Description

Medicament for removing flying cotton and fly of plants and application thereof
Technical Field
The invention relates to the technical field of plant flying cotton fly removal, in particular to a medicament for removing plant flying cotton fly and application thereof.
Background
The flying catkin of plants such as poplar, willow and the like is an attachment of seeds of plants such as poplar, willow and the like, and the flying catkin can fly with wind to play a role in helping seeds to spread and disperse, so that the flying catkin pollution is caused. The harm is mainly reflected in three aspects: firstly, the flying cotton fibers are easy to wrap harmful substances such as pollutant particles, heavy metals and the like, and are easy to cause discomfort and even inflammation after contacting with the skin of citizens, so that skin allergy of allergic people is caused; meanwhile, the catkins are easy to be inhaled into nostrils, so that respiratory diseases such as asthma, chronic bronchitis and the like are aggravated, and the health of citizens is damaged. Secondly, the flying wadding often blocks the radiator fin of the automobile water tank to cause the boiling pot to extinguish, and can also shield the sight of pedestrians and vehicles, thereby causing influence on traffic safety and public safety. Thirdly, the flying wadding is easy to cause fire when contacting open fire, thereby bringing hidden danger to public safety. Therefore, the flying-floc problem of plants such as salix populi becomes a focus and a hot point of social attention, and concerns the vital interests of people, and the public has high call for the control of the flying-floc of salix populi.
The sycamore is an important street tree species in south China, is widely planted in north, is heavily shaded and has a tall plant shape, but a large amount of fruit hairs can be scattered every year in the fruit drop period of the sycamore, and serious influence is caused on the environment and human health. According to statistics, the mean of 200-.
Therefore, the search for a chemical or method capable of preventing flying cotton wool of plants such as poplar, willow and tabebuia avellanedae is a problem to be solved by those skilled in the art.
Disclosure of Invention
Aiming at the defects in the prior art, the first purpose of the invention is to provide a medicament for thinning plant catkin fly hair, which can inhibit the growth and development of flower buds of plants such as poplar, willow, plane.
The first purpose of the invention is realized by the following technical scheme:
a medicament for thinning plant flying cotton and fly comprises the following raw medicines in parts by weight: the plant growth regulator comprises one or more of forchlorfenuron, 6-benzyladenine, paclobutrazol, uniconazole, 2, 4-dichlorophenoxyacetic acid, triiodobenzoic acid, 2-chloroethyltrimethylammonium chloride and cycloheximide, the plant fruit thinning agent comprises one or more of indate and chlorpropham, and the herbicide comprises one or more of sulfonylurea herbicides, imidazolinone herbicides and triazolopyrimidine herbicides.
By adopting the technical scheme, the forchlorfenuron (3-isopropyl chlorocarbamate) is a phenylurea plant growth regulator with cytokinin activity, has the biological activity 10-100 times higher than that of 6-benzylaminopurine, is widely applied to agriculture, horticulture and fruit trees, promotes cell division and promotes cell expansion and elongation. 6-benzyladenine (6-benzzylaminopurine) and forchlorfenuron (1- (2-chloro-4-pyridine) -3-phenylurea) belong to plant growth regulators with the same effect. The naphthylacetic acid (1-naphthylacetic acid) is applied to flower production, can promote flower growth, control plant type, induce flowering and fruiting, prevent flowering diseases and prevent falling, and can also obviously improve planting benefits. Paclobutrazol ((2RS, 3RS) -1- (4-chlorphenyl) -4, 4-dimethyl-2- (1H-1, 2, 4-triazole-1-yl) pentan-3-ol) is a plant growth regulator, and has the effects of delaying plant growth, inhibiting stem elongation, shortening internode, promoting plant tillering and increasing plant stress resistance. Uniconazole ((E) - (RS) -1- (4-chlorphenyl) -4, 4-dimethyl-2- (1H-2, 4-triazole-1-yl) pent-1-en-3-ol) belongs to a broad-spectrum