Description
Technical Field
The invention belongs to the technical field of pesticides, and particularly relates to a selenium-enriched insect-resistant active plant pesticide.
Background
Oxazamate is a racemate, and the English common name is: dimropyridaz; CAS:1403615-77-9; the molecular formula: c (C) 16 H 23 N 5 O; relative molecular mass: 301.39; the structural formula is as follows:
according to the latest classification of the international pesticide resistance action committee (IRAC), oxaziclomefone belongs to group 36 and is a chord tone regulator, the action of the chord tone regulator is inhibited by blocking signal transmission of the upstream of a Transient Receptor (TRPV) channel of vanillic acid, hearing, balance force, direction sense, gravity sensing, movement ability and the like of pests are interfered, so that toxic pests lose coordination, cannot eat and finally die.
The oxazine amide has better systemic conductivity, can prevent and treat lepidoptera, coleoptera, diptera, hemiptera, thysanoptera and other ptera, cockroaches, ants and other pests, is environment-friendly to soil, aquatic organisms and the like, and is harmless to beneficial insects and birds such as powdery insects. Although the oxazin-mefenoxam has the above advantages, it is used as a chemical agent, if it is used as a single ingredient for a long time, it is liable to cause the generation and development of drug resistance of pests, resulting in a decrease in its control effect. The screening of the compound formulation with the oxazine amide can reduce the drug resistance risk of the oxazine amide and improve the control effect on target pests, so that the development of the compound formulation with the oxazine amide is necessary.
Beet armyworm (Spodoptera exigua H ubner) belongs to the genus Lepidoptera, and has a wide host range, including various crops of Solanaceae, liliaceae, cucurbitaceae, brassicaceae, etc. The beet armyworm clusters the leaf back of the host plant with larvae, and the leaf is chewed by the silk-laying net, and the damaged leaf is in the shape of a notch, hole or net, which seriously affects the yield and quality of the host. The effective prevention and control of the damage of asparagus caterpillar has become a problem to be solved in production.
The prevention and control of asparagus caterpillar in current production is mainly chemical prevention and control, such as indoxacarb, pyrethroid, emamectin benzoate, chlorantraniliprole, spinosad and the like. However, with the gradual generation and enhancement of drug resistance of asparagus caterpillar, the control effect of the existing various chemical agents is gradually reduced, and the control effect is not ideal. Therefore, development of a novel efficient medicament for preventing and controlling asparagus caterpillar is necessary.
The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art.
Disclosure of Invention
The invention aims to provide a selenium-enriched insect-resistant active plant pesticide, which aims to solve the problem of drug resistance of single component using oxaziclomefone.
In order to achieve the above purpose, the present invention provides the following technical solutions:
an insecticidal active ingredient, wherein the insecticidal active ingredient is prepared from oxaziclomefone, fluopyram, cycloxaprid or ivermectin according to the proportion of 1-200:200-1 by weight ratio.
More specifically, the mass ratio of the oxazine amide to the fluopyram is 1-15:6-1.
More specifically, the mass ratio of the oxazamate to the cycloxaprid is 1-8:30-1.
More specifically, the mass ratio of the oxazamate to the ivermectin is 1-20:20-1.
On the basis of the above, the invention also provides a selenium-rich and insect-resistant active plant pesticide which is prepared by taking the insecticidal active ingredient as an effective ingredient and adding sodium selenite and auxiliary ingredients which are allowed to be added in the pharmacy.
