (due to degradation of chlorophyll), and then die slowly. The herbicide can prevent and kill most annual broadleaf weeds, and particularly has good weed control effect on the resistance of sulfonylurea herbicides, such as: erigeron breviscapus, siberian cocklebur, amaranth, amaranthus spinosus, black nightshade and the like.
The cold-season lawn belongs to perennial herbs, is mostly distributed in high-altitude areas of temperate zones, cold zones, subtropical zones and tropical zones, and is generally resistant to trampling and pruning. Most blades of lawn grass are small, slender, upright, low in growing point and protected by multiple layers of tough leaf sheaths, plants are bushy type, rhizome type or creeping type, the regeneration force is strong, the seed bearing amount is large, and the roots, the stems or the creeping stems are developed. The characteristics of the cold season type lawn enable the cold season type lawn to be mainly applied to places needing greening, such as parks, playgrounds, golf fields and the like in the north of China, and also to be widely applied to greening of urban squares, so that the demand is huge, and the types of the cold season type lawn are various.
In the process of planting the cold-season lawn, particularly, the influence of grassy weeds, eleusine indica with tough roots, field bindweed, clover or chickweed and other weeds causes the reproductive capacity of the cold-season lawn to be reduced, the lawn appearance effect is poor, and the weeds in the cold-season lawn are disorderly grown, so that the cold-season lawn has to be planted again. At present, special herbicides such as oxazalin, mesotrione and the like for the cold-season type lawn are mainly adopted to control weeds in the cold-season type lawn. The medicament variety has the following defects in the using process:
(1) the variety of the medicament is relatively single, and the problems of drug resistance and residue of weeds are increasingly prominent;
(2) fenoxaprop-p-ethyl has a good control effect on gramineous weeds, but has a general control effect on broadleaf weeds;
(3) the weeding spectrum of the mesotrione after compounding is wide, the effect is fast, the safety is high, but the effect of controlling broadleaf weeds mainly is poor on gramineous weeds, particularly green bristlegrass, the control effect on barnyard grass in arid plots is poor, and the using method of the mesotrione is to be studied.
Accordingly, those skilled in the art have been devoted to the development of a herbicide that overcomes the existing problems of pesticide residue and resistance.

firstly, two effective components of fenoxaprop-p-ethyl mesotrione are subjected to weeding test under the condition of room-temperature potting so as to evaluate the weeding effect of compounding the two components. According to the weeding spectrums of the two effective components, biological test objects are defined as green bristlegrass herb, chickweed, eleusine indica and Convolvulus arvensis, and the experimental objects are common weeds in cold-season lawn fields and are difficult to prevent. The specific implementation conditions are as follows:
test agents: accurately weighing 95% fenoxaprop-p-ethyl and 95% mesotrione by weight, dissolving with appropriate amount of methanol, adding into clear water containing 0.1% SOPA270 emulsifier, and stirring to obtain solution containing certain effective components.
Blank control solution: an equal amount of methanol was added to an equal amount of water containing 0.1% of the SOPA emulsifier.
The test method comprises the following steps: the activity of the compounded pesticide on green bristlegrass and chickweed is tested by a Gowing method, quantitative soil is filled in a plastic pot with the height of 7cm and the diameter of 10cm, 20 seeds of the tested weed are uniformly sown in the plastic pot, fine sandy soil with the thickness of 0.5-1cm is covered, the plastic pot is placed at room temperature (about 20 ℃) for sunlight culture, the prepared pesticide solution is compounded and diluted into pesticide liquid with a certain concentration gradient, the spraying treatment of stems and leaves is carried out when the weed grows to the 3-5 leaf stage, 1ml of pesticide liquid is sprayed in each pot, each pot is repeated for 4 times, and the pesticide liquid is diluted into a control group for comparison test. The treated test material is placed in room temperature for culture, the growth condition of weeds is observed regularly, the damage symptom and the growth inhibition condition of target weeds are observed after 21 days, the fresh weight of the plant is weighed, and the fresh weight inhibition rate (%) is calculated.
