Technical Field
The invention belongs to the technical field of pesticide compounding, and particularly relates to an insecticidal composition of spirotetramat and deltamethrin and application thereof.
Background
In the process of agricultural pest control, chemical control is still the most effective means for guaranteeing agricultural production, but the resistance development of pests is not ignored, and pesticide compounding is an important way for improving the control effect and delaying the resistance development of pests.
Deltamethrin is one of the most virulent pyrethroids insecticides, has the effects of contact killing and stomach poisoning, rapid contact killing effect, strong knockdown force, no fumigation and systemic effect and has a repelling effect on some pests at high concentration. The pesticide has long lasting period and wide insecticidal spectrum, and has good killing effect on various pests such as Lepidoptera, Orthoptera, Thysanoptera, Hemiptera, Diptera, Coleoptera and the like.
The systemic insecticide Spirotetramat (Spirotetramat) is a novel tetronic acid compound, can move upwards and downwards in the whole plant body after being applied, and the unique systemic property can protect newborn stems, leaves and roots and prevent eggs and larvae of pests from growing. Due to the unique action mechanism, the insecticidal composition can effectively prevent and control pests which have resistance to the existing insecticide, and has wide insecticidal spectrum and long lasting period.
Spirotetramat causes larva death by interfering with fat biosynthesis of insects and reduces reproductive capacity of adults, while deltamethrin acts by delaying closing of a sodium (Na) gate, resulting in sodium ions (Na)+) Increased influx, prolonged time, and potassium ion (K)+) Delayed outflow time, prolonged negative post-potential, depolarization of the axon membrane, and spirotetramat has good persistence but poor fast-acting propertyDeltamethrin has a fast knockdown property. Therefore, the spirotetramat and the deltamethrin are compounded, so that the compound pesticide has good quick-acting property and lasting property, effectively exerts the advantages of a single agent, makes up for the defects of the single agent, reduces the application dosage of the single agent, improves the use safety of the single agent, delays the generation and development of the drug resistance of pests, and meets the development requirement of pesticide application reduction and synergism.
Disclosure of Invention
The invention aims to solve the technical problem of providing an insecticidal compound containing spirotetramat and deltamethrin and application thereof.
The invention solves the technical problems through the following technical scheme:
the insecticidal composition is prepared by binary compounding of spirotetramat and deltamethrin, wherein the mass ratio of the spirotetramat to the deltamethrin is 1-50: 50-1, and further research shows that the synergistic effect is good when the mass ratio of the spirotetramat to the deltamethrin is 1-25: 25-1.
The insecticidal composition also contains auxiliary components of pesticide preparations so as to prepare formulations suitable for agricultural use. The auxiliary components of the pesticide preparation are one or more of a solvent, a filler, an emulsifier, a dispersant, a wetting agent, a binder, a lubricant, a stabilizer, an antifreezing agent or a film-forming agent.
The insecticidal composition can be prepared into any dosage form suitable for agriculture according to a method known by technical personnel in the technical field, and the better dosage form can be a suspending agent, a water dispersible granule, an aqueous emulsion, a granule or a seed coating agent.
The application of the insecticidal composition can be applied to the preparation of pesticide preparations for controlling grub or/and rice leaf rollers and other pests.

The experimental method comprises the following steps:
an indoor bioassay method for rice leaf rollers comprises the following steps: the toxicity of the spirotetramat and the deltamethrin in different mass ratios to the larvae which are just hatched by the rice leaf roller is determined by a rice seedling soaking method.
An indoor bioassay method for peanut grubs comprises the following steps: according to the soil mixing method introduced by Xiening and Yijuping, the grub is fed with sprouted peanuts, and the toxicity of the different mass ratios of the spirotetramat and the deltamethrin to the grub (3-year-old larvae) is measured.
The combined virulence evaluation method comprises the following steps: the spirotetramat is used as a standard medicament A, the deltamethrin is used as a test reagent B, the co-toxicity coefficient (CTC) of the two medicaments is calculated by adopting a Sun Yunpei method, and the judgment standard of the synergistic effect of the mixed medicament formula is as follows according to the regulation of agricultural chemical verification of Ministry of agriculture: the co-toxicity coefficient is more than 120, so that the synergistic effect is achieved; the co-toxicity coefficient is 80-120, which is additive effect; the co-toxicity coefficient is less than 80, and the synergistic ratio is determined for the antagonism.
The experimental results are shown in table 1 and table 2.