and high-efficiency plant growth regulator, has the effects of controlling vegetative growth, inhibiting cell elongation, shortening internodes, dwarfing plants, promoting lateral bud growth and flower bud formation and enhancing stress resistance, has the activity 6-10 times higher than that of the uniconazole, but has the residue of 1/10 of the paclobutrazol in soil. 2, 4-Dichlorophenoxyacetic acid is a representative synthetic auxin (auxin), an auxin analog, 2, 4-D for short. Triiodobenzoic acid, 2-chloroethyl trimethyl ammonium chloride and cycloheximide (3- [2- (3, 5-dimethyl-2-oxocyclohexyl) -2-hydroxyethyl ] glutarimide) all belong to anti-auxin, prevent the polar transportation of auxin in plants from top to bottom, are easy to be absorbed by plants, can be transported in stems, influence the growth and development of the plants, inhibit the top growth of the plants, dwarf the plants and promote the growth of lateral buds and tillers. The indole ester (ethyl-5-chloro-1 hydro-3-indolylacetic acid) and the chlorpropham (3-chloroisopropyl carbamate) are vegetable and fruit agents, belong to auxin inhibitory substances and can obtain expected effects by inhibiting the growth of plant organs. Sulfonylurea herbicides, imidazolinone herbicides and triazolopyrimidine herbicides all belong to ALS inhibitors, which disrupt the synthesis of valine, leucine and isoleucine in plants by inhibiting the ALS enzyme (acetolactescence synthase), and are safe to humans and animals since this target is not involved. The ALS enzyme, also known as acetohydroxy acid synthetase (AHAS), is a key enzyme in branched chain amino acid synthesis; catalyzing two molecules of pyruvic acid to generate acetolactate and carbon dioxide in the synthesis of valine and leucine, and catalyzing one molecule of pyruvic acid and one molecule of ketobutyric acid to generate 2-glyoxal-2-hydroxybutyric acid and carbon dioxide in the synthesis of isoleucine; biochemistry, genetics and field practice have proven to be an important herbicide target; if the ALS enzyme activity is inhibited, the synthesis of branched chain amino acid is hindered, and the protein synthesis and the plant growth are further influenced; during the growth of plants, flower organs require more ALS activity than the vegetative organs of plants, i.e. flower organs are more sensitive to low doses of ALS inhibitors, so that this type of agent has an effect on the flower organs of plants only in a certain dosage range and does not cause phytotoxicity to the normal vegetative growth of plants. In conclusion, the components in the raw pesticide are the agents with the effect of removing the flying cotton of the plants, and the agents are compounded with the auxiliary agents to form the agent of the invention, so that the effect of removing the flying cotton of the plants is realized.
Preferably, the sulfonylurea herbicides include 3- (4, 6-dimethoxypyrimidin-2-yl) -1- (2-methoxyformylbenzyl) sulfonylurea, 3- (4-methoxy-6-methyl-1, 3, 5-triazin-2-ylcarbamoylsulfamoyl) thiophene-2-carboxylic acid, methyl 2- [ 4-methoxy-6-methyl-1, 3, 5-triazin-2-yl (methyl) carbamoylsulfamoyl ] benzoate, 2- (4, 6-dimethoxy-2-pyrimidylcarbamoylsulfamoyl) -N, N-dimethylnicotinamide, 5- (4, 6-dimethyloxypyrimidin-2-ylcarbamoylsulfamoyl-1-methylcarbamoylsulfamoyl) -1-methylcarbamoylsulfonyl Pyrazole-4-carboxylic acid ethyl ester, 1- (4, 6-dimethoxypyrimidin-2-yl) -3- (3-trifluoromethyl-2-pyridinesulfonyl) urea, 1- (4, 6-dicarbamimidol-2-yl) -3- (3-ethylthio-2-pyridylthio) urea, 2- (4, 6-dimethoxypyrimidin-2-ylaminocarbonylaminosulfonyl) -a- (methanesulfonamido) p-methylbenzoate.

wherein A is-COOH, X is N, and R1 and R2 are methyl and isopropyl, respectively. 2- [4, 5-dihydro-4-methyl-4- (1-methylethyl) -5-oxo-1H-imidazol-2-yl ] -5-ethyl-3-pyridinecarboxylic acid, also known as Imazethapyr, is a highly effective herbicide of the imidazoiinone class, acting by inhibiting the ALS enzyme, being absorbed by the roots and leaves of weeds, conducted in the plant, causing weeds to stop growing and then die. The research and the application of the plant flying cotton and fly wool in the aspect of thinning and removing are not found.
Preferably, the triazolopyrimidine herbicide is 2 ', 6' -difluoro-5-methoxy-8-fluoro [1, 2, 4] triazolo [1, 5-c ] pyrimidine-2-sulfonanilide.
