Abstract
The invention relates to the technical field of pesticides, in particular to an insecticidal composition containing farnesol. The insecticidal composition containing the farnesol is characterized in that the active ingredients of the insecticidal composition are formed by binary combination of abamectin, butene fipronil, epoxy insect or pymetrozine and the farnesol. The insecticidal composition has different insecticidal mechanisms of farnesol and other active ingredients, and can effectively delay the generation of drug resistance of pests and prolong the service life of the insecticidal composition when being compounded for use. In addition, when the active ingredients in the insecticidal composition are compounded, the synergistic effect is shown on preventing and controlling aphids, the preventing and controlling effect on aphids can be improved, the use amount of the active ingredients is reduced, and the preventing and controlling cost of pests is reduced; meanwhile, the compound pesticide can provide support for the comprehensive control of aphids and the development of novel chemical agents for controlling the aphids.
Description
Technical Field
The invention relates to the technical field of pesticides, in particular to an insecticidal composition containing farnesol.
Background
Farnesol, english name Farnesol, CAS number: 4602-84-0, molecular formula: c (C) 15 H 26 O has the following structural formula:
farnesol is the main component of essential oil of spice plant farnesol type Cinnamomum tenuifolia Cinamomum tenuipilum Kosterm, has complex biological activity on various arthropods, and can influence insect development as one of the components of insect juvenile hormone. The combined killing effect of the farnesol and the nicotine on the apple yellow aphid is determined by taking the apple yellow aphid as a test pest in (Li Zhenxi and the like, chinese biological control theory report, 2 months in 2019, 35 (1) 37-43), and the obvious aphid killing synergistic effect of the farnesol and the nicotine is found.
Aphids, known as tired or honey worms, belong to the class of Arthropoda, the order of hemiptera, currently known in the world are nearly 5000 aphid species, and more than 1000 species are found in China. On one hand, aphids directly harm plants by piercing plant juice or releasing toxic substances, and normal physiological metabolism and growth and development of the plants are affected; on the other hand, aphids are a transmission medium for plant pathogens, and most of the extremely common viral diseases of plants are transmitted by aphids, which also increases the damage of aphids to plants.
At present, chemical pesticides are still dominant in aphid control, but long-term application of a single chemical agent easily causes drug resistance of pests, and meanwhile, pesticide residues, environmental pollution and other problems are caused. The existing aphids, such as the myzus persicae, have developed different degrees of resistance to the existing chemical pesticides.
The compounding of pesticide active ingredients with different action mechanisms is an effective and quick way for developing new pesticide products and preventing and controlling pest and disease resistance at present. After the different pesticide active ingredients are compounded, three action types are shown: additive action, synergistic action and antagonistic action. The inventor finds that the abamectin, butene fipronil, epoxy insect or pymetrozine and farnesol have synergistic effect on preventing and controlling aphids when being compounded through a large number of indoor experiments, and can provide support for the comprehensive prevention and control of aphids and the development of novel chemical agents for preventing and controlling aphids.
At present, no related report of related compounding exists.
Disclosure of Invention
The invention aims to provide an insecticidal composition containing farnesol, which solves the problems existing when a single chemical agent is used.
In order to achieve the above purpose, the present invention provides the following technical solutions:
the first aim of the invention is to provide an insecticidal composition containing farnesol, and the active ingredients of the insecticidal composition are formed by binary combination of abamectin, butene fipronil, epoxy insect line or pymetrozine and farnesol.
Preferably, the mass ratio of the abamectin to the farnesol is 1-9:10-1.
Preferably, the mass ratio of the butene-fipronil to the farnesol is 1-25:5-1.
Preferably, the mass ratio of the epoxy insect-shaped agent to the farnesol is 1-7:30-1.
Preferably, the mass ratio of the pymetrozine to the farnesol is 1-15:3-1.
A second object of the present invention is to provide an insecticide consisting of the insecticidal composition containing farnesol and auxiliary ingredients which are allowed to be added in agro-pharmaceutical terms.
Preferably, the mass of the insecticidal composition containing farnesol accounts for 0.75-80% of the total mass of the insecticide.
Preferably, the pesticide is in the form of wettable powder, water dispersible granule or suspending agent.
A third object of the present invention is to provide a foliar fertilizer consisting of the pesticide and a water-soluble fertilizer selected from one or more of potassium sulfate, ammonium chloride, potassium nitrate, zinc sulfate and sodium octaborate tetrahydrate.
Compared with the prior art, the invention has the following beneficial effects:
(1) The avermectin in the insecticidal composition provided by the invention interferes with neurophysiologic activity, and stimulates release of gamma-aminobutyric acid, and the aminobutyric acid has an inhibitory effect on nerve conduction of arthropods;
the butene fipronil has the action mechanism of preventing the metabolism of chloride controlled by the insect gamma-aminobutyric acid and has high insecticidal activity on insects such as aphids, leafhoppers, plant hoppers and the like;
the imidacloprid has the effect of selectively inhibiting the nicotinic acetylcholinesterase receptor of the insect nervous system, and is a high-efficiency neonicotinoid insecticide;
pymetrozine can specifically block feeding behaviors of insects, so that the pests with the drugs stop feeding immediately, and the pests can move, but finally die from hunger due to irreversible feeding refusal;
farnesol, one of the components of insect juvenile hormone, can affect insect development.
From the above, the insecticidal composition has different insecticidal mechanisms of farnesol and other active ingredients, and can effectively delay the generation of drug resistance of pests and prolong the service life of the insecticidal composition when being used in a compounding way.
(2) When the active ingredients in the insecticidal composition are compounded, the synergistic effect is shown on preventing and controlling aphids, the preventing and controlling effect on aphids can be improved, the use amount of the active ingredients is reduced, and the preventing and controlling cost of pests is reduced; meanwhile, the compound pesticide can provide support for the comprehensive control of aphids and the development of novel chemical agents for controlling the aphids.