The evaluation method of the combination effect of the two is used for evaluating the combined action mode of the herbicide according to the Gowing method, and the formula is as follows:
E0(％)＝X+Y×(100-X)/100
C＝E-E0
in the formula E0The herbicide composition is a theoretical prevention effect on weed inhibition after two effective components are mixed, E is an actual measurement prevention effect on weed inhibition after the two effective components are mixed, X is the prevention effect on target weeds under the dosage of fenoxaprop-p-ethyl, Y is the prevention effect on the target weeds under the dosage of mesotrione, C is a combined action coefficient of a mixed preparation and is used for evaluating the synergistic action of the two effective components, the synergistic action is realized when the C is more than 10 percent, the antagonistic action is realized when the C is less than 10 percent, and the additive action is realized when the C is +/-10 percent.
Table 1 shows the results of the growth tests of the herbicidal activity of fenoxaprop-P-ethyl and mesotrione on green bristlegrass and chickweed at different ratios
As can be seen from the table 1, after the fenoxaprop-p-ethyl and the mesotrione are compounded, the control effect on the green bristlegrass and the chickweed is good, after the two components are compounded, the two components have obvious synergistic effect, the combined action coefficient (C) is more than 10%, and the synergistic effect after the two effective components are compounded is obvious.
Table 2 shows the results of the growth tests of herbicidal activity of fenoxaprop-p-ethyl and mesotrione on goosegrass and field bindweed in different proportions.
As can be seen from the table 2, after the fenoxaprop-p-ethyl and the mesotrione are compounded, the control effect on the eleusine indica and the field bindweed is good, after the two components are compounded, the obvious synergistic effect is achieved, and the combined action coefficient (C) is larger than 10%. The synergistic effect of the two effective components after compounding is obvious.
The two biological test experiments show that compared with the effect of a single medicament, the compound of fenoxaprop-p-ethyl and mesotrione has good synergistic effect on the control effect of green bristlegrass, goosegrass, chickweed and Convolvulus arvensis.
Example 11
The following tests are performed to detect the weeding effects of the herbicides with different proportions of fenoxaprop-p-ethyl and mesotrione obtained in the embodiments 1-9, and the control effects of the embodiments are determined by comparison with a single fenoxaprop-p-ethyl and a single mesotrione as a control group test and with clear water as a blank control group test, and the specific test modes are as follows:
the herbicide obtained in the examples 1 to 9 is respectively used for field efficacy experiments for preventing and controlling green bristlegrass, chickweed, goosegrass and field bindweed in the cold season type lawn direct seeding field, the experiment places are Zhengzhou and Jiangsu Nanjing in Henan, the time is 4 months and 20 days in 2018, the cold season lawn is in the 2-4 leaf stage and the weed 2-5 leaf stage, the medicament obtained in the examples 1 to 9 is taken to be tested in the cold season type lawn field, a comparison test is carried out by 40 percent fenoxaprop-P-ethyl water dispersible granules and 30 percent mesotrione suspending agent, twelve treatments are carried out in the test, each treatment is carried out in three times, the test areas are randomly arranged, and the area of each treatment is 25m2. The agents of examples 1 to 9 and the control group were sprayed to the stem and leaf of each test area once, and the plant control effect of each agent was observed 15 days and 30 days after application. Visual test shows that the agent has no phytotoxicity to the cold-season lawn.
The control effect is calculated according to the following formula:
the test results are as follows:
table 3 shows the results of the efficacy tests of fenoxaprop-p-ethyl and mesotrione in different proportions for controlling cold-season lawn weeds
From the data, the compound preparation of fenoxaprop-p-ethyl and mesotrione has the control effect of over 85 percent on the common weeds in cold-season lawn fields such as green bristlegrass, chickweed, goosegrass, Convolvulus arvensis and Convolvulus arvensis for 15 days and 30 days, and has very obvious synergistic effect compared with single dose of fenoxaprop-p-ethyl and mesotrione. Meanwhile, after the two components are compounded, the compound preparation has good control effect on both gramineous weeds and broadleaf weeds, and compared with a single agent, the weeding spectrum is expanded. The dosage range used in the experiment is safe for the cold-season lawn.
In conclusion, after the two components of fenoxaprop-p-ethyl and mesotrione are compounded, the weeding effect on field weeds is far higher than that of two single agents, after the two components are compounded, the synergistic effect is obvious, the weeding spectrum is expanded, the pesticide application times of farmers are reduced, the labor capacity of the farmers is reduced, and the economic benefit is improved.