By adopting the technical scheme, the 2 ', 6' -difluoro-5-methoxy-8-fluoro [1, 2, 4] triazolo [1, 5-c ] pyrimidine-2-sulfonanilide, also known as florasulam (florasulam), is a systemic conduction type herbicide and can be conducted to the whole weed, so that the weed is thoroughly killed without relapse. The florasulam has a wide herbicidal spectrum, can prevent and kill most broad-leaved weeds in wheat fields, including cleavers (Rubiaceae), mai-jia (Boraginaceae) and other difficult-to-prevent weeds, and has a very good inhibiting effect on euphorbia helioscopia (Euphorbiaceae) which is the most difficult-to-prevent weeds in the wheat fields. The research and the application of the plant flying cotton and fly wool in the aspect of thinning and removing are not found.
Preferably, the dosage form of the medicament is: wettable powder, water dispersible granules, suspending agents, micro-emulsions, micro-capsule suspending agents, aqueous solutions, aqueous emulsions or missible oils.
By adopting the technical scheme, the medicament is prepared into various dosage forms, different dosage forms can be selected according to different application occasions and environments, the application range is wider, and the applicability is stronger.
The second purpose of the invention is to provide the application of the medicament for thinning plant flying cotton and fly in the thinning of plant flying cotton and fly, so that the flying cotton of willow, poplar, sycamore and other plants can be thinned, the fruits of the plants can not normally grow and fall off, and the effect of thinning, preventing and controlling is achieved.
The second purpose of the invention is realized by the following technical scheme:
the application of a medicament for removing plant flying cotton and fly is to spray the medicament on leaves of a plant in a spraying way, wherein the spraying time is from the beginning of the bud period or inflorescence expanding period of the plant to the beginning of the flowering period or the beginning of the elongation of the inflorescence, the pesticide application is stopped, 0.2g/L-20g/L of the medicament is sprayed on the leaves for 1-2 times, and the pesticide application interval is less than 15 days; wherein, 0.2g/L-20g/L is the concentration of the spray solution after the medicament is diluted.
Preferably, the medicament is injected into the trunk of the plant by an injection mode according to the injection concentration of 0.1g/cm-5g/cm breast diameter, the application time is from the beginning of the bud period or the inflorescence expanding period of the plant to the beginning of the flowering period or the beginning of the elongation of the inflorescence, the application is carried out for 1-2 times, and the application interval is less than 15 days.
By adopting the technical scheme, the plant to be thinned and removed of the flying cotton and the flying hair enters the budding period or the inflorescence expanding period in a spraying or injection mode until the plant enters the initial flowering period or the inflorescence begins to extend, so that the plant fruits can not normally develop and fall off, the control effect is good, and the plant self-growth is safe and harmless. The pesticide application operation is simple, and is convenient for basic greening workers to master and implement, thereby facilitating large-scale popularization and use.
The medicament for thinning out plant flying cotton and fly has the action mechanism of inhibiting the growth of plant flower buds to inhibit the formation of flying cotton and fly or fruit hairs, so the medicament is applied to the poplar and willow at the beginning of the flowering bud expansion period when the flower buds enter the inflorescence expansion period and the plant begins to elongate after entering the inflorescence, and the aim is achieved. When the plants such as the poplar, the sycamore and the like enter an inflorescence expanding period or a bud period, the pesticide is injected into a trunk or sprayed onto leaves, the pesticide is diffused to each part of the tree along with plant transpiration and leaf absorption, the flower bud development of the tree is inhibited, fruits are aborted or cannot grow normally and fall flowers and fruits, and the pollution and harm caused by flying cotton wool or fruit wool are reduced.
In conclusion, the invention has the following beneficial effects:
(1) the flying-cotton-like hair or fruit hair treatment period is controlled to be in the flower bud development period by inhibiting the development of plant flower buds to cause fruit abortion or the fruit falling due to abnormal growth and development, so that the flying-cotton-like hair or fruit hair treatment period is fundamentally solved;
(2) all the components of the medicament are beneficial and harmless to plant growth, and only have an inhibiting effect on flower bud development; while inhibiting the flower bud development, the nutrient consumption of the plant in the aspect of reproductive organ growth can be relatively reduced, so that more nutrients are used for plant growth, and the plant growth vigor is better;
(3) the preparation is prepared into different dosage forms, the application method is simple, and the greening personnel can conveniently master and implement the application method;
